In 2013, Litong Testing Center was awarded the title of High Pressure Hose Technology Research Center by Henan Provincial Department of Science and Technology. In July 2016, Litong Testing Center was the first professional rubber hose R&D center in China that officially obtained the laboratory accreditation certificate issued by the China National Conformity Assessment Agency (CNAS). This certificate confirms the testability of Litong vulcanized rubber and rubber hose, indicating that Litong is qualified to test and evaluate the quality of vulcanized rubber and rubber hose, and the inspection results are fair, accurate and authorized. In December 2019, the company's technology center was identified as the enterprise technology center of Henan Province. Henan Enterprise Technology Center is organized and evaluated by the Henan Provincial Development and Reform Commission in cooperation with relevant departments. The evaluation criteria include economic and technological strength, economic advantages, industry advantages, technological competitive advantages, R&D test conditions, availability of independent intellectual property rights, basic technology, etc. It is the global embodiment of the company's research and development strength, and the company's technological innovation and research and development capabilities. Under the same conditions of pressure resistance, the oil hose is better than the rubber hose of the same specification. It can still work normally under a small radius of gyration, and its bending parts are always round, and will never fold, fall off the inner wall, block and break the tube. Due to the use of laminated galvanized sheet structure, it has good pressure resistance, and the hose will expand and contract when charging and decompressing. Mainly used in oil exploration, oil refining and so on. With the increasing use of high-pressure steam car washing machines, the consumption of braided steel wires and external braided wires in high-temperature resistant high-pressure steam hoses is increasing. Connectors are stainless steel. The outer braided wire acts as heat insulation. Plus a rubber cover. In the past, many oil refineries purchased high-pressure steam hoses with cloth-covered steam hoses, which had a very short service life and were very bad for the environment. There were many recycling and reuse links for rubber hoses. Many people know that wear-resistant sandblasting pipes are a typical representative of wear-resistant rubber hoses. Wear-resistant rubber hoses are mainly used to transport particulate media, such as power plant transportation of pulverized coal, mine dust removal, dredger suction and discharge, mud transportation for construction, machinery and equipment. Rust removal, sandblasting, etc.; the inner diameter of the wear-resistant sandblasting pipe ranges from 5 mm to 1200 mm according to the application, and the pressure range varies. At this stage, our company is mainly engaged in the production and research and development of high and low pressure rubber hoses, drilling hoses, cloth hoses, sandblasting hoses, rubber hose and belt products, and other products. The total investment of the Litongtong Fluid Technology Intelligent Industrial Park project is as high as 1.65 billion yuan. And on the basis of the current development, it plans to invest 1.35 billion yuan to build 90 rubber pipe composite production lines, adding an annual output of 105 million meters and creating an annual production capacity. 120 million meters of rubber composite hose technical field industrial park. The new project is divided into two phases with a construction period of 3 years.
