LT1003 75PSI radiator hose rubber selection refers to EPDM rubber, and its glue content reaches 45%. The EPDM rubber layer selected on the surface of the tube body is smooth and slightly textured, with wear resistance and anti-aging properties. Its tightness is strong, which can ensure the operation of the pipe body. The reinforcement layer is made of polyurethane fiber, which has good toughness and can continue to work under the pressure of 75PSI. Litong Hydraulic Technology Co., Ltd. has passed the national defense enterprise. The Central Development Enterprise Management Department issued a "Contractor Registration Certificate" for the enterprise. The content of the certificate is "After verification, Litong Hydraulic System complies with the provisions of equipment contractors, has been included and included in the "List of Equipment Contracting Organizations of the Chinese People's Liberation Army", and successfully completed the military industry certification." Litong Enterprise also established a company for national defense. specialized unit. The rotary drilling hose is used between the top of the riser and the left and right rotating joints, and the marine sand transportation hose is used for ultra-high pressure sand transportation between the cargo ship and the offshore drilling platform. The length is generally more than 135m. or the following), used between the pump and the drilling frame, i.e., the intake branch pipe of the riser, to adapt to different shafts and protect against vibration. Construct writing. It is composed of inner glue, inner glue protective layer, middle glue, steel wire coil layer and outer glue. In 2016, Litong successfully completed the accreditation of laboratories in China to open a hydraulic testing institution, successfully completed the Luohe Technology Innovation Award, and many other innovation awards, released the "Super Artery" series, and successfully released PTFE high, medium and low pressure series multi-purpose hose products , its application is very extensive, with heat resistance, corrosion resistance and other characteristics, in special environments, such as transporting high-risk gases, highly corrosive gases, etc. For seventeen years, Litong has always adhered to the principle of "honesty first, customer first\"\' Values, unremittingly promote the development strategy of "leading ideas, training first, rooted in lean, climbing first". Carry out technology research and development, and its manufacture of polymer materials, hydraulic hoses, industrial hoses, oil drilling hoses, food and pharmaceuticals Hose, rubber products and fluid connectors, focusing on serving the world around the upstream and downstream industrial chains of rubber pipes, equipment manufacturers contributing to global intelligent manufacturing, and striving to become the main goal of global managers in the field of fluid technology. Most of EPDM rubber is A saturated polymer with excellent aging resistance, aging resistance, electrical insulation, chemical resistance and impact elasticity. The main disadvantage of ethylene-propylene rubber is the slow vulcanization rate. While other unsaturated rubbers are difficult to use, self-adhesive The properties and mutual adhesion are very poor, so the processing characteristics are not good. The acidity and alkalinity of the anti-corrosion chemical hose are very high, and the anti-corrosion and anti-corrosion rubber joint products are purchased, and the anti-corrosion material is 50% ammonium sulfate, which is a strong Alkali brings a great challenge to the material properties of the product, so customers choose EPDM rubber joints for use in anti-corrosion chemical hoses.
