Seamless steel pipe is a metal material with excellent properties such as high strength, corrosion resistance and high temperature resistance, which is widely used in petroleum, chemical industry, electric power, machinery and other fields. Among them, 20 seamless steel pipe is a common seamless steel pipe with good comprehensive performance, which is widely used in the manufacture of pipelines and containers for petrochemical equipment. The following will be introduced from the classification of seamless steel pipes, the characteristics and application fields of 20 seamless steel pipes.
1. Classification of seamless steel pipes.
Seamless steel pipes can be divided into two types: hot rolled and cold drawn according to the manufacturing process. Hot-rolled seamless steel pipes are made by high-temperature rolling, which has the characteristics of smooth surface and high dimensional accuracy, and is suitable for manufacturing large-diameter pipes and containers. Cold-drawn seamless steel pipes are made by low-temperature stretching, which has the advantages of high strength and high toughness, and is suitable for manufacturing small-diameter pipes and containers with complex shapes.
2. 20 Characteristics of seamless steel pipes.
Seamless steel pipe is a high-quality carbon steel material with excellent comprehensive properties, which is suitable for manufacturing pipes, containers, etc. of various petrochemical equipment. Its key features include:
