A Shaanxi Engineering Equipment Co., Ltd. has long-term production of sandblasting machine, shotcrete machine and its accessories, involving sandblasting, material spraying and other equipment. The shotcrete pipe produced by the company can sand blast concrete up to 100000 m3 and supply wear-resistant materials. The company produces wear-resistant sand blasting pipe with ultra long wear-resistant life, which has been recognized by the company and users. We have reached a long-term cooperative relationship with the company. The company supplies 10000 meters of sandblasting pipe every year, which is applied to sandblasting machine, shotcrete machine, mixing plant and other equipment. The products have excellent wear resistance and have been highly praised by customers. Litong hose is widely used in the chemical industry, and corrosion resistance of hose is required in many application scenarios. Through the efforts of Litong family, we finally developed PTFE rubber plastic composite multi-functional hose, which can transport high-strength corrosive chemicals at high temperature, which can not be achieved by many manufacturers. The service life of the hose is very low in the corrosive environment, but Litong's hose adds special materials and uses ingenious technology to transport all kinds of chemical substances. The fire prevention certificate of Lloyd's register of shipping of Litong products has successfully proved the excellent performance of Litong products, indicating that the industrial technology level of our products has reached the world-class level, further expanding the structure of Litong products. The company's product department has entered the international ship, oil drilling and other departments are opening up a broader market, which also marks that Litong manufacturing has entered a new stage of high-quality development in the international market. Nowadays, the amount of oil exploitation is in short supply, and high-quality and wear-resistant oil hoses are needed; With the high-end scientific and technological achievements independently developed by Litong technology - lt301f super wear-resistant hydraulic & acidizing fracturing hose, Litong technology has become a hose manufacturer of oil drilling and production equipment that has attracted much attention at the exhibition. Lt301f has become one of the few ultra-high pressure acidizing fracturing hoses specially developed for efficient and safe exploitation of deep oil and gas resources in the world. In March 2018, the bonding of PTFE rubber was successfully realized. This technological breakthrough not only solved the core separation defect of PTFE pipe body in application, but also opened up more application fields, making Teflon hose perfectly applied in many fields such as chemistry, medicine, food and chemical industry. This not only reflects the exquisite technology of Litong hydraulic in rubber pipe technology, but also realizes a milestone breakthrough in rubber development, It has become the first manufacturer in the world to realize the bonding of PTFE materials. The main source of the safety problem of using high-pressure water to clean the hydraulic system is the internal cleaning of the hydraulic pipe. Due to the limitations of the production process, there are already debris and other substances in the production process of the rubber pipe. During the production of the rubber pipe assembly, the colloidal debris generated by cutting will also be the main problem affecting the cleanness of the inner wall of the hydraulic rubber pipe assembly. At present, the ultra-high-pressure water cleaning hose produced by Luohe Litong hydraulic uses ultra-high-pressure water to wash the inner wall, The effect is very good. It is recommended to use it.
