Your superheaters and reheaters are far from ordinary heat exchangers. Operating at steam temperatures ranging from 600°C to 1,120°C, they demand special materials. To address these challenges, we offer advanced alloy stainless steel superheater tubing, designed to withstand extreme heat, resist corrosion and keep your operations running smoothly with zero shutdowns.
For many of our customers, superheaters and reheaters serve as rugged on-site workhorses, playing a vital role in boosting the operational efficiency of their plants. Day in and day out, they support thermal power plants and other steam-driven systems, where they elevate steam temperatures beyond the saturation point, ensuring the steam remains dry and superheated. This improves energy transfer capability, contributing to reduced CO2 emissions and more sustainable operation.
Alleima superheaters tube covers a wide range of fuel types, such as coal, gas, oil, black liquor and biomass. Our range consists of stainless steels and nickel alloys in the outer diameters 12 to 260 mm (0.472 to 10.24 in.).
Key requirements for superheater tube
- High resistance to corrosion and scaling
- Ability to withstand high temperatures and pressures
- Essential to use stainless steel or alloy steel
Industries using superheater tube
- Power generation: Coal-fired power plants, gas-fired power plants, nuclear power plants
- Petrochemical and oil & gas: Refineries for processing heating and steam crackers, steam reformers and chemical processing
- Chemical industry: Production of chemicals and fertilizers, ammonia production, chemical synthesis
- Pulp and paper: Recovery boilers and power boilers for processing steam and electricity generation
- Marine and shipping: Used in marine boilers to power turbines for propulsion in ships
- Steel and metal production: Used in blast furnaces, annealing processes, and steam-powered turbines
Increased efficiency in coal-fired power boilers
One of our latest innovations, Sanicro® 25 (S31035), is a high-alloy austenitic stainless steel specially designed for the next generation of coal-fired power boilers. With its very high creep strength and resistance to oxidation, this advanced material helps achieve significantly higher efficiency and sharply lower CO2 emissions. Perfect for superheater and reheater tubes, it can handle material temperatures of up to 700°C (1290°F). Read more about Sanicro® 25.
