or end flanged fittings. Contains carbon steel material of flange, known as the
Blind flange, blind flange) [1] is also called blind flange, name is called the flange cover. Is the middle flange without hole, for sealed pipe plug. Sealing surface sort is more, in the form of a plane, convex and concave and convex surface, grooved surface, RTJ.
Forging Flange generally lower than the casting flange carbon is not easy to rust, forging good streamline, organization is compact, mechanical performance is superior to the casting flange; Improper forging technology also can appear grain big or uneven, solidification cracking phenomenon, higher than the casting flange forging cost. Forging than casting can withstand the higher shear and tensile force. Casting advantage is that can come up with more complex shape, the cost is low; Uniform forging advantage lies in the internal organization, there is no casting in porosity, inclusions and other harmful defects; From the casting production process difference between flange and forging flange, such as centrifugal flange is one of the casting flange.
