PIPING SPOOLS PREFABRICATION

Prefabrication of piping is a common strategy to shorten construction schedules and reduce field labor, particularly for combined cycle plants. High-pressure, high-temperature critical process systems must be welded, but there are economic, schedule and constructability advantages to using grooved mechanical piping for balance-of-plant (BOP) water, air and utility systems. Prefabricating pipe spools with grooved-end components increases fabrication shop productivity and eases field installation, resulting in a much shorter fabrication and installation schedule.
