Carbon steel pipes are made of high-quality carbon steel such as 10, 20, 30, 35, 45, 16Mn, 5MnV and other low-alloy structural steels, or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steels are hot-rolled or cold-rolled. 10, 20 and other low carbon steel seamless pipes are mainly used for fluid conveying pipelines. Seamless tubes made of medium carbon steel such as 45 and 40Cr are used to manufacture mechanical parts, such as stressed parts of automobiles and tractors. Generally, carbon steel pipes are used to ensure strength and flattening tests. Hot-rolled steel pipes are delivered in a hot-rolled or heat-treated state; cold-rolled steel pipes are delivered in a heat-treated state.

Square rectangular pipe is a term for square and rectangular pipes, which refers to steel pipes with equal or unequal side lengths. It is rolled from strip steel through process processing. Generally, the strip steel is unpacked, flattened, curled, and welded into circular tubes, which are then rolled into square tubes and cut to the required length.

Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made of low carbon structural steel or low alloy structural steel strip rolled into a pipe billet at a certain angle of the spiral line (called the forming angle) and then the pipe seam is welded together, which can produce large diameter steel pipes from narrower strips of steel.

Welded steel pipe, also known as welded pipe, is made of steel plate  or strip steel after crimping. The production process of welded steel pipe is simple, the production efficiency is higher, the cost is more lower, the product variety is getting richer, but the general strength is lower than seamless steel pipe.

Seamless steel pipe is a kind of long steel with hollow section and no seams around it. It is a kind of economic section steel,seamless steel pipe according to the different cross sectional area shape can be divided into round pipe and special-shaped pipe. Using seamless steel pipe to manufacture ring parts can improve the material utilization rate, simplify the manufacturing process, and save the material and processing time. Widely used in manufacturing structural parts and mechanical parts etc.
