On January 16, 2020, Hao Huijie, Secretary of the Luohe Municipal Party Committee, Li Jiantao, Standing Committee Member of the Municipal Party Committee, Chairman, Executive Vice Mayor Yu Wei, Li Shechen, Wu Yupei, Deputy Bureau of Luohe Economic Development and Technical Development Bureau, and Zhao Hongliang, the CEO of our company, welcomed me The company browses and investigates the matter. The scientific research elite team first visited the company's showroom. Mr. Zhang described the company's high-end products in detail, such as Hercules, Very Hercules, and API oil series product pipelines. 2. For hoses used to transport strong acid and alkaline media, the residual media should be tidy before cleaning to avoid friction and heat generation during cleaning. 3. There should be no residue in the hose for conveying colloidal medium after application, so as to avoid the reaction of the hose when it is applied next time. You can also use hydrogen, steam or gas to clean the hose, but the ambient temperature should not be too high, and both sides of the hose are open to prevent damage to the hose. So far, the company has 16 high-efficiency patented inventions and has published 6 authorizations. So far, 16 provincial and prefecture-level scientific research projects and 9 provincial and ministerial-level scientific research achievements have been completed. The company is the key technology department for many national standards. The company has 9 national invention patents and more than 20 new patents. Grasp a lot of key technologies in the production and manufacture of hydraulic hoses. In 2017, Litong Automotive Throttle Hose obtained API product quality certification (16C-0403). 150PSI corrugated oil tank pipe This pipe body is mainly formulated for service projects similar to vacuum tanks in oil and gas fields to solve oil, fracturing aqueous solution and slurry, but it is suitable for 35% paraxylene, and the internal structure uses It is a gray-black nitrile-PVC mixed plastic with certain wear resistance, which can effectively achieve oil and gas field applications. The vulcanized rubber used outside has very good wear resistance, air oxidation resistance, and relatively limited wear resistance. The gray-black wave pattern SBR plastic, pipes have good operational flexibility in general. The four-layer steel wire coiled high-pressure high-pressure oil pipe is mainly suitable for the application of crude oil-based gear oil, and is suitable for the working environment of strict standards. In order to ensure that the air-conditioning tube body is in the middle, four layers of steel wire are used to coil the layer to ensure that the tube body can withstand high working pressure. The tube body conforms to the SAE 100R12 specification GB/T10544-2013 standard. In addition, this hose series has an excellent gear oil compatibility mode and has excellent performance. It can be perfectly displayed in the design scheme, manufacturing and other whole processes, as well as the inspection of finished products and other aspects. Food-grade stainless steel hose for liquor industry, FDA certified, the inner rubber layer of general food-grade stainless steel is usually milky white, which makes it easier to distinguish whether the inner layer is dirty. The hose after work is usually cleaned with drinking water. When continuous high-temperature steam is used for disinfection and sterilization, the second work will be carried out later. Disinfectant can also be used to carry out disinfection and sterilization work, and cooperate with water and steam to make the inner cavity of the pipeline more hygienic and safe. To a certain extent, ethanol also has bactericidal effects. But this is not a concrete way of pipe cleaning.
What are the main raw materials used for suction and discharge hoses?
