Giant diameter polyethylene
pipe licence awarded
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 even
individual family-size sewage treatment
units for remote regions. The Weholite
pipe’s smooth surfaces enhance flow
rates compared to steel, cast iron or
concrete. With its extra-large diameters,
Weholite pipe 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.
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.
