Domestically, GB/T 21832.1-2018 “Austenitic-ferritic duplex stainless steel welded pipes – Part 1: Heat exchange tubes” should be implemented. The finned tube heat exchange tubes of SAF 2507 are mainly produced by Otocumpe in Sweden.

The contract specifies seamless pipes, and it’s not possible to make changes
