Interpretation of pipeline numbers
Thread Content
Pipe number: 2``— C4—39—B1A1—N 2`` ***** Pipe diameter C4 ***** Medium transported 39 ***** Pipe code B1A1 ***** ? ? ? ? What does N ***** represent? ? ? ? What does it represent?
Is B1A1 the pressure rating code for pipes?
The pipe material grade code N denotes insulation requirements
B1A1 is the code for pipeline material grade; it may vary depending on the individual engineering company or project, and is determined by the design specifications. This grade could be carbon steel, CL150, with a corrosion allowance of 1.5 mm.
B1A1 is a pipeline material grade; check the company’s regulations regarding pipeline material grades, as this information is usually specified there. Piping grades generally include material, corrosion allowance, and pressure rating. N might be the adiabatic form. This code also depends on the company’s uniform insulation regulations.
This depends on the legend description on the first page of the piping layout diagram; different design firms use different symbols for the legends! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
The pipe material grade code N indicates insulation requirements; no insulation is required
B1A1 is a pipeline material grade; check the company’s regulations regarding pipeline material grades, as this information is usually specified there. Piping grades generally include material, corrosion allowance, and pressure rating. Does N have insulation?
B1A1 pipe material； Is heat treatment required for N?
