Frequently asked questions
What is the difference between ASME and ASTM standards?
ASTM writes material specifications (e.g. A106, A182); ASME writes design codes and dimensional standards (e.g. B31.3, B16.5) and adopts ASTM specs as SA/SB specifications.
What is GB/T?
GB/T is a recommended Chinese national standard; GB without /T is mandatory. HG/T and NB/T are Chinese chemical- and energy-industry standards.
What is the Indian standard for steel pipe flanges?
IS 6392.
