These stops must be removed during installation while the cold load is on the spring. Thus, hydro testing must be done with the stops in place. While these are in place, loads applied to the unit, such as hydro-testing loads, will not be transferred to the spring coil. The travel stops are painted red, and are held in place with stainless steel shipping bands, as shown in Figure 2. During assembly the coils of the variable springs are pre-compressed to the cold load position and travel stops are installed. More information on the individual types may be found in our pipe supports catalog or on our Web Site,. The primary difference between the types is in the manner in which they are supported, and thus the details of installation will be different for each type. There are seven types of variable spring hangers, designated by the letters A-G.

NOTE: Pipe clamp can be fabricated to any specified material.ĬHART A - STRESS-TEMPERATURE CORRECTION FACTORS ORDERING: Specify pipe outside diameter, total load, design temperature, material and dimension “D” or center to center of hanger rods. The bolt diameter is obtained by using the uncorrected total load and referring to “CHART B (below)”. ![]() Directly above this point is the required stock size.ĥ. Project this point horizontally until it intersects with the “D” dimension coordinate. Refer to “CHART C (below)” and locate the point determined by the intersection of the total load co-ordinate and the pipe size curve. Multiply total load by the correction factor to obtain a corrected load.Ĥ. Refer to “CHART A (table below)” and determine the temperature correction factor for the clamp material being used.ģ. ![]() ![]() Determine total load to be supported and service temperature of the piping system.Ģ. Temperature correction factors listed in “CHART A” are based on allowable stresses listed in MSS-SP-58.ġ. In situations where the use of a welded lug attachment would create an undesirable crushing effect on the pipe wall, this clamp can transfer the load from the pipe wall to the riser clamp by means of hold-down lugs welded to the pipe.Ĭlamps may be furnished in either Carbon or Alloy steel with bolting to suit, using an allowable stress of 10,000 PSI. ORDERING: Specify figure number, pipe size, description and finish. SERVICE: Recommended for suspension of cold pipe lines or hot lines where little or no insulation is required. 50: Light Two Bolt Pipe ClampįINISH: Black or galvanized furnished black unless otherwise specified.
