Composite Chemical Hose Features

1. Multi-layer Construction

The inner layer uses a chemically compatible thermoplastic film.

The middle layer is reinforced with multiple layers of fiber or fabric.

The outer spiral steel wire provides pressure and vacuum resistance.

The outer protective layer (PVC, TPU, or special polymers) enhances abrasion resistance and weather resistance.

This multi-layer protection structure effectively prevents media penetration, improving safety when transporting hazardous chemicals.

2. Excellent Chemical Resistance

Tolerates hundreds of chemicals, including strong acids, strong alkalis, aromatic hydrocarbons, ketones, esters, fuels, and solvents, making it widely applicable in highly corrosive environments.

3. Lightweight & Flexible

30%–50% lighter than comparable rubber chemical tubing, easy to handle, and suitable for frequent movement.

4. Pressure and Torsion Resistance

The inner and outer spiral steel wire structure provides excellent pressure and torsional resistance.

Full vacuum rating optional.

5. Customizable anti-static type composite hose to avoid spark and explosion risks.

What tubing is chemical resistant?

The key to a hose that can safely transport chemicals lies in the fact that its material must be chemically compatible with the chemicals being transported. Below are four common types of chemical-resistant hoses.

1. Thermoplastic Hoses

• PVC (Polyvinyl Chloride) Hoses: Suitable for mildly corrosive aqueous solutions and some weakly acidic or alkaline chemicals. Not resistant to most organic solvents.
• PU (Polyurethane) Hoses: Excellent abrasion resistance, suitable for abrasive powders or slurries, and also resistant to some oils and chemicals.
• PE (Polyethylene) Hoses: Commonly used in food and drinking water applications, and also for some mild chemicals.
• PTFE/PFA Hoses: A versatile material for conveying strong acids and alkalis.

2. Rubber Chemical Hoses

• EPDM (Ethylene Propylene Diene Monomer): Ozone-resistant, weather-resistant, and resistant to phosphate ester hydraulic oils, especially good at conveying polar chemicals (such as ketones, esters, and alcohols).
• FKM/FPM (Fluororubber): High temperature resistant, resistant to various oils and chemicals, with performance close to Teflon, but more expensive.

3. Metal Flexible Hoses

Stainless steel flexible hoses (usually 304 or 316L stainless steel): High strength, high temperature resistance, pressure resistance, vacuum resistance, and good corrosion resistance (especially 316L, which has better pitting resistance).

4. Composite Chemical Flexible Hoses (the most common and efficient choice)

Combining chemical-resistant materials and pressure-resistant metal materials, composite chemical hoses possess multiple superior characteristics such as flexibility, pressure resistance, and chemical resistance, making them the first choice for the chemical and pharmaceutical industries.
