I. Overview of corrosion-resistant hoses
Corrosion resistant hoses are pipeline equipment used for transporting corrosive media, with good corrosion resistance and flexibility. It is widely used in industries such as chemical engineering, metallurgy, and power, and is used to transport various corrosive media such as acid, alkali, salt, etc. This article will introduce the raw materials used in the production of corrosion-resistant 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 raw materials used in the production of corrosion-resistant hoses
Inner layer material
The inner layer material of corrosion-resistant hoses is usually made of rubber materials with good corrosion resistance, such as fluororubber or silicone rubber. These materials have good acid and alkali resistance, high temperature resistance, and oil resistance, which can effectively prevent the corrosive effect of the medium on the pipeline.
Reinforcement layer material
The reinforcement layer material of corrosion-resistant hoses is usually made of high-strength materials such as polyester fiber or steel wire woven fabric. These materials have high strength and pressure resistance, which can effectively improve the tensile strength and pressure resistance of pipelines, ensuring their safe operation.
Outer layer material
The outer layer material of corrosion-resistant hoses is usually made of rubber materials such as polyurethane or chloroprene rubber, which have good wear resistance and weather resistance. These materials have good wear resistance and weather resistance, which can effectively extend the service life of pipelines and ensure their safe operation.
V. Conclusion
As a common pipeline equipment, corrosion-resistant hoses require the use of various raw materials in their production, among which the inner layer material, reinforcement layer material, and outer layer material are one of the key raw materials. Consumers need to understand relevant raw material information when choosing and using corrosion-resistant hoses in order to better choose and use products. I hope this article can provide a detailed introduction to the raw materials used in the production of corrosion-resistant hoses, and provide some reference value.
