? Soft rubber joints commonly known as flexible rubber joints, its products are widely used in water, electricity, chemicals, boating system, the main performance, high pressure, good elasticity (axial, lateral and angular displacement) noise reduction, light weight, reduced vibration, easy to install, flexible, easy to replace them repair, but with acid, alkali, oil and so on. The shock absorber during use, weather-resistant natural changes can be automatically extended. Structural materials used dipped nylon cord, the inside and outside of high-strength anti-aging-polar rubber material, to prevent the natural shrinkage and reduction of the product in the long term aging rupture, using multi-wire mesh body protection. Can replace widely used in power plants, water plants, sewage plants, chemical industry, metallurgy industry, other telescoping products, the China Architecture Design Institute, petrochemicals department, Ministry of Metallurgical joint inspection, sampling, testing, the main technical indicators, work pressure, pressure vacuum degree, suitable temperature and applicable media (acid, alkali) have reached the appropriate indicators, are designated as "recommended products" and "designated products" in the industry, the main material neoprene, natural rubber and EPDM use of the product on humans do not pollute, does not have any side effects.
