Welded structure - Import export

Alloy 276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high chromium, molybdenum and tungsten contents make the alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition. Alloy 276 is widely used in the most severe environments such as mixed acid chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and recovery of sour oil and gas.

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.
