Application Summary AI generated
GB/T 9808-2008 specifies the dimensions, technical requirements, and testing methods for seamless steel tubes used in drilling operations. It is primarily applied in geological exploration, oil and gas extraction, and water well drilling, where the tubes serve as drill rods, casings, or core barrels. The standard ensures the tubes meet strength, pressure, and durability criteria for safe and efficient drilling under harsh subsurface conditions.
