What are the specifications and models of hoses used in the marine shipbuilding industry?

 

The hose used in the marine shipbuilding industry is a type of pipeline equipment used to transport various media, with good pressure resistance, corrosion resistance, wear resistance and other properties. It is widely used in various systems and equipment on ships, such as hydraulic systems, cooling systems, fuel systems, etc. This article will introduce the specifications and models of hoses used in the marine shipbuilding industry.

 

II Domestic standards

 

GB/T 3683-2001 "Rubber and plastic hoses and hose assemblies - Fabric reinforced 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 for Rubber and Plastic Hoses and hose assemblies: This standard specifies the relevant terms and definitions for rubber and plastic hoses and hose assemblies.

 

III. 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, testing methods, and other aspects.

ISO 14362-2:2014 "Rubber and plastic hoses - Part 2: Steel wire braided reinforced hoses": This standard specifies the requirements, test methods, inspection rules, and other aspects of steel wire braided reinforced hoses.

 

IV. Specification and model of hoses in the marine shipbuilding industry

 

According to different usage requirements, hoses used in the marine shipbuilding industry are usually divided into the following specifications and models:

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

Medium pressure type: Medium pressure hoses are mainly used under medium pressure conditions, and their working pressure is usually between 10MPa and 50MPa. Common medium pressure hoses include nitrile rubber hoses, chloroprene rubber hoses, etc.

High pressure type: High pressure hoses are mainly used under high pressure conditions, and their working pressure is usually above 50MPa. Common high-pressure hoses include wire woven reinforced hoses, nylon reinforced polyurethane hoses, etc.

 

V. Conclusion

 

The specifications and models of hoses used in the marine shipbuilding industry are one of the important indicators to measure their performance. Consumers need to understand the relevant standard requirements when choosing, and pay attention to checking whether they meet the relevant standard requirements. I hope this article can provide some reference value for the specifications and models of hoses used in the marine shipbuilding industry.
