Stainless steel flange has good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, oil, medical machinery manufacturing. Because stainless steel has good corrosion resistance, it allows the structural parts to permanently maintain the integrity of the engineering design. Chromium-containing stainless steel flanges also set the mechanical strength and high elongation in one, easy to manufacture parts.
Another stainless steel flange should be ultrasonic flaw detection, no stratification defects; should be cut along the direction of steel rolling into a strip, the bending of the ring into a ring, and the steel surface to form a ring cylinder. The ring butt welds should be fully welded through the weld; ring butt welds should be post-weld heat treatment, and for 100% ray or ultrasonic testing, and ray detection in line with JB4730 Class II requirements, ultrasonic testing in line with JB4730 Class I requirements.
When people are building, they often use a lot of different materials, especially the use of stainless steel materials, for people in the production of a variety of products and equipment to bring more convenience. One of the stainless steel flange is mainly used for pipe connections, for the pipeline to bring more convenience. Before using stainless steel flanges, the installation is a very important process, there are many details that need our attention.
1, stainless steel flange in the fastening, its tightening force should be consistent direction, and the compression of the pad should also be controlled in about one-third.
2, stainless steel flange in the installation process should be to keep the sealing surface of the flat and clean, if found to have oil or rust when they need to clean them, to prevent the impact of stainless steel flange sealing performance.
Stainless steel flanges are a kind of disc-shaped part, the most common in pipeline engineering. It is often used in piping engineering such as pipe and pipe connection or pipe and pipe connection. It is widely used in petroleum, chemical, nuclear power plant, food manufacturing, construction, shipbuilding, papermaking and medical industry.
Stainless steel flanges can also be called a flange or flange, etc., in the pipeline connection, the stainless steel flange plays an important role in the connection between the use of the flange to seal the flange, so the flange, Sealing performance is good.
Stainless steel flanges are very convenient and rapid during installation and disassembly. Therefore, there is a very good application for piping replacement or disassembly inspection piping conditions, resulting in better sealing performance.
