277 Pipe Roll w/ Cast Iron Base Plate

Size Range: 2" through 24" Material: Cast iron roll and plate Finish: Plain, Zinc Plated (Hot-Dip Galvanized optional) or Resilient Coated Service: For support of pipe where small longitudinal movement due to expansion and contraction may occur and where no vertical adjustment is required. Maximum Temperature: 400° F at roller, 300° F at resilient coated roller. Approvals: Complies with Federal Specification A-A-1192A (Type 45), WW-H-171-E (Type 46), ANSI/MSS SP-69 and MSS SP-58 (Type 45). Installation: Consist of sitting the unit in place. Weight of pipe and material hold unit in place. How to size: If 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. Features: An economical, practical means of supporting pipe with limited horizontal movement due to expansion and contraction. 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. Ordering: Specify pipe roll size, figure number, name and finish. Be certain to order oversized rolls when insulation and protection saddles are required. Note: Fabricated carbon steel base plates for extended travel are available upon request. Refer to Fig. 75 SD and 76 SD for additional pipe roll designs.
