Bore Enlargement of a Reactor in a Chemical Plant

5 tons of steel converted into metal cuttings

In August 1998, the internal diameter of an 8 m high reactor vessel was enlarged with a transportable boring device and high-performance cutting tools. Our mechanics worked in shifts – 24 hours a day.

The goal was: to achieve a final diameter of 730 mm (0/+0.35) in the reactor area, and a final diameter of 760 mm (0/+0.35) in the motor area; 35 mm of the radius needed to be bored.

Cutting tool and bore alignment equipment

This was the first time that such work was carried out on-site.

With these measures, the volume of the reactor vessel was increased by 20%. In 2000, the same work was successfully implemented in a chemical plant in the Middle East.

Final surface quality: Ra 0.4
