Fontijne Grotnes can upgrade competitors’ pipe expanders by installing a straightening system that will improve the straightness of the pipe in all directions, where other systems only control straightness in the plane of the weld-seam.

Fontijne Grotnes successfully improved the horn and drawbar system with the patented connections with cylinder and expander head. When the horn and drawbar of Full Length Pipe Expanders from other suppliers frequently breaks, Fontijne Grotnes can improve the reliability by replacing the drawbar with our patented connection system.
