Which standard is used for bolts on flanges?

Reply #22016-11-16

It mainly depends on what standard the flange follows: flanges that meet GB standards are paired with bolts that also conform to GB standards, while flanges of the HG standard are paired with bolts of the HG standard. Essentially, it’s necessary to determine the specifications and length of the flange bolts, and then select bolts that meet the required strength and material standards. These are generally applicable throughout China

It is specified in the HG20592 standard

See 20592: Different bolts, different standards

It mainly depends on what standards apply to the flange; whatever standards are relevant to the flange are the ones that will be used as well
