The JIS B2220 Slip on Plate Flange is flanged on the pipe end by using a flange, a steel ring, etc., so that the flange can move on the pipe end. Steel rings or flanges are the sealing faces, and the flanges act to compress them. It can be seen that the loose flange is not in contact with the medium due to being blocked by the steel ring or the flange. It is suitable for the connection and corrosion-resistant pipelines of non-ferrous metals such as steel and aluminum and stainless acid-resistant steel containers.
This slip on plate flange is the same as a flat-welded flange. It is also a flange that extends steel pipes, pipe fittings, etc. into the flange and is connected to the equipment or piping through fillet welds.
1. JIS B2220 Slip on Plate Flange is suitable for a wide range. Its advantage is that the flange welding assembly is easier to center, and the price is relatively cheap, so it has been widely used.
2. It has the characteristics of non-rigid connection, detachable and tensile strength. The flange connection method is usually used as a detachable connection on the low pressure transfer line.
3. It uses certain welding standards and technology to produce and process, in line with the corresponding production standards and requirements of the country.
4. The butt weld of the ring is subjected to post-weld heat treatment, and 100% ray or ultrasonic flaw detection, and the radiographic inspection meets the Class II requirements of JB4730, and the ultrasonic flaw detection meets the Class I requirements of JB4730.
