商品名稱: Concentric reducer rubber joint

Rubber expansion joints, also known as rubber bellows, rubber joints, single ball flexible connections, expansion joint bellows, etc., are mainly composed of two flanges and a rubber sphere. The flange is used for connection. The rubber sphere is flexible and can absorb Axial, horizontal and circumferential displacement, the normal working pressure is 16bar, the normal working temperature is -15~+80 degrees Celsius, the standard size is DN25-DN3000, the standard material of rubber is natural rubber, EPDM, neoprene, NBR and PTFE The normal material of flange is carbon steel galvanized, carbon steel spray paint, cast iron spray paint and stainless steel, etc. It has the characteristics of high pressure resistance, good elasticity, large displacement, shock absorption and noise reduction, flexible installation, etc. It can be widely used in water supply and drainage. , circulating water, HVAC, papermaking, petrochemical, ships, compressors, pumps, fans and other pipeline systems.
