Threaded flange is a kind of non welded flange, which is made of inner hole of flange into pipe thread and connected with pipe with thread. Performance characteristics of stainless steel threaded flange: 1. Due to the inner diameter of flange with thread, it can be directly used with threaded steel pipe without welding. 2. The additional pressure on pipe wall caused by threaded flange connection is small, which is one of the flange structures widely used in engineering construction. 3. The installation and disassembly of threaded flange are convenient and do not need welding.
