manufacture of tubes by the Electric
Resistance Weld (ERW) process entails the
cold bending of steel strip into tubular shape
and welding of the edges together electrically
under pressure. Since the forming in done at ambient
temperature, a very close control on dimensions
and surface finish of the tube is possible.
The Electric Resistance Weld process of tube making
has been used in India for several years, but
mainly for manufacture of commercial quality pipes.
Stelco International manufactures ERW tubes for
use in high temperature and pressure conditions
as well as precision and general engineering applications.
ERW tubes offer many advantages such as tight
tolerance on diameter and thickness, exceptional
concentricity and a smooth finish inside and out.
These features enable designers to obtain uniformity
of flow fabricators can exercise maximum control
of close bending and tube alignment in butt-welding.
No wonder Stelco International's
ERW tubes are extensively used in power and industrial
boilers, transformers, super heaters, economizers,
heat exchangers, bicycles, furniture and automobile
components. Stelco International has contributed
significantly to India's railway electrification
programme by developing special quality ERW tubes
which are used as stay and bracket arms.
Stelco International manufactures
ERW tubes to a variety of Indian and international
specifications. They are certified by leading
The ERW Mill has recently been modernized and
re-equipped to keep pace with improved techniques
and the increasing demand from industry. Stelco
International draws constantly on the expertise
available to stay abreast of the latest developments
in tube technology.
