In the case of greater wall thickness, tubes are usually produced seamlessly. For this purpose, the tube is produced from a single block using the extrusion process, and then brought to the finished dimension. The resulting tubes are completely homogeneous and allow higher operating pressures than welded tubes.

Tubes in welded version

In addition to the seamless pipes, we also carry a large range of welded products. Usually, welded tubes are produced that have a small wall thickness relative to the wall thickness. First, a hollow body is produced – by rolling or bending sheet metal -, which is then welded at the joints.

We do not just supply pipes, but the complete piping range from our stock

Of course, WITTE TUBE + PIPE SYSTEMS GMBH stores all the fittings appropriate for the pipe. Here again, equipping our warehouse with supplies beyond standard requirements is one of the principles we have made our own.

We stock fittings from low-cost Chinese production, which are 100% TÜV-approved and additionally inspected by our own quality assurance department. In addition, we stock all kinds of fittings produced in western Europe, which we also inspect according to the applicable regulations, as well as for material mix-up.
