Introduction: The flexible rubber joint is composed of rubber elasticity, high sealing, medium inductive load, aging resistance and radiation resistance. It is made of high strength, stable hot and cold polyester cord fabric, vulcanized rubber by high pressure and high temperature abrasive tools. Large flange rubber flexible rubber joint general

flexibility Rubber joint It is composed of rubber, high resistance to radiation aging and high load resistance. It is made of high strength, stable hot and cold polyester cord fabric, vulcanized rubber by high pressure and high temperature abrasive tools. Large flange rubber flexible joint is generally installed in hot water pipe, steam, flue gas, air, gas, etc. The use of heat caused by the deformation of the tube. Limited flexible rubber joint is a kind of fabric reinforced rubber parts and plane movable joint, which is used to reduce pipeline vibration, noise, flexibility and convenience. According to the advantages of this kind of flexible rubber joint, it has been widely used, so its installation and maintenance are very important. Next, we will learn how to operate in detail.
Service life of flexible rubber joint:
I. during the construction and installation of flexible rubber joint pipes, it is necessary to maintain the natural conditions, and it is not allowed to deform the products during the installation. That can prevent the early damage of the product and reduce the effect of use.
2. When installing and using large diameter flexible rubber joint, in order to facilitate installation and reduce labor intensity, a short pipe with appropriate length should be made at one end of the flange. After the rubber joint is connected with the short pipe at the other end, the short pipe at the other end is welded with the long pipe
3. In order to facilitate the axial error caused by short pipe welding deformation, the pipe flanges on both sides shall be temporarily welded with round steel or other metal blocks with corresponding strength before welding, so as to produce rigid body at the joint of rubber joint and flange. After the welding of the short pipe is finished, the welding object should be removed to make the rubber joint in natural condition after installation.
If there is a multi-layer support, it is necessary to set up a bracket near the product's high tension or pressure limit, or fix it at the inlet and outlet of the product.
5. When the limit flexible rubber joint is connected with the pipe flange, the screw of the bolt shall be extended to one end of the pipe flange, so as to avoid the rubber joint from being squeezed or punctured when the thread is subject to stress expansion. The bolts on both sides must be clamped symmetrically to ensure that all bolts are tightened uniformly. In the area where standard deviation is used, spring washer should be added in addition to flat pad to avoid nut loosening and ensure the service life of flanging rubber flexible rubber joint.
In the process of construction and installation of flexible rubber joint pipe, it is necessary to maintain the natural condition, and it is not allowed to deform the product during the installation process. When installing and using large diameter flexible rubber joint, in order to facilitate installation and reduce labor intensity, a short pipe with appropriate length should be made at one end of the flange. When the screw joint is connected to the rubber pipe, the screw joint shall be limited by the screw thread or the rubber pipe joint.
