304 stainless steel wire fastener internal thread flexible rubber soft joint
Product Composition
1. Inner rubber layer: The inner rubber layer is in direct contact with the medium, and is usually made of high-quality rubber materials with good corrosion resistance and wear resistance. It not only needs to have pressure resistance, but also good chemical resistance to adapt to different working media and temperature conditions.
2. Reinforcement layer: The reinforcement layer is a key part to improve the compressive and tensile strength of rubber joints, usually composed of high-strength fiber materials or steel wires. This layer is designed to allow rubber joints to maintain their stability under higher pressures and loads, while providing the right amount of elasticity.
3. Outer rubber layer: The outer rubber layer is used to protect the internal structure of the rubber joint from the external environment, such as sunlight, rain, oil pollution, etc. The outer rubber layer is generally required to have good anti-aging and corrosion resistance to prolong the service life of rubber joints.
4. Flange or threaded joints: The two ends of rubber joints are usually made of steel flanges or threaded joints to facilitate reliable connection with the pipeline system. The material and processing accuracy of the flange directly affect the installation quality and sealing performance of the rubber joint.
How the product works
Combined threaded rubber expansion joints work by absorbing displacement, vibration, and pressure fluctuations in the piping system through the expansion and deformation of their elastomers. Specific features include:
Absorption of vibration and noise: The elastic properties of rubber joints allow them to effectively absorb mechanical vibrations, reduce noise transmission and improve the working environment.
Compensation displacement: When the displacement of the pipeline system due to temperature changes, pressure fluctuations or installation errors occurs, the rubber joint is compensated by its own flexible deformation to ensure the stability of the pipeline connection.
Cushion pressure fluctuations: During fluid transfer, the flexible material of rubber joints can produce moderate deformation when subjected to transient pressure fluctuations, mitigating pressure shocks in piping systems.
