With the long-term steady growth of my country's economy and the rapid growth of the right to use automobiles, the demand for oil continues to grow rapidly. The rapid growth of oil demand has created a large sales market demand for high-pressure wear-resistant hoses for oil drilling. The oil drills manufactured by our company use special high-pressure wear-resistant hoses, and have the API7K, API16D and other qualification certificates given by foreign petroleum science (API), which are reliable choices for oil drilling and production. The market positioning is high-end, and the company is devoted to the development and production of new products in the high-end rubber hose industry. It is the largest and most complete product in my country so far. The products cover the sales market of medium and high-end hoses, and industrial production hoses should be sold. Market, used in, chemical plants, pharmaceuticals, food, smelters, construction machinery and equipment, etc., multi-industry and other commodity sales markets. In 2019, continuous capital investment was introduced to introduce professional production equipment and test equipment, and in the face of high-end products, we persisted in independent innovation. At the production process level, we have always paid attention to meticulous craftsmanship, and the company has been focusing on technical product development and independent innovation. The R&D department and Qingdao University of Science and Technology set up a plastics research laboratory, strengthen school-enterprise cooperation and collaboration, persevere in product development and independent innovation, continuously release new products, release new overall solutions for liquids, and create a first-class and sound business elite team. Litong will always adhere to the quality goal of "persistently introducing, digesting and absorbing, absorbing, and continuously improving; persistently stable, improving, independent innovation, and meeting customer needs", and persistently "accumulating good deeds and altruistic concepts". Polytetrafluoroethylene [PTFE] is one of the best raw materials for corrosion resistance in today's society, so it has the reputation of "the king of plastics". It can be used in all types of organic chemicals for a long time Product production and processing. Compared with other plastics, PTFE has excellent solvent resistance and high temperature resistance, and it has been widely used as rubber seals and supplementary materials. 2. Assemble the connector according to the manufacturing instructions. Check the firmness of the joint according to the use of each steel pipe. 3. It is not necessary to bend too many pipes close to a part of the connecting head. 4. When not used, use a scientific and reasonable method to store the pipeline. 5. Put it on the iron shelf or on the tray to minimize the damage of the pipeline in storage. 6. It is not necessary to hang the pipeline on hooks or nails, or other equipment that is likely to damage the pipeline. The R&D department and Qingdao University of Science and Technology set up a plastic research laboratory, strengthen school-enterprise cooperation and synergy, persevere in product development and independent innovation, scientific research results are competitiveness, endless research conclusions and new technology applications, the introduction of French Mayer excellent wire wrapping packaging There are 10 sets of machines and 20 sets of excellent steel wire rubber hose weaving machines. The company persists in the initial and leading product research and development strategies, and continues to develop assassin-level products, whose main uses range from construction machinery and equipment to national defense machinery and equipment, wind power generation, railway transportation, chemical plants, petroleum, pharmaceuticals, food and other industries .
