What is the national implementation standard for titanium alloy flanges?

There are many national implementation standards and related industry standards for titanium alloy flanges. In addition to the standards mentioned above, there are also GB/T 25198-2023, GB/T 25137-2010, etc., as follows:
GB/T 9112-2010: It specifies the types and parameters of steel pipe flanges. Although it is mainly aimed at steel flanges, some clauses are also applicable to titanium alloy flanges. It standardizes the connection dimensions, pressure grades and other parameters of titanium alloy flanges, and provides a dimensional basis for the connection between titanium alloy flanges and other pipeline components.
GB/T 16598-2013: It is the material performance standard for titanium and titanium alloy flanges, which clarifies the mechanical properties, physical properties and chemical composition requirements that titanium alloys should have when used in flanges, ensuring that titanium alloy flanges can operate safely and reliably under different working conditions.

GB/T 25137-2010: It stipulates the size, shape, technical requirements, test methods, etc. of titanium and titanium alloy cakes and rings. If titanium alloy flanges use cakes or rings as blanks, they must comply with the relevant requirements of this standard, which plays an important role in ensuring the quality of flange blanks.
GB/T 25198-2023:It belongs to the pressure vessel flange standard and stipulates the design, manufacturing, inspection and other aspects of titanium alloy pressure vessel flanges to ensure their sealing, strength and safety when used in pressure vessels.

NB/T 47023-2012:It is the standard for titanium butt-weld flanges, which provides detailed provisions on the structural form, size specifications, technical requirements, inspection and test methods of titanium butt-weld flanges, which helps to standardize the production and application of titanium butt-weld flanges.
HG/T 20592-2009:The flange standard for the chemical industry includes the marking method, size specifications, technical requirements, etc. of titanium alloy flanges. It is widely used in the design, procurement and installation of titanium alloy flanges in the chemical industry.

JB/T 82-2015: Technical specifications for flanges in the machinery industry put forward requirements for the manufacturing process, inspection requirements, acceptance rules, etc. of titanium alloy flanges. They are applicable to titanium alloy flanges in the machinery manufacturing field and ensure their applicability and reliability in mechanical equipment.
