  Flat welding flange standards shall apply

  Flat welding flange is suitable for the nominal pressure of not more than 2.5 MPa carbon steel pipe connection, flat welding flange sealing surface can be made into smooth type, concave and convex type and mortise type 3 kinds. Smooth and flat welding flange are the largest. In the condition of medium is more moderate cases, such as suit low circulating water, the purification of compressed air, and it has the advantage of the price is cheaper; Butt welding steel flange: suit for flange and pipe welding, its structure is reasonable, the strength and stiffness is bigger, can withstand high temperature and high pressure curve and temperature fluctuation, and repeated the sealing is reliable. Nominal pressure of 0.25 ~ 2.5 MPa butt welding flange with concave and convex type sealing surface.

  We have adopted advanced production equipment and technologies to manufacture our blind flanges and forged fitting,which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
