There is a great difference between a thick-walled steel pipe and a thin-walled steel pipe in terms of wall thickness. If the diameter of the steel pipe wall is greater than 0.02, we generally call it a thick-walled steel pipe. Thick-walled steel pipes have a very wide range of applications. Owing to their thicker pipe walls, they can withstand greater pressure. Generally, it can serve as a material for hollow parts to withstand pressure and use on important pipelines. Specifically, it can be utilized as a structural pipe, petroleum geological drilling pipe, petrochemical pipe, and so on. When using thick-walled steel pipes, relevant laws and regulations must be applied. Therefore, pipes of different specifications must be used for diverse purposes. This also provides an essential prerequisite for the use of thick-walled steel pipes, especially when transportation is dangerous. In the case of flammable media, it is necessary to find steel pipes of appropriate specifications to effectively prevent accidents.
Thick-walled steel pipes can be widely used in various heavy industries according to their separate models and specifications. Therefore, the development of thick-walled steel pipes is also worth looking forward to receiving. Thick-walled steel pipes are mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. For liquid transportation: water supply and drainage. For gas transportation: coal gas, steam, liquefied petroleum gas. For structural purposes: piling pipes and bridges; pipes for the docks, roads, and building structures.
