The 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.
Stelco International's 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 inspection bodies.
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.
