Seamless steel pipe, as an important metal material, is widely used in various fields. Its high strength, corrosion resistance, long life and other characteristics make it popular in the construction, machinery, chemical and other industries. However, there are many types of seamless steel pipes, and different types have different characteristics to adapt to different application scenarios. This article will introduce the classification of seamless steel pipes in detail to help you better understand and choose the steel pipe that suits your needs.
According to different manufacturing processes, seamless steel pipes are mainly divided into two categories: hot-rolled seamless steel pipes and cold-drawn seamless steel pipes. Hot-rolled seamless steel pipes are made through a high-temperature rolling process, and their advantages are high production efficiency and low cost, but relatively low precision. Cold-drawn seamless steel pipes are made through a cold drawing process, and their advantages are high precision and high strength, but the production cost is high.

In terms of the outer diameter and wall thickness of seamless steel pipes, they are mainly divided into thin-walled seamless steel pipes and thick-walled seamless steel pipes. Thin-walled seamless steel pipes are mainly used for structural parts and fluid conveying pipelines, etc., and their advantages are light weight and low cost; while thick-walled seamless steel pipes are mainly used in occasions that bear heavy loads and high pressures, such as bridges, ships, chemical equipment, etc.

According to different uses, seamless steel pipes can be divided into seamless steel pipes for structures, seamless steel pipes for fluid conveying, seamless steel pipes for high-pressure boilers, etc. Structural seamless steel pipes are mainly used for building structures and mechanical parts, etc., and require high strength and durability; seamless steel pipes for fluid conveying are mainly used to convey fluid media such as water, oil, and gas, and require good corrosion resistance and sealing; seamless steel pipes for high-pressure boilers are mainly used to manufacture high-pressure boilers and nuclear reactors, etc., and require high high temperature resistance and high pressure resistance.

Through the introduction of the classification of seamless steel pipes in this article, I believe you have a deeper understanding of seamless steel pipes. When choosing seamless steel pipes, it is necessary to comprehensively consider the actual needs and application scenarios and choose the appropriate type and specification of steel pipes. At the same time, it is also necessary to pay attention to the quality and reliability of steel pipes to ensure safety and long-term use.
