The client had a requirement for large scale gas mains (1.1m diameter) to be manufactured and installed over a 1600m distance.  The pipe work was fabricated in workshops on site by our workforce and our in-house design team were able to provide all the support and structural calculations before submitting their drawings to Corus for approval.  A Corus chemical engineer gave their specifications to us and we designed all the gas flow expansion calculations and the majority of the design calculations for this job.
