GRP Piping Systems

Since 1969, Plasticon Composites has enjoyed a worldwide reputation in glass fibre reinforced (GRP) pipes and fittings with its Kialite® brand and Plastilon® brand (bell & spigot bonding system) GRP piping systems. Today, GRP piping systems are available in a variety of standard diameters ranging from 25 to 1200 mm. Plasticon Composites offers GRP pipe and fittings to meet all national and international standards depending on the area and application. Combining the strength of GRP and the chemical compatibility of plastics provides customers with a superior alternative to costly metal alloys and rubber-lined steel.

Dual Laminate Piping Systems

In addition, Plasticon Composites manufactures and installs thermoplastic lined GRP (dual laminate) pipes for aggressive products such as chlorine gas, hydrochloric acid, sodium hypochlorite and caustic soda. Various thermoplastic and fluoropolymer liners were combined by Plasticon Composites (PVC, C-PVC, PP, PE, PVDF, E-CTFE, FEP, PFA, MFA) with glass fibre reinforced polyester resins to provide customers with dual laminate piping systems for extremely hot and corrosive environments.

Application Areas

Due to their excellent properties, Plasticon Composites GRP or Dual Laminate piping systems can be used perfectly in several environments. These include all kinds of underground piping systems designed according to ISO 14692 and AWWA 45. Plasticon Composites can also supply insulated piping systems for cooled water conduits used in tropical and subtropical regions or in cold environments. These include heat tracing to prevent the medium from freezing. The use of polyurethane insulation finished with a GRP laminate ensures 100% vapour-tight insulation. Plasticon Composites can comply with any requirements relating to product identification.
