Thick-walled steel pipes and thin-walled steel pipes have a big difference in the thickness of the pipe wall. The diameter of the steel pipe wall is greater than 0.02, we generally call it thick-walled steel pipe. Thick-walled steel pipes have a very wide range of applications. Due to their thicker walls, they can withstand higher pressures. It can generally be used as a material for hollow parts, used to withstand pressure, and used on important pipelines. Specifically, it can be used as a structural pipe, petroleum geological drilling pipe, petrochemical pipe, and so on. The use of thick-walled steel pipes should also follow relevant laws and regulations. Therefore, pipes of different specifications should be used for different purposes, which also provides an important premise for the use of thick-walled steel pipes, especially when transporting is more dangerous. When flammable media are used, it is necessary to find steel pipes of suitable specifications, to effectively prevent accidents.
Thick-walled steel pipes can be widely used in various heavy industries according to their different models and specifications. Therefore, the development of thick-walled steel pipes is also worth looking forward to. Thick-walled steel pipes are mainly used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. For liquid transportation: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structure: for piling pipe, for bridge; for wharf, road, building structure, etc.
