    A333 gr.6 specification for seamless and welded steel tube under low temperature conditions.
    The A333 gr.6 series of seamless steel tubes are similar to AISI's 4032 low alloy steel.
    This standard is applicable to seamless/welded carbon steel and alloy steel tubes with low temperature nominal (average) wall thickness.
    Due to the adverse effect of wall thickness on low temperature impact characteristics, some products may not have dimensions.

    A333 Gr.6

    The ASTM A333 specification covers seamless and welded steel tubes used at low temperatures.In the welding operation, the pipeline is made by seamless or welded process, and no filler metal is added in the welding process.All ASTM A333 seamless and welded pipes shall be processed to control their microstructure.Tensile test, impact test, water pressure test and nondestructive test shall be conducted in accordance with the specified requirements.The A333 alloy pipe is also called seamless and welded steel pipe at low temperature.

    Size DN15-DN700
    Thickness 1mm-100mm
    Length 6m-12m
    Packing Bare packing/bundle packing/crate packing/wooden protection at the both sides of tubes and suitably protected for sea-worthly delivery or as requested.
    Inspection and Testing Chemical Composition Inspection, Mechanical Properties Test(Tensile Strength,Yield Strength, Elongation, Flaring, Flattening, Bending, Hardness, Impact Test), Surface and Dimension Test,No-destructive Test, Hydrostatic Test.
    Surface treatment  Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting. Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested.
