Chemical Suction And Discharge Hose

Rubber chemical hose is a tubular rubber product specially used for conveying various chemical media. It has good corrosion resistance, flexibility and sealing properties and is widely used in chemical, petroleum, pharmaceutical, food and other industries.

1. Excellent chemical corrosion resistance: The inner rubber layer is made of specially formulated rubber materials, such as EPDM (ethylene propylene diene monomer rubber), NBR (nitrile rubber), FKM (fluoro rubber), etc., which can resist the erosion of a variety of strong acids, strong alkalis, organic solvents, chlorides, oxides and other chemicals, and can transport more than 98% of chemical substances. 2. Good mechanical properties: The middle reinforcement layer is made of high-strength fiber braided mesh, spiral steel wire or polyester cord and other materials, which give the hose high compressive strength and explosion resistance, can withstand strong working pressure, and ensure that there will be no rupture or leakage during the transportation of chemical media. 3. Excellent flexibility: The rubber material itself has good elasticity and flexibility, so that the chemical hose can be easily bent, adapt to various complex pipeline layouts and usage scenarios, and facilitate installation and operation. 4. Antistatic performance: The inner and outer layers of some rubber chemical hoses are made of antistatic materials, which can effectively prevent static electricity accumulation when transporting high-resistance fluids, reduce the safety risks caused by static electricity, and ensure safe use. 5. Smooth inner wall: The inner rubber layer has a smooth surface, which can not only reduce the resistance of chemical media when flowing in the pipe, ensure the conveying efficiency, but also be easy to clean, avoid chemical residues, and prevent cross contamination. 6. Aging and wear resistance: The outer rubber layer has aging resistance, UV resistance, ozone resistance and other properties, and can be used for a long time under different environmental conditions, and is not prone to aging phenomena such as cracking, hardening, and fading; at the same time, the outer rubber layer also has good wear resistance, which can resist friction and scratches from external objects and extend the service life of the hose

Inner rubber layer : directly in contact with chemical media, chemically resistant rubber materials are selected, such as EPDM for acid and alkali resistance, NBR for oil and some organic solvents, and FKM for a wider range of chemical resistance, capable of withstanding strong acids, strong alkalis, strong oxidants, etc. Reinforcement layer : usually composed of high-strength fiber braided mesh, spiral steel wire or polyester cord, etc., to provide strength and pressure resistance for the hose, so that it can withstand the pressure during transportation. Outer rubber layer : mainly plays a protective role, preventing the inner rubber layer and reinforcement layer from being affected by the external environment, such as ultraviolet rays, ozone, wear, etc., generally using rubber materials with aging resistance, wear resistance, weather resistance and other properties.

☆Chemical industry : used to transport various chemical raw materials, intermediates, finished products, etc., such as sulfuric acid, hydrochloric acid, sodium hydroxide, benzene, toluene, xylene and other organic solvents. ☆Petroleum industry : in the process of oil extraction, refining and transportation, it can be used to transport crude oil, finished oil, lubricating oil, drilling fluid and other media. ☆Pharmaceutical industry : suitable for transporting various high-purity chemicals, liquid medicines, solvents, etc. in the pharmaceutical process to ensure that the quality of medicines is not contaminated. ☆Food and beverage industry : can be used to transport food raw materials, additives, fruit juices, alcohol, edible oil, etc., and rubber chemical hoses that meet food-grade hygiene standards can ensure food safety and hygiene. ☆New energy industry : for example, it plays an important role in the transportation of new energy battery slurry, meeting the requirements of the new energy industry for the transportation of chemical media
