GOST 12820-80 PN6-PN25 and GOST 12812-80 PN6-PN160 Flanges: Reliable solutions for various industries

GOST (Gosudarstvennyy Standart) is a set of technical standards maintained by the Russian Federation. GOST 12820-80 and GOST 12812-80 are two important standards for flanges used in various industries. Haihao Group, as a leading manufacturer and supplier of pipe fittings, provides a wide range of flanges that meet the GOST 12820-80 PN6-PN25 and GOST 12812-80 PN6-PN160 standards.

The flanges under these standards are widely used in oil and gas pipelines, power generation, chemical plants, and many other applications. The GOST 12820-80 standard covers flat and raised face flanges, while the GOST 12812-80 standard covers weld neck flanges. Both standards specify the dimensions, tolerances, materials, and testing requirements for flanges.
