Axial expansion joints are designed to compensate axial movements (extension and compression) in its longitudinal axial direction due to thermal expansions and absorb the mechanical vibrations and reduce sound on pipe line systems (pumps, compressors, fans). The standard expansion values of axial expansion joints (metal bellow expansion joints) are 30 mm and 60 mm. Upon customer request special expansion values and sizes will designed and produced. If smoothness is needed or if high frequency vibrations or turbulence are expected in the flow media Axial Expansion Joints (Metal Bellow Expansion Joints) should be used with Liner. Liner material also can able to eliminate resonance caused by the fluid passing trough the bellows and minimize the contact surface of the fluid. Contact surface of the expansion joint can be minimized by using axial expansion joints with liner.

1, Product Information: Rubber flange expansion joint is a flexible connector fabricated of nature or synthetic elastomer, steel ring and fabric. When necessary, metallic reinforcement will be used to provide stress relief in piping systems. It can resist the thermal and mechanical vibration and/or movements. Movement always happens in the piping systems due to varying ambient temperatures, temperature difference when handle materials, and different composition of the joints. Expansion joints can absorb this movement, eliminate the danger of buckling, and reduce the high replacement costs that would result. The Engineers from ZHW will solve the anticipated problems in piping system, including vibration, noise, shock, corrosion, abrasion, stresses and space, by connecting rubber flange expansion joints with it. 2, Product Applications: Due to the rubber expansion joint has good comprehensive performance, mainly used for lifting and conveying, raw water and sewage water of coal-fired power plants, cooling circulation water, condensed water slurry circulation, metallurgical industry, chemical industry chemical pipelines, cooling of the petrochemical industry, the length of the dilution and other industries flexible connection between the distance line. Because the rubber has high wear resistance, but also applies to all industries of granular and powdered and gas transport in low temperature. In addition, in order to guarantee the construction quality, designers and users warned, if the product is installed close to exit of a pump or at the corner of pipes, a caging devices against disjunction must be noted for installation. In general, if there is any hidden trouble in your operation, relevant operation conditions must be noted in your order, and you will get a satisfactory reply. 3, Product Features: High pressure, good elasticity. Large deformation displacement. Noise damping effect, flexible. Long service life. Can be widely used in hotels, factories, residential plumbing systems and recycled water pipes, sanitary pipes, chemical corrosion and frozen pipes etc.
