Pipeline transportation of steam at 180 degrees Celsius generally uses rubber high-temperature and high-pressure steam hoses. The inner and outer layers of this hose are made of EPDM rubber, and the middle is braided with one or more layers of steel wire, which can withstand a maximum temperature of 200 degrees Celsius. In addition, its working pressure can also be increased according to the number of steel wire braided layers used in its reinforcement layer, and it can withstand a maximum working pressure of 20Mpa and a burst pressure of 170Mpa.
Over the past 17 years, Litong Hydraulics has insisted on taking continuous innovation and development as an opportunity to promote product technological innovation, speed up the pace of new product development, and actively attract outstanding talents. Now it has 55 technicians with a master's degree or above, and the R&D team and Qingdao University of Science and Technology established Rubber Research Institute, strengthen school-enterprise cooperation, adhere to research and development innovation, continue to launch new products, launch new fluid solutions, and have a complete service team. Litong Hydraulics has been improving the performance of pipes for many years, trying to minimize the friction of pipes, among which reducing the viscosity of rubber is one of the main factors. After scientific experiments, technicians have discovered a softener, which can make pipes The temperature of the internally flowing rubber material is lowered, and the viscosity of the internal rubber material can also be reduced. Based on this advantage, during the use process, the rubber material flows more smoothly, and also reduces the expansion and speed. This technology effectively reduces the glue material viscosity.
The total investment of the Litongtong Fluid Technology Intelligent Industrial Park project is as high as 1.65 billion yuan. And on the basis of the current development, it plans to invest 1.35 billion yuan to build 90 rubber tube composite production lines, adding an annual output of 105 million meters and creating an annual production capacity. 120 million meters of rubber composite hose technical field industrial park. The new project is divided into two phases with a construction period of 3 years. PTFE is a new type of rubber material. It has strong corrosion resistance when conveying strong acids and alkalis. The hose is super wear-resistant. This hose is mainly used for special chemicals, cooling water, waste gas and other materials. The safety performance of the hose itself is relatively high, but for safety reasons, it must be checked regularly to avoid abnormal situations.
Characteristics and structure of petrochemical hose mine transportation pipeline: The inner rubber of the slurry transportation pipeline is made of polyurethane and butyl rubber as the basic raw materials, and special reinforcing agents are added. The color of the inner rubber of the finished product is transparent, with super wear resistance and toughness. High, high pressure resistance and other characteristics, the wear resistance index is 2-3 times that of the general sandblasting pipe. Reinforcing layer: The sandblasting pipe with cloth is made of rubbing cloth as the reinforcing layer, which has good flexibility and strong pressure bearing capacity; It has the characteristics of high pressure resistance and good flexural resistance.
