Fabrication of Unit Piping for Moomba Compression Station ($3m)
Welding of carbon and stainless pipe spools (from 25NB SCH 10 to 600NB SCH 160)
Total project value $4-5 million
3364 welds completed on this project with only 26 welds failing to comply with the nominated standard AS4037 Class 1. Going by the TWI a 1.7% to 3% failure rate is the average for piping systems based on a lot of factors such as material grade, type of defect detected and welding process used.
