Hastelloy C-276 welded pipe

Hastelloy C-276 is a nickel-based alloy containing elements such as molybdenum, chromium and tungsten, giving it excellent corrosion resistance in a variety of corrosive environments, especially suitable for use in environments containing chloride. S32760 (Also known as Super Dual-phase Steel 2507) is a dual-phase stainless steel that combines the advantages of austenite and ferric body stainless steel, with higher strength and better spot corrosion resistance and gap corrosion resistance.

    Hastelloy C-276 Features of welded pipe


    Corrosion resistance: Hastelloy C-276 welded pipes exhibit excellent corrosion resistance in a variety of corrosive media, including both oxidation and reducing environments.
    Welding performance: Hastelloy C-276 welded pipe is easy to weld, and it can still maintain good corrosion resistance after welding.
    High temperature performance: At high temperature, Hastelloy C-276 welded pipe can still maintain good mechanical properties and corrosion resistance.
    Production Engineering:

    Raw material preparation


    Use Hastelloy C-276 or S32760 sheet or strip conforming to ASTM A249 or ASTM A312 standards as raw material.

    Shear and edge preparation


    Sile plates or strips to appropriate sizes and process edges to ensure accurate docking during welding.

    Roll


    the cut plate or strip roll into a tube.

    Welding


    Weld the edges of the pipe using welding techniques such as TIG (tungsten pole argon arc welding) or MIG (metal inert gas protection welding).

    Heat treatment


    After the welding is completed, the welded pipe is fixed by heat treatment to restore the corrosion resistance and mechanical properties of the material.

    Straighten and cut


    Straighten and cut the welded pipe to achieve the desired size and shape.

    NDT


    Conduct nondestructive testing such as ultrasonic testing or radiographic testing to ensure that the welded pipe is free of defects.

    Surface treatment


    Surface-treat the welded pipes, such as pickling, passivation or polishing, to improve their corrosion resistance and aesthetics.

    Inspection and testing


    Final inspection and testing of welded pipes, including dimensional inspection, pressure test and chemical composition analysis.

    Packaging and transportation


    Qualified welded pipes are properly packed and ready for shipment.
