A modern power generation station requires many different types of heat exchange and process equipment. The most critical of all, especially for the nuclear industry, is the steam generator. In nuclear power generation, the steam circuit must be separate from water circuit. It's the most critical sub-assembly of one of the most critical aspects of a nuclear reactor.
TARUS multi-spindle BTA machines are used to drill the many thousands of deepholes in critical tube sheets components with great precision. Tube sheets for heat exchangers are prevalent many applications such as coal and gas fired power generation, oil & gas process equipment, petrochemicals, pharmaceutical production, breweries, and more.
Impellers have wide ranging application from pumps, to turbines, to turbochargers. Machining impellers benefits from simultaneous 5-axis milling, and requires extremely tight-tolerance geometry. The TARUS UNIMAX series is perfect for this application.
Tube sheets are critical supporting elements in heat exchangers. They consist of a dense arrangement of thin walled tubes situated inside an enclosed, tubular shell. Tubes are supported on either end by sheets which are drilled in a predetermined pattern to allow the tube ends to pass through the sheet. The ends of the tubes which penetrate the tube sheet are expanded to lock them in place and form a seal.
