Hose couplings can be used for transporting chemicals, but it is necessary to choose materials and designs suitable for chemical transportation. Due to the wide variety of chemicals, their corrosiveness, temperature requirements, and pressure levels vary, so the characteristics of the chemicals must be considered when selecting hose couplings. Common chemicals such as acids, alkalis, solvents, etc. have higher requirements for the corrosion resistance of materials. Generally, materials that are corrosion-resistant and not easily corroded by chemicals, such as stainless steel, plastics (such as polypropylene and polyvinyl chloride), or special alloy materials, are needed to manufacture hose joints. In addition, the sealing structure of hose joints also needs to adapt to the properties of chemicals to prevent leakage or contamination. Therefore, choosing the appropriate hose connector is crucial for ensuring the safety and reliability of chemical transportation processes.
