Since May 2019, Litong has been actively building computerization and industrialization integration projects and providing customers with one-stop product and service support from the central office. Founded in 2015, Litong e-commerce platform, based on practical network resources, has opened up a broad domestic and international market for Litong fluid technology industry and greatly improved service efficiency and quality. The research and production of Litong hydraulic in steel wire wound hose drilling, including oilfield reinforcement, petroleum operation and geological survey, small oil drilling rig, hydraulic coal mining, transportation of sludge, water and other liquid media under ambient temperature, will be used in practical work. It can be used in various complex environments and is resistant to hydrogen sulfide and fire. Violation of acidification environment. When hydrogenated synthetic nitrile rubber is manufactured and used as the raw material of the inner layer of the pipe, it can withstand hydrogen sulfide to ensure safety. Blowing can be completed in the discharge state. In July 2012, our company was supported by the national technology innovation fund for small and medium-sized technology companies. In September 2012, the ultra-high pressure hydraulic project was put into operation, with an annual output of 10 million meters. In October 2012, six German Mayer 3x3 steel wire knitting machines introduced by the company were officially put into use. In November 2012, the company and Luohe supervision, inspection, technology and testing quality center jointly established a rubber hose laboratory. 300PSI furnace door coolant hose is the star product of Litong's main products, which is mainly used in iron and steel plants, glass plants or foundries. The pipe structure is composed of three parts. The interior is made of white EPDM rubber, the middle is reinforced with high-strength fiber cotton thread, and the outer layer is wrapped with a layer of EPDM rubber and wrapped with non-conductive and dust-free glass fiber. In addition, the outer layer of the fiber can also have strong heat resistance. The phase I project of industrial fluid intelligence Industrial Park was completed and put into full operation in 2019, with professional analytical instruments, Imported Italian Bierma pulse test bench, Italian Bierma meander pulse test bench, and Litong testing center were awarded the title of "high pressure hose engineering technology research center" by the Department of science and technology of Henan Province. As the first professional R & D and testing center of rubber hose in China, this is undoubtedly another step in Litong's research and technological development. As a flexible pressure pipe fitting, high-pressure hose is installed in the liquid transportation system. It has many advantages, such as good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance and so on. High pressure hose is made of imported materials. Among them, stainless steel wire braided hose, fluid conveying metal bellows, stainless steel pump vibration damping hose, stainless steel fire hose, stainless steel bellows compensator and stainless steel bellows of gas machinery. The product has the advantages of good flexibility, corrosion resistance, fatigue resistance, high and low temperature resistance, shock absorption and noise reduction, strong sealing, long service life and so on.
