Anti-spark PU hoses

Spark erosion-protected PU hoses - safety in sensitive environments

Spark-erosion protected PU hoses are specially developed for use in environments where flying sparks and electrical discharges can occur. Made from thermoplastic polymer - polyurethane (PU) - these hoses on reels offer a length of 25 meters.

Applications for PU hoses with spark erosion protection

These hoses are primarily used in flammable environments, such as when handling flammable gases, liquids, vapors or dusts. They are used in the oil and gas industry, in the chemical industry as well as in the aerospace and automotive industries.

Functioning of the spark erosion protection

Spark erosion-protected PU hoses are equipped with special conductive materials that are incorporated into the polyurethane or integrated as layers. The inner layer of PU forms a protective barrier for the transported materials, while the conductive material lies on top. Reinforcements such as fabric and wire mesh provide additional stability.

Advantages of PU hoses with spark erosion protection

• Safety: Reduction of fire and explosion hazards.
• Protection: Minimizes the risk of damage from flying sparks and electrical charges. These hoses are also chemically resistant.
• Durability: Robust construction for long-term use.
• Temperature resistance: Application ranges from -40 °C to +70 °C.

Selection criteria for PU hoses with spark erosion protection

Several factors should be taken into account when making your choice:

• Working pressure: Typically five to twelve bar.
• Diameter: Inner diameters of four to eight millimetres and outer diameters of six to twelve millimetres are available.
• Chemical resistance: Resistance to oils, fats, acids, heat, bases, ageing and UV light is crucial.
