GOST 12820 AND GOST 12821 FLAT AND WELD NACK 16MN FORGED STEEL FLANGE
The characteristics of the GOST standard flange:
High impact: because of the unique function of the impact strength than other solid wall pipe have increased significantly improved, the ring stiffness of proportion in the solid wall of 1.3 times.
Long service life: pipe under rated using the environment temperature and pressure, service life can reach more than 50 years, has a UV protection, radiation protection performance.
Good corrosion resistance: except a handful of hydrogenated agent, can withstand the corrosion of various chemical medium, flange has good acid and alkali resistance, corrosion resistance, no rust, no corrosion and electrochemical corrosion performance.
Good heat preservation:because the material coefficient of thermal conductivity is low, the coefficient of thermal conductivity of 20 degrees Celsius 0.21 0.24 W/mk, than steel pipe (43 to 52 W/mk), purple steel pipe (333 W/mk), so the heat preservation is good.
