The KWH Pipe Ltd. Group of Vaasa, Finland and Armco Staco S.A Industria Metalurgica of Rio de Janeiro, Brazil have announced the granting by KWH Pipe to Armco Staco of an exclusive license for the manufacture and marketing of Weholite Pipe in Brazil. The Weholite product line, invented by KWH Pipe in the 1980s, consists of  High Density Polyethylene Pipe, Fittings and fabricated assemblies.

Alstom has now used polyethylene piping instead of concrete in a power station’s cooling water intake for the first time. The advantages of polyethylene piping are that it is easy to install on the sea floor and has a life expectancy of at least 50 years in salt water compared to about -25 years for certain concrete pipes. The gas-powered combined cycle power plant was built in Fos-sur-Mer in southern France by CyCoFos, a power company that is a subsidiary of Gaz de France.

Scottish Water, the fourth largest water and wastewater services provider in the UK, has teamed up with engineering, consulting and construction company Black & Veatch and piping solutions providers KWH Pipe to employ an innovative concept of mobile pipe production that will reduce costs and environmental impact in a project to upgrade Edinburgh’s water treatment facilities.
