  • Nylon Coating Bundy Tube

    Bundy tube, also called Bundy pipe, is a double wall copper brazed steel tube. The manufacture of Bundy tube is a continuous process of rolling a copper coated steel strip through 720 degrees, brazing the outer and inner circle of the strip together by the melted copper layer to form a round tube with a continuous circular seam, and annealing. We are using fully automatic production lines with online process monitoring and continuous fabrication of the Bundy tubes.
    The bundy steel tube has fine inside cleanness, high strength, nice elongation, good foundation for late process , anti leakage, anti high pressure explosion, excellent anti corrosion power after surface treatment. It is an ideal material for tubes of  automotive industry.The tube can be provided in coils or cut to length,etc.Thickness of Nylon coating: ≥150μm.
