welding of steel & pipelines

Our company is experienced in working according to EN and ASME standards. The welding methods we have used so far are: 111 (coated electrode) and 141 (TIG). We have gained experience with the renovation of drilling platforms (including the H6e project at Stord for Aker Solutions) and with the construction of a power plant based on a set of gas and steam turbines, where we were a subcontractor for the assembly of all pipelines (the Mongstad refinery in Norway for Dong Energy).

Our technologies are recognized in accordance with the EN 15614 standard and the DNV standard, for the following scope:

Material group 8 – wall thickness of the material to be welded 3-22 mm, pipe diameters over 30 mm. Welding with the 141 method

Material group 1 – wall thickness of the material to be welded 3-19 mm, pipe diameters over 25 mm. Welding with the 141 method

Material group 1 – wall thickness of the welded material 8-32 mm, pipe diameters over 138 mm. Welding using the 141 + 111 method
