Shrink concentric expansion compensator reducer metal flange flexible rubber expansion joint

Product introduction of concentric reducer rubber joints

Concentric reducer rubber joint is a flexible connector used to connect pipes of different diameters, which is mainly used in metal pipeline systems to solve the problem of pipe connections of different diameters, and has the function of shock absorption and noise reduction. It is composed of a rubber sphere composed of an inner rubber layer, a nylon cord fabric reinforcement layer and an outer rubber layer and a loose metal flange, which has the characteristics of high elasticity, high air tightness, medium resistance and weather resistance.

Concentric reducer rubber joint structural features

Concentric reducer rubber joints are usually composed of rubber bodies, metal flanges, bolts, and gaskets, etc. The rubber body part adopts a concentric reducer design, that is, the diameter of the two ends is different, one end is a large diameter, and the other end is a small diameter, which enables the joint to connect pipes of different diameters to achieve smooth fluid transmission between different pipes.

Application areas of concentric reducer rubber joints

Concentric reducer rubber joints are widely used in water supply and drainage, circulating water, HVAC, fire protection, papermaking, pharmaceutical, petrochemical, shipbuilding, water pumps, compressors, fans and other pipeline systems. The ordinary type is suitable for the medium of -15°C~120°C, and the special type is suitable for the medium above -20°C~150°C.

A common type of concentric reducer rubber joints

Concentric reducer rubber joints are divided into concentric equal diameter, concentric reducer and eccentric reducer according to their shape. According to the structure, it is divided into single sphere, double sphere, triple sphere and elbow sphere. According to the connection form, it is divided into flange connection, threaded connection, and threaded pipe flange connection. According to the working pressure, it is divided into five grades: 0.25MPa, 0.6MPa, 1.0MPa, 1.6MPa and 2.5MPa.
