Product Description

SS 304 Flange EPDM Rubber Expansion Joint  For Pipeline


The rubber expansion joint is composed of inner layer and outer layer of rubber, cord layer and wire ring. After vulcanization, it is combined with metal flange or parallel joint. Rubber expansion joint can reduce vibration and noise, and can compensate the thermal expansion and contraction caused by temperature changes. Rubber expansion joints have been widely used in various pipeline systems.According to different media, the rubber materials used in rubber expansion joints are also different, including NR, SBR, IIR, NBR, EPDM, Cr, fkr, etc. It has heat resistance, acid resistance, alkali resistance, corrosion resistance and oil resistance.


Performance characteristics of rubber expansion joint


1. The decompression effect of rubber expansion joint is reliable, and the outlet pressure is not affected by the inlet pressure and flow rate. It can reduce both dynamic pressure and static pressure, and keep the set outlet pressure constant

2. The rubber expansion joint is easy to adjust and operate. Just adjust the adjusting screw of the pilot rubber joint to obtain accurate and stable outlet pressure

3. The rubber expansion joint has good energy saving effect. The rubber joint body adopts full channel streamline DC design, with small pressure loss, large flow, small volume and light weight

4. The rubber expansion joint has a long service life, and the important parts are made of special materials, so there is no need for maintenance

Note: 1. The special requirements of rubber expansion joint 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 rubber expansion joint can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the rubber expansion joint above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the rubber expansion joint shall be installed with anti falling device.
