Durability Improvements

Power Services Group has developed and proven advanced processes to increase durability and prolong component life. One process, a weld application of a stellite alloy to valve wear areas, results in superior wear and corrosion resistance. The stellite overlay has proven to virtually eliminate scale buildup and erosion of parts in the steam path. In addition, Power Services Group has complete in-house gas nitriding capability.

Gas nitriding is a surface hardening process, where nitrogen is added to the surface of steel parts using dissociated ammonia as the source. Gas nitriding develops a very hard case in a component at relatively low temperature, without the need for quenching. As a result, a very high strength product with extremely good wear resistance can be produced, with little or no dimensional change. For valve components, these material enhancements translate into increased durability and service life and ultimately, reduced maintenance cost.

All parts supplied by Power Services Group meet or exceed the PSG original standards and specs with a full warranty against defects from time of purchase. Every part, component or accessory we provide – whether it’s for a steam turbine valve or mechanical drive system – is backed by our reputation for getting it right the first time, on time, and at prices you can afford.
