the field as the pipes are sized over their full length. Straightness and ovality are influenced by the use of higher material grades and the forming and welding processes prior to expanding. Stresses inside the material are therefore released during the expanding process and cause bending of the pipes in all directions. The new straightening machine avoids these problems and instead ensures constant mill production for size and mechanical properties. The new straightening system guarantees straight pipes within 1 / 2 -API and DNV- standards. It is designed in such a way that it can also be mounted on existing expanders. The grease system in the expander heads was also improved to withstand the consequences of using higher material grades. This process is completed by the company’s equipment for pre- and post-washing installations. Fontijne Grotnes BV has been supplying expanding equipment since the 1960s, when it introduced a mechanical expander for LSAW-pipes.

Forster manufactures welded and cold- drawn precision steel tubes following user- specific requirements, according to EN 10305-2, EN 10305-3 and EN 10305-5. In circumstances where expensive seamless or cold drawn tubes (EN 10305- 1 or EN 10305-2) are used, Forster can in many cases offer more cost-efficient welded alternatives (EN 10305-3). The Forster precision steel tubes range is OD 12-76mm with wall thickness from 0.8- 6mm, and for cold drawn products from OD 8-76mm with wall thickness from 0.8- 6mm.

At Tube 2008, Fontijne Grotnes will promote its newly developed straightening system for mechanical expanders. This machine controls the straightness of pipes in all directions, where other systems only control straightness in the plane of the weld-seam. Tolerances for ovality and straightness of pipes are becoming increasingly important to the later laying of pipes in the field. This also applies when pipe sections are cut in fi A pipe expander including new straightener, expander heads, draw bar for larger diameters and several tools
