Size Range: 2-1/2" through 24"
Material: Cast iron roll; carbon steel yoke, roll rod and hex nuts
Finish: Plain, Hot-Dip Galvanized Yoke with Zinc Plated Parts or Resilient Coated
Service: For suspension of pipe from a single rod where longitudinal movement may occur because of expansion or contraction.
Maximum Temperature: 450° F at roller, 300° F at resilient coated roller.
Approvals: Complies with Federal Specification A-A-1192A (Type 43), WW-H-171-E (Type 44), ANSI/MSS SP-69 and MSS SP-58 (Type 43).
Features: Advantages of pipe rollers with a protective resilient coated covering.
- Non conductive pipe rollers - prevent the passing of current from pipeline to structure.
- Corrosion resistant - for protection against severe weather conditions, moderate corrosive conditions such as marine atmospheres and weather resistant to ultra-violet radiation.
- Low coefficient of friction between pipe and resilient coated pipe roller.
How to size: If the roll is to support bare pipe, select the size directly from nominal pipe size. If used with pipe covering protection saddle, see Figs. 160 – 166A submittals for size of pipe roll.
Ordering: Specify pipe roll size, figure number, name and finish. Be certain to order oversized rolls when insulation and protection saddles are required.
