LT1212 150PSI corrugated cold-resistant oil suction and discharge pipe body size can be customized according to customer requirements, generally up to 4 feet, the internal rubber used in the pipe body has a certain conductivity, and the color is black; the constant pressure of the pipe is 150psi, the lowest temperature can reach minus 54 degrees Celsius, and in the case of low temperature, it is also very flexible, its outer layer is made of a blue corrugated rubber, which has wear resistance, oxidation resistance characteristics, The service life of the pipe body is improved. For more than ten years, Litong Hydraulics has insisted on taking continuous innovation and development as an opportunity, focusing on promoting product technology innovation, accelerating the pace of new product development, actively attracting multi-disciplinary talents, focusing on new material research and development, and now has 55 technicians with a master's degree or above. The R&D team and Qingdao University of Science and Technology established the Rubber Research Institute, strengthened school-enterprise cooperation, insisted on R&D innovation, continued to launch new products, launched new fluid solutions, and had a complete service team. 2. Binding method The binding method is suitable for emergency repair of ruptured rubber hoses with pressure below 16MPa. The specific method is: apply one of the aforementioned glues commonly used in construction machinery to the ruptured part of the hose; wrap 2-3 layers of oil-resistant rubber with a width of 2-3 times the length of the ruptured part (each layer should be coated with glue) ); bind the wrapped oil-resistant rubber with No. 12 iron wire; wait for it to solidify. The corrosion-resistant rubber joint is composed of an inner rubber layer, a reinforcing layer with multiple layers of squeegee nylon cord fabric, and a rubber tube compounded by an outer rubber layer. Depending on the medium, the rubber material used is also different, including natural rubber, EPDM, silicone rubber, fluorine rubber, etc., which have the functions of heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, oil resistance and so on. It has the characteristics of high pressure resistance, good elasticity and easy installation.
