The new generation of PVC-O pipes

Excellence in high-pressure water piping

UUU TECHNOLOGY

Molecular Orientation, a revolution in PVC TOM PVC-O pipes are the most advanced pipes for the conveyance of high-pressure water currently available on the market, with a number of exceptional features for this kind of application, thanks to the process of molecular orientation. PVC is essentially an amorphous polymer in which the molecules are located randomly. However, under certain conditions of pressure, temperature and speed, and by stretching the material, it is possible to orient the polymer molecules in the same direction as which the material has been stretched. Depending on the process parameters used and mostly strecht ratio, a higher or When amorphous structure PVC (the lower section, green in color) is subjected to molecular orientation, it adopts a laminar structure (upper section, blue in color).

lower orientation degree will be obtained. The result is a plastic with a layered structure which layers can be seen at a glance.

EFFECT OF ORIENTATION ON THE POLYMERIC STRUCTURE

The molecular orientation process modifies the PVC’s structure by giving the polymer’s molecules a linear orientation.

A plastic with unbeatable properties The process of molecular orientation greatly enhances PVC’s physical and mechanical properties and gives it a number of exceptional features, without altering the advantages and properties of the original polymer. This makes for a plastic with unbeatable qualities in terms of resistance to traction and fatigue, flexibility and impact resistance. When used in high-pressure water pipelines this type of piping is virtually indestructible and has an extremely long lifetime. Moreover, the pipe is highly energy-efficient and eco-friendly not only for the way it is made but also because of its subsequent use. Other advantages include reductions in costs and installation times. For all these reasons, TOM PVC-O pipes are the best solution for medium and high pressure water networks for irrigation systems, potable water supply, fire extinTOM pipes.

guishing networks and pumping systems, among other applications.

TECHNOLOGY UUU

Cutting-edge technology for water TOM PVC-O pipes have been developed by MOLECOR, the only company in the world conceived and dedicated entirely to researching and manufacturing PVC-O pipes. Our manufacturing process is absolutely innovative and uses the most advanced and most reliable technologies currently available. Up until now, although PVC-O pipes are recognized as providing the highest specifications, the technical limitations of the different manufacturing processes and the shortcomings of those processes in terms of efficiency were a barrier to the extensive use of this kind of pipes. The technology developed by MOLECOR means that these limitations have now been overcome and it has also helped to make considerable improvements in TOM pipes. UÊ Molecular Orientation is achieved by applying the precise and homogenous distribution of temperature and high pressures (up to 35 bars) thanks to quality control checks carried out on each individual pipe and throughout the entire manufacturing process. UÊÊThe TOM pipes manufacturing process is continuous and fully-automated (as opposed to the traditional discontinuous method), providing greater control over the end product and ensuring the uniform quality of each pipe.

Maximum Reliability and Security Thanks to the extraordinary technical advances of MOLECOR’s manufacturing system, TOM pipes offer the maximum reliability and security, as well as other attractive advantages over other products: UÊ Maximum Molecular Orientation: Class 500, according to the ISO 16422:2006 Standard, the highest orientation degree offering the best mechanical properties. UÊ Greater reliability of the end product. UÊ Strict dimensional tolerances. UÊ Homogeneous behavior of the materials used. UÊ Reinforced socket, shaped during the orientation process.

Manufacturing process developed by Molecor uses most advanced technologies and it is completely automatized. This gives TOM pipe maximum guarantee and quality.

TOM: The best choice for high-pressure fluid transport

Unbeatable impact resistance TOM pipes are virtually impossible to destroy by impact. This means that there are no breakages during installation or during on-site trials caused by dropping or by impacts from stones. Furthermore, Molecular Orientation prevents the propagation of cracks and scratches and eliminates the risk of rapid crack behaviour. The result is a spectacular increase in the product’s useful life.

High short- and long-term hydrostatic resistance TOM pipes offer a resistance to internal pressure of up to three times the nominal pressure (48 bars in PN16 pipes or 695 psi in PN 235), which means that they can bear sporadic excessive pressure such as water hammers and other malfunctions in the network. Moreover, the material creep behavior is very low, ensuring the durability of the pipe working at nominal pressure for over a hundred years.

Excellent response to water hammers TOM pipes offer lower celerity than other piping systems (four times less than ductile iron pipes), which means less water hammers caused by sudden variations in water volume and pressure. This reduces and almost eliminates the possibility of breakage during opening and closing in the water network and when pumping gets under way, protecting every component of the network.

Increased hydraulic capacity Molecular Orientation reduces the thickness of the pipe wall, giving TOM pipes a greater internal diameter and flow section. Also, the internal surface is extremely smooth, reducing load loss and making it more difficult for deposits to form on the inner walls. The impact of a 500 kg rock dropped from a height of 3 metres leaves a TOM pipe completely unscathed.

As a result, TOM pipes offer between 15% - 40% more hydraulic capacity than pipes made from other materials and with the same external dimensions.

A D VA N TA G E S U U U

Maximum flexibility Thanks to their excellent elasticity, TOM pipes can bear deformation of up to 100 percent of their internal diameter. When crushed, or in the event of a mechanical accident, TOM pipe immediately goes back to its original shape, thus eliminating the risk of potential breakage by soil subsidence or sharp edges on rocks or machinery, for example. And thanks to their considerable capacity for bearing heavy loads, TOM pipes ensure optimum performance once laid underground.

Completely corrosion-resistant Oriented PVC is immune to corrosion and to natural chemical substances, as well as to aggression from micro- and macro-organisms. TOM pipes, therefore, are not degradable. Moreover, they do not require any type of special protection or coating, which means cost-savings.

Total water quality

TOM pipes will take any kind of deformation without suffering structural damage.

The quality of the fluid that circulates in TOM pipes will always remain unaltered, given that the material does not suffer corrosion nor are there any migrations within the pipes or in their coating. Mandatory tests show that the excellent qualities of these pipes comply with the required health standards for water for human consumption. All this makes TOM pipes the best application for piping high-pressure water, particularly drinking water for water supply networks.

Completely water-tight

Locked-in ring seals ensure a perfect water-tight fit.

Joints are 100 percent watertight and are guaranteed not to displace once the pipes have been installed. TOM pipes are easy to join and can be installed by lower-qualified workers.

Lower cost and easier installation TOM PVC-O pipes are lighter and easier to handle than other pipes made from other materials: in most cases, handling does not require machinery. What’s more, because they are so easy to join and are so flexible and impact resistant, they make a positive difference in terms of cost, performance and installation speed compared to other kinds of pipes.

TOM pipes are extremely lightweight.

Unbeatable Hydraulic Properties Hydraulic capacity Water pipes not only have to be pressure-resistant: they also have to transport the highest amount of water while consuming the least amount of energy. TOM pipes’ walls are thinner than those of conventional plastic piping and are smoother inside than those of metal pipes, which means greater hydraulic capacity. Comparison of hydraulic capacity: TOM PVC-O PN16 pipes vs other materials (constant load loss)

Using pipes with a lower hydraulic capacity involves necessarily using a larger nominal diameter, which has a negative effect on both profitability and infrastructure investment costs. Using TOM means you get more hydraulic capacity for your investments costs. Hydraulic capacity/Piping costs compared to TOM PVC-O PN16 DN250

Water Hammer Water hammers occur when liquid flowing through piping stops suddenly when a valve is open or closed, if a pump is stopped or started or by airlocks shifting within the pipe. Water hammers can place greater pressure on a pipe’s working pressure and lead to breakage, particularly when the pipe has already been damaged by impacts or corrosion. Water hammers (P) depend on the celerity (a), which is the wave speed, and the fluid’s change of speed (V) The celerity depends basically on the pipe’s dimensions (the relationship between the external diameter and the minimum thickness) and the specifications of the material with which the tube is made (Young’s E module).

TOM’s PVC-O pipes have a significantly lower celerity than pipes made from other materials, particularly so with metal piping.

A range for all kinds of applications TOM offers a broad range of piping covering all medium- and high-pressure needs.

Applicable Laws and Standards TOM PVC-O pipes are manufactured in accordance with the ISO 16422:2006 standard applicable to “Pipes and joints made of oriented poly(vinyl chloride) (PVC-O) for the conveyance of water under pressure”. Other international standards applicable to PVC-O are as follows: U France: XP T54-948:2003 “Tubes en poly(chlorure de vinyle) orienté biaxial (PVC-BO) et leurs assemblages”. [Pipes and joints made of biaxially oriented polyvinyl chloride (PVC-BO) ] U USA: ASTM F 1483-05 “Standard Specification for Oriented Poly(Vinyl Chloride), PVCO, Pressure Pipe”; and “ANSI/AWWA C909-02 Molecularly Oriented Polyvinyl Chloride (PVCO) Pressure Pipe for Water Distribution.” U Australia: AS/NZS 4441:2008 “Oriented PVC (PVC-O) pipes for pressure applications.” U South Africa: SANS 1808-85:2004 “Oriented polyvinyl chloride (PVC-O) pressure pipes for underground use.” U Spain: UNE-ISO 16422 standard applicable to “Tubos y uniones de poli(cloruro de vinilo) orientado (PVC-O) para una conducción de agua a presión”.

Classification of material The ISO 16422:2006 standard covers several types of materials classified according to their MRS (Minimum Required Strength), because molecular orientation can be achieved to a greater or lesser extent through different manufacturing processes. TOM PVC-O piping is made only with the highest classes (PVC-O 450 and PVC-O 500), which offer the highest degree of orientation and thus ensure the best mechanical performance. Subsequently, TOM pipes offer even more of the advantages you expect from PVC-O, and much more so than pipes made from other materials.
