STAINLESS STEEL FLANGES

STAINLESS STEEL FLANGES

Various stainless steel materials are used to make stainless steel flanges. The composition of the material determines the grade of stainless steel, and its mechanical qualities also differ. An industry leader in the production and distribution of these flanges is Rameshwar Metal. These ASTM A182 Weld Neck Flanges are composed of a low-carbon super austenitic material that has good corrosion resistance. The utility scrubber assembly are among the uses. The flanges ability to withstand corrosion makes them useful in fertilizer and acid production facilities.

In these sectors, a pipeline is closed using a stainless steel pipe flange. For ease of maintenance and removal, the blind flange can be bolted temporarily or permanently fastened with welding. These flanges are available in nominal bore sizes ranging from ½ inches to 48 inches. Additionally, there are other varieties that fall under various pressure classes, such as the SS Blind Flange Dimension. Pressure classes range from PN6 to PN64 and 150 to 2500. These show the highest pressure that each flange can sustain when in use.

Welded neck raised face flanges are what the SS flanges are. These flanges are supported by the welded neck, which keeps the pipes in place during the welding process. Maximum attachment for welding or room for bolts and nuts is made possible by the elevated face. Flanges come in a variety of brands and specifications, such as the stainless steel threaded pipe flange, which is renowned for its quality, strength, and resistance to corrosion. We provide a wide range of stainless steel flanges in various diameters, standards, and requirements. For further details on the SS Slip On Flanges and their costs, please get in touch with us. We are one of India’s top manufacturers of stainless steel flanges.
