Aluminium tubes- welded - Import export

The welding process is one of the core ways in which we manufacture precision tubes. Our high-quality tubing starts off as a flat strip of metal. The strip is formed into a tube through a series of rollers and the join, also called the seam, is then welded together. Welded Processes Special non-destructive testing methods – including eddy current, ultrasonic and pressure testing - are used to ensure a consistent weld. Just like with seamless manufacturing, welded tubes can be drawn down by plug drawing or sinking. This method can be used to create very long lengths of coiled tube, these can also be measured during coiling using a laser measurement. The main welded tube manufacturing processes used are strip welding and cold drawing, but other important processes in between, or at the end of the drawing process, include Please note that we have a minimum order value of £10,000.

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 Please note that we have a minimum order value of £10,000.
