The reinforcement layer is woven or wound with glass fiber, polyester fiber or nylon fiber. The cover uses chlorohydrin rubber, acrylate rubber or chlorosulfonated polyethylene rubber instead of neoprene. In addition, polyamide is also used in the inner rubber layer. For example, the fuel hose produced by Henan Luohe Litong Hydraulic Technology Co., Ltd. is coated with nylon 6 film on the inner layer of nitrile rubber, which can make the fuel permeability of the hose reach 0.004ml/cm2· 24h or less. In August 2019, we won the title of “Civilized and Integrity Enterprise of the Year”, and in the same year, we made major breakthroughs in the field of technical research, successfully developed fluid hoses, as well as ultra-durable clean hoses, drilling and oil pipelines, and PTFE/ HNBR hose “KING HOSE” series, with the growing maturity of technology, Litong has gone abroad and become an international big brand. If the inner rubber material of the steam hose is EPDM rubber with a rubber content of 60%, the outer rubber is also used. High heat resistant ethylene propylene rubber, then steam rubber tube can be used to superheat high temperature water vapor or high temperature saturated water vapor. The biggest characteristic of EPDM rubber is its resistance to saturated water vapor. It can be used for a long time in saturated water vapor below 160 degrees Celsius, especially with Peroxide cure system. Because MPD’s single-piece design can at least reach the strength of the piping system, the dynamic response of the MPD drilling fluid return hose is maximized. The MPD system generally diverts the return oil to the control manifold on board through two 6-inch ooze return hoses. Depending on the type of MPD system, a third hose is sometimes used to relieve pressure or supply fluid to control equipment.

The National Petroleum Drilling and Production Standardization Committee, established by the National Standardization Administration Committee, is mainly engaged in the standardization of drilling, production, and extraction equipment and tools in the oil and gas industry. At the same time, he also serves as the domestic focal point for the ISO/TC67 Committee of the International Organization for Standardization and the American Petroleum Institute (API). Moreover, our company has successfully obtained the API7K16D and other certification certificates of the association, indicating that the high-pressure wear-resistant hoses produced by our company have corresponding international standards. Super Hercules Wire Braided Hose is suitable for transporting water-based, petroleum-based hydraulic fluids and biodegradable hydraulic fluids in harsh working environments such as excavators and other construction machinery, construction machinery, mining machinery and agricultural machinery. The tube body has the characteristics of ultra-low bending. Its reinforcement layer uses one or two layers of braided high-strength and super-flexible steel wires. The first layer of pulses is ≥300,000 times; the second layer of pulses is more than 600,000 times. A big plus, it has 5+ years of weather resistance and comes with a 2-year warranty (using a dedicated one piece fitting from Leeton), a standard not found on other pipe bodies.
