A History of Innovation and Success > Since 1910, Elliott Company has earned a reputation for providing innovative solutions, unmatched expertise, and first-class service to the global turbomachinery marketplace. Elliott has designed, tested, and installed some of the industrys most rugged and dependable equip- ment. In fact, some Elliott compressors and tur- bines installed in the 1940s and 1950s are still in operation today, either as originally supplied or upgraded to handle new process conditions or more stringent environmental standards. We have been on the cutting edge of...

ADVANCED TECHNOLOGY Through our EDGE development program, we combine our comprehensive knowledge of turboma- chinery with the latest design software, manufacturing processes, and machine tools. As a result, Elliotts multi-stage centrifugal compressors lead the industry in both performance and reliability. Through extensive research in the fields of rotor-dy-namic stability, aerodynamic cross-coupling stiffness, and rotor-bearing systems, we have developed proprietary analytical tools. Incorporating these developments into Elliott compressor designs has produced a number of product...

CASING FEATURES Elliott designed our EDGE compressor casings to re-duce the required manufacturing steps and simplify field assembly. To achieve higher operating pressures, we applied state-of-the-art solids modeling and finite element analysis techniques. Small and mid-sized horizontally split casing sec-tions are made from a single piece of rolled steel plate with horizontal flanges that are machinednot weldedחinto the side. Cast steel casings are used for some applications. High-strength casing through- bolts provide superior clamping forces. Endwalls are made from a single solid plate....

OTHER FEATURES As part of our comprehensive EDGE develop-ment program, ElliottҒs engineers examined each compressor component to find ways to support our goals of higher efficiency, lower cost, simpler maintenance, and reduced cycle time. Our designs reflect our commitment to making our products the best in the industry, down to the last detail.Interstage and balance piston sealing is accomplished through two component features. First, we use abradable or deflection-tolerant materials such as fluorosint or nickel-graphite on stationary sealing surfaces. Second, we machine teeth onto the...

Our engineering and manufacturing facilities in Jeannette, Pennsylva- nia, and Sodegaura, Japan, rank among the worlds most advanced for turbomachinery design, production, and testing. Our combined manufacturing capabilities include Masterhead machining centers for casing ma- chining, rotor machining centers,...

COMPRESSOR FRAME SUMMARIES 2,000137.901,500103.42 2,000137.902,000103.42 In developing the EDGE compressor product line, we focused on standardizing components and hard- ware to reduce costs and improve reliability across a wide array of applications. The EDGE product line consists of 15 standard frame sizes, which are scaled from the 38M median frame size. Casing bores and internal aerodynamic hardware, such as impellers, diaphragms, and shafts, are scaled. Scaling aerody-namic components improves performance predictabil- ity and increases reliability by preserving geometric similarity...
