The pipeline rubber product introduction: Product features: (1) good corrosion resistance, long service life, cement pipe glass steel pipeline interface rubber sealing ring, can resist all kinds of acid, alkali, salt, organic solvents and sea water, sewage and other chemical media for long-term corrosion, according to different media types and the use of temperature, choose different material sealing ring. (EPDM rubber, natural rubber, fluorine rubber, butyl rubber, neoprene) ozone aging resistance and the storage life of up to 50 years, consistent with the pipeline life. (2) excellent physical and mechanical properties, the main performance index is better than the United States ASTMF477 standards: Hardness: 50 A ~ 70 A; The tensile strength: not less than 9Mpa; The elongation at break: 380%; The compression deformation is less than or equal to 25%; Working temperature: -50 to 250 DEG c; (3) non toxic, non polluting, less joint, sealing and reliable Through the use of food grade rubber raw materials produced by the sealing ring non-toxic, non pollution, and the surface has a thin layer of protective film, both to increase the anti aging performance, and can resist the erosion of the microbial, no pollution to the water quality, so that it can be used for the transport of water seal. II the use of non joint molding, joint, less resilient, compression, according to different working pressure, design different hardness level, so as to make different pressure grade and special performance of sealing ring, working pressure rating from 0.25Mpa-4.0Mpa, can also be based on customer demand to produce other pressure grade sealing ring. The "section, convenient installation, large amount of compression (compressed 20% ~ 50%) by the tens of thousands of tests and found no leakage (4) using new materials, new technology, resistance to stress, small deformation, good sealing, temperature resistance 100-150. Can also be designed and manufactured according to the requirements of the buyers. (5) the special section, good location, reliable sealing performance and application to underground pipelines with flexible interface alternative rigid interface to solve the soft soil geological conditions, caused by differential settlement of pipeline leakage, water supply and drainage rubber tube sealing ring for drainage pipeline project, installed at the two interfaces, with good sealing performance.
