Litong chemical conveying hose has the characteristics of long service life and wide application range. Its structure is woven from one or more layers of reinforced high-strength steel wire. The inner and outer liners of the hose are extruded and the inner liner is made of a series of compound rubbers. The tube body is soft, high strength, good elasticity and good wear resistance. Steel wire is added to the tube to enhance the overall performance of the tube. It has the characteristics of low calorific value, good elasticity and long service life. Rubber hoses have good positive and negative pressure resistance, acid resistance, alkali resistance, oil resistance, high temperature resistance, etc., and can transport more than 90% of today's chemicals.
The high-pressure air pipes produced by Litong Hydraulics are mainly used for high-pressure air transportation, compressors, etc. In 2015, our company established a cooperative relationship with a large shipyard with an annual output of 10,000 meters. Long-term supply of air pipes, hydraulic pipes, etc., raw materials, nitrile rubber and traditional rubber pipes. It has obvious aging resistance, and the surface does not appear to crack uniformly after more than five times of outdoor use. The quality of our products is trusted by our customers, which is the driving force behind our unremitting efforts. Corrugated PTFE hose is a very versatile hose with excellent flexibility and large size in both length and inside diameter. Current users see it as the ideal bulk transfer hose for a wide range of caustic, chemicals and raw materials. Their applications include tanker and ship unloading, bulk handling, chemical and petrochemical transfers, pump connections, and more. The hose can also be used as a suction hose for unloading or transferring media under negative pressure, giving customers more room for choice.
The first-phase project of the Industrial Fluid Smart Industrial Park was completed in 2019 and went into full production smoothly. It has professional analytical instruments, imported Italian Bierma pulse test bench, Italian Bierma curved pulse test bench, and Litong Testing Center was awarded by the Henan Provincial Department of Science and Technology The title of "High Pressure Hose Engineering Technology Research Center". As China's first professional R&D and testing center for rubber hoses, this is undoubtedly another step in Litong's research and technology development. Anti-aging agent D is N-phenyl-β-naphthylamine (D), which is a kind of anti-aging agent commonly used in the production of rubber products, which is anti-aging and anti-fatigue aging. Using a small amount of antioxidant D in the protection system can improve the heat aging resistance of the rubber compound, thereby improving the heat resistance of the acid and alkali resistant hose, expanding the use temperature range and prolonging the use time.
Under the same conditions of pressure resistance, the oil delivery composite hose is better than the rubber hose of the same specification. It can still work normally under a small radius of gyration, and its bending parts are always round, and will never fold, fall off the inner wall, block and break the tube. Due to the use of laminated galvanized sheet structure, it has good pressure resistance, and the hose will expand and contract when charging and decompressing. It is mainly used in petroleum exploration, petroleum refining, sewage oil treatment, petrochemical storage, storage of animal and vegetable oils, shipbuilding industry, oil port terminals, petroleum products aviation fuel oil, etc.
