Welding and finishing lines for API tube production

and a testing line for tubes up to 7". One of the highlights of this line is the fully automated high-precision ten-roll- straightener. As a result of several new developments the changeover time of the entire line is claimed to be the shortest in this industry. With these installations as a reference the Asmag Group has shown its expertise in supplying machinery and fully integrated production lines according to the API standard, from the sheet coil to the ready-for-sale tube bundles. The Asmag Group manufactures its machines and installations in its own workshops in Austria and Germany. At each location the engineering, automation, manufacturing and assembly are under a single roof, resulting in high manufacturing quality, flexibility and improved service and support.

fully developed cage forming technology (CTA) and special multi-head saw design convinced the company to choose a Seuthe mill. The delivered cage forming mill is able to produce a wide diameter range from 60.3 to 219.1mm by automatic roll adjustment of only one universal forming roll set. For a steel tube manufacturer in Germany, the Asmag group has supplied two high-precision steel tube welding lines and a finishing line for API tube, also in 2013. The API tube finishing line includes a straightening machine, a cutting and chamfering unit

THE Asmag Group is a supplier of machinery and equipment for the steel and non-ferrous metal industry. It combines two enterprises: Asmag, whose core business is the design and manufacture of drawing, straightening, testing, cutting, chamfering, stacking and bundling machines; and Seuthe, with its core business of design and manufacture of tube welding and section mills. In 2013 a Saudi Arabian producer of steel pipes for the oil and gas industry installed a mill to strengthen one of its business segments for 8" API pipes. The

overlaid or co-extruded product for super- heater tubing and it is playing a major role in the worldwide growth of municipal waste-to-energy and bio fuel production. Corrotherm International has an extensive range of material supply that includes over 110 nickel alloy grades, together with the complete range of Duplex and Super Duplex, copper nickel and titanium. The company is able to supply a wide range of product forms, which enables it to supply complete packages of pipe, fittings, flanges, plates, bars and welding consumables.

The original goal for the application of Inconel Alloy 625 was for main steam- line piping. Since then, it has been used extensively in a variety of industries, including aerospace, chemical processing, marine and pulp and paper. As an indication of its versatility, slight modifications in composition and mill practice have dramatically increased the fatigue life of thin sheet, thereby increasing the design capabilities in critical turbine components. The excellent weldability of the alloy, and its ability to be joined very successfully to other alloys with different compositions, has also led to the use of Inconel Alloy 625 filler metals for welding dissimilar materials. The latest developments have led to Inconel Alloy 625 being used as weld

RARELY does an alloy become a standard material of construction in a wide variety of industrial applications. Inconel Alloy 625 is, however, such an alloy. Jan Ward, CEO of nickel alloy specialist Corrotherm, explains its form and uses. Ever since its introduction to the market in the early 1960s, Inconel Alloy 625 has proven to be a valuable and versatile material that is able to solve a wide variety of design and application problems. The alloy has the ability to resist low temperature aggressive corrosion environments, as well as hostile high temperature environments, and performs with a high level of strength that has enabled it to be specified frequently in a cross section of industries.
