Nexans Deutschland GmbH is the
manufacturer of a new universal welding
machine, branded the Uniwema ®650.
This machine is capable of manufacturing
corrugated stainless steel pipes up to
an OD of 650mm and a wall thickness
of 3mm. Prior to the development of this
machine, the biggest Uniwema machine
was limited to an OD of 400mm.
The new machine was designed as a
solution to today’s onshore and offshore
LNG (liquefied natural gas) transfer and
terminal applications. The LNG industry
requires vacuum-insulated, flexible,
stainless steel pipes with an outer diameter
of up to 16". Environmental and safety
aspects currently play the most important
role in the increasingly sensitive LNG
market.
The well-proven technology of the
split clamp caterpillar capstan – in
combination with the Uniwema corrugation
technology – will be used for this world
biggest continuous forming, welding and
corrugating machine. Nexans is in the
position to deliver any length of corrugated
pipe systems up to an ID of 600mm.
Depending on transportation restrictions,
a typical length of one pipe section is from
55m up to 350m. The drive system of the
split clamp caterpillar capstan comes
in the form of a hydraulic system, while
the electrically driven corrugation unit is
synchronized to the capstan speed.
Welding is performed through the
company’s patented and ASME approved
Polyarc process.
Multimetals Limited is a manufacturer
and exporter of seamless extruded drawn
copper and copper alloy tubes. The
company supplies applications including
heat exchangers, nuclear and thermal
power plants, shipbuilding and repairs,
petroleum refineries, sugar plants, defence
establishments, and air conditioning and
refrigeration.
The product range includes tube and pipe
manufactured from copper, capillary, cupro-
nickel, admiralty brass, aluminium brass and
other brasses, together with bare, low fin
and U-bend tubes. Other products include
copper-alloy rods, profiles and alloys such
as aluminium and manganese bronze, naval
brass, cadmium and tellurium copper.
The company, which exports to all developed
countries, has won 11 Indian export
excellence awards in the last 13 years.

while the cutting process is constructed
from two combined electrical axes, as with
other milling-machines.
The cold saw can be operated either by
HSS or TCT blades, as in the whole range
of MTM flying cut-off machines. There is
no gap between the two blades, due to a
reduced blade diameter.
The Comby models allow high productivity
and low running costs whenever burr-free
cutting is necessary.
The first Comby units are already operating
with excellent results.
