ORBITAL WELDING
Picture of Orbital Fusion process for boiler tube to eliminate couplings.Picture of Orbital welding return bends at the APS West Phoenix Power Plant.Steam Generation Corporation has completely retubed seven General Electric combined cycle HRSG boilers which consist of a superheat section, evaporator section, and economizer section. SGC has retubed four for SRP at the Santan Generating Station in Gilbert, Arizona and three at the APS West Phoenix Power Plant.

Our innovative process of orbital welding has eliminated the existing coupling design that was prone to failure. Steam Generation Corporation has made in excess of 12,000 orbital welds with no failures upon hydro.
