Experts for us to explain the little-known hose classification

Hose is a general term for conveying pipes. In order to adapt to the physical and chemical conditions of various industries, hoses usually have very strict implementation standards for chemical raw materials and processes of internal and external colloids. Classified according to working conditions, the common ones are:
1. Welding hose. Used for gas welding, cutting, etc. The inner rubber material is mostly NBR or synthetic rubber, and the outer rubber is usually made of red, blue, yellow, etc. to show special gas.
2. Water delivery hose. Used for irrigation, gardening, construction, fire fighting, equipment and tank truck cleaning, agricultural fertilizer, manure, industrial sewage drainage, etc. The majority of inner rubber materials are PVC and EPDM.
3. Beverage food hose. For non-lipid such as milk, carbonated, orange juice, beer, animal and vegetable oils, drinking water, etc. Inner rubber materials are mostly NR or synthetic rubber. Usually need to have FDA, DVGWA, KTW or CE standard certification.
4. Air hose. Used in compressors, pneumatic devices, mining, construction, etc. NBR, PVC compound, PU, SBR are the majority of the internal adhesive materials. There are usually strict requirements for the applicable pressure.
5. Hot water and steam hose. It is used for cooling water of refrigeration equipment, cold and hot water of engine, food processing, especially hot water and saturated steam in dairy factory. The majority of the inner rubber material is EPDM.
