This project was on a very tight timeline as the elements needed to be replaced at the next outage of the boiler. The entire manufacture of the 80 elements weighing a total of approx. 100 tonnes was completed in 3 months. There were in excess of 4000 bends meeting strict ovality (5%max) and thinning (8%max) criteria. Tube size was dia 44.5 x 6.3mm. Welding comprised of 1680 butt weld joints and 3040 attachment welds. Notable mention was U-Neek organised all material including directly importing alloy steel tube and plate from overseas mills.
