Plastic pipelines are used for distribution of demineralised water, chemicals, technological sewage, domestic sewage, cooling water, etc. Plastic pipelines are used for their resistance to chemicals, non-corrosive properties, and tolerance of operation pressures, temperatures and mechanical stress.
Subject to the material used and properties required, plastic pipelines can be connected by gluing, polyfusion, butt welding or with electro fittings. Plastic pipelines for very clean media are welded by IR (Infra red) or balloon (BCF = bead and crevice free) method.
We possess experience in supply and installation of sources and laying of pipelines for ultra pure demineralised water distribution in the semiconductor industry (specific resistance ≥ 18 MΩ.cm). We provide comprehensive supplies of technological subsystems of demi stations including tempering, accumulation, TOC reduction, mixbed filters, filtration (0.2 mm and 0.1 mm), degassing, measurement and regulation, electric power supply. Circulation pipelines for highly purified demineralised water are made of plastic PVDF (polyvinylidene-fluoride) pipes welded by the BCF method.
