Coal Fired Power Plants

Coal Fired

Technologies for critical environments

Coal-fired power plants produce electricity by burning coal in a steam generator that transforms water into high pressure and high temperature steam. The steam flows through a series of steam turbines which drive an electrical generator to produce electricity. The exhaust steam from the turbines is cooled, condensed back into water and finally returned to the steam generator to start the process once again.

alloy and Stainless steels for high pressures and high temperatures

For this application, we supply tubes and pipes in carbon steel, alloy steel (T/P11, 13CrMo4-5, T/P22, 10CrMo9-10, P36, 15NiCuMoNb564, T/P23, 7CrWVMoNb9-6), high alloy steel (T/P91, X10CrMoVNb9-1, T/P92, X10CrWMoVNb9-2, X20CrMoV11-1) and stainless steels (TEMPALOY AA-1 and A-3) used for boilers, water walls,feed-water tubes and pipes,super heaters and re-heaters as well as for headers, steam lines, connection pipes and other power plant apparatus required to withstand high temperatures and high pressures.

Ultra Super Critical Applications

Tenaris is currently producing 9% Cr tubular products (ASTM grades 91 and 92 and EN equivalents) used for the fabrication of boiler pressure parts working at temperatures up to 620°C. Additionally, for the fabrication of super-heaters and re-heaters, in the most advanced Ultra Super Critical (USC) power plants working with steam temperatures up to 650°C, we offer ASTM A213 S30434 and S30942 grades (TEMPALOY AA-1 and A-3). All these steel grades have elevated creep resistance combined with good resistance to oxidation.

Quality Certifications

All Tenaris products for coal-fired power plants are designed according to the most stringent quality standards and manufactured under the certified quality system (ISO 9001). Quality control procedures include statistical process controls, process and product audits as well as traceability systems covering all manufacturers involved.
