At present, there are many types of stainless steel flange products, but the basic types can be divided into the following three categories:
Integrated Stainless Steel Flanges: These stainless steel flanges are usually tapered at the neck, and are also referred to as long-neck stainless steel flanges or neck stainless steel flanges. Integrated stainless steel flanges are typically an integral part of a container or pipe.
Loose Stainless Steel Flanges: Also known as free stainless steel flanges, these flanges are loosely fitted on the flange or edge, and the bent needle stainless steel flange is not directly connected to the container or pipe. This connection method does not achieve the same strength as an integrated connection. Loose-fit stainless steel flanges are usually used in small sizes. They are widely used for storing stainless steel in non-ferrous metals (plastics, internal porcelain) that are not suitable for integrated stainless steel flanges. The inner ring of the stainless steel flange is beveled, and there is a sleeve on the pipe or other parts, which are then welded together. In general, this method is more effective than the integrated stainless steel flange, but less effective than the sleeve stainless steel flange.
Forged Flanges: Among all flange products, forged flanges have the best performance. Their raw material is usually a tube billet, which is then cut and continuously hammered to eliminate the segregation and looseness of the ingot. The price and mechanical properties are higher than those of conventional cast flanges. Stainless steel flanges are components that connect pipes, pipes to valves, and to the ends of pipes. They are used as inlet and outlet flanges of equipment, and they connect pipes to pipes. The main materials of forged flanges are carbon steel, alloy steel, and stainless steel.
