titanium flange application
Mainly used in petrochemical, medical and health, power, aerospace, military, fire protection, metallurgy, shipbuilding, gas,
and Environmental protection requires high pressure.
titanium flanges function
The flange, gasket and bolt are connected to each other as a detachable connection of a group of combined sealing structures.
Flange connection is an important connection method for pipeline construction.
The flange connection is easy to use and can withstand large pressures.
