Tube Products of India was established in collaboration with Tube Products (Old Bury) Limited, UK to produce Electric resistance welding (ERW) and Cold Drawn Welded (CDW) tubes also called as Drawn Over Mandrel tubes. The International Business Division (IBD) gearing TPI to compete with global tube manufacturers.
Tube Products of India (TPI) is a steel tubes manufacturer based in India. [4] Tube Products of India was established in the year 1955 in collaboration with Tube Products (Old Bury) Limited, UK to produce Electric resistance welding (ERW) and Cold Drawn Welded (CDW) tubes also called as Drawn Over Mandrel tubes.
United Stainless Steel was also created in the UK near London, followed by Marcegaglia U.K., for the production of welded tubes from hot and cold rolled strip, and then by Marcegaglia UK at Dudley, West Midlands. In 1991 Antonio Marcegaglia launched the project which would see the group enter into the transatlantic markets.

There are three classes of manufactured tubing: seamless, [1] as-welded or electric resistant welded (ERW), and drawn-over-mandrel (DOM). Seamless tubing is produced via extrusion or rotary piercing. Drawn-over-mandrel tubing is made from cold-drawn electrical-resistance-welded tube that is drawn through a die and over a mandrel to create such ...
In 1916 Eduard Benteler then bought an engineering factory in Bielefeld in which drawn tubes were manufactured for the first time in 1918. In 1922 Eduard Benteler founded the Benteler-Werke Aktiengesellschaft, which in 1923 started production of seamless and welded tubes in Paderborn and Schloß Neuhaus.
The company was established in 1942 and is based in Chelyabinsk. [3] It is involved in the production and distribution of steel pipes, with its main products being large diameter welded pipes, small diameter hot-worked seamless pipes (108–169 mm diameter) and cold-worked seamless pipes (89–426 mm diameter).

For wire, bar, and tube drawing, the starting stock is drawn through a die to reduce its diameter and increase its length. Drawing is usually performed at room temperature, thus classified as a cold working process; however, drawing may also be performed at higher temperatures to hot work large wires, rods, or hollow tubes in order to reduce ...
