What are the differences of seamless steel pipes and welded pipes?

Steel pipe is a relatively common pipe material. It can be divided into different types such as seamless steel pipes and welded pipes. So what are the differences between seamless steel pipes and welded pipes?

Different craft

Seamless steel pipes are made of steel billets or solid pipes with virtual perforations, and undergo processing operations such as hot transportation or low-temperature transportation. Welded pipes are steel plates or strips that are bent into cones.

Different appearance

There are no welds on the surface of seamless steel pipes, and there are generally welds on the surface of welded pipes.

Different wall thickness

The concentration of seamless steel pipes is low, and the wall thickness is relatively thick. Welded pipes have a high concentration of steel pipes, and the wall thickness is usually thicker than that of welded pipes.

Different raw materials

Seamless steel pipes use billets or solid tube cores. Welded pipes use steel plates or strips.

Different sexual abilities

In terms of corrosion resistance, pressure resistance, and high temperature resistance, seamless steel pipes are better than welded pipes.

Different prices

Seamless steel pipes are more expensive than welded pipes, because the production process of seamless steel pipes is more complex, and its cost is higher.

Different applications

Seamless steel pipes are generally used as pipelines that require special environments such as high pressure resistance and high temperature resistance. Welded pipes are often used as low-pressure fluid delivery pipelines.
