pipe used in bridge construction project

ASTM A513 ERW carbon steel pipe is a straight seam electric resistance welded (ERW) carbon steel pipe produced in accordance with ASTM A513 standards.

The processing of brazed spiral finned tube is carried out in two steps. First, the steel strip plane perpendicular to the axis of the tube is wound on the outer surface of the tube in a spiral line manner, and the ends of the steel strip are welded to the steel pipe and fixed, and then the steel strip and steel pipe are welded together by brazing in order to eliminate the gap between the steel strip and the steel pipe contact.

42crmo4 seamless steel pipe is a high strength, high toughness, corrosion resistant alloy structural steel, widely used in mining machinery manufacturing field.
