Stainless Steel Pipe with Flange

Flanges play a crucial role in connecting prefabricated welded stainless steel pipes. These pipes are specifically designed to establish pipe-to-flange connections, creating a secure link between different sections of the pipeline or connecting pipes to various components such as pressure vessels, valves, pumps, or integrally flanged equipment. The connection between flanges is achieved through bolts, while the attachment to the piping system can be accomplished through welding or the use of threads.
The utilization of flange connections holds immense significance in the construction of pipelines, serving as a pivotal method of connection. In fact, this method finds widespread application in industrial pipelines. Whether it is a boiler room or any production site, the presence of flanged pipes and equipment is ubiquitous.

Flanges play a crucial role in connecting pipes and facilitating the connection between pipe ends. Known as flange connection or flange joint, this mechanism involves the coupling of flanges, gaskets, and bolts to create a well-integrated sealing structure. When it comes to piping in the pipeline installation, pipe flanges are employed. These flanges possess holes that allow bolts to securely fasten two flanges together, while gaskets ensure a tight seal between them. There is a wide variety of common flanges available, such as threaded flange (PT), welded neck flange (WN), slip-on flange (SO), socket welding flange (SW), lap joint flange (LJ), and blind flange (BL).
