Rubber joints, as mechanical connectors, are widely used in fields such as chemical engineering, petroleum, shipbuilding, etc. When using it, we first need to judge its quality to ensure its normal operation and safety. Usually tested in terms of appearance, hardness, corrosion resistance, stretching process, etc
Appearance
Firstly, observe the appearance of the rubber joint. A good rubber joint should have no defects such as bubbles, cracks, or burrs, and the surface should be smooth and flat. If the rubber joint has the above defects, it will affect its sealing performance and service life.
Hardness
Secondly, check the hardness of the rubber joint. The hardness of rubber joints refers to their compressive strength, which is generally measured by a hardness tester. A good rubber joint should have appropriate hardness, neither too hard nor too soft. If the rubber joint is too hard, it will be difficult to bend and connect during installation, which can easily cause damage; If the rubber joint is too soft, it will easily cause deformation, aging, cracking and other problems during use, affecting its service life and sealing performance.
Corrosion resistance
Thirdly, check the corrosion resistance of rubber joints. A good rubber joint should have good corrosion resistance and be able to adapt to different media and working conditions. In practical use, we can test the corrosion resistance of rubber joints by injecting different media into them. If the rubber joint cannot adapt to different media and working conditions, it will cause it to lose its sealing performance and load-bearing capacity, thereby affecting the normal operation of equipment and production.
Tensile strength
Fourthly, test the tensile strength of rubber joints. The tensile strength of rubber joint refers to its tensile capacity, which is generally measured through Tensile testing. A good rubber joint should have high tensile strength and be able to withstand the tensile and extrusion forces of the equipment during operation. If the tensile strength of the rubber joint is insufficient, it will be prone to problems such as fracture and cracking, which will affect the normal operation of equipment and production.
Installation process
Finally, check the installation process of the rubber joint. The installation process of rubber joints is directly related to their sealing performance and service life. A good rubber joint should adopt the correct installation process, such as ensuring the torque of the connecting bolts, applying appropriate lubricants, checking whether the flange connection is centered, and so on. If the rubber joint is not installed correctly, it will cause problems such as looseness and leakage during use, which will affect the normal operation of equipment and production.
In summary, judging the quality of rubber joints requires comprehensive consideration from multiple aspects such as appearance, hardness, corrosion resistance, tensile strength, and installation process. In addition, different materials can also affect the quality of rubber joints. Only by ensuring the quality of rubber joints can we effectively ensure the normal operation of equipment and production, and achieve safe and efficient production goals.
