We construct, manufacture, deliver and assemble pipes with fittings, pumps and other aggregates.

We manufacture steel constructions acc. DIN 18800-7, pressure vessels and tanks acc. to AD-HP0, systems of water hazardous mediums acc. to WHG 19 l and gas- and water pipes and systems acc. to AD-HP0 or according to special guidelines.

Due to that work we use TÜV / MOT-approved welders for several welding processes, like WIG/TIG-welding, MIG-welding, MAG-welding and MMA-welding.

We certainly also offer the testing of the welding. For example X-ray examination or ultrasound examination are not a problem at all.

For some applications it might be necessary to add external inspectors to observe the welding processes. In such cases we cooperate with SLV (Schweißtechnische Lehr- und Versuchsanstalt Mannheim).
