Component illustrations, part numbers, materials, dimensions, Q.A. Uniform load & deflection data to aid in the selection of catalog tray sections Information to assist with I&C engineering & 3D layout design From an extensive list of typical solid stainless-steel tube/pipe clamp sizes Build-to-Print according to customer specifications, "partnering" I&C workshops, design/installation collaboration, trouble-shooting Low-voltage electronic, fiber optic, coaxial classification considerations

Application

    

What line types (tube, pipe, cable, optic, bundles)?

How many lines are to be run together?

Tube/pipe outside diameter/ovality tolerances?

Debris/corrosion exposure, vibration factors?

Thermal expansion conditions (line/tray movement)?

Minimum bend radii for turns?

Tube/pipe stacking, spacers, guides, multi-line clamps?

Tube/pipe section tolerances may vary - clamp design options.

Material selection, clamping options, debris protection covers?

Clamp designs/clearances, tube expansion loops, tray expansion splices?

Support

     

Procurement

U.S. Code of Federal Regulations, Nuclear Regulatory Commission QA Requirements for Nuclear Facility Applications Qualified Material Organization (ref. NCA-3842.2) QA Program Requirements for Nuclear Facilities Canadian Standard Group, QA Program Requirements…Nuclear Audited by NUPIC & various ASME Certified Material Organizations Fabricated under the JCWCO Nuclear QA Program & Procedures

     

Quality level requirements?

JCWCO catalog part number specified?

Order quantity price breaks?

Direct shipped or distributor P.O. consolidation?

Concerned about component condition, consistency?

Dedicating commercial grade to safety-related?

Include QA & other special requirements on requests-for-quote.

Installation

POINTS TO CONSIDER

Components for pneumatic I&C applications to support tubing, pipe, & bundles Components for electrical I&C applications to support cable & bundles Fluid manifolds for instrumentation only Stand & rack supports for instruments, tray, manifolds, junction boxes Heavier clamps for varying degrees of tube/pipe movement (seismic & commercial)

   

Fasteners: bolts, hex nuts, washers, lock-nuts?

Post-installation visual field (walk-down) inspections?

Wall mount application for tubing, pipe?

No room for tray? NC/PC weld-down clamp bases?

How will signal lines & instruments be supported?

Channel/angle tray? 1", 2", 3" depth? Width? Length?

Channel/angle tray support span requirements?

Channel tray material, gage, finish?

Straight tray section splices required?

Tray turn fittings? Vertical, Horizontal, "T", Cross?

DESIGN CRITERIA & ULTIMATE GOALS  

Primary design criteria?

Ultimate financial goals?

QUALITY. RELATIONSHIPS. SERVICE

Instrument stands, racks, channel/angle tray, clamps, guides, straps?

Tray section for beam properties, tube-stacking, channel covers.

JCWCO Online Load & Deflection Calculator to facilitate catalog selections.

Compare aluminum, hot-dipped-galvanized carbon steel & stainless steel.

Cost-effective tray splices are frequently overlooked in requisitions.

Manufactured tray turn fittings minimize field cutting and welding.

Use JCWCO catalog part numbers to optimize communication.

Grouping multiple application needs may achieve price-break quantities.

Both are available. Material staging, blanket orders?

Avoid tray twist, shear burrs, misaligned bolt holes, zinc "spurs."

Compare seismic to commercial-grade prices, consider schedule costs.

Typically, assembly fasteners are included with tray-turn fittings.

Consider distinctive NC/PC anchor clamp chamfered-corner profile?

Consider three-bolt NC/PC clamp design?

Install tube/pipe clamps to existing structures with weld-down bases?

What is "Or Equal?" - On-schedule? Reliable installation? Quality result? No Problems?

Lowest prices? Lowest installed-cost? Lowest life-of-application cost? Cost-effective?
