Flange of Rotary Drilling Hose

                                                                 High Pressure Flange

The high pressure flange is forged from high strength alloy steel with imported advanced technology in the world. Strict heat treatment ensures uniform metallographic structure and bearing capacity. It is widely used in the petroleum and chemical industry, boilers and pressure vessels, ships and other sectors for high pressure connection.
