Project Description

European and Japanese Standard Boiler Tubes

Product Description

Boiler tubes are primarily used in supercritical or ultra-supercritical boilers for components such as superheaters, reheaters, water walls, and economizers. These tubes require high long-term strength, excellent anti-oxidation and corrosion resistance, as well as good structural stability.

Product Features

Boiler tubes often operate under high temperature and pressure conditions. The tubes can experience oxidation and corrosion under the influence of high-temperature flue gas and steam. Therefore, boiler steel tubes must have high long-term strength, excellent anti-oxidation and corrosion resistance, and good structural stability.
