The companies and products served by Litong can also be seen in the petroleum industry. Litong has successfully passed the API Q1 quality management system certification of the American Petroleum Institute. Harsh working environment such as hydrogen sulfide. API 16D is certified by Lloyd's Register and has the characteristics of fire resistance and high temperature resistance. In oilfield extraction projects, most people only pay attention to the delivery pipe, but the tank pipe is also needed during the extraction process. Suitable for oil field vacuum tanks to handle crude oil and mud. But there is also a problem to be aware of, the 150psi corrugated fuel tank tube is only used for applications with less than 35% aromatics, and the double layer abrasive material injection pipe is mainly designed for conveying abrasive, sandblasting and shot blasting materials. The inner rubber also has excellent abrasion resistance with good electrical conductivity. The medium conveyed by the pipeline has strong friction. This choice can well protect the use of the pipe, while the outer rubber has good abrasion resistance and oxidation resistance, and the pinhole design is adopted in the process design. This kind of design is rare in China, it can well protect the use of the pipeline and prolong the service life. Customers use 304 stainless steel high pressure metal hose (armored fire hose), 304 stainless steel high pressure metal hose is a single-layer or double-layer stainless steel wire braid to improve strength and durability. Used in aviation, petroleum, chemical industry, metallurgy, electric power, papermaking, medicine, food, wood, tobacco, transportation and other industries. Performance characteristics: 1. Wear resistance: prevent the hose from being damaged due to collision or mechanical friction. The inner and outer layers of the high-pressure oil pipe wall are oil-resistant rubber, with braided steel wire or winding steel wire (2~4 layers) interspersed in the middle. Poor quality hoses will appear: the thickness of the hose wall is uneven, the steel wire braiding is too tight, too loose or the number of steel wire layers is too small, the outer rubber has poor air tightness, and the inner rubber is corroded and the sealing performance is poor, and high-pressure oil enters the steel wire layer and the steel wire at will. Layers lack adhesion. On September 14, 2017, the company was identified as "the designated enterprise of the people's bank of one. The company's Phase 3 project has officially begun deployment, doubling its annual production capacity again. Litong e-commerce platform was established in 2015, vigorously developing domestic and foreign markets, and transporting Litong products to the national and even global markets.
