What are the common categories of seamless steel pipes?

What are the common categories of seamless steel pipes & tubes?

1. Hot rolled seamless steel pipe
Hot-rolled seamless steel pipe is a seamless steel pipe made by heating the blank to a sufficient temperature through a hot-rolling process, and then passing it through multiple continuous passes. Its advantages are high production efficiency and smooth surface. It is usually used to transport high-temperature and high-pressure gas or liquid.

2. Cold drawn seamless steel pipe

Cold drawn seamless steel pipe is processed from steel pipe blank into seamless steel pipe through cold drawing process. Compared with hot-rolled seamless steel pipes, cold-drawn seamless steel pipes have higher surface smoothness and higher dimensional accuracy, and are suitable for manufacturing various precision mechanical parts and refrigeration equipment.

3. Precision seamless steel pipe
Precision seamless steel pipes are produced through cold drawing processes, which require higher dimensional accuracy and surface smoothness. They are used to manufacture high-precision equipment such as hydraulic systems, aerospace vehicles, and nuclear power plants.

4. Alloy seamless steel pipe
Alloy seamless steel pipe is a steel pipe with high temperature, high pressure, high strength and high corrosion resistance. It is widely used in petrochemical, electric power, nuclear industry and other fields. According to their alloy composition, they can be divided into different types, such as chromium-molybdenum alloy steel pipes, nickel alloy steel pipes, etc.

5. Stainless steel seamless steel pipe
Stainless steel seamless pipe is a steel pipe with strong corrosion resistance and is widely used in petrochemical, pharmaceutical, food and other fields. According to their different compositions and uses, stainless steel seamless steel pipes can be divided into different varieties, such as austenitic stainless steel pipes, ferritic stainless steel pipes, etc.

In short, seamless steel pipe is an important industrial material suitable for many fields. Different seamless steel pipe categories have their own characteristics and advantages. Choosing the steel pipe suitable for your own use according to your needs can better meet production and use requirements.
