177 Adjustable Pipe Roll Support

Size Range: 1" through 30"

Material: Cast iron roll and sockets; steel roll rod, continuous thread rods and hex nuts

Finish: Plain, Zinc Plated (Hot-Dip Galvanized optional) or Resilient Coated

Service: For support of pipe where longitudinal movement due to expansion and contraction will occur and where vertical adjustment up to 6" may be necessary.

Maximum Temperature: 450° F at roller, 300° F at Resilient coated roller.

Approvals: Complies with Federal Specification A-A-1192A (Type 41), WW-H-171-E (Type 42), ANSI/MSS SP-69 and MSS SP-58 (Type 41).

Installation: Normally used directly above steel beams, brackets angles, etc.

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:

1. If roll is to support bare pipe, select the size directly from nominal pipe size.
2. If used with pipe covering protection saddle, see Figs. 160 – 166A submittals for size of pipe roll.
3. If roll is to support covered pipe, the O.D. of the covering should not be greater than the O.D. of the pipe for which the roll was designed.
