Pipes in the PID diagram
Thread Content
What do the letters on the pipes in the PID diagram represent? 500-p-310102-B2-3T-T. I want to know what B2 means. What do B3H.K1. mean as well? Regarding what materials such letters are made of.
What does B2 mean? B stands for the pipe material, and 2 represents the pressure rating. Looking at the PID symbol table specifically, the pipe class symbols vary depending on the design drawings.
The last one was a mistake. 500-P-310102-B2-3F-T
B represents the pressure rating, and 2 represents the corrosion allowance
Please refer to the PID homepage or consult the PID provider
Each PID is preceded by a description of the relevant symbols; different companies follow different standards, which generally include details such as pipe diameter, medium, material, requirements regarding corrosion and insulation performance, and pipeline numbers
Look at the legend; it usually appears normally
