DIN/BS/JIS/API PN16/25/150LB Carbon Steel Flange Pipe Expansion Joint

Introduction

Rubber joints are also called rubber pipe soft joints, flexible rubber joints, rubber soft joints, flexible rubber joints, high-pressure rubber joints, rubber shock absorbers, compensators, etc. According to the connection mode, it is divided into loose flange type, fixed flange type and threaded type; According to the structure, it can be divided into 5 kinds: single sphere, double sphere, reducer, curved sphere and wind pressure coil. The tubular rubber part is composed of inner and outer layer rubber, cord fabric layer and steel ring, which is vulcanized and formed, and then combined with metal flange or loose sleeve of parallel joint. This product can reduce vibration and noise, and can compensate the thermal expansion and cold contraction caused by temperature change. It is widely used in various pipeline systems.

Equipment Structure

Rubber joint can also be called: flexible rubber joint, rubber soft connection, soft joint, flexible rubber joint, rubber expansion joint, shock throat, shock absorber, etc. it is a pipe connector with high elasticity, high air tightness, medium resistance and climate resistance.

The rubber joint is generally composed of inner rubber layer, fabric reinforcing layer (the reinforcing layer has multi-layer scraped nylon cord fabric), middle rubber layer, outer rubber layer, end reinforced metal ring or steel wire ring, which is combined with metal flange or parallel joint loose sleeve after high temperature and high pressure vulcanization. This product takes advantage of the high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance of rubber, which can reduce the vibration and noise of pipeline, and compensate the thermal expansion and cold contraction caused by temperature change.

According to different media, the rubber materials used are also different, including natural rubber, styrene butadiene rubber, butyl rubber, nitrile rubber, EPDM, neoprene, silicone rubber, fluororubber, etc. It has the functions of heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance and oil resistance.

Application Area

Because the flexible rubber joint has good comprehensive performance, it is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and light industry, refrigeration, sanitation, plumbing, fire control, electric power and so on. According to different materials, it can be made into various varieties such as acid resistance, alkali resistance, corrosion resistance, oil resistance, high temperature resistance, radiation resistance, wear resistance and aging resistance, which can adapt to a variety of media and environment.
