Pipeline code issue
Thread Content
May I ask?； What do C1A and P in VT7207-4''-C1A-p mean? What does 3B001 in SG7204-4''-3B001-H mean?
C1A----Material grade, same as 3B001. P------Heat insulation, personnel protection. H----Thermal insulation. Most domestic design institutes use this notation method
According to this, the first section is the medium code, the second section is the pipe size, the third section is the pipe material (the grade information is usually provided by the client), the fourth section indicates whether insulation or protection is required; additional codes such as those for heat tracing are included later on
