Combined Cycle Unit Superheater and Reheater Tube Module Replacement

BEIS were engaged as the client representative for the pressure parts engineering and quality assurance surveillance of a large heat recovery steam generator superheater and reheater tube module retrofit, fabricated from Grade 91 material.

The retrofit installation required complex removal and reinstallation of major boiler components including high temperature steam headers and tie-ins to high energy piping. BEIS were able to provide site-based technical engineering expertise to deliver:

As a result, all tie-ins were accurate and positioned such that the welding and critical heat treatments could be implemented in a way that provided the best possible outcome for design compliance, quality and future plant fitness-for-service., giving the Client a high degree of confidence in their high energy piping integrity and plant reliability.
