Eddy current and ultrasonic solutions for tubes inspection

(UT/ET) and creates inspection reports that can be used as control evidence for quality service and customers. Data stored can be recalled for analysis and quality treatment. CMS is also well- known for eddy current instruments and systems, and magnetising and demagnetising units. CMS provides remote assistance all over the world for its industrial applications. The company will be at Tube Düsseldorf stand H39, Hall 06. Contrôle Mesure Systèmes – France Email: contactcms@cmseddyscan.com Website: www.cmseddyscan.com

modularity – each block can be changed separately; reliability – totally adapted to customer configuration; it comes in a large range of sizes; real-time WT/ OD/ID; high resolution up to 1µm; high accuracy up to ±2µm; min OD 6mm and WT 0.4mm; and min flaw depth five per cent or ten per cent WT. Due to its great flexibility, RotoUTscan can be adapted to many customers’ configurations. Once installed in a strong control bench it can be combined with eddy current systems to allow a full body inspection of the tube. Supervision software – PROBUS – collects data provided by NDT equipment, displays combined signals

WITH more than 25 years of experience designing and manufacturing eddy current and ultrasonic instruments and systems, Contrôle Mesure Systèmes has installed its ultrasonic rotating head, designed for special steel tube manufacturers like stainless steel, titanium, zirconium and carbon steel worldwide. RotoUTscan, the result of several years of R&D, allows testing of a large diameter range from 6 to 250mm and detects longitudinal and tranversal defects, thickness measurement and OD – ID and ovalisation. The main advantages are: four inspection targets in one system; great

Stainless steel pickling HYDROFLUORIC acid (HF) is very toxic and can potentially cause severe acid burns. It has become an industry norm to use HF, and many are convinced that is the only effective ingredient for cleaning stainless welds and restoring the original properties. the offshore industry where HSEQ is a key focus.

is an alternative for the companies that recognise the need for real action and change, to improve safety.” Kemitura says that in reality many companies based in the EU break the law on a daily basis, when not using a product that is less harmful. The ‘rule of substitution’ describes how all companies should substitute all chemical products where there is an alternative (Council directive 98/24/EC).

Andreas Hensen from Kemitura, commenting on the increased interest in Purefix, said, “It is not a new product at all – we have made it for 20 years, so initially we were a bit surprised. We are not trying to get rid of HF products, that would be naïve. It is in there for a reason, and is very effective. Our pickling paste takes a little longer to have the same effect, but the customers we supply agree with us that this trade-off is still very attractive, when they avoid the very dangerous HF on a daily basis. Purefix

For more than 20 years the Danish chemical company Kemitura has been producing and selling a non-toxic alternative – Purefix © . The company states that changes to EU legislation and increased awareness of worker safety have boosted interest in the unconventional product, for example in
