4inch 100mm End Face Flange Flexible Natural Rubber Expansion Joint Fully Sealed

Product Specification

Product Introduction

      The fully sealed rubber joint on the end face is mainly composed of three parts: rubber joint, flanged end and fastener. Its structure design is reasonable, the structure is simple, the installation is convenient, it is a new type of pipe connector.             

      Compared with ordinary rubber joints, end face fully sealed rubber joints can better adapt to the displacement changes of the axial and radial directions of the pipe, and have certain angular displacement and deflection angles. In addition, end face fully sealed rubber joints can also improve the load-bearing capacity of the pipe by increasing the thickness of the connecting flange.

Product performance characteristics

      1. High temperature resistance, oil resistance, aging resistance: Different types of end face fully sealed rubber joints have different performance characteristics, such as neoprene rubber joints have good high temperature resistance and aging resistance, while silicone rubber joints have the characteristics of cold resistance, ozone resistance and so on.
      2. Good comprehensive mechanical properties and bearing capacity: End face fully sealed rubber joints have high bearing capacity and strong tensile strength, and can adapt to various complex pipeline systems.
      3. Strong vibration absorption and noise reduction: The end face fully sealed rubber joint can reduce the noise transmitted by the structure when working, and has a strong vibration absorption ability, which is suitable for the environment that needs to reduce noise and vibration.
      4. Wide range of application fields: Because the end face fully sealed rubber joint has good comprehensive performance, it is widely used in chemical industry, construction, water supply and drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power and other basic projects.

Installation method of fully sealed rubber joint on the end face

1. When the rubber joint is installed, it is strictly forbidden to install beyond the displacement limit.
2. The installation bolts should be symmetrical, and gradually pressurized and tightened to prevent local leakage.
3. For working pressure above 1.6MPa, the installation bolt should have an elastic pressure pad to prevent the bolt from loosening during work.
4. When installed vertically, both ends of the joint pipe should be supported by vertical force, and anti-pull-off devices can be adopted to prevent the work from being pulled off under pressure.
5. The rubber joint installation part should be kept away from the heat source. Ozone area. It is strictly forbidden to expose to strong radiation rays and use media that do not meet the requirements of this product.
