Products Details

Seamless steel pipe is a kind of long steel with a hollow section and no joints around. It is made by hot rolling, cold rolling or cold drawing and other processes, and is widely used in petroleum, chemical industry, boilers, ships, automobiles, machinery manufacturing and other fields.

The main features of seamless steel pipe include:

High strength: Because there is no joint in the manufacturing process of seamless steel pipe, it has a high overall strength and good pressure performance.
Good pressure resistance: seamless steel pipe has good sealing performance and can withstand high internal pressure.
Wear resistance: Seamless steel pipe has smooth surface and good wear resistance.
Corrosion resistance: According to different manufacturing processes and materials, seamless steel pipes have certain corrosion resistance.
Easy to process: seamless steel pipes can be cut, welded, bent and other processing according to needs.
The classification of seamless steel pipes is diverse, and can be classified according to its use, material, size, etc. Common materials are carbon steel, alloy steel, stainless steel and so on. According to the use, seamless steel pipes can be divided into seamless steel pipes for structure, seamless steel pipes for fluid transportation, seamless steel pipes for boilers, seamless steel pipes for ships, etc. According to the size, it can be divided into small diameter, medium diameter and large diameter seamless steel pipes.

The production process of seamless steel pipe includes material selection, heating, perforation, rolling, sizing, cooling, straightening, inspection and other steps. High-quality seamless steel pipes require strict production control and quality testing to ensure that their performance meets the requirements of different applications.
