Product Overview

Description


 


Product Description


EPDM expansion joint is a pipe joint with high elasticity, high airtightness, moderate resistance, and weather resistance. The ternary rubber expansion joint is usually made of an inner rubber layer, which can reduce pipeline vibration and noise, and compensate for thermal expansion and contraction caused by temperature changes.





Functions


1. Small size, light weight, good elasticity, and convenient installation and maintenance.


2. Absorb lateral, axial, and angular displacement caused by pipeline vibration, without being limited by non concentric pipelines and non parallel flanges.


3. Reduce the noise generated by pipeline water pump vibration and have strong vibration absorption ability.


4. Prevent corrosive media from corroding the inner wall of rubber joints in high-temperature, acid and alkali resistant, and oil resistant pipelines, and improve their service life.

Note: 1. Special requirements can be customized according to the user's drawings. The flange standard is GB / t9115.1-2000. A variety of flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. Rubber spheres can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene green rubber, fluororubber, etc.2. When the suspended water supply uses products above DN200, the pipeline must have fixed support or fixed bracket, otherwise the product should be installed with anti pull off device.

Do you know how is a high quality rubber expansion joint made?Let's see with JINGNING.


It is very important to select the appropriate flexible rubber expansion joint of the pipeline, understand the compatibility of the medium with the selected material, the full temperature, pressure and vacuum range, the required movement and the size between the pipeline flanges.
