1. Union flexible joints also called flexible joint, rubber expansion joint, rubber flexible joint, pipe expansion joint, soft rubber joint etc. The product can endure high pressure, maintain good elasticity, have large displacement to balance pipe deviation, absorb vibration and make less noise and have easy installation, etc. Which can used for both suction and delivery (discharge) due to its excellent stability and pressure with standability. Its bursting pressure is anytime above 550psi and can be comfortably used within a normal internal pressure of 225psi. Which are widely used in piping and equipment systems to prevent vibration, noise, thermal expansion and contraction and stress fluctuations. Besides they are also widely used in the pipe system of water supply, drainage, circulating water, HVAC, fire protection, paper making, pharmacy, petroleum chemical industry, ship piping system, water pump, compressor and fan etc. The normal type is used to transport air ranges from - 15 °C to 115 °C, compressed air, water, sea water, oil, acid and alkali etc. The special type is used to transport the media above ranges from - 30 °C to 250 °C above, oil or strong alkali, strong acid and solid material.
