The role of stainless steel flange liner

The improved structure has the following advantages: the working medium of the equipment does not directly contact the welding seam of the liner flange, thus avoiding the corrosion of the welding seam by the medium. Second, even if a small amount of medium is in contact with the welding seam, due to the finishing of the welding seam on the sealing surface of the lining ring of the stainless steel lining flange, the surface is smooth and it is not easy to deposit media and impurities, which makes the welding seam and the heat affected zone corrod The rate is greatly reduced, thereby extending the life of the equipment.

The carbon steel flange is not directly welded to the stainless steel cylinder, which prevents the carburization of the flange to the cylinder, thereby avoiding the possibility of accelerating the corrosion of the stainless steel cylinder due to the increase in carbon content. Fourth, the flange deformation after welding is small, and the flange thickness can be obtained after finishing. The lining ring of the stainless steel flange plays an important role in the tightness of the cylinder, which can alleviate the welding obstacles of the carbon steel flange and the stainless steel flange, and is convenient for installation and flange leakage repair.
