Stainless steel threaded flange also known as: threaded flange and threaded flange, refers to the use of thread and pipe connection of a flange; the advantage is that welding is not required, the commonly used carbon steel materials include: 304, 304L, 316, 316L, 321 and other stainless steel flange materials; commonly used sealing surface types: raised face (RF) and full face (FF); for easy installation, in water supply, drainage and other work It has been widely used.
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. Production standards: American Standard, German standard, European standard, British standard, Japanese standard and South African standard

Stainless steel threaded flange can be divided into: (304, 304L, 316, 316L, S30408, S30403, S31608, S31603, SUS304, 0Cr18Ni9, 00Cr19Ni10, etc.)
The stainless steel thread flange is connected with the pipe wall through the thread, and the additional pressure on the pipe wall is small. It is one of the flange structures widely used in engineering construction. It has the advantages of convenient installation on site and no welding. The sealing surface type has convex surface and plane.
