In December 2012, it won the title of "famous brand product of Henan Province". Won the "innovative pilot enterprise in Henan Province". The company carries out automobile air conditioning pipe project. On December 10, 2012, the company served as the chairman of the "hydraulic hose product technology innovation alliance" of Luohe branch. At the end of December 2012, the annual sales volume of the company was 128 million yuan. The company invested heavily in the research and development of polymer materials, which have been applied to hydraulic transmission, industrial fluid hose, oil drilling and production hose, FDA food and medicine hose, rubber seal, fluid connector and other materials. High temperature resistant rubber hose has good comprehensive performance. It is mainly used for the lifting and transportation of raw water and sewage, water supply and cooling circulating water of thermal power plant, pipeline transportation of chemical substances in metallurgical industry, condensate water and chemical industry, cooling and dilution in petrochemical industry, flexible connection between long-distance and short-distance pipelines in other industries, etc. On March 8, 2020, women have several identities of daughter, wife and mother. Each identity means softness, but women's identity is not limited to this. In Litong, women are professionals, giving women multiple identities, including daughter, wife and mother.

Working in Litong has no restrictions on the status of women, We pay attention to the development of every woman. I wish you good luck on goddess day, courage and fearlessness. The R4 return pipe has a low-pressure return line with half the bending radius required by SAE j517 100r4, which is suitable for petroleum based hydraulic fluid, water / ethylene glycol and water fire hydraulic fluid, oil, lubricating oil, crude oil, fuel oil and water. The inner part of the pipe is oil resistant synthetic rubber, the outer part is oil resistant, weather resistant and wear-resistant synthetic rubber, and the reinforcing layer is one or two layers of braided fiber and one layer of spiral steel wire. The pipe body has certain flexibility. In addition, the flexibility of the tube can be customized according to customer requirements. Purpose of sand blasting pipe: it is often used for workpiece surface cleaning, such as removing residual sand and high carbon layer on the surface of castings, as well as welds of weldments, eliminating rust and oxide scale. Classification of sand blasting: it is mainly divided into dry spraying and wet spraying. Wet spraying uses abrasive and water to mix into mortar to prevent metal rust, and corrosion inhibitor needs to be added to the water. High dry spraying efficiency, rough processing surface, large dust and many abrasive damage; Wet spraying has little environmental pollution and has a certain effect of decoration and protection on the surface. It is often used in more precise processing. In terms of production technology, the company has been paying attention to excellence, and the company has been committed to technology R & D and innovation. The R & D team and Qingdao University of science and technology established the Rubber Research Institute, strengthened the cooperation between schools and enterprises, adhered to R & D and innovation, continued to launch new products, launched new overall fluid solutions, and established a first-class and perfect service team. Litong will always adhere to the quality policy of "adhering to introduction, digestion, absorption and continuous improvement; adhering to stability, improvement, innovation and meeting customer needs", and adhere to "accumulating good deeds and altruistic thoughts".
