The double-layer abrasive material injection pipe is mainly designed to transport abrasive, sandblasting and shot peening materials. The rubber used inside has excellent wear resistance under the condition of good electrical conductivity. The pipe conveys many media. With strong friction, this type of choice can well protect the use of the pipe body, and the rubber used in the outer layer has good wear resistance and oxidation resistance. The design is rare in China, it can well protect the use of the tube body and prolong the service life. Black wear-resistant and anti-static NR&SBR synthetic rubber/UPE (the inner rubber material is selected according to the properties of the medium) constitutes the inner layer of the heavy-duty material suction and discharge pipe, and gives it high chemical stability, wear resistance and corrosion resistance. Among them, the inner layer of UPE material with the reputation of "wear-resistant king" makes the heavy-duty material suction and discharge hose far superior to the traditional rubber conveying hose in terms of medium flow rate, wear resistance and aging resistance. Luohe Litong Hydraulic Technology Co., Ltd. closely focuses on the upstream and downstream industrial chains of rubber pipes to carry out technical research and development and production of oil drilling and production hoses, food and drug pipes, rubber gaskets, fluid connectors, etc., providing services to buyers of global equipment , Litong gradually finds its own way in the world market, contributes to the global intelligent manufacturing, and strives for the great goal of becoming the leader of the global fluid technology industry. Improper use Under the premise that the quality is guaranteed, if the use is improper, the service life of the hose will be greatly shortened. In practice, most of the damage to high-pressure hoses is caused by improper use. Subject to frequent and violent pressure shocks. The high-pressure hose is bursting, usually not because of too much static pressure, but related to the violent level and number of pressure shocks. When the construction machinery is working, the sudden increase or decrease of the oil pressure in the oil pipe will repeat, which will cause frequent pressure shocks to the oil pipe, resulting in aggravated damage to the oil seals of various parts, foaming and cracking of the rubber hose, and damage to the pipe joints. Loose leaks. Therefore, during operation, the valve stem cannot be pulled too hard, and it must be steep. The company invests heavily in research and development of polymer materials, which have been used in hydraulic transmission, industrial fluid hoses, oil drilling and production hoses, FDA food and medicine hoses , rubber seals, fluid connectors and other materials, food pipes have obtained FDA certification, and oil drilling and production hoses have obtained API certification. The products are more competitive, and the grades and application scenarios are improved. The high-end oil drilling and production hose industry has passed the API certification in line with API 7K, 16C certification. Founded in 2003, the company has developed into a large-scale enterprise with an annual output value of 300 million yuan in just ten years. In 2019, it continued to invest in the introduction of high-end production equipment and experimental equipment, adhering to high-end and insisting on innovation. Litong Hydraulic Technology Co., Ltd. currently has 36 scientific and technical personnel, including 2 professors, 2 doctoral students, 6 senior engineers and 26 engineers. Litong owns the CNAS-Henan Laboratory High-Pressure Rubber Hose Engineering Technology Research Center, and jointly established the Litong Qingdao Research Institute with Qingdao University of Science and Technology.
