Double sphere rubber joint

Double sphere rubber joint can greatly reduce piping system of vibration and noise, double sphere rubber joint can solve all kinds of pipeline interfaces displacement, axial expansion and concentricity wait for a problem. According to the material is different can be made into acid and alkali resistance, corrosion resistance, oil resistance, heat resistant etc. Each variety, suitable for various kinds of medium and environment. Materials and sealing of polarity rubber, light weight, easy installation and maintenance, adapt to life is long, but avoid contact with sharp metal devices, lest prick sphere. Such as aerial applicable can match elastic support, installation bolt to tighten with diagonal method.
Line pressure is high, the application limit bolts will both ends flanges together.
Product by inside fillet, multi-layer nylon cord fabric reinforced, spirallayerand ext-ernal rubber double sphere and composite composed of metal flange loose. Has the high voltage, flexibility is good, displacement double shape size, shock absorption noise reduction effect is obvious, installation flexibility of characteristics, can be used for water, hvac, textile, papermaking, petroleum, ship, chemical, compressor, water pump, fan blower piping systems.
