Concrete wear-resistant hose (A, B, C, D pressure from low to high) C type and D type: their working pressures are about 6MPa~8MPa, 78MPa~8.58MPa, respectively, and have higher requirements for pressure resistance, enhanced The layers are typically wire-wound structures. And under high pressure conditions, its wear resistance needs to reach the original conveying capacity, which requires relatively high internal rubber. Generally, synthetic wear-resistant rubber with special technology is collected as the inner rubber. 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. The company regards scientific research talents as a strategic reserve, implements the talent introduction strategy, cooperates with Henan universities, and has a deep understanding in the field of new materials. Cooperate to introduce higher vocational talents to add new blood to the R&D team; recruit professors in the university industry to provide support for R&D; introduce high-quality foreign talents to integrate with international technology.
   At the same time, actively expand foreign business and set up offices to serve foreign markets. School-enterprise alliance to jointly establish Litong Qingdao Research Institute to provide sophisticated technology. In order to improve the replacement efficiency of the cement slurry and ensure that the cementing truck can efficiently complete the cementing construction task under high pressure, the LT301C high-pressure cement hose adopts 4-6 layers of wound super-strength and high-flexible steel wire or steel wire rope as the reinforcement layer. Tensile and other characteristics, effectively improve construction efficiency and ensure operation safety. The outer rubber layer is made of wear-resistant and weather-resistant synthetic rubber, which has the characteristics of flame retardant and ozone aging resistance, which greatly prolongs the service life of the hose and its service cycle (the super wear-resistant UPE outer coating can be customized).
    Oil is a precious underground energy resource, also known as industrial blood, which can be used in various fields of human beings and is an indispensable main energy source for human life. In order to develop oil, extensive exploration and extraction is the first step. The first step is to drill, using the appropriate drill pipe while drilling. Litong Technology has developed key hose products such as production fracturing, oil drilling and production, BOP well control, well killing fluid transmission, etc., which effectively solve the practical problems that customers care about. After the ordinary rubber hose is installed with the joint, the inner diameter of the joint part of the hose will be compressed a lot. The oil drilling and production hose we produce has the characteristics of equal diameter. When the medium flows through the joint, the generation of eddy current is reduced, the resistance is reduced, and the protection Rubber hose, avoid friction of inner layer, longer service life.
