[MW:8322] Chinese Materials

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
