Do you know what range of flat welding JIS flanges can be used?
1. Flat welding flange is a kind of pipe fitting. Refers to the flange with the neck and the pipe transition section, as well as the butt welding connection with the pipe. The butt welding flange is not easy to deform, has good sealing performance and is widely used. With corresponding rigidity and elasticity requirements, butt welding thinning transition is reasonable. The distance between the welding seam and the joint surface is large, and the joint surface has no welding temperature deformation.
2. The flat welding flange is not easy to deform, has good sealing performance and is widely used. With corresponding rigidity and elasticity requirements, butt welding thinning transition is reasonable. The distance between the welding seam and the joint surface is large, and the joint surface has no welding temperature deformation. A relatively complex cough horn structure is adopted. Suitable for pipelines with large pressure and temperature fluctuations or high temperature, high temperature and low temperature pipelines. Generally used for pipelines with PN greater than 2.5 MPa. Connection of pipelines and valves; also used to transport expensive, flammable and explosive media pipelines.
Flat welding flange features: flat welding flanges can save space and reduce weight during use. The most important thing is to ensure that the head position does not leak. They have good sealing performance. The reason for the reduced size of the compact flange is that the diameter of the seal is reduced, which decreases the cross-section of the sealing surface. Additionally, the flange gasket has been replaced by a sealing ring to ensure the matching of the sealing surface. To compact the cover, only a small amount of pressure is required. As the required pressure decreases, the size and number of bolts decrease accordingly. Finally, a new product with small size and light weight was designed.
High-pressure flanges are mainly used for pipeline installation. High-pressure flange connection is an important connection method in pipeline construction. It plays a very important role and value in the connection of pipelines. The connection of high-pressure wires is to fix two pipes, pipes, or equipment. First, fix it on a flange, add flange pads between the two flanges, and fix them together with bolts to complete the connection. Some pipe fittings and equipment have their own flange, which is also a type of flange connection.
High-pressure flange products have wear resistance. Ceramic composite steel pipe: The Al2O3 content in the ceramic lining is more than 95%, the microhardness is HV1000-1500, and the wear resistance is high. The wear resistance is about 10 times that of quenched carbon steel, which is better than tungsten carbide.
