GB/T 3091-2015
AbolishedWelded steel pipes for low pressure liquid delivery
低压流体输送用焊接钢管
Application Summary AI generated
This standard specifies the dimensions, technical requirements, test methods, and inspection rules for welded steel pipes used in low-pressure liquid delivery systems. It is primarily applied in industries such as water supply, drainage, gas, heating, and fire protection for transporting water, air, steam, or other non-corrosive fluids at pressures typically below 2.5 MPa. The standard ensures pipe quality and safety in construction, municipal engineering, and general industrial piping applications.
