Essentials of Cold Spring in Piping System

Posted: Dec 01, 2019
It is usual for any material to expand or collapse their shape due to the change in temperature. It is a tendency of most of the matters to develop in the heat and contract in the cold temperature. And, pipes don’t possess immune to the laws of nature. One of the tremendous dynamic forces applied to the piping system is due to thermal expansion and contraction of pipes. What is Cold Spring in Piping System? Cold spring or Cold pull is a method used to compensate for the effect of thermal expansion in long pipe runs. It is an intentional distortion applied while assembling the piping system to generate the required amount of displacement and strain. If cold spring used appropriately, it balances the magnitude of stress under initial and extreme displacement conditions. It reduces hot stress and hot reaction forces generated due to thermal expansion.
Application of Cold Spring on Piping System:
Therefore, cold spring usage is mostly preferred for piping materials possessing limited ductility. The cold spring technique is generally not considered to be sufficient to get the desired results. Stress Engineers do not recommend extensive use of it. However, most of the EPC companies do not prefer the use of Cold Spring for the piping system because of its limitations. Drawbacks of Cold Pull:
Hence, there are lots of challenges and drawbacks when it comes to stress analysis in piping system. If you’re looking for a practical solution of stress analysis in Oil & Gas, Energy & Utility, Petrochemical & Refinery, or any other power companies, consult an engineering company adhering to the highest industry standards and codes.
