Pipe Flexible Fittings DN150 Rubber Expansion Joint Seal With Flange
The flexible fittings 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. Flexible fittings can reduce vibration and noise, and can compensate the thermal expansion and contraction caused by temperature changes. Flexible fittings have been widely used in various pipeline systems.According to different media, the rubber materials used in flexible fittings 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 flexible fittings
1. The flexible fittings has the advantages of small size, light weight, good ductility and convenient installation and maintenance.
2. Flexible fittings installation can cause horizontal, radial, angular offset, will not be limited by the pipe plug center, flange uneven surface.
3. When the flexible fittings is working, it can reduce the structure transmission noise and has strong vibration absorption ability.

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