Key Product Features
Heat-exchanging tubes used in high-pressure boilers (with operating pressures generally above 9.8 MPa and operating temperatures between 450°C and 650°C)
must undergo hydrostatic testing, as well as flaring and flattening tests, on a tube-by-tube basis, and are delivered in a heat-treated condition.
Materials include high-quality carbon structural steel (20G, 20MnG) and alloy structural steel (15CrMoG, 12Cr1MoVG).
Application Scenarios and Industries
It is primarily used in the manufacture of components such as steam boiler piping, superheater tubes, headers, economizers, reheaters, and heat exchangers for high-pressure and higher-pressure applications, and is used in fields such as petrochemicals, power generation equipment, and nuclear power facilities.
