Multifunctional chemical hose refers to the hose with good corrosion resistance to strong solvents and strong acid and alkali media, which can be used to transport almost all known chemical products such as benzene [toluene, xylene] ketone [butanone, acetone, cyclohexanone] ester [butyl ester, ethyl ester], alcohol, aldehyde, hydrocarbon, acid, alkali, chlorinated hydrocarbon, etc. Solvent hoses are widely used for conveying and discharging paints, dyes, inks, coatings, chemical additives and benzophenone organic solvents in the production process of chemical industry, paint, coating and ink industry. Storage and transportation of highly corrosive chemicals such as solvents, acids and alkalis in filling trucks, barges, docks or storage tanks in the chemical industry; Printing and packaging industry transports ink (oily ink and water-based ink).
Hose for hydraulic braking
Uses: used in various engineering buildings, including transportation, injection molding, agricultural machinery, metallurgy = forging, mining equipment, ships,
Machine tool, used for conveying high-pressure liquid and hydraulic transmission in various mechanization and automation systems at the first stage. The hydraulic hose of the futures general tool is mainly used for various manual and electric hydraulic jacks or similar tools to transmit pressure sources. Applicable media are hydraulic oil, fuel oil, first-class water of lubricating oil, air and water-based liquid (except castor oil and fat-based liquid). The medium temperature is -40℃-+ 100℃ for oil and -30℃-+50℃ for air.
High pressure hydraulic rubber hose
coal industry
The tubing used in coal industry mainly includes hydraulic support hose. The pressure requirements of some coal mine hydraulic supports have been improved, and some steel wire braided hoses can not meet their performance requirements, so it is required to use steel wire wound tubing instead. In addition, in order to prevent coal dust pollution during underground mining and improve production safety, the varieties of oil pipes used in coal mines have been increased, such as the telescopic oil pipes of coal seam water seal borers, which are used for coal seam water injection and grouting before fully mechanized mining in coal mines. It is reported that it has been produced by domestic manufacturers and tried by more than a dozen coal mines, which can replace similar imported products.
oil industry
In the 20th century, China's offshore oil development strategy proposed to focus on developing offshore and shallow-sea oil fields. Therefore, in addition to drilling tubing and vibrating tubing, the oil industry also requires the use of shallow water oil pipelines. China has produced shallow sea submarine oil pipelines, but floating or semi-floating oil pipelines and deep sea submarine oil pipelines still rely on imports. With the implementation of China's offshore oil development strategy, the requirements of offshore oil exploitation for tubing performance will be continuously improved.
metallurgical industry
The equipment used in iron and steel production process includes continuous casting equipment, which is divided into electric furnace converter and hot furnace converter. Among them, the requirement of rubber hose is that it must be armored to keep warm, reduce temperature and resist fire. In the use of oil pumps and pumping stations, in addition to qualified pressure, it is also required to meet the requirements, that is, aging resistance.
irrigation and water conservancy
Document No.1 of the Twelfth Five-Year Plan put water conservancy on the bill and passed it, and invested10 billion yuan for reform. Among them, in the process of water delivery, especially in the case of negative pressure, skeleton high-pressure hose has shown its own advantages, long service life and convenient carrying.
