By improving the strength of the production team and introducing advanced production technology, we will continue to upgrade and continuously consolidate the hard power. The company now has 3 external professors/doctoral supervisors and 70 main technical personnel. Our company has 13 invention patents and 9 provincial scientific and technological achievements, especially it has been rated as "Top Ten Hose Enterprises in China". Litong has carried out the O2O promotion model of "online" + "offline", which caters to the current development trend of "Internet +" and sincerely serves new and old customers. Litong products rely on the domestic market to place advertisements in offices and various Internets across the country to expand service areas. Every year, the company invests heavily in the development of new projects such as industrial pipes, rubber and plastic pipes, etc., and continuously improves the quality of products. With its own strength and the achievements of college cooperation, it has established a cooperative relationship with Qingdao University in terms of R&D technology. In addition to close cooperation with many scientific research institutions, it also cooperates with many companies in Germany and the United States to improve products and expand applications. Why sandblasting pipes usually choose rubber pipes, because rubber is highly wear-resistant, more than 10 times more wear-resistant than general PVC dust-absorbing wire telescopic hoses, and rubber pipes are especially suitable for the transportation of dust, powder, fibers, debris and particles , The friction of sand and gravel with high flow rate and very abrasive force will not damage the hose. Therefore, wear-resistant rubber hoses are generally used in normal material transportation and sandblasting and rust removal. On the basis of the original variety of hydraulic hose product clusters, our company has designed and developed over one million pulsed Super Hercules winding series hoses, innovative and upgraded ultra-soft and ultra-high pressure Super Hercules low-bending series hoses, and extreme high-pressure cleaning. The 400MPa ultra-high pressure resin cleaning series hoses preferred by the hose users and the UPE high wear-resistant concrete transportation series hoses that enjoy the reputation of "Anti-Abrasion King", etc. The characteristics and quality of the products have been recognized by domestic and foreign construction machinery users. In addition to the pressure, the volume of the medium passing through it is also one of the important criteria to measure the use of the wear-resistant hose. This requires that the core inner rubber layer of its hose must have excellent wear resistance. Synthetic rubbers such as SBR (styrene-butadiene rubber) and NR (natural rubber) have become the preferred rubbers for wear-resistant hoses. Its wear resistance has been treated by special technology, which can meet the needs of most industries in the market. If the conveying medium contains corrosive substances, be sure to communicate with the manufacturer and carry out special treatment for the inner rubber. Oil drilling and geological drilling are important equipment for drilling. The high-pressure mud hose is used as a flexible connector of the cementing manifold to transport water-based mud, oil-based mud, etc. under high pressure. The conditions are extremely complicated because it has to work in the depths of several kilometers underground. Under the action of stress such as tension, compression, torsion and impact load during operation, the pipe wall is worn by mud and rock particles, and the pipe is required to have sufficient strength, hardness, wear resistance and impact toughness.
