Product Description

Steel Spiral Duct pipe, also known as spiral steel pipe or spiral welded pipe, is brought low carbon structural steel and low alloy steel strip according to certain helix Angle (called forming Angle) rolled into a tube billet, and then welded pipe joints made of, it can use a narrow strip in the production of large diameter steel pipe.The spiral pipe is mainly used for oil and gas pipeline, and its specification is indicated by the outer diameter * wall thickness. The spiral tube can be divided into single side welding and double sides welding, and the welding pipe shall ensure that the water pressure test, the tensile strength of the weld and the cold bending performance are in accordance with the regulations.
