The Pipe Stress model determines how the piping can be designed to move and avoid placing under stress on the nozzles to equipment and the piping itself. Having started as a Pipe Stress Engineering company, PT&P has deep experience in Pipe Stress Analysis. Spring Supports sizing is determined by a Pipe Stress Model which assesses the thermal growth and associated stress on the piping, nozzles, etc. Our constant support hangers are designed per MSS, ANSI, and ASME standards. The MSS standard provides for a tolerance of 6% in the constant load through the travel range. The cam is designed such that the distances from the main pivot changes to compensate for the variable resistance during compression of the coil. The constant resistance to a load is achieved by combining a spring coil with a cam which rotates about a main pivot point. If the variation exceeds 25%, a constant support hanger should be used. The maximum recommended variation according to MSS standard from the operating load is 25% for variable spring hangers. PT&Ps’ constant support hangers are principally used to support pipes and equipment subjected to vertical movement due to thermal expansion at locations where the transfer of stress to other supports or equipment can be critical. maximum recommended variation according to MSS standard from the operating load is 25% for variable spring hangers.

Order should include figure number, name and finish in all cases.Low coefficient of friction between pipe and resilient coated pipe roller.Corrosion resistant - for protection against severe weather conditions, moderate corrosive conditions such as marine atmospheres and weather resistant to ultra-violet radiation.Non conductive pipe rollers - prevent the passing of current from pipeline to structure.Pipe roll is designed for two point surface contact with pipe or saddle.įeatures: Advantages of pipe rollers with a protective resilient coated covering.Provides for vertical adjustment nut at bottom of hanger rod fits into the socket preventing loosening or turning due to vibration.160 – 166A submittals for size of pipe roll. If used with pipe covering protection saddle, see Figs.If the roll is to support non-insulated pipe, select the size directly from nominal pipe size (column 1) in the submittal table.
Maximum Temperature: 400° F at roller, 300° F at resilient coated roller. Service: For suspension of pipe from two rods where longitudinal expansion and contraction may occur.Īpprovals: 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).Īdjustment: Adjustable socket permits vertical adjustment at the roll.
