Coated Casing Spacers - Isolators (Model C)
 An extremely tough and durable heat fused fluid bed thermo set cross-linked polymer coating is offered on steel casing spacers/isolators 4" and larger, with 8" and 12" band widths. The cold formed steel casing spacer/isolator band (risers where applicable) and studs for runner mounting are grit blasted, heated and fusion coated with a cross-linked epoxy polymer formulation, providing a minimum 0.010 (0.254mm) thick coating over the entire metallic surface. A post cured cycle strengthens the bond and provides an even more uniform coating.

Other heat fused formulations are also available for custom orders and applications.
The runners are attached with 3/8" diameter studs, which are fusion welded to the band before it is powder coated. They are recessed far below the wearing surface of the runner. After the runner is anchored to the band, the stud counter-bore is filled with specially formulated caulk to assure a water tight seal for the stud and the locking fastener.

 

 Targeted Use - Energy, Water and Filled Casings
  • For carrier pipe diameters ranging from 4" (101.6mm) to 120" (304.8cm).
  • For carrier pipe insertion lengths up to 5,000 feet* (1,524M)
  • Spacing Recommendations: Max 8' (243.8cm) between spacers, Max 2' (61.0cm) from casing pipe end, Max 2' (61.0cm) on each side of bell or mechanical joint.
  • Recommended End Seals: Model C, S, W, R and FW.

*Pipe insertion lengths may vary depending on type of casing pipe, condition of casing pipe or other factors that may cause excessive abrasion to runner materials.

Effective Runner Heights and Lengths - G and GN
Sizing carrier pipe O.D. and casing I.D. can be misleading at times due to a difference between nominal and effective dimensions. When sizing, make sure to consider effective runner height. Two heights are available/used; custom positioning in the casing can be achieved with riser heights.

Heights - Nominal Versus Effective
2" Wide Glass Reinforced Nylon or Polyester Runners

Nominal = 1.0" (25.4mm) - 1.5" (38.1mm)
Effective = 1.07" (27.2mm) - 1.70" (43.2mm)

Lengths - Effective
2" Wide Glass Reinforced Nylon or Polyester runners

7.0" (177.8mm) - 11.0" (279.4mm)

Glass reinforced polymer runners are standard in 2" (50.8mm) widths for Model C (coated). PSI GN glass reinforced nylon runners have 5 times the compressive strengthof polyethylene runners. Our Model G polyester 2" wide runners are particularly designed for heavier pipes and longer pulls.
