Thick-walled hot-rolled pipe No. 20 steel seamless steel pipe is an important material widely used in industrial and construction fields. Its excellent mechanical properties and corrosion resistance make it excellent in a variety of high-pressure, high-temperature and corrosive environments. This article will introduce in detail the manufacturing process, performance characteristics, application fields and market prospects of thick-walled hot-rolled pipe No. 20 steel seamless steel pipe.
First, the manufacturing process.
The manufacturing process of thick-walled hot-rolled pipe No. 20 steel seamless steel pipe mainly includes steelmaking, rolling, perforation, heat treatment and other steps. First, a high-quality No. 20 billet is obtained through the steelmaking process, and then the billet is rolled into a tube billet through a hot rolling mill. Next, the tube blank is perforated into a capillary tube by a perforator, and the capillary is rolled into a seamless steel pipe by a rolling mill. Finally, the structure and properties of the steel pipe are adjusted through the heat treatment process to meet different use requirements.
Second, performance characteristics.
Thick-walled hot-rolled pipe No. 20 steel seamless steel pipe has many excellent performance characteristics. First of all, it has high strength and good plasticity, and can maintain stable mechanical properties in high temperature and high pressure environments. Secondly, the steel pipe has good corrosion resistance and oxidation resistance, and can be used for a long time in harsh corrosive environments. In addition, the thick-walled hot-rolled pipe No. 20 steel seamless steel pipe also has good weldability and processability, which is convenient for various connection and processing operations.
Third, the field of application.
Thick-walled hot-rolled pipe No. 20 steel seamless steel pipe is widely used in oil, natural gas, chemical industry, electric power, construction and other fields. In the oil and gas transmission, the steel pipe is able to withstand high pressures and corrosive media, ensuring safe transportation. In the chemical industry, thick-walled hot-rolled pipes 20 steel seamless steel pipes can be used to manufacture various reactors and heat exchangers and other equipment. In the power sector, the tube is used to make key components such as boilers, steam turbines, and generator sets. In addition, thick-walled hot-rolled pipe No. 20 steel seamless steel pipe can also be used for the support of building structures and the construction of bridges.
