What is clamp rubber joint


clamp rubber joint also named clamp type flexible rubber joint,rubber expansion joints, clamp type flexible rubber expansion joint, no hub coupling, flexible pipe connectors and flexible hose coupling.


Clamp rubber joints use clamps instead of flanges and bolts. When in use, the two ends of the clamp rubber joints can be conveniently placed on the pipe to be connected, and the rubber joint is fixedly connected to the pipe through the stainless steel clamp; disassembly; Just loosen the clamp at the time. The clamp rubber joint reduces vibration, reduces noise, has good flexibility and is easy to use. High internal density and good elastic deformation effect. The clamp rubber joint is composed of fabric-reinforced rubber parts and clamp fasteners, which are used for pipe shock absorption, noise reduction, and displacement compensation joints. It is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance.



Features of clamp rubber joint


The clamp-type flexible rubber soft joint saves flanges and bolts and saves engineering expenses.


The clamp-type flexible rubber soft joint does not need flanging at the nozzle, which simplifies the production process of the rubber joint and saves raw materials. The clamp-type flexible rubber soft joint simplifies the installation and maintenance work and improves the work rate.


The clamp rubber joint reduces vibration, reduces noise, has good flexibility and is easy to use. High internal density and good elastic deformation effect.


The clamp rubber joint is composed of fabric-reinforced rubber parts and clamp fasteners, which are used for pipe vibration isolation, noise reduction, and displacement compensation joints.


Just loosen the clamp when dismounting.


Compensate pipeline displacement which is caused by thermal expansion and water delivery.


Rubber layer protect rubber joint from being damaged and corroded by external environmental.



It is a pipe joint with elasticity, high air tightness, medium resistance and weather resistance. So as to achieve the purpose of compensating the displacement of the pipeline due to thermal expansion and contraction, and water delivery.


The clamp is made of stainless steel and has the characteristics of corrosion resistance. It has good comprehensive performance, mainly used for the lifting and transportation of raw water and sewage, the water supply and circulating water of thermal power plants, the pipeline transportation of chemical substances in the metallurgical industry, condensate water, the chemical industry, the petrochemical industry, dilution and other industries. Flexible connection between distance pipelines.


Flexible hose coupling


Application of clamp rubber joint


Applied to low-temperature heating system, it must meet the technical requirements of pipeline expansion, support setting, rubber heat resistance and performance. It is used for fire fighting system, domestic water supply system, hot water system, air conditioning system, etc.; because the clamp connection form can be well applied in pipeline maintenance and construction, it provides convenience for maintenance operations. Natural rubber is suitable for water at room temperature, below 70 degrees, without corrosive media. Stainless steel clamp-type flexible rubber soft joints use clamps instead of flanges and bolts. When in use, it is convenient to put the two ends of the clamp-type rubber joints on the pipe to be connected, and connect the rubber joints with the stainless steel clamps. The pipeline is fixedly connected; just loosen the clamp when disassembling. The clamp-type rubber joint reduces vibration, reduces noise, has good flexibility and is easy to use. High internal density and good elastic deformation.


The stainless steel clamp type flexible rubber soft joint is developed on the basis of the original rubber joint product production. It can be used in the occasions with a small pressure level. It can play a good role in connecting the pipeline, which is convenient for users to install and use. The new clamp-type connection method can reduce the hidden dangers and problems caused by the connection problem, which is convenient for users to a large extent, and also reduces the purchase cost of the product, which satisfies the use of the project. demand. The stainless steel clamp type flexible rubber soft joint has no problem whether it is the size of the caliber or what kind of special medium is required for conveying.


Precautions for installation of clamp rubber joints


1. During the pipeline construction and installation, the clamp rubber joint should be in a natural state. Do not artificially deform the product during installation, so as to avoid the early damage of the product and the weakening of the use effect. If the product is designed to be installed at the proximal end of the pump outlet or the corner of the pipe, and high pressure, high-rise buildings are suspended, and the product is used vertically, the pipe has a specified bracket or fixed bracket, hanger, etc., fixed support and fixation The force of the bracket and hanger is greater than the axial force, otherwise the product should be equipped with a pull-off limit device.


2. When the clamp rubber joint is installed, the reinforcement rings at both ends of the sphere must be clamped into the flange groove to prevent the sphere and flange from pulling apart when the pipeline is under pressure. When installing the bolts, first tighten the symmetrical bolts to ensure that all the spheres and flanges are in place. When the rubber joint of the clamp is connected to the pipe flange, the screw rod of the bolt should extend to one end of the pipe flange to prevent the thread from being compressed and expanded. The arched part of the joint is squeezed or punctured, and the bolts at each end are symmetrically tightened to make all bolts tight. In places with harsh conditions, in addition to flat washers, spring washers should be added to prevent loosening of the nuts.


3. When the clamp rubber joint is used under the condition of close distance or frequent start and stop of the pump outlet, in order to reduce the impact of excessive stretching and compression of the clamp rubber joint length on the pump and pipeline, it should be installed on the flanges. Increase the limit device at the end. When installing and using large-caliber flexible rubber joints, in order to facilitate installation and reduce labor intensity, a short pipe of appropriate length should be made at one end of the flange. After the rubber clamp joint is connected to the short pipe and the other end of the pipe, then Connect the short tube with the long tube at the opposite end.


4. In order to facilitate the radial deviation caused by the deformation of the short pipe, round steel or other metal objects of corresponding strength should be used in front of the pipe flanges at both ends to form a rigid body at the joint of the flexible clamp and the flange. After the short pipe is completed, remove the objects again so that the rubber joint is in a natural state after installation.
