Stainless Steel Flanges manufacturer

Check Stainles Steel Forged Flange Price List & Class 150 SS Flange Dimensions

We are a leading Stainless Steel Flanges manufacturer in India and we produce flanges of all sizes and types. Flanges are components that fit piping products together. They could be welded or bolted. Some flanges have sockets welded onto them for better connection and grip. Dinesh Industries has all types of flanges from all grades of metallic material. Our stainless steel flange products come in different types as well. The SS blind flange is used with stainless steel piping systems to ensure the closure of pipelines. The blind flanges could be applied permanently with welding or temporarily with bolts and nuts. The SS weld neck flange has a welded neck on it which makes the connected point stronger and allows welding to be much easier.

The SS plate flange is essentially a ring or plate that has the inner diameter matching to the outer diameter of pipe so that it is attached to the pipe for other attachments to hold together. The stainless steel slip on flange is applicable to seamless pipes as it allows the pipes to slip through precisely and be welded at the connection. The SS threaded flange has threads through which the connection is made. There are different manufacturing procedures such as the forging through which the stainles steel forged flange is manufactured. We encourage customers to inquire us with any requirements.
