Giant diameter polyethylene pipe licence awarded

Armco Staco, with operations in Brazil in Rio de Janeiro, São Paulo, Jacarei and Resende, claims to be the largest manufacturer of corrugated steel drainage pipe and highway safety steel guard rails in Latin America. Weholite production operations for Armco Staco will be carried out at newly constructed facilities now underway at Resende, Brazil. Weholite product is expected to be available from Armco Staco during the second half of 2013.

also provides an enclosed channel to conduct liquids over some distance. The lightweight polyethylene pipe is continuously extruded and thus furnished in any shippable length, which facilitates quick installation. Its corrosion resistant properties ensure long service life. Weholite pipe is joined mostly by extrusion welding, and the joints meet the standards for leak-proof joints. KWH Weholite licensees have manufacturing operations in nine other locations in Europe, Asia, Africa and Latin America in addition to KWH Pipe direct owned factories in Finland, Nordic countries, Europe, North America and Asia. KWH Pipe has been producing plastic pipe since 1955, and also manufactures solid wall HDPE pressure pipe up to 1,600mm outside diameter.

The KWH Pipe Ltd Group, Finland, and Armco Staco SA Industria Metalurgica, Brazil, have announced the granting by KWH Pipe to Armco Staco of an exclusive licence 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. Among the features of the structured wall HDPE Weholite pipe is its availability in inside diameters up to 3,500mm. Armco Staco plans initial offering up to 3,000mm ID. The pipe is used in low pressure/gravity service applications with potable water, storm water, sewage and various other liquids. Weholite fabricated assemblies are designed for special functions such as manholes, detention tanks and
