Regarding heat preservation and tracing
Thread Content
For process pipelines and instrument pressure tapping lines, under what conditions is insulation required, and under what conditions is heating necessary?
Regarding your question: 1. As for the conditions under which insulation is required, it is recommended that you refer to Clause 3.0.1 of the \"GB 50264-2013 Code for Design of Thermal Insulation of Industrial Equipment and Piping\". 2. Regarding the conditions under which heating is necessary, it is suggested that you consult Clause 5.1 on the scope of heating in the \"SHT 3040-2012 Code for Design of Heating Traces and Jacketed Piping in Petrochemical Industries\". These guidelines are provided for your reference
The second floor has been explained in great detail already.
In general engineering, there are specifications for the thermal insulation of equipment and pipelines, which provide detailed requirements based on specific operating conditions. The process engineering team will clearly indicate on the piping diagram which pipes are insulated and which are not. Also, specify the type of insulation (such as heat retention, scald protection, freeze protection, cold preservation, etc.). You just need to follow these steps for the construction.
