The thermal hardness of carbon steel pipes decreases significantly when the working temperature exceeds 200 degrees, leading to poor wear resistance. Additionally, carbon steel pipes have low hardenability.
Carbon steel pipes also have some disadvantages. For example, compared with stainless steel pipes, carbon steel pipes have slightly worse corrosion resistance. In addition, carbon steel pipes may be susceptible to corrosion or oxidation in certain special environments.
The advantages of carbon steel pipes are low price, high strength, good wear resistance, and wide application range; while the disadvantages are susceptibility to corrosion and heavy weight, so in certain environments, it is necessary to strengthen protective measures to extend the service life.
Carbon steel also has many models. In addition, carbon steel will rust if it is not coated with anti-rust oil or painted, which is affected by environmental factors.
Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes.
Hot-rolled carbon steel pipes are divided into general steel pipes, low- and medium-pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
In addition to general steel pipes, low- and medium-pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (drawn) carbon steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes, and special-shaped steel pipes.
