What types of welded steel pipes are there?

Straight seam steel pipe is a kind of welded steel pipe, which is widely used in daily life. Straight seam steel pipes are very common, but do you know any specific differences between the specifications of straight seam steel pipes?

Welded steel pipes can be divided into many types according to welding methods and uses, straight seam steel pipes and spiral steel pipes are two of them. Because the welding methods between the two steel pipes are different, the performance between the two will also be different, and because the welding methods of the two steel pipes are different, the performance of the two steel pipes will also be different. The steel pipes classified according to the purpose include ordinary welded pipes, wire casings, automobile pipes, oxygen blowing pipes, electric welding thin-walled pipes, etc.

Straight seam steel pipe: With the continuous development of modern welded pipe technology, its quality is getting better and better. Therefore, straight seam steel pipes can replace most steel pipes at this stage, and are widely used in engineering.

Ordinary welded pipe: it is generally used to transport some fluids. Most of this welded pipe is made of low carbon steel pipe, so the welding process uses electric welding, and the thickness meets the steel pipe specification requirements. Nominal pressure pipes are used for pressure, bending, deformation and other tests. In order to pass such tests, although the delivery length of ordinary welded pipes is four to ten meters, they must have certain requirements for the production process and quality of ordinary welded pipes.

Metric welded pipe: The specifications of the metric welded pipe are the same as those of the stainless steel pipe. The metric welded pipe is made of ordinary carbon steel, high-quality carbon steel or alloy steel with low kinetic energy improvement rate, and is welded by electric welding of cold-rolled and hot-rolled strip steel, or using heat The cold-drawn electric welding technology welding after the rolled strip is welded.

Metric welded pipes are divided into two types: ordinary pipes and thin-walled pipes. Prefabricated parts for automotive drive shafts or transport fluid forces are their main areas of application. Thin-walled tubes are used in the manufacture of furniture, lighting equipment, etc., to help enterprises produce.

Idle pipe: Idle pipe is a very special steel pipe, which will be tested for pressure and deformation during the production process, and is mainly used as an electric welded steel pipe for belt rotation.

Spiral steel pipe: The high carbon steel strip can be cold rolled into a tube billet according to the helix angle (called forming angle) set by the general structural steel or low alloy structure, and then the pipe seams are welded together to form a straight pipe. Welded steel pipes and spiral steel pipes are used for petrochemical transportation. Spiral steel pipes have single-sided and double-sided welding as well as front and back welding, and the welded specifications are controlled by the type of steel pipe.

Welded steel pipes are divided into many types, and the production methods are different for different purposes. I hope you can learn a little bit through the above introduction. If you have any questions about steel pipes, please feel free to contact us
