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 characteristics as dependable weld integrity, dimensional accuracy, and an excellent surface finish.

Tube Investments of India is a flagship company of Murugappa Group.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.
deep drawn tubes for bellows Metal bellows. There are three main types of metal bellows: formed, welded and electroformed. Formed bellows are produced by reworking tubes, normally produced by deep drawing, with a variety of processes, including cold forming (rolling), and hydroforming. They are also called convoluted bellows or sylphons.
Cold welding or contact welding is a solid-state welding process in which joining takes place without fusion or heating at the interface of the two parts to be welded. Unlike in fusion welding , no liquid or molten phase is present in the joint.
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 ...
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.
