Features of this product: Using cis-butyl and butyl rubber as the main raw material for the inner rubber, and then adding special reinforcing agent, the rubber hose produced can achieve high wear resistance and high toughness. In addition, the use of high-quality and high-strength cords as the reinforcement layer can make the hose have the characteristics of high pressure resistance and good torsion resistance. In the process of oil extraction, the geographical location and relative environment of each area are different, so well control hoses are required, which are suitable for most areas. Based on the manufacturing process of four-layer winding high-pressure hydraulic hose, Litong BOP well control hose uses refractory rubber as the raw material for the outer rubber layer of the hose, and is covered with stainless steel armor on the outside of the pipe body. In extreme cases, in order to achieve the effect of fire and fire resistance. Litong's 17th anniversary is April 16th. On this day in 2003, Litong was officially established. At the time, the scope of Letone was unclear nationally, but the founders believed that Letone had become a global leader in the liquid technology industry, paving the way for entrepreneurship. The idea must have been crazy at the time, but now, 17 years later, this seemingly impossible dream is gradually becoming a reality. Our high pressure drilling hose manufacturers cover all drilling applications offshore or onshore. Swivel hoses meet the highest demands of the latest API 7K specification, while our gas choke and kill lines exceed the demanding API 16C specification. It is usually used for water delivery in oil field, cement restoration, geological exploration and coal mining, the production of Litong restrictor pipe has passed ABS product design evaluation certification (project approval) and production evaluation certification (factory license), which means Litong API 16C pipe is suitable for design projects. It is also possible to produce oil at sea and on land. PTFE Teflon hose is a kind of industrial hose with perfect combination of rubber and PTFE resin. Teflon hoses are produced from PTFE resin with high elasticity and low microporosity. In many industrial and technical processes, the temperature range between -70 ℃ to 260 ℃ this hose is a good choice. It is more resistant to peroxides than ordinary rubber tubing today. It is therefore more suitable for use in the automotive, motorcycle and marine industries. In the marine industry this hose can be used for ships and boats. The present invention adopts food grade UPE inner tube, which can be used in high concentration and/or high temperature conditions, and has good resistance to the most severe cleaning in place (CIP) methods and substances (such as commonly used chemical cleaning), At the same time, its wear resistance is also time-tested, which fully meets the transportation suction and discharge of solid materials. Even steam up to +130°C can clean for 30 minutes. In addition, the inner barrel material is guaranteed to be odorless and tasteless, and the inner wall of the hose is free of phthalates.
