- Welded and Redrawn Tubes

Welded and redrawn tube manufacturing employs elements of both the welded and seamless processes.

A welded and redrawn tube is welded in a conventional manner but then transferred to our seamless mill, located in the same factory. Here the product is redrawn to achieve a welded and redrawn finish.

The objective of redrawing is to achieve homogenisation of the weld following annealing by cold working. This refines the structure of the weld resulting in improvements that include:

- Better corrosion resistance

- Improved fatigue life

- Higher mechanical integrity
