A seamless steel pipe is a circular pipe without any welded seams. The seamless steel pipe has a hollow section. It is made of carbon steel, alloy steel, stainless steel ingot, or solid tube blank.

There are several processes used to handle the seamless steel pipe: hot rolling, cold rolling, or cold drawing. Seamless steel pipes are considered superior to welded pipes as they are built using monolithic steel billets, with intrinsic mechanical strength, without seam welds.

Characteristics of seamless steel pipe

Seamless steel pipe has a very wide application in engineering and construction fields, it is a hollow steel strip with no seams. It is mainly used as a pipeline to transport liquids.

The steel material used to manufacture seamless steel pipe is one of those heavy types of steel. Compared to the general steel, it has a different look and strong corrosion resistance, resistant to general corrosion. This performance makes seamless steel tubes extend the life.\

CHARACTERISTICS OF SEAMLESS STEEL PIPE ARE AS FOLLOWS:

Smaller diameter.

Weldability strong, high compression capability.

Steel pipe superior performance, relatively dense metal.

Steel Cross area is more complex.

High precision cold-drawn products, good surface quality.

Classification of Seamless Steel Pipe

According to the manufacturing process, the seamless pipe can be divided into hot-rolled seamless steel tubes and cold-drawn seamless steel pipe two kinds. The cold-drawn tube is also divided into the circular pipe and shaped pipe.
