Seamless steel pipe is a kind of pipe made by perforating and rolling round steel billet, with a hollow cross-section and no weld seams around it.

Seamless steel pipe manufacturing process mainly includes hot rolling and cold rolling. Hot-rolled seamless pipe is made by perforating and rolling steel billet at high temperature, with a larger outer diameter and wall thickness, suitable for working conditions with high pressure and high temperature. Cold-rolled seamless pipe is cold-processed on the basis of hot-rolled pipe, making its surface

Seamless steel pipe is a kind of pipe made by perforating and rolling round steel billet, with a hollow cross-section and no weld seams around it.

Seamless steel pipe manufacturing process mainly includes hot rolling and cold rolling. Hot-rolled seamless pipe is made by perforating and rolling steel billet at high temperature, with a larger outer diameter and wall thickness, suitable for working conditions with high pressure and high temperature. Cold-rolled seamless pipe is cold-processed on the basis of hot-rolled pipe, making its surface smoother and dimensional accuracy higher, and is often used in occasions with high precision requirements.

Compared with welded pipes, seamless steel pipes have no welds and are not prone to breakage at the welds, ensuring better sealing when conveying fluids, reducing the possibility of leakage, and being able to withstand higher internal pressures, making them suitable for high-pressure fluid delivery.

In addition, the dimensional accuracy of the outer diameter and wall thickness of seamless pipes is relatively high, which can meet the application of mechanical products with strict dimensional requirements.

The application field of seamless steel pipes is extremely wide. seamless steel pipes can be used to transport resources such as oil and natural gas, and can also be used to manufacture mechanical parts. They are also often used in structural support and pipeline systems.

In the future, the world's demand for seamless steel pipes will show an upward trend

1. The demand for seamless steel pipes will maintain a steady growth trend. With the deepening of energy exploration and mining, the world's demand for energy such as oil and natural gas will increase, so the demand for seamless steel pipes used to transport resources such as oil and natural gas will continue to rise.
2. Infrastructure construction such as urban rail transit and water conservancy projects is still the main construction, so the demand for seamless steel pipes will increase.
