1. Introduction to the Contract for Oil-Resistant Rubber Joints with the People’s Liberation Army 7431 Factory:
2. Introduction to Oil-Resistant Rubber Joints with the People’s Liberation Army 7431 Factory:
Economic Efficiency: Compared to mechanical expansion joints and filler damping, rubber expansion joints occupy less space, are lightweight, easy to install and dismantle, labor-saving, and cost-effective. For the same limit capacity, there is no need to increase the pump and pipe diameter. The smooth inner wall of the rubber joint reduces fluid resistance and does not damage the pipe body. It has good water tightness, and no gasket is needed during installation. Wide Applicability: Different rubber formulations can be chosen to provide the product with various properties such as heat resistance, corrosion resistance, aging resistance, ozone resistance, etc. Broad Temperature Resistance: Reasonable formulations (materials) can make the product resistant to temperatures ranging from -20 to 120°C. Long Service Life: This product can generally be used indoors for more than 5 years.
Displacement Capability: It has good adaptability to compression, tension, torsion, vertical displacement, etc., preventing damage to the pipeline system caused by deformation due to thermal expansion and contraction or uneven foundation settlement.
Installation Guidelines:
When choosing flat welding flanges for the pipeline, the following standards should be adopted (for special butterfly valve flanges). The sealing surface of the rubber joint and the sealing surface of the soft-sealed butterfly valve both require a special butterfly valve flange for sealing to achieve optimal results.
The inner diameter of the connection point on the water pipeline must be the same as the inner diameter of the rubber shock absorber joint.
The flange in contact with the water pipeline connection must have a smooth and flat contact surface to ensure the maximum sealing space. If the rubber vibration absorber joint does not have a tight connection with the water pipeline contact surface, noise, insufficient pressure, and water leakage may occur.
