GE Acquires Metem Corporation to Improve Supply Chain Efficiency
SCHENECTADY, NY: GE announces the acquisition of Metem Corporation, a supplier of turbine super-alloy component machining for the power generation companies and aerospace industries. The acquisition brings out cooling hole-drilling capability in-house to enable efficient functioning of heavy-duty gas turbine engines when subjected to high temperature operations.
The new cooling hole-drilling technology involves laser drilled holes at shallow angles on the surface of the turbine engines at a rate of 0.3 to 3 holes per second. Their ability to drill holes at 15 to 90 degrees at the surface has enabled new designs by incorporating film cooling holes into the turbine blade designs. Film cooling is done by passing cool air from the compressor stage into the internal chambers of the turbine blades and discharged through small holes in the blade walls. This discharged air acts as a thin, cool, and insulating blanket along the external surface of the blade. This film cooling holes in turbine engines improve fuel efficiency; reduce noise, combats & averts failure of turbine blades and lowers mono nitrogen oxides (NOx) and carbon monoxide emissions.
The cooling hole drilling capability helps to improvise supply chain efficiency and reduce cost of the products. It also expands GE’s in-house capability by providing a fully integrated, engineered and comprehensive machining solution to its customers.
“Gas turbines coupled with services are the core of GE Power. Our acquisition of Alstom’s power business has significantly improved our competitiveness, particularly in our technology leadership position and global presence. But we have not stopped there,” says Mike Chanatry, VP of Gas Power Systems Supply Chain.
