Heated pipeline
Thread Content
What are the requirements for insulation of heat-traced pipes? (Electrical heating, steam heating, hot water heating) When is it necessary to use electrical heating, steam heating, or hot water heating? How is the thickness of the heating pipes calculated? What are the differences between (electrical heating, steam heating, hot water heating) and the insulation and thickness calculations for ordinary steam pipes?
It is generally determined based on the material that requires heating, and in practice, the distinction isn’t very clear. Try to use hot water for heating.
Is it not very clear in practice either? I just want to understand it clearly
Look for SH 3126-2001 in the forum’s resource sharing section； SH3040-2002T Code for Design of Pipeline Accompanying Pipes and Jacketed Pipes in Petrochemical Industries ； GB8174-87 Testing and Evaluation of Thermal Insulation Performance of Equipment and Pipelines ； SHS 01033-2004 Procedures for the maintenance and repair of insulation and cooling systems for equipment and pipelines. There are some relatively detailed regulatory requirements here
Currently, there are no specific design specifications for electric heat tracing in China; only some guidelines regarding electric heat tracing can be found in the \"Design Specifications for Heating and Insulation of Instruments and Pipelines in the Petrochemical Industry\" SH-3126-2001. However, such specifications have not yet been applied to long-distance pipelines and industrial pipelines.
