Metal Fabrication and Machining for Oil & Gas Industry

Our experience covers almost the complete range of oil and gas components required for Upstream, Midstream and Downstream applications. Due to the continuous improvement required for higher productivity of refineries and petrochemical plants, the thickness, diameter and weight of reactors and vessels have increased drastically and reached the limits of the current manufacturing technology.

We have delivered equipment up to 310 mm thick and a maximum weight of 1000 tons in one single piece.
