superFLO

chilled and cold water pipework

Durapipe super FLO offers tremendous advantages for chilled water/air conditioning and cold water services in buildings: • Fully integrated range of pipes, fittings and valves (manual and actuated) • 50 year design life • Installed costs reduced • Non corrodible • Low maintenance • Robust and reliable • Lightweight • Tough and durable • Ductile down to minus 40°C • Exceptionally smooth bore • No scaling • Reduced noise compared to metal • Fast and reliable jointing • Low thermal conductivity

Corrosion resistance

When considering environment control systems, cooling medium distribution pipework is of prime importance.

The reliable containment and efficient movement of fluid in pipes is essential to every air conditioning system, from a self contained packaged unit to a full scale central plant scheme.

The inherent susceptibility to corrosion and thermal properties of metal piping materials such as copper and steel are often not suited to these arduous applications.

The corrosion resistance of the piping material is as important since the aqueous solutions used by such systems may be of a corrosive nature. These have highlighted the benefit of the corrosion resistance of Durapipe superFLO piping systems. Growing economical and environmental pressures have also made Durapipe superFLO piping the right choice.

Installation cost

Sustainable manufacture

As well as influencing system performance, pipework accounts for a large proportion of the total installation cost, making the right choice of pipes and pipe fittings vital. Durapipe superFLO can help reduce installation costs.

Growing environmental concerns have led to the adoption of ‘indirect cooling’ practices by the environment control industry as well as manufacturers and installers of packaged air conditioning equipment.

The energy used to make Durapipe superFLO thermoplastic pipe from raw material compares favourably with, for example, steel

pipe manufacture because lower conversion temperatures are needed.

Furthermore our processes are clean with low process emissions.

Durapipe superFLO pipe and fittings are cheaper and easier to transport because they are lighter in weight than the equivalent metal pipes. They can be recycled at the end of life into other products, and scrap during the manufacturing process can also be recycled and re-used. This minimises the need for any thermoplastic pipe scrap entering the waste stream.

Durapipe UK operates an environmental management system that has been successfully assessed against the BS EN ISO 14001 environmental management system standard.

superFLO Durapipe superFLO is manufactured from ABS, a copolymer of Acrylonitrile, Butadiene and Styrene, blended to give unrivalled properties, and offering benefits over traditional materials for significant water pipework.

Acrylonitrile imparts chemical resistance ensuring the pipework does not corrode or scale. The Butadiene content endows the material with impact strength and toughness particularly at low temperatures, while the Styrene content contributes to lustre, hence extremely smooth bores, and also ensures the strength of the material.

Durapipe UK is the most experienced and successful ABS pipework systems manufacturer in the world. The outstanding advantages of Durapipe superFLO make it the market leader.

superFLO

chilled and cold water pipework

Durapipe superFLO, unlike copper or steel, is free from corrosion.

Corrosion resistance No material deterioration means no costly pipe and fittings system repair or replacement.

Low installed costs The ease of handling and speed of jointing of Durapipe superFLO will generally result in the total installed cost being lower than for threaded, welded, or soldered metal systems.

superFLO

PVC-U

Impact resistant Durapipe superFLO is a ductile material, and remains ductile down to minus 40ºC. Impact damage is usually confined to scuffs or dents.

In severe cases there may be ductile tearing of the material.

In contrast, PVC-U and PVC-C are much less ductile, particularly at temperatures below +5ºC. A sufficiently hard impact can cause them to fragment.

Smooth bore, uninhibited flow

Superior flow Low fluid friction allows higher flow velocities than metal pipes, and also inhibits the formation of scale, with consequent savings in pump energy consumption, and reduced pressure drops.

Wide temperature range A major advantage of Durapipe

superFLO over other plastic systems is its ability to perform over a wide temperature range from –40ºC to +70ºC. (Note: usual precautions must be taken to prevent contents freezing.)

Quality approved Durapipe superFLO has a wide range of International approvals and is manufactured generally in accordance with BS EN ISO 15493.

Quality control

Certificate No. FM 34819

Our commitment to quality is reflected by our operation of an independently assessed quality management system registered under BS EN ISO 9001.

Durapipe superFLO undergoes a rigorous testing programme to assure its performance in service.

Durapipe superFLO offers consistency, reliability and complete reassurance to designer, installer and end-user.

Pressure drop due to friction in pipes conveying water can be determined using the Flow Nomogram on page 23.

The pressure drop at a given flow rate can be determined as follows: 1. Obtain the internal diameter of the pipe to be used by referring to the dimension table below: 2. Mark this diameter on Scale A. 3. Mark the required flow rate in litres per second on Scale B. 4. Draw a straight line connecting the points on Scales A and B and extend this to Scales C and D. 5. The velocity of flow in metres per second is determined from the intersection with Scale C. 6. The frictional head loss in metres per 100 metres of pipe can then be read off Scale D.

superFLO system design and installation Thermal expansion and contraction Thermoplastic materials have a greater co-efficient of thermal expansion compared with metals.

There will, therefore, be a greater change in length of the pipe run for any given temperature change.

Expansion and contraction can often be accommodated by using the natural flexibility of thermoplastic material, ie. at 90째 changes in direction, thus overcoming the problem with little or no additional expense (right).

Pipe anchors The direction of pipe movement can be controlled by the use of anchor points at strategic positions, as shown opposite.

Where there are no changes in direction (eg. a straight run along a corridor) it may be necessary to incorporate expansion loops (see right).

Expansion bellows If there is insufficient room for expansion loops it will be necessary to incorporate expansion bellows (see below). These must be of a suitable design to ensure correct operation with superFLO pipework.

Most manufacturers of these units will have products in their range designed for use with plastic pipework. Their advice on the correct selection and installation must be followed.

Calculating thermal movement superFLO pipe expands/contracts by 1mm/metre/10°C change in pipe temperature.

On chilled water and boosted cold water pipework, the greatest single change in temperature is generally that which occurs when the pipework is put into service, particularly when this is done during spring or summer.

Example:

Calculation:

What is the anticipated change in length of a 20 metre run of superFLO conveying chilled water? The system is in the UK and is expected to be ready for commissioning during July or August. The CHW flow will run at 6°C and will return at 12°C. It will be insulated after pressure testing and commissioning is completed.

Ambient temperature indoors will probably be in the range of 20°C to 30°C. Assume pipe temperature prior to commissioning as (worse case) = 30°C. Maximum change in pipe temperature will occur in CHW flow pipe, ie. 30 - 6 = 24°C. The change in length, therefore, (using “1mm/metre/10°C”) is 2.4mm/metre.

The change in length of a 20 metre run will be 2.4 x 20 = 48mm.

Answer: As the pipe cools from 30°C to 6°C it will contract by 48mm.

The length of unrestrained pipe at a 90° change in direction required to accommodate expansion or the leg length of an expansion loop can be calculated from the graph to the right. The example given below shows how to calculate leg length of an extension loop.

Example: Calculate the size of expansion loop required for a 90mm diameter pipe contracting by a length = 48mm.

Draw a horizontal line from the vertical section to meet the 90mm pipe gradient line.

Drop a perpendicular from the intersection point to the horizontal scale. The figure obtained is the free leg length of the loop required.

Hence, in this instance a loop measuring 1200mm long x 600mm wide will cater for movement.

superFLO system design and installation - jointing guide Durapipe superFLO pipes and fittings are designed for an interference fit. Although Durapipe superFLO solvent cement has good gap filling properties no attempt should be made to increase the clearance between the pipes and fittings.

Solvent cement welding offers a simple and quick means of constructing high integrity, leak-free joints.

The solvent cement operates by chemically softening the joint surfaces. Joint integrity will be greatly reduced if these surfaces are not clean and properly prepared.

Durapipe superFLO solvent cement must be used.

The jointing procedure detailed here must be followed.

This relates to the new “onestep” solvent cement. With this cement it is not necessary to abrade pipe or fitting.

An indication of the number of joints to be made per litre of cement is as follows: size (mm)

recommended container size

Stage 1 The pipe must be cut clean and square. A suitable wheel cutter will eliminate swarf.

Stage 2 Chamfer the end of the pipe using a coarse file or suitable chamfering tool. The chamfer should be approximately 45° by 3mm to 5mm depending on the pipe size.

Stage 3 Mark the pipe a known distance from the end and clear of the area to be cleaned. This mark should be used to confirm full insertion of pipe into socket of fitting.

Stage 4 Clean surfaces thoroughly with Durapipe Eco-cleaner using lint free cloth/paper towel.

Drying Times The drying times will vary with fit, amount of solvent cement applied, ambient temperature and working pressure. It is recommended that, wherever possible, joints of sizes up to 225mm are allowed to dry for at least 24 hours. Sizes 250 mm and 315mm require a minimum of 48 hours.

These guidelines are based on an ambient temperature of between

superFLO system design and installation Design of pipe supports and clips Pipe supports (eg. drop rods) should be sufficiently rigid to provide lateral restraint to the pipework, otherwise the pipes may ‘snake’. This will prevent the expansion loop from working correctly, and may even reduce the service life of the pipework.

Pipe clips must allow free, unrestricted, axial movement. The pipe clips shown on page 20 and 21 meet these requirements.

Pipe clips Some rubber lined clips contain harmful substances which can reduce the service life of the pipework. We recommend the use of pipe clips as shown on page 20 and 21.

Support centres The recommended distance between supports for superFLO pipes filled with water is given in the table above. This table is based on the thinnest wall pipe in each size.

The details shown are for horizontal pipes. For vertical pipes, support centres may be increased by 50%.

Pipe trays are available for sizes 16mm, 20mm, 25mm and 32mm.

These allow support distances to be increased to 2.0 metres

Anchor blocks below ground

Support of heavy equipment

For wholly solvent welded systems the pipework is pressure balanced and anchor thrust blocks are not required.

Large valves, strainers and other heavy equipment should always be independently supported to prevent undue loading onto the superFLO system. Durapipe valve support plates have been designed for this purpose and may be used in place of flange backing rings.

flexible hoses and metal threaded fittings super FLO ABS flexible hoses super FLO Flexible Hoses have been introduced in response to customer demand and are specially designed to allow direct connection from Durapipe super FLO pipework to operating equipment.

If pipework is either short of a connection or at a higher or lower level to ancillary equipment, the braided flexible hoses can be solvent welded to super FLO pipework and then connected to operating equipment using a female threaded connection, forming a durable, leak-free fusion.

Manufactured in 300mm and 600mm lengths as standard, with additional sizes available on request, super FLO Flexible Hoses come in a choice of 20mm, 25mm and 32mm diameters. With an internal hose made from EPDM rubber, super FLO Flexible Hoses are also compliant with BSRIA Flexible Hose Standard BG4/2004.

super FLO ABS metal threaded fittings A series of brass ended fittings offer the ultimate in performance capabilities and provide a highly reliable connection between pipework and ancillary equipment across a range of building services applications.

These fittings have been specifically developed to offer increased customer options in the threaded fittings range. The fittings allow direct metal to metal connection and the ability to be solvent welded to pipework also ensures the fittings provide a durable connection to operational equipment.

Available in metric sizes up to 63mm the latest addition offers male and female connection options, providing specifiers with increased flexibility when selecting fittings for a variety of uses within the building services market.

Manufactured in the same sizes, a new half-faced union is also available in the Durapipe super FLO range. In ABS material, the new product can be connected to metal valves and easily removed and replaced with no cutting required.

The half-faced union provides a male threaded adaptor for female ends.

superFLO using bushes, reducers, threaded adaptors and flanges Reducing bushes

The use of reducers

Reducing bushes offer a neat and simple method of reducing socket size in the minimum of space.

Care must be taken to properly prepare all jointing surfaces as recommended earlier, with the end of the bush being chamfered (unless a moulded chamfer is included).

All fittings have female ends, dimensionally controlled for solvent welding. In addition, reducers in the Metric series have controlled outside diameter at the larger end. This allows use as a male or female component, as illustrated.

25 x 20 x 16 reducer 110mm tee

110 x 90 20mm pipe 90 x 75

Example in the use of reducing bushes

Connections Plastics to metal There are several recommended methods to connect metal and plastic systems: Composite unions Flanges Male threaded fittings Female threaded fittings Plastics expand or contract more than metals for any given change in temperature. The practice of connecting plastic threaded fittings to metal threads is not recommended where the joint is likely to experience a temperature change of more than +/-5ยบC, otherwise leaks may occur.

superFLO threaded adaptors Female and male threaded adaptors have controlled inside and outside diameters on the plain end.

They can therefore be used as a male or female component.

Tightening torques for flange bolts in superFLO ABS piping systems

Connection to instrumentation Instrumentation connections can be made by drilling through pipe and socket where the material is at its thickest and tapping the hole to receive a threaded fitting, as shown below: Pipe size Connection size 16mm-63mm Use tees, reducing bushes and threaded fittings 75mm-110mm Max. tapping 1â „2" BSP. 125mm-140mm Max. tapping 3â „4" BSP. instrument 160mm & above Max. tapping 1" BSP. connection

Recommended Torque Values (Nm)

Such connections, if correctly drilled and tapped with full thread form will have full PN10 pressure rating.

Flanged joints

Flange bolting procedure

Stub flanges are available from 16mm to 315mm.

The correct galvanised mild steel backing ring and rubber gasket must be used with both types.

The following procedure is recommended for installing Durapipe superFLO flanges: 1. Inspect flange faces and ensure that they are clean and undamaged.

2. Check that the correct backing ring and rubber gaskets have been supplied. Durapipe supplies a matched system of flanges and backing rings.

3. Loosely assemble flanges. Ensure that flanges and bolt holes align and that the flange faces are parallel. Ensure that the gasket is correctly positioned between the flanges.

superFLO additional important information • Thermal insulation Some insulation products can contain substances capable of having a detrimental effect on thermoplastic pipework eg. Certain types of foam rubber insulations can cause pipes to fail where the ABS is conveying liquids at temperatures above 30°C. Recommended insulation – a list of some of the common types of insulation materials known to be suitable with ABS pipework are as follows; Fibre wool, such as ‘Rockwool’ Armaflex Class 1 HT Koolphen K Phenolic foam Polystyrene Note – the above list is not exhaustive – please contact our Technical Support Department if further assistance is required.

Some adhesives can also be detrimental. Do not bond insulation to ABS. (The comment also applies to any tapes, adhesives, or other substances used to secure the heating tape to the pipework.)

• Trace heating The selection of heating tapes with silicone rubber, woven wire, or woven polyester outer sheaths will eliminate the risk of plasticizer migration. These tapes are therefore preferred for use on thermoplastic systems.

• Freezing conditions Precautions should be taken to prevent contents freezing, as this can cause pipework to split.

Mono-ethylene glycol can be added to the system to lower the freezing point.

• Contact with fluxes Some fluxes can be detrimental to ABS. Care should be taken when soldering copper pipework directly above, or close to, ABS pipework.

• Buried pipes Do not lay ABS in contaminated ground eg. ‘brown-field’ sites.

Do not lay ABS in ground where spillages of chemicals may occur.

• Pipe contents identification Do not put self-adhesive labels directly on to pipe surfaces as this may be detrimental to pipe performance. It is recommended that some sort of barrier, such as aluminium foil, is placed between pipe and identification label.

• Thread sealants Some thread sealants can damage ABS. PTFE tape should be used when making threaded connections.

• Intumescent mastic and mastic sealants Certain mastic sealants are formulated with phthalates. Phthalates are known to be extremely aggressive toward ABS materials, and therefore confirmation of the suitability of any mastic sealant should be determined before being used in conjunction with ABS pipework.

• Resistance to U.V. (sunlight) Care should be taken to avoid exposure to U.V. light, e.g. sunlight, particularly during storage. Thus will cause discolouration and deterioration of the ABS material. Whilst this is a surface effect only it is recommended that precautions be taken to prevent this happening. If stored outdoors pipe should be covered with opaque sheeting. If installed outdoors it can be protected from the effects of U.V. be insulating or painting.

• Pipe clips It is important that the composition of pipe clips and their linings do not include substances which might have a detrimental effect upon the ABS pipe. Please check for suitability before use.

We strongly recommend the use of Durapipe Cobra clips for pipe sizes up to and including 160mm OD / 6”NB, wherever circumstances allow.

32

• Contact with synthetic oils Some synthetic oils are unsuitable for use with thermoplastic pipe systems. The main types of synthetic oils identified as being incompatible with thermoplastic pipe systems includes Esters, Polyalkylene Glycols, and Organic Phosphates.

It should be noted that some metal coil manufacturers use these oils in their manufacturing process. This is normally drained from the coil. If it is suspected that residues of oil may remain in the coil it should be filled with methylated spirits, then thoroughly flushed with water.

• Pressure surges Durapipe ABS pipework can withstand pressure surges within the limitations detailed within CP312 part 2:1973 and its amendment dated 1977.

On no account should pressure surges be allowed to exceed the maximum continuous working pressure.

Handling and Storage The high impact strength of Durapipe super FLO systems provides some protection against damage but care should be taken at all stages of handling, transportation and storage.

Pipe must be transported by a suitable vehicle and properly loaded and unloaded, e.g., wherever possible moved by hand or mechanical lifting equipment. It must not be dragged across the ground.

The storage should be flat, level and free from sharp stones.

Storage of loose pipes

Lengths Pipe lengths stored individually should be stacked in a pyramid not more than one metre high, with the bottom layer fully restrained by wedges. Where possible, the bottom layer of pipes should be laid on timber battens at one-metre centres. On site, pipes may be laid out individually in strings. (Where appropriate, protective barriers should be placed with adequate warning signs and lamps.)

Storage of bundles

Bundles Bundled packs of pipe should be stored on clear, level ground with the battens supported from the outside by timbers or concrete blocks. For safety, bundled packs should not be stacked more than three metres high.

Smaller pipes may be nested inside larger pipes. Side bracing should be provided to prevent stack collapse.

Similar precautions should be taken with fittings and these should be kept in protective wrappings until required for use.

Health and Safety at Work Act and COSHH Regulations

Jointing and installation Durapipe super FLO solvent

Attention is drawn to the requirements in the UK of this Act and to the 1988 Control of Substances Hazardous to Health (COSHH) Regulations. Durapipe cannot accept responsibility for accidents arising from the misuse of its products because of bad installation or incorrect application.

cement must be used exclusively for fabrication of the superFLO ABS system. Performance guarantees are null and void if other solvent cements are used.

Material safety data Material Safety Data sheets are available on our website.

Handling super FLO pipes and fittings Always adopt good storage and handling practice.

Advice is available upon request.

Storage and installation outdoors Care should be taken to avoid exposure to sunlight during storage.

This may cause discolouration and deterioration of the super FLO material. Whilst this is a surface effect only, it is recommended that precautions be taken to prevent this happening (other sources of UV light can have a similar effect).

If super FLO is installed outdoors we recommend that it is protected from the effects of sunlight.

superFLO additional important information Filling and flushing

Colour

When purchasing chemicals for either flushing or long-term system use, suppliers should be advised that this is for superFLO material. Guidance on the suitability of various system flushing or filling fluids with super FLO can be found in the Durapipe Chemical Data catalogue.

Durapipe superFLO products are a mid-grey colour, generally in accordance with BS5252, colour ref. 18 B 21 and RAL 7001.

The Durapipe superFLO Metric System is manufactured generally in accordance with the relevant international standards as shown below: ISO 15493 KIWA 49 and 549 DIN 8062 and 8063 Threaded fittings conform to the requirements of BS 21/DIN 2999/ISO7. Socket dimensions of Durapipe fittings for solvent welding comply with ISO/DIS 727-1.

Testing It is suggested that the following test procedure be followed, after joints have been allowed to dry for the appropriate minimum time (at least 24 hours up to 225mm, sizes 250mm and 315mm require a minimum of 48 hours at 20°C).

The system should be divided conveniently into test sections.

Fill section with cold water making sure that no air pockets remain. Do not pressurise at this stage.

Check system for leaks. If none are apparent, check for and remove any remaining air. Increase pressure up to 3bar. Do not pressurise further at this stage.

Leave section pressurised for 10 minutes. If pressure decays, inspect for leaks and rectify as necessary. If pressure remains constant, slowly increase the hydrostatic pressure to 11/2 times nominal operating pressure.

Leave section pressurised for a period not exceeding 1 hour.

During this time pressure should not change.
