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.
