Steel pipes are essential in the oil and gas industry, serving as well pipes, casing, and oil pipes during drilling operations. With high strength and toughness, they protect well walls against geological pressures and ensure operational safety. Beyond drilling, steel pipes are widely applied in oil and natural gas transmission, storage, and distribution systems, making them the backbone of global energy infrastructure.
