Siemens SGT5-2000E 2nd stage vane

HGTP provides design and manufacturing of new Steam turbine components in both hot and cold sections. We focus on lifetime extension and performance improvement of your equipment. We have unique insight into designing a high quality product that is compatible and interchangeable with the original equipment. All vane kits include installation hardware suitable for installation in Siemens V94.2 / SGT5-2000E gas turbines.

The second stage vane is also manufactured through an investment casting process using the nickel-based super alloy Inconel 738LC. The second stage vane features trailing edge cooling and internal impingement cooling. Depending on the component version (3, 4, 5, or 6), different coatings and coating systems are applied. The second stage vane is coated with a MCrAlY coating to protect the base material against oxidation and corrosion. In addition, TBC is applied to prevent the base material from overheating and to reduce thermal gradients along the hot gas path.
