Product Description

Stainless Steel Rubber Flexible Joint Pipe Shockproof Elastic Rubber Pipe Joint


Flexible joint pipe can also be called: flexible rubber joint, rubber soft joint, soft joint, flexible rubber joint, etc. it is a pipe connector with high elasticity, high air tightness, medium resistance and weather resistance. Flexible joint pipe is a kind of composite rubber pipe which is composed of inner rubber layer, fabric reinforcement layer (the reinforcement layer has multi-layer scraped nylon cord), middle rubber layer, outer rubber layer, end reinforced metal ring or steel ring, and loose combination with metal flange or parallel joint after high temperature and high pressure vulcanization. The flexible joint pipe makes use of the advantages of rubber, such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance. It can reduce the vibration and noise of the pipeline, and compensate the thermal expansion and cold contraction caused by temperature change.


Performance characteristics of flexible joint pipe


1. The flexible joint pipe has the advantages of small volume, light weight, good elasticity and convenient installation and maintenance.

2. After installation, the flexible joint pipe can absorb the lateral, axial and angular displacement caused by the vibration of the pipeline, and is not limited by the non concentric pipeline and non parallel flange.

3. After the flexible joint pipe is installed, the noise caused by the vibration of the pipeline water pump can be reduced, and the vibration absorption ability is strong.

4. The inner seamless high pressure flexible joint pipe can effectively prevent the corrosive medium from eroding the inner wall of the rubber joint in the high temperature resistant, acid alkali resistant and oil resistant pipeline, and improve the service life.

Note: 1. The special requirements of flexible joint pipe can be customized according to user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of flexible joint pipe can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the flexible joint pipe above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the flexible joint pipe shall be installed with anti falling device.

It is very important to know the compatibility between the medium of flexible joint pipe and the selected flexible joint pipe material, the range of full temperature, full pressure and full vacuum, the required movement of flexible joint pipe, and the size between pipe flanges when selecting the appropriate flexible joint pipe. With this information, Jingning application engineers can help determine the ideal flexible joint pipe for any application.


Flexible joint pipe advantage


1. Factory price of  flexible joint pipe.

2. 16 years of manufacturing experience, 5 years of export experience.

3. Strict quality inspection, the quality far exceeds the industry standard.

4. Flexible joint pipe mold has a variety of specifications, support customization, OEM.

5. Provide free samples of flexible joint pipe.

6. Flexible joint pipe are in large stock.


Flexible joint pipe application


Flexible joint pipes are widely used in various pipeline systems, such as the connection of flexible joint pipes with pumps and valves, fire-fighting equipment and pipelines with large vibration. Pipes with frequent changes of heat and cold. It is mainly used for remote water and sewage lifting and transportation, water supply and cooling circulating water of thermal power plant, pipeline transportation of metallurgical industry, condensate water, chemical industry, cooling and dilution of petrochemical industry, and flexible connection between long and short distance pipelines in other industries. Because the flexible joint pipe has high wear resistance, it is also suitable for all industries of granular and powdery and gas low temperature.
