Flanges are raised flat sides or flanges used to join or strengthen mechanical systems or structures, typically in machinery, piping or construction. Flanges can be bolted or welded to adjacent components to create a strong and leak-proof seal. They usually provide a way to connect hoses, valves, pumps or other mechanical components to the system. The design of the flange depends on the specific application and the forces it will withstand. Application : used for chemical industry , oil ,gas industry etc.

Uses & Applications

Forged flanges are used as a linking part to create a pipework network for cylinders, valves, pumps, and other devices. Forged flanges incorporate two different sections of the machinery. To render the entity stronger, they should be an attachment of a frame. Industrial flanges have several uses include connecting sheets, pumps, pipes and structures which explicitly need an intermediate connection point.

Flanges made of stainless steel come in several different forms. Every form satisfies its own needs. Large flanges of the welded neck are fastened to a base of the tubing. How this flange is welded guarantees that the diameter is the same as the pipe length it was attached to. Such flanges are also commonly used for usage in high-pressure applications.
