Axial expansion joint nbr anti-vibration single sphere flange flexible
Axial expansion joint is commonly known as rubber joint. Axial expansion joint is widely used in water, electricity, chemical industry and ship mooring system. The axial expansion joint can be automatically extended with the natural change of weather during use. The structural material of the axial expansion joint is nylon cord fabric, and the inner and outer surfaces are made of high strength aging resistant polar rubber. In order to prevent the natural shrinkage and reduce the aging fracture of axial expansion joint in long-term use, steel wire is used for multiple protection.
Performance characteristics of axial expansion joint
Properties of axial expansion joint, such as high elasticity, high air tightness, medium resistance, weather resistance and radiation resistance, etc. The axial expansion joint is made of polyester cord fabric with high strength and strong cold and hot stability, which is cross compounded with it. After high pressure and high temperature molding and crosslinking, it is resistant to forming. The axial expansion joint has high internal density, can withstand high pressure and excellent elastic deformation effect. The axial expansion joint structure design section arc height, long curve, has a large multi-directional displacement function. It is especially suitable for places with complex geological conditions, large settlement radiance and frequent cold and hot changes during pipeline operation, which are easy to cause pipeline operation. The axial expansion joint can effectively eliminate the displacement and physical damage of the pump, valve and pipeline itself by using the elastic sliding of rubber and the heat transfer function of deformation mechanical force. Because the rubber of the axial expansion joint is a bad conductive material, the axial expansion joint is an ideal environmental protection product for reducing vibration and noise transmission.

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