  • Alloy Steel Tube

    Alloy Steel Tube

    It is to manufacture wall panel, economizer, reheater, superheater and steam pipeline of boilers.
    Low temperature resistant alloy tubes are seamless products,mianly the finished steel pipe has good impact toughness in low temperature environment (usually below -45℃).
    The use of low sulfur and low phosphorus high purity steel and calcification treatment can effectively reduce the low temperature brittleness of steel and enhance the impact toughness of the product.

    Application: In Refineries, Power Plants, Boilers, Heat Exchangers, Condensers etc.
    Pipe Standard: ASME SA 335/ASTM A333/ASME SA333  
    Size: OD: 73-630mm / WT: 6-35mm / Length: Single Random, Double Random, Cut Length
