(SI) services for fossil-fired generating units, including conventional units as well as combined-cycle/HRSG units. Services described in the full-color brochure include high-energy piping management programs, boiler tube failure reduction programs, boiler tubing and header assessments, turbine and generator assessments, CSEF programs, FAC programs, combined-cycle/HRSG consulting and engineering, cycle chemistry programs, and advanced NDE.

» Structural Integrity Overview
A new eight-page, full-color brochure offers an overview of all SI services, including SI's consulting engineering services for the nuclear, fossil, and pipeline industries, and specialized services for SI's Canadian clients. The brochure also includes a description of SI's Expert Solutions services for utility, industrial, legal, and insurance clients.

» Combined-Cycle Chemistry Review
This one-page SI brochure helps to determine if a given combined-cycle/heat recovery steam generator fossil plant would benefit from a one-day SI cycle chemistry program review. Questions include: how many hot, warm, and cold starts is the HRSG designed for; will it reach that number before thermal fatigue failures occur; is feedwater treatment optimized to minimize corrosion product transport and single-phase flow-accelerated corrosion; does it meet the rule of 2 ppb iron in feedwater and 5 ppb iron in evaporators; and is there a proper evaporator water treatment program.

» Conventional Fossil Plant Cycle Chemistry Review
SI's one-page brochure helps to determine if a given conventional fossil power plant would benefit from a one-day SI fossil plant cycle chemistry program review. Questions include: has the plant had repeat chemistry-related damage incidents in the past five years; what are the repeat events responsible for chemistry-related damage; is feedwater treatment optimized to minimize corrosion product transport and single-phase flow-accelerated corrosion; and are there alarms for out-of-specification conditions.

» Flow-Accelerated Corrosion Management
SI's one-page brochure helps to determine if a fleet's flow-accelerated corrosion (FAC) program would benefit from a complete SI FAC program review. Questions include: is there a comprehensive FAC program in place; is the program actively applied throughout the fleet; has all susceptible piping been evaluated to determine locations of greatest risk; how is FAC damage risk determined; how and how often are high-risk areas checked for FAC; and what are the triggers that can increase rates of FAC damage.

» Grade 91 in Heat Recovery Steam Generators
SI's one-page brochure on Grade 91 in heat recovery steam generators (HRSGs) offers a general discussion of the issues recently raised surrounding the integrity of Grade 91 and other creep strength-enhanced ferritic steels, including several failures, forced outages, construction extensions, and premature component replacements — and introduces SI's new asset management program designed specifically for these materials. The program includes review of component and system design; development or review of purchasing/processing specifications, welding programs, and quality control programs; and vendor evaluation and on-site monitoring.

» Grade 91 Material Evaluations
SI's one-page brochure on Grade 91 material evaluations describes Grade 91 issues related to heat treatment and reduced creep properties and SI's material evaluation services. SI offers diagnostic tools to locate and confirm damaged Grade 91 material, including field hardness mapping, linear phased-array ultrasonic examinations, microscopic examination of field replicas, and 500-hour creep indentation testing.

» Heat Recovery Steam Generator Services
SI's one-page brochure on heat recovery steam generator (HRSG) services focuses on root-cause analysis to identify the most probable causes of a HRSG problem, avoiding costly trial and error approaches. SI's problem-solving capabilities cover superheater and reheater tube ruptures, economizer tube fatigue failures, attemperator controls, piping expansion damage, weld cracks in alloys, header end plate failure, and even salvage and restoration of damaged equipment.

» High-Energy Piping Analysis
This one-page brochure describes SI's analysis services for fossil power plant high-energy piping. The analysis results can be used to identify critical piping locations. SI's methodology begins with initial incremental elastic finite element analyses of the support system, cold-spring effects, thermal expansion, and internal pressure: results are used to assess support system adequacy and how predicted stresses compare with Code limits. A final analysis incorporates creep deformation properties of constituent materials, simulating secondary creep behavior over a service interval.

» Materials Science Center
This one-page brochure on SI's state-of-the-art Materials Science Center highlights the wide-ranging capabilities of the Austin, Texas facility, including laboratory and on-site failure investigations, material evaluations, engineering and failure analyses, and nondestructive testing. Some of the Materials Science Center's particular specialties include optical metallography, quantitative microstructural analyses, fractography, scale and deposit analyses, metal chemical analyses, cryo-cracking, and in-place metallography and replications.

» Turbine Generator Overview
This 24-page brochure describes all Structural Integrity Associates, Inc. (SI) Turbine & Generator Assessment services. These include rotor bore machining & surface conditioning; rotor bore inspection; inspection of solid rotors (no bore); generator shaft keyway cracking; steam turbine rotors - blade attachment inspection; inspection of Westinghouse HP turbine inlet sleeves & nozzle chambers; turbine & valve casing crack sizing; steam turbine rotors - disk keyway/bore inspection; economical rotor 'dovetail' inspection alternative for TIL 1292; generator rotor retaining ring inspection; steam turbine/generator rotor forging life assessment; LPRimLife for Windows; generator dovetail analysis; generator retaining ring life assessment using EPRI RRing-Life; turbine & generator engineering consulting; turbine steam chest life assessment; rotor material characterization through miniature samples; material science; and vibration monitoring, testing, & analysis.
