Alloy pipes are a type of seamless steel pipe with superior performance compared to ordinary seamless steel pipes, primarily due to higher Chromium content. They offer unmatched resistance to high and low temperatures, as well as corrosion, which makes them extensively used in the oil, chemical, power, and boiler industries.
Alloy tubes are primarily used as heating surface tubes for low and medium-pressure boilers (operating pressure generally not exceeding 5.88 MPa, and operating temperature below 450°C); they are also used for heating surface tubes, economizers, superheaters, reheaters, and petrochemical industry pipes in high-pressure boilers (operating pressure usually above 9.8 MPa, and operating temperature between 450°C and 650°C). High-pressure alloy tube grades include: 15CrMoG, 12Cr2MoG, 12Cr1MoVG, 12Cr2MoWVTiB, 10Cr9Mo1VNb, SA210A1, SA210C, SA213 T11, SA213 T12, SA213 T22, SA213 T23, SA213 T91, SA213 T92, ST45.8/Ⅲ, 15Mo3, 13CrMo44, 10CrMo910, etc.
