Hi Team
Need your small help.
In one of our project, Our Chinese customer earlier had requested for all heat exchanger materials as per ASTM . Later in detailing phase, they are asking us to provide equivalent Chinese Materials.
The oil coolers are as per API 614 . So the Tube material is ASTM B111 C44300 & Tubesheets are of ASTM B171 C46400.
Supplier is offering an alternate material as Hsn70-1AB as per GB/T8890-1998 for Tubes & tin brass Hsn62-1 as per GB/T2531-1981 for Tubesheets.
Does anyone have the GB code extract to check the materials whether they are equivalent to ASTM materials or not?
Awaiting for your reply.
Thanks
Praphulla
