The following load cases are recommended when analyzing a cold spring system: Cold spring is allowed to reduce the magnitude of equipment loads because, often, only a single application of a large load is sufficient to cause damage to rotating machinery. Cold spring does not change the “range” of stresses that the piping system is subject to, and so, no allowance is given for stress reduction.

Type F: The spring support is designed to support piping from below, directly from the floor or supporting steel. Adjustment is made by inserting a bar into holes in the load column and turning the load column as a jackscrew.

In such a case a flexible support (springs) is provided which is capable of taking the load in all the operating and cold conditions. The spring supports provides continuous support during expansion or contraction of the pipe.

Cold spring is beneficial in that it serves to balance the magnitude of the reaction under initial and extreme displacement conditions The cold load is shown below on this variable spring support and is indicated by the white diamond at the bottom of the pressure plate.

Spring hangers and supports should be set in such a way that the spring load and the piping weight correspond with the cold load position. The corresponding hot load position results from the theoretically determined pipe movement (travel) and the spring rate.

The weight the spring has to support while the pipe line system is in operation. Cold load / Cold setting / Installed load The weight the spring has to support while the pipe line system is NOT in operation. This is also called pre-set load. Movement / Travel The measure of a vertical travel distance of the pipe which is supported by the spring when the pipe line is in operation. Movement / Travel …

Pipe displacement can also be achieved by displacing supports in the vicinity of cold spring using hoists or adjustable supports. Stress engineer shall provide the movement of each of the restraint as required. This must appear on isometric or support drawings.Author: Anup Dey

Cold spring is the intentional stressing and elastic deformation of the piping system during the erection cycle to permit the system to attain more favourable reactions and stresses in the operating condition.Author: Anup Dey

Jul 16, 2003 · Cold Springing, reduces the max thermal loads (and stresses) in a system, by introducing a predetermined stress in the pipe when it is cold. Its main purpose is to reduce the peak loading on connecting equipment. However it does not effect the overall stress range, and therefore it cannot be used in the stress range equations.

Spring hanger & supports usually use Helical coil compression springs. The springs are manufactured either by the cold coiling process (where wire diameter is less than 12 mm) or by Hot coiling process Springs are classified as “Light” & “Heavy”.
