GB/T9948-2006 - China National Standard Petroleum Cracking Pipe
Petroleum cracking pipe manufacturing process: hot rolling, cold drawing, thermal expansion
Used in oil, refinery furnace tubes, heat exchanger tubes and pipes with seamless tubes.
The main production pipe number:
10, 20, 15CrMo, 1Cr2Mo, 1Cr5Mo, etc.
10, 20 <end rolling of hot rolled tube, normalized cold drawn tube>
15CrMo< hot rolling tube finish rolling + tempering, cold drawn tube normalizing + tempering>
1Cr2Mo< hot rolling tube finish rolling + tempering, cold drawn tube normalizing + tempering> 1Cr5Mo <annealing>
Weight formula: carbon pipe: (outer diameter - wall thickness) X wall thickness X0.02466 = KG/M
Alloy tube: (outer diameter - wall thickness) X wall thickness X0.02486 = KG/M
