Blind Plate Flange
Blind Plate Flange Manufacturer
Blind Plate Flanges can carry out superior stress from inner pressure and bolt loading from the time when the supreme stresses in the Blind Plate Flanges are meandering stresses at the centre.
These Flanges are used to outright off the finishes of valves, piping and pressure vessel preambles.
Our flanges are supplied through appropriate test certificates of finished products and standard raw materials.
A Blind Plate Flanges is a cast ring or forged of steel designed to connect mechanically two sections of steel pipe or join pipe to a pressure pump, vessel, valve or any other piece of equipment.
Same standard flanges can either be flat face or raised face.
