Pipe expanders and straightening systems

FONTIJNE Grotnes has developed over the years into a specialist in the design and construction of pipe-ends and full length pipe expanders for the pipe industry. The Fontijne Grotnes Expander ensures a constant, reproducible process regarding diameter and mechanical properties. The design maximises the radial forces in order to obtain maximum output in relation to pipe dimensions. A full length pipe expander is an essential part of the production process in a pipe mill. The pipe expander process makes the welding of the pipeline in the field, even cut pipe sections, much easier. Fontijne Grotnes is constantly improving and preparing the full length pipe expander process for new market demands, like higher outputs, greater wall thicknesses, higher material grades up to X120, stricter ovality and straightness tolerances. The Straightening System is a development of Fontijne Grotnes that is especially designed for small pipes ranging

from 16" to 30". The system controls the straightness of the pipes in all directions within ½ API and DNV standards. The company’s pipe end-expander sizes the end of large diameter pipes to parallel-, spherical- and semi-spherical joints. The joints are applicable for, among others, SSAW pipes, mainly used for conveyance of water and sewage. In February 2010 Fontijne Grotnes

opened a new office in Beijing, China. This office represents the company in the Chinese market and will strengthen its position in the pipe, wheel and metal forming industry.
