The use of thermoplastic materials in the chemical industry has developed a new technology for the handling of polypropylene lining material in chemical aggressive media related to gas scrubbers. This new installation technology was based on developing a lining system, which are large size thermoplastic sheets made out of polypropylene with a thickness of 5 to 8 mm. One side of the sheets is provided with a defined number of conical anchor studs which creates an inseparable mechanical bond with the concrete. This lining system offers chemical, thermal, mechanical and abrasion resistance properties. The utilization of polypropylene pipes main advantage is that this material does not require additional corrosion protection and prevents the formation of deposits or incrustation. Thermoplastic materials are used for spray systems against severe chemical and mechanical loads.

Polypropylene is abrasion resistant and can be utilized consistently as a lining material as well as material for structural elements, particularly in flue gas scrubbers, were high service life can be anticipated
