A rubber soft joint is a pipe fitting that connects two pipes, and is generally used to eliminate vibration, noise, and vibration during pipeline operation. It is made of rubber and metal materials, and plays the role of cushioning, sound insulation and vibration absorption in the pipeline.
Next, we can discuss the manufacturing process of rubber soft joints. The manufacture of rubber soft joints requires the use of high-pressure molding machines to process rubber and metal materials under high temperature and high pressure to produce rubber soft joints with elasticity and tensile properties.
In addition, we can also learn about the application of rubber soft joints. Rubber soft joints are widely used in petrochemical, water treatment, HVAC, construction and installation industries. In these fields, rubber soft joints can ensure the normal operation of the pipeline system, reduce noise and vibration, and improve safety and reliability.
Flexible rubber soft joints have been widely used and promoted in different fields and industries, and then two semicircular bending parts are assembled and welded. The welding of flexible rubber soft joints needs to be produced and processed according to the process, and has been applied and promoted to varying degrees. Materials used for flexible rubber joints, in general, the higher the carbon content of flexible rubber joints, the greater the hardness, the higher the strength, but the lower the plasticity. It mainly refers to that the mechanical properties depend on the carbon content in the steel, generally a large amount of steel alloying elements, sometimes called ordinary carbon steel or carbon steel.
When the weld metal is at high temperature, it is too late to discharge when the molten pool is cooled and solidified, and pores are formed inside or on the surface of the weld, which are pores, which absorb too much gas or gas generated by the metallurgical reaction inside the molten pool. The existence of pores reduces the effective working section of the weld and reduces the mechanical strength of the joint. If there are penetrating or continuous pores, it will seriously affect the tightness of the weldment. Non-metallic slag is contained in the weld, which is called slag inclusion. The slag inclusion reduces the working section of the weld, causes stress concentration, and reduces the strength and impact toughness of the weld.
