Steel pipe drilling is a common metal processing method, commonly used in the production of pipelines,
bridges, buildings, and mechanical equipment. Steel pipe drilling can be achieved through various methods,
including mechanical drilling, flame cutting, laser cutting, and water cutting. The selection of an appropriate
method depends on the material, size, and required pore size of the steel pipe. When drilling steel pipes,
it is necessary to pay attention to safety and avoid damaging the surface and internal structure of the steel pipes.
