May I ask if GB6479 can be applied to GC1 pipes? Thank you
Tubes that comply with the GB6479 standard can be used in pressure vessels for special equipment, and they are certainly suitable for use in pipelines as well.
However, according to Article 26 of TSG_D0001-2009 _Code for Safety Inspection of Pressure Piping – Industrial Piping_, carbon structural steel shall not be used in GCI-class piping
6479 9948 5310 are all acceptable
High-pressure seamless steel tubes for fertilizer equipment (GB6479-2013) are high-quality carbon structural steel and alloy steel seamless tubes suitable for use in chemical equipment and pipelines operating at temperatures ranging from -40 to 400°C and under pressures of 10 to 30 Ma. GB6479 steel pipes are mainly used as seamless steel pipes for high-pressure fertilizer equipment and pipelines. Its representative materials are 20# and Q345B grade steel
