Flanges Manufacturer In India

Connections made with a industrial flanges help in efficiently connecting a pipe, tube, valve, and other equipment to form a pipeline system. The ASME B16.5 Flange covers equipment that covers standard pressure ratings, materials, and tolerances that are suited to work in different pressure and temperature conditions. Each country has its own flanges that have unique features. The Korean flanges provide easy access for cleaning and inspection, allowing room for modification. These flanges can be either welded or screwed. A French can be produced in iron, aluminum, brass, bronze, stainless steel, plate, and forged carbon steel material.

We are the Flanges Manufacturer In India who have a vast inventory of products that are available in different sizes and shapes that are suited to meet all customer requirements. The industrial pipe flanges are disc-shaped flanges that are used to measure the flow of fluids and gases. These pipe steel flanges are designed possessing a raised face, flat face, and ring-type joint facing. These pipe weld flanges act as blanks to terminate the flow of pressurized media across harsh environments. The branch connection on the module has a welding section with the other being a flange connection. The rating of these flanges is in class 150 to 2500.
