Chemical Hose Manufacturer

A chemical hose can deliver various kinds of chemicals, liquids, and solvents safely and efficiently. It is made of flexible EPDM material to ensure no leakage or chemical reactions are caused.

Common uses of inner tube materials of industrial chemical hoses include UHMWPE, PTFE, FEP, and Viton.

UHMWPE (Ultra-High-Molecular-Weight Polyethylene) is a corrosion-resistant material commonly used in the chemical industry. It withstands low temperatures and is suitable for conveying media containing solid particles, such as silt, mineral slurries, and wastewater.

PTFE offers excellent chemical corrosion resistance and is suitable for conveying highly corrosive media, including strong acids, strong alkalis, and potent organic solvents. It operates stably in both low- and high-temperature environments; with its smooth inner wall and good flexibility, it is an ideal choice for the chemical, food, and pharmaceutical industries.

Another material is fluoroelastomer (FKM/FPM), a synthetic rubber containing fluorine atoms. It boasts excellent resistance to corrosion, high temperatures, and aging. Consequently, it is frequently used to convey media such as gasoline, diesel, acids, alkalis, fuels, and organic solvents.

The materials mentioned above are resistant to strong corrosion. Materials resistant to mild corrosion include neoprene, EPDM, NBR (nitrile rubber), and polyurethane. For media such as dilute sulfuric acid, water, or alcohols, EPDM is the preferred choice. For media such as petroleum products, hydraulic oil, or mineral oil, NBR or neoprene materials are preferred.

Our chemical hose fittings are primarily made of two materials: stainless steel and PP (polypropylene).

Stainless steel fittings are the most common type on the market. They offer excellent resistance to acids, alkalis, and corrosion, ensuring no rusting occurs during the long-term transport of chemical media. Stainless steel is highly rigid, resistant to deformation during installation, structurally stable, and offers a longer service life.

PP (polypropylene) is used in normal-temperature, low-pressure environments and in highly corrosive chemical environments. PP is lightweight, making installation easier.

1. Confirm the name, composition, and particle content of the chemical substance being conveyed.

2. Consider the operating environment and ambient temperature.

3. Ensure the hose's working pressure exceeds the system pressure.

4. Determine the application: chemical transfer hose vs. chemical suction and discharge hose.

5. Special features: anti-static design.

6. Compliance with relevant chemical hose standards.

At Rentone, we use the STAMPED selection method to help you choose the correct chemical hose. The seven letters stand for: S (Size), T (Temperature), A (Application), M (Media), P (Pressure), E (End Connections), and D (Delivery).

UHMWPE chemical hoses outperform PTFE in terms of flexibility, abrasion resistance, and overall cost-effectiveness.

UHMWPE is 3-5 times more abrasion-resistant than PTFE and will not crack even with frequent dragging. PTFE has relatively weak abrasion resistance and is prone to wear and leakage in rough surface environments.

Compared to PTFE, UHMWPE has superior flexibility, making it easier to bend and handle during installation. It is also lighter and easier to transport.

UHMWPE hoses feature an embedded spiral steel wire. Even in a full vacuum environment, it will not deform or collapse, truly achieving bidirectional operation of negative-pressure suction and positive-pressure conveying.
