Industrial hose is a kind of pipeline equipment used for conveying various media, with good pressure resistance, corrosion resistance, wear resistance and other properties. It is widely used in industry, construction, transportation and other fields. This article will introduce the main types of industrial hoses.

Ii Domestic standards

 

Gb/t 3683-2001 fabric reinforced rubber and plastic hoses and hose assemblies for hydraulic purposes: this standard specifies the classification, requirements, test methods, inspection rules, marking, packaging, transportation and storage of fabric reinforced rubber and plastic hoses and hose assemblies.

Gb/t 7939-2008 terminology of rubber and plastic hoses and hose assemblies: this standard specifies relevant terms and definitions of rubber and plastic hoses and hose assemblies.

 

2. International standards

 

ISO 14362-1:2014 rubber and plastic hoses - Part 1: General requirements: this standard specifies the general requirements for rubber and plastic hoses, including materials, structure, dimensions, marking, test methods, etc.

ISO 14362-2:2014 rubber and plastics hoses - Part 2: wire braided reinforced hoses: this standard specifies the requirements, test methods, inspection rules and other aspects of wire braided reinforced hoses.

 

3. Specification and type of industrial hose

 

According to different use requirements, industrial hoses are generally divided into the following types:

Low pressure type: low pressure type hose is mainly used under low pressure conditions, and its working pressure is usually between 0mpa and 10MPa. Common low-pressure hoses include PVC hoses, polyurethane hoses, etc.

Medium pressure type: the medium pressure type hose is mainly used under medium pressure conditions, and its working pressure is usually between 10MPa and 50MPa. Common medium pressure hoses include nitrile rubber hoses, neoprene hoses, etc.

High pressure type: high pressure type hose is mainly used under high pressure conditions, and its working pressure is usually above 50MPa. Common high-pressure hoses include steel wire braided reinforced hose, nylon reinforced polyurethane hose, etc.

 

4. Conclusion

 

The specification and type of industrial hose is one of the important indicators to measure its performance. Consumers need to understand the relevant standard requirements when choosing, and pay attention to check whether it meets the relevant standard requirements. It is hoped that this paper can provide some reference value for the main types of industrial hoses.
