Ductile iron pipes refer to pipes made by high-speed centrifugal casting of cast iron with a diameter of 18 or above, after adding spheroidizing agents, using a centrifugal ductile iron machine. They are commonly referred to as ductile pipes, ductile iron pipes, and ductile iron pipes. Mainly used for the transportation of tap water, it is an ideal material for tap water pipelines.

Straight seam welded pipe is a type of pipe made by welding hot-rolled or cold-rolled steel plates or strips onto welding equipment, and is called a straight seam welded pipe. (Named after the straight line formed by the welding of steel pipes).

Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip into a pipe blank at a certain angle of the spiral line (called the forming angle), and then welding the pipe seam together. It can produce large-diameter steel pipes with narrower strip steel. The specifications are expressed as outer diameter * wall thickness, and the welded pipe should ensure that the hydrostatic test, tensile strength, and cold bending performance of the weld meet the requirements.
