Plate slip on flange (chemical standard HG20592, national standards gb/t9119, Machinery jb/t81): Easy to draw, simple to manufacture, low cost, wide use, but the rigidity is not good, so it can not be used for supply and demand, flammable, explosive and higher vacuum requirements of the chemical process piping system and high, extremely hazardous occasions. The sealing type has a plane and a sudden face.
Plate slip on flange is the most common flange, the pressure is PN0. PN0.6, PN1.0, PN1.6, PN2.5.
Welding form: Plate slip on flange is the pipe inserted into the flange to weld.
Material of slip on flange: $number, $number. $number. 316L. 0cr18ni9.321.202, Carbon Steel, $number, 20G, and alloy steel, etc.
The form of the sealing surface of the stainless steel slip on flange has several categories:
Bump Face (MFM) dn1300~3000 dn300~3000 dn400~2000 dn300~800
Tenon Groove surface (TG) dn1300~3000 dn300~3000 dn300~3000 dn300~800
Full plane (FF) dn300~3000 dn300~3000 dn300~3000 dn300~800
Because plate slip on flange has a good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, heavy industry, refrigeration, sanitation, plumbing, fire, electricity, aerospace, shipbuilding and other basic projects.
