In today’s society, rubber hoses have become an indispensable part of the industrial field. Whether it is production, processing, storage or transportation, rubber hoses are an important link connecting all links. As a mature technology, rubber hoses for transporting chemicals are gradually attracting attention from all walks of life. However, choosing the right rubber hose to transport chemicals can be difficult. A variety of factors need to be considered. This article will give you a detailed analysis of what factors are more important when choosing rubber hoses for chemical transportation and help you make a wise choice.
Materials and features of rubber hoses
The material of rubber hose is one of the important factors when choosing chemical transportation. Different rubber materials are suitable for different chemicals, so it is necessary to select the appropriate rubber material according to the specific application scenario.
Ethylene propylene diene rubber (EPDM)
EPDM rubber is a general-purpose rubber that is resistant to temperature and aging. It has excellent weather resistance, ozone resistance and high temperature resistance, and can be used in a wide temperature range. It also has good electrical insulation properties and chemical corrosion resistance.
Nitrile rubber (NBR)
Nitrile rubber is a general-purpose rubber that is resistant to temperature, aging and grease. Has good oil resistance, solvent resistance, abrasion resistance and heat resistance. It has good resistance to most greases, fuels and solvents, but is not resistant to strong acids and alkalis.
Ultra high molecular polyethylene (UPE)
Ultra-high molecular polyethylene is a polymer material that is resistant to weak acid and alkali, temperature and aging. It has extremely high molecular weight and excellent wear resistance and can be used at higher temperatures. It also has good chemical and weather resistance.
Teflon (PTFE)
Teflon is a composite material that is resistant to most strong acids and alkalis, temperature and grease. It has excellent high temperature resistance and can be used in a wide temperature range. It also has excellent grease resistance, chemical corrosion resistance and low friction coefficient. The pipe wall is smooth and the resistance is small when materials pass through.
Therefore, when selecting rubber pipes for chemical transportation, it is necessary to select appropriate rubber materials according to specific application scenarios to ensure the chemical resistance and service life of the rubber pipes.
