Oil drill pipe is a seamless steel pipe made from hot-rolled or cold-drawn geological drilling steel. It is primarily used in the oil and geological drilling fields and includes drill pipe, core barrels, casing, and drill collars.
Oil
drill pipe is a seamless steel pipe made from hot-rolled or cold-drawn geological drilling steel. It is primarily used in the oil and geological drilling fields and includes drill pipe, core barrels, casing, and drill collars. This pipe must withstand tensile, compressive, torsional, impact loads, and mud abrasion in environments thousands of meters underground, requiring high strength, wear resistance, and impact toughness.
Drill pipes are categorized by end treatment as internally upset or externally upset. Connection options include threaded and butt-welded joints, with outer diameters ranging from 60mm to 139.7mm.
Oil drill pipe is used in oil and geological drilling. Operating at depths of thousands of meters underground, the conditions are extremely complex. During operation, the pipe is subjected to tensile, compressive, torsional, and impact loads, and its walls are abraded by mud and rock particles. Therefore, the pipe must possess sufficient strength, hardness, wear resistance, and impact toughness.
