Distribution of wear-resistant pipe manufacturers in Europe

 Since the establishment of the company in 2003, Litong Enterprise has kept pace with the times through the spirit of hard work and continued to be listed on the New Third Board. More than uniformity of contract books for defense commodities. Qualification review, the establishment of Litong Europa subsidiary, the completion of unimpeded excavator network platform, the establishment of Qingdao Research Institute, and has been selected as "my country's Top Ten Enterprises" for many years, Litong will continue to maintain this honor, and Continuously improve independent innovation and strive to be stronger. Oil and gas development, storage, transportation, and refining are inseparable from pipes and weapons. Gas steering columns and pipes are called the "core points" of gas production, manufacturing and transportation. The quality and performance indicators of pipes and weapons and equipment are particularly important for the production safety of oil exploration, the application of excellent processing technology, and the improvement of production, quality and efficiency. Litong Hi-Tech has continued to forge ahead in the important, relevant and important technical problems in engineering applications, and has achieved a number of important scientific research achievements in technical research, product quality standards and transformation of scientific and technological achievements.  The service life of the rubber tube is a problem that customers are concerned about. In order to increase the service life of the skeleton seal, it is necessary to improve the temperature resistance of the commonly used plastic materials for the skeleton seal. After identifying the type of plastic, the vulcanized rubber system is important. For example, it is made of nitrile rubber, and the application of DCP chloroprene vulcanizate system software and its addition of vulcanized rubber modifiers (such as magnesium methacrylate) to improve the temperature resistance can reasonably improve the temperature resistance. Only if the skeleton seal is done in time, the stainless steel wire of the internal structure of the rubber hose can be well maintained, thereby improving the service life.  Four layers of stainless steel wire coiled high-pressure high-pressure oil pipe The key application is crude oil-based gear oil, and it is suitable for harsh standard operating environments. The internal structure is made of high-temperature oil-resistant styrene-butadiene rubber, and the outside is made of acid-alkali-resistant and weather-resistant styrene-butadiene rubber. Working pressure, the tube body is suitable for the natural environment where the ambient temperature is -40°C~ 121°C (-40°F~ 250°F).

In order to promote the scientific research of basic knowledge of geological environment in harsh environments such as ultra-deep water wells, high pressure, high damage drilling natural environment, high temperature difference, strong sand and dust, Litong High-tech R & D department based on independent innovation production process and material selection , developed and designed the LT 301F high wear-resistant alkali fracturing plastic hose to meet the needs of its shale oil and gas exploration and development. The German brand UHMWPE is used as the inner plastic hose, and 4~10 layers of coiled extremely soft stainless steel wire or galvanized steel wire rope is used as the pressure-bearing skeleton material.  LT1217 300PSI hot tar bitumen medical dressing delivery pipeline The tube body is used for liposuction and discharge of nicotine and hot bitumen in tankers and trucks below 180°C. The inner structure of the pipeline is made of black nitrile rubber, with very good performance High temperature resistance, high tension stainless steel wire weaving can maintain the pipe body continuously under the premise of working pressure of 300psi. Neoprene is a kind of plastic that is resistant to wear, air oxidation, nitrogen oxides, and fire. It is used to encapsulate the surface of the tube body, which greatly enhances the application characteristics of the tube body.
