The bending fatigue fracture properties of G105 drill pipe body materials and the influence of H sub(2) S corrosion and notch on the specimen bending fatigue performance were studied using the domestic PQ-6 type rotating bending fatigue testing machine. The fracture surfaces of smooth specimens, not...
