Flat welded plate flange

Flat Forged Plate Flange (chemical standard hg20592, national standard GB / t9119, mechanical JB / T81): it is easy to obtain materials, simple to manufacture, low cost and widely used; However, the rigidity is poor, so it shall not be used in the chemical process piping system with requirements of supply and demand, flammability, explosion and high vacuum degree and the occasions with high and extreme hazards. The sealing surface type has plane and convex surface.

After years of continuous research and development and improvement,Durable Forged Steel Flange series sealing materials are suitable for a wide range of application conditions. Durable dragon products are widely used in oil refining, petrochemical, chemical, electric power (thermal and nuclear power), paper making, food, medicine and other end users and their corresponding equipment manufacturing, engineering design and construction.  The temperature range of durable dragon materials is from-268℃ at low temperature to 1000℃ at high temperature, and the pressure is from vacuum condition to 2500 pounds in American standard. Durable dragon products can safely and reliably seal various high-risk media such as liquid oxygen, phosgene, hydrofluoric acid and so on. In the air separation industry, Durable Dragon products and oxygen cleaning process have the gasket oxygen cleaning deoiling and degreasing technology %E which has been verified by users in various industries.You can safely use our Flange Gasket .
