Inspection, testing & quality control Inspection, testing and quality control leave no imprint on the product but without them it could be that the tube or pipe has a fault or minor error that could mean it is not fit for purpose or could present a danger to the public. Without this technology tube and pipe manufacturers would be unable to offer – and stand behind – the superb, high-tech, saleable commodities for which they are justly renowned.

Tube China 2010

Extrusion, drawing and reducing

Tube China 2010 will be held from 21 to 24 September 2010 in the Shanghai New International Expo Center and is designed to assist the effort to explore the opportunities offered by the booming Chinese economy – which is now the second-largest worldwide and showing no signs of let-up. This year’s event is expected to cover 69,000 square metres and embrace more than 1,200 exhibitors, making it the largest in history in terms of scale.

As with most mature and perfected technologies, the reductive processes of tube and pipe manufacture are dependable. Whether the project calls for pushing, as in extrusion, or pulling, as in drawing, the customer of a modern mill, no less than its operator, confidently expects a sound, flawless product, which is remarkable given the variety of requirements tubing or pipe from a typical production run must satisfy.
