Filler is a main raw material of rubber and can be composed of many materials. Now there are many kinds on the market, but they are all varied. In recent years, Letone has continuously improved the surface technology of inorganic fillers. Through research and practical application, we have produced inorganic fillers with low price and superior quality, providing technical support for the use of inorganic fillers in the hose industry, making the hose magnetic and conductive. properties, so that the hose has better processing performance. The unique molecular structure and performance characteristics of EPDM endows EPDM with excellent heat resistance, ozone resistance and aging resistance. It can be used for a short time or intermittently at ℃, and the use temperature range can be further increased by the reasonable combination of ingredients. Therefore, EPDM rubber is generally selected for high-temperature-resistant steam hoses on the market at present, to ensure that the steam hose can be used normally under high temperature conditions. The company is committed to the innovation of marketing layout. 

   Letone has established 18 offices in the domestic mainland market, and established a service center to provide customers with technical and after-sales services. From pre-sale to mid-sale to after-sale, it can satisfy the purchase and technical services of customers all over the country. Letone has established a good national sales network several times, and the company has established a perfect after-sales service system. As long as there are product quality problems, it can deal with the problems in time. The company has more than 40 professional CNC lathes, 5 German Uniflex seaming machines, 4 three-dimensional pipe bending machines, 1 carbon and sulfur analyzer, 1 salt spray testing machine, 1 BIMAL high-voltage pulse test bench, material hardness testing Instruments, image measuring instruments and more than 50 other supporting production equipment. Professional equipment provides great convenience for the company’s production and greatly improves production efficiency.   The oil hose is buried underground, which inevitably makes the pipeline subject to soil corrosion. The corrosion caused by the soil medium is mostly electrochemical corrosion, and there are many factors that affect soil corrosion. The main influencing factors in the deep burial of pipelines are soil resistivity, reduction potential and salt content. In addition, groundwater and air The content, temperature and acidity will also cause corrosion of the pipeline. In order to realize the research and development and breakthrough of key technologies, assist the development of unconventional oil and gas resources at home and abroad, and achieve high and sustained and stable production of oil and gas fields, as one of the earliest domestic enterprises to carry out localization and large-diameter oil pipeline technology, Litong Technology closely follows the shale oil and gas technology. The new trend of revolution, adhere to the road of independent innovation. Litong Technology strives to break the “stuck neck” problem of key technologies at home and abroad, improve R&D and efficiency, and participate in and undertake two major scientific and technological projects in Henan Province, including “H2S-resistant pulse-resistant ultra-high pressure oil drilling and transportation hose” project.
