I. Overview of Industrial Hoses
Industrial hoses are pipeline equipment used for transporting gases, liquids, and other media, widely used in industries, construction, transportation, and other fields. It has good flexibility, pressure resistance, corrosion resistance and other characteristics, and can adapt to working environments with different shapes and bending degrees, making it easy to install and use. This article will introduce the specifications and types of industrial hoses.
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. Detailed explanation of the specifications and types of industrial hoses
Classification based on usage pressure
According to the different pressures used, industrial hoses can be divided into three types: low-pressure, medium pressure, and high-pressure. Among them, the low-pressure type is suitable for low-pressure working conditions, and its working pressure is usually between 0MPa and 10MPa; The medium pressure type is suitable for medium pressure working conditions, and its working pressure is usually between 10MPa and 50MPa; The high-pressure type is suitable for high-pressure working conditions, and its working pressure is usually above 50MPa.
According to material classification
According to the different materials, industrial hoses can be divided into various types such as rubber hoses, polyurethane hoses, PVC hoses, etc. Among them, rubber pipes have good flexibility and corrosion resistance, suitable for transporting chemically corrosive media; Polyurethane pipes have good wear resistance and high temperature resistance, making them suitable for use in high-temperature environments; PVC pipes have good acid, alkali, and oil resistance, and are suitable for use in industries such as chemical engineering.
Classification based on structure
According to the different structures, industrial hoses can be divided into various types such as single-layer pipes, multi-layer pipes, and reinforced pipes. Among them, single-layer pipes are made of one layer of material and are suitable for conveying under low-pressure conditions; Multilayer pipes are composed of multiple layers of materials, which have high strength and pressure resistance, and are suitable for conveying under medium and high pressure conditions; The reinforced pipe has a reinforced layer or steel wire braided layer added inside or outside, which has strong tensile strength and pressure resistance, and is suitable for conveying under high pressure conditions.
V. Conclusion
Industrial hoses, as a common pipeline equipment, have a variety of specifications. Consumers need to understand the relevant specifications and characteristics when choosing, in order to better choose and use products. I hope this article can provide a detailed introduction to the specifications and types of industrial hoses, and provide some reference value.
