The Caparo Spiral Welded Tube is used
in many applications such as: piling, air
ducts, culverts, general structural steel
work, water, sewage and drainage
systems in the construction industry;
enders and pontoons in marineengineering; wind turbines;
various
architectural applications; grass rollers
in the agricultural sector; and others.
With its distinctive advantages to
longitudinal products, our Spiral
Welded Tube is well known or its
strength, cost eectiveness, wide size
and availability parameters, precision o
manuacture, uniormity and range oancillary items. Manuactured to

Caparo Spiral Welded TubeCaparo oers a huge range o made-to-
order spiral welded tubes, which could
also be supplied with a wide variety o
ancillary items such as stiening bands,
collars, liting lugs, etc. The main benets
o spiral welded tubes are:
Strength. The Caparo Spiral Welded
Tube is welded both internally
and externally providing additionalstrength over tubes with a
single
weld. This prevents breakages and
stretching, especially valuable in
piling applications.
Costeffectiveness.New light
walled Spiral Welded Tube can
oten work out to be cheaper per
unit metre than reusable tube. New
production allows consumers the
opportunity to speciy the exact
wall thickness, minimizing the mass
per metre to that which is actually
required. Flexibility. Spiral Welded Tube oers
greater fexibility in terms o speed o
availability and choice o diameters.
Subject to strip stock any diameter
o tube within the mills capability can
be turned around in a matter o days.
Precision. The continuous process
o manuacturing Spiral Welded
Tube allows the creation o almost
any length without yield loss. This
can be a signicant advantage to
the consumer providing the option
o tailored lengths with resulting lowquantities o waste.
Deliveredtosite.Exact piece
quantities can also be manuactured
and delivered directly to a project
site.
Uniformity.Spiral Welded Tube is
straighter and rounder than the tube
produced rom a longitudinal mill. In
addition, spiral tube manuactured
rom strip will have a more uniorm
thickness than a tube rom ring rolled
plate.
Advantages
Wide steel coils are slit to appropriate
widths and ed into orming rolls or a
orming shoe at a pre-determined angle
to achieve the required tube diameter.
The strip edges are ormed into a
cylindrical shape with edges closely
aligned. The welded joint is made by
the continuous submerged arc process,
employing two welding heads, one inside
and one on the outside. A ull penetration
buttweld, made under optimum
workshop welding conditions, ensures
that a high quality product is consistently
achieved.
Caparo Tubes was one o the rst tube
makers to be accredited with BS 5750:
Part 2 (ISO 9002), which was awarded
to the mills in 1987, and the rst UK tube
mill to attain CE marking.
