large diameter pipe
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.

SAWL and SAWH pipes
The Europipe Group has four production
sites in both Europe (Germany and
France) and the USA (Florida and
Alabama), annually producing over
3,000km of longitudinally and helically
submerged arc welded large diameter
pipe for pipeline projects around the
world.
The outside diameters of SAWL
large-diameter pipes range from 508
to 1,524mm (20" to 60"), with wall
thicknesses of 7 to 45mm and lengths
of up to 18m (60ft). In SAWH execution,
the OD ranges from 610 to 1,422mm
(24" to 56") with wall thicknesses of
8 to 20mm and lengths of up to 24m
(80ft).
Europipe is a main pipe supplier for
ultra-large projects, such as the Nord
Stream Pipeline I + II, Baltic Sea, for
which Europipe delivered a quantity of
1,800km; and Ichthys, Australia (540km).
Europipe can supply high-strength pipe
from X80 to X100; HIC-resistant pipe in
all grades up to X70; collapse-resistant
pipe with optimisation of geometry and
grade; and Arctic-grade pipe.
Respect for the environment, protection
of the health and safety of its employees,
and the use of resource-conserving
methods of production are important
to Europipe, and the company is
accordingly certified to the ISO 14001
and OHSAS 18001 standards.
