Pipe systems for the chemical industry:
reliable, efficient and safe to use

Corrosion causes annual damage amounting to 3% of gross national product (source: WCO World Corrosion Organisation). Plastic pipe systems do not corrode and offer high resistance to aggressive media. They therefore provide high operational reliability, are robust and yet flexible.

The high flexibility of the polyethylene material enables handling and transport of long coiled lengths in ring coils or from a drum. This makes polyethylene pipes ideal for renewal by pulling them into the old pipe. A special renewal option is the use of pre-deformed pipes, which enable trenchless insertion of long lengths even in dimensions up to 500 mm and, during subsequent operation, fit close to the old pipe (close-fit).

Polyethylene is easy and safe to weld. The specifications are established and described in the DVS set of rules. The resulting joints are tensile and permanently leak-tight. This enables safe operation of pressure pipelines even for sensitive or hazardous media.

Plastic pipes are resistant to most chemicals and also hydrocarbons. However, permeation can occur, especially with hydrocarbons. Plastic pipes with barrier layers are therefore ideal for applications that require a permeation-resistant pipe system. A permeation barrier layer reliably prevents pollutants from permeating through the pipe wall in both directions.

Some applications in industry require permanent monitoring for potential leaks in order to protect the environment, and possibly also to comply with legal requirements. This reliably prevents chemical media from escaping into the environment, potential consequential damage to people and nature, and the resulting liability risks. An electrically conductive aluminium layer integrated into the plastic pipe enables 100% leak monitoring for soil and water protection.
