Swedged Pipe for Top Driven Piles

Swedged Pipe for Top Driven Piles

Swedging is the process of changing the diameter of metal tubing. Usually it is done to join two pieces of steel pipe by expanding the diameter of one piece so another will slip inside as a join.

We can provide bespoke swedged joining systems for the top driven piling market in diameters from 140 mm to 244 mm and supplied in lengths to specific requirements.

Contact us to find out more.
