The production of large-diameter pipes leads to a huge strain on the thread of the expanders’ tension rods. With HELICOIL® thread inserts, the service life of the tool could be elongated.

During the production of large-diameter pipes, dual-head expanders are used for the last forming process.
By means of this expander, the welded pipes are gradually enlarged in order to achieve the accuracy grade and the required geometrical data. Based on the pipe features such as diameter, wall thickness and steel grade, the expansion rate may vary between 0.8 % and 1.5 %. The permanent strain of up to 1,500 tons tensile load caused the thread wear at the expander's drawbar. The resulting costs called for a lasting improvement.

Heavy loads call for excellent answers. Together with EUROPIPE, an ideal solution has been developed. Here, a HELICOIL® thread insert is screwed into the tension rod nut for effecting an improved dispersal of the preload force during the mechanical expansion. An increased fatigue strength of the thread guarantees a significantly longer service life of the mechanical expander.
For EUROPIPE, we have produced our largest HELICOIL® thread inserts of all time, measuring
204 x 16 x 282 mm, 260 x 20 x 330 mm and 320 x 25 x 420 mm.
We work closely with our customers to develop tailor-made solutions. In this case as well.
HELICOIL® inserts create wear-resistant and high-precision threads. With HELICOIL® thread inserts, the service life of the tool could be elongated.
