Flexible Rubber joint How to use applicable flange is related to the performance of rubber joint. Stainless steel bolt is not necessary for rubber joint flange. Stainless steel bolt is used to facilitate disassembly and assembly (carbon steel is easy to rust). It can also be used in some special occasions where hot work is not allowed or other special occasions.
In this session of the flange continued to rise a variety of new products, in the steel pipe industry is also the same continuous development to create high-grade products to sell steel pipes, indeed, the flange is also in the steel industry to slowly develop, flange blank is also in the production of flange, flange plate left in the rough parts, however, these flange steel parts left on the manufacturing flange Hair embryo. Flange neck butt welding, neck flat welding, socket welding and external thread flange are generally made of steel casting or forging and rolling process. Flange refers to the connection equipment of two large diameter pipelines, which is generally composed of two flange plates and several tightening anchor bolts. The flange is made of alloy steel. Low carbon steel has good plastic deformation and low compressive strength. It will become more and more hard after adding appropriate amount of carbon element, and the plastic deformation is reduced and the compressive strength is improved. Flange connection may need to bear very regulator tension, compressive strength, torsion, tensile strength, flange is a good choice. Post weld heat treatment shall be carried out for butt weld of ring diagram, and radiographic or ultrasonic flaw detector shall be prepared. The ultrasonic flaw detector shall meet the requirements of class I in JB4730. When thick steel plate or channel steel is selected for manufacturing, the following requirements must be met:
1. The thick steel plate shall pass through the ultrasonic flaw detector without layer defect.
2. The steel should be cut into strips along the cold rolling direction, rolled and butt welded to form a ring, and the surface of the steel will produce a cylindrical surface of the ring. It is not allowed to select steel plate to machine directly into flange with neck.
3. Full penetration weld shall be used for butt weld of ring. When carbon steel bolt is selected, it is not necessary to add insulating gasket and sleeve barrel. In addition, insulating gasket and sleeve barrel are only used for occasions that are likely to be charged or the fluid in the pipeline is flammable and explosive. When stainless steel bolts are used in such places, insulating gasket and sleeve barrel shall also be added.
   Flexible rubber joint Performance features:
1. The flexible rubber joint can greatly reduce the vibration and noise of the pipeline system, and fundamentally deal with the problems of socket offset, axial expansion and different centrality of various pipelines.
2. According to different raw materials, the flexible single ball rubber joint can be made into various kinds of acid resistance, alkali resistance, corrosion resistance, acid and alkali resistance, high temperature resistance, etc., which can be integrated into a variety of materials and natural environment.
3. The raw material of flexible rubber joint is rubber, with good sealing performance, light weight, convenient installation and maintenance, and long service life. However, it is prevented from contacting with sharp metal materials and equipment to prevent the ball from being punctured.
4. If the flexible rubber joint is empty, it should be equipped with extensible support frame, and the bolts should be tightened by the top angle method during installation.
5. If the working pressure of flexible rubber joint pipe is too high, use bolts to connect the flanges on both sides.
