Product Introduction

The rubber expansion joint is generally composed of a smooth waveform compensation element with rubber flanges at both ends and a metal flange. Loose tube structure is often adopted for metal flange.
The surface of the waveform compensation element is rubber, and the inner layer is sandwich reinforced by several layers of strong fibers or steel strips (wires). Reinforcing fiber or steel strip (wire) and other reinforcing interlayer extend to the rubber flange at both ends, and there is a hard steel wire skeleton in the flange. The rubber expansion joint has a large displacement compensation capacity, which can compensate the axial, transverse and angular displacement, reduce noise, reduce vibration and have a certain anti-corrosion capacity. It is characterized by high pressure resistance, good elasticity, large displacement, good vibration absorption and noise reduction effect, and convenient installation, and can be widely used in water supply and drainage, HVAC, fire protection, compressor, paper making, pharmaceutical, ship, water pump, fan and other pipeline systems.

The rubber expansion joint is a rubber connector. The utility model relates to a hollow rubber product used for flexible connection between metal pipes. According to the connection mode, it can be divided into loose flange type, fixed flange type and threaded type; According to the structure, it can be divided into five types: single sphere, double sphere, reducer, arc sphere, air pressure coil, etc. Tubular rubber parts are composed of inner and outer rubber, cord layer and steel ring, which are loosely assembled with metal flanges or parallel joints after vulcanization molding. The product can reduce vibration and noise, and can compensate thermal expansion and cold contraction caused by temperature change. It is widely used in various pipeline systems.

Feature

The key features of  PTFE lining are as follows:

1. Insulation: it is not affected by environment and frequency, the volume resistance can reach 1018 Ω/cm, the dielectric loss is small, and the breakdown field strength is high.

2. Corrosion resistance: except for molten alkali metal, the effect of fluoride medium and all strong alkalis, oxidants, oxidants and various organic solutions above 300 ℃ except sodium hydroxide (including aqua regia).

Benefits

Rubber expansion joint has ultra-high performance, reliability and service life, so it can improve plant safety and mechanical integrity of equipment.
1. This product can greatly reduce the vibration and noise of the pipeline system, and fundamentally solve the problems of joint displacement, axial expansion, misalignment, etc. of various pipelines.
2. According to different materials, it can be made into acid resistant, alkali resistant, corrosion resistant, oil resistant, heat resistant and other varieties, which are suitable for a variety of media and environments.
3. The material is polar rubber, with good sealing performance, light weight, convenient installation and maintenance, and long service life. However, it is necessary to avoid contacting sharp metal appliances to avoid piercing the sphere.
4. If it is used overhead, it can be equipped with elastic support, and the bolts shall be tightened diagonally during installation.
5. If the pipe pressure is too high, use limit bolts to connect the flanges at both ends together.
6. The working pressure grade of this product is 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa, etc.
