Tubular stainless steel

The Alleima program covers tubes for many types of boiler applications. We offer, for example, superheater tubes and reheater tubes in a comprehensive range of stainless steels and nickel alloys. We also produce composite tubes, consisting of two different alloys fully bonded together. Our products are used in most types of boilers, such as: Advanced ultra supercritical (AUSC) boilers Biomass-fired boilers Black liquor recovery boilers Coal-fired power boilers Concentrated solar power (CSP) boilers Reheaters Superheaters Syngas coolers Waste heat boilers Increased efficiency in coal-fired power boilers Our new material Sanicro® 25 is engineered for the next generation of coal-fired power boilers, contributing to significantly greater efficiency and sharply lower CO2 emissions. Sanicro® 25 is ideal for superheater and reheater tubes, allowing for material temperatures of up to 700ºC (1290ºF).
