When should insulation be applied to the pressure guide pipe?
Thread Content
Was it done all at once during construction? Should we wait until insulation is needed to do it?
It is best to check the requirements specified in the design drawings of the construction project, as well as whether there are relevant clauses in the contract. It’s better to do it early than late. For reference.
The pressure lead pipe is insulated after pressure testing and anti-corrosion treatment are completed. .
It is carried out after the project has been implemented and basic debugging is completed; in fact, there is careful consideration behind each rule. Think about it carefully
Discuss it based on the specific circumstances. If the insulated area is not prone to damage during transportation and construction, there is no need to remove it again. It can be prepared in advance. But if there are looseness, leaks, or other issues during transportation or construction. It needs to be done at the end, after all the tests have been completed (air-tightness tests, strength tests, surface inspection, and acceptance, etc.).

GB50126-2008 Code for Construction of Thermal Insulation Works for Industrial Equipment and Piping – 4 Preparation and Requirements for Construction; 4.1 General Provisions; 4.1.2 The construction of thermal insulation works for industrial equipment and piping should be carried out after the pressure strength tests, tightness tests, and anti-corrosion treatments for such equipment and piping have been completed successfully. Construction codes do not exclude instrument piping in the same way that design guidelines do. Test first and then insulate; the purpose is to be able to detect and repair any leaks or poorly welded joints in a timely manner. Of course, if one really wants to go through the extra effort, the regulations don’t stop that.
Doing it now is easier than doing it when it’s necessary
