Sterling subcontracts pressure vessel fabrication as do most deaerator suppliers. Fabrication facilities are prequalified by Sterling and must meet ASME codes and standards as well as Sterling's own stringent requirements. Sterling utilizes fabrication facilities around the Globe and continues to explore new facilities in order to compete in today's global market. In addition, Sterling has its own fabrication facility where deaerator internal components and boiler feed systems can be manufactured. This helps assure that the components which are critical to performance are manufactured to the highest standards.
