Drill pipe failure is a crucial issue in the oil and gas drilling industry, particularly in directional and horizontal drilling operations. This study aims to analyze the failure of drill pipes under various loading conditions at Rig PDSI#42.3/N1500-E. The investigation includes an assessment of mechanical properties, material composition, and structural integrity based on API 5DP standards. The research utilizes laboratory testing, including tensile testing, impact testing and hardness testing. The results indicate that the drill pipe failure is primarily attributed to intergranular brittle fracture caused by a combination of tensile stress, high-temperature exposure, and extreme pressure conditions. The findings reveal that while the material conforms to API 5DP Grade G105 specifications, localized embrittlement occurs in the fracture area, weakening the grain boundaries and leading to structural failure. Von Mises stress analysis further supports the failure mechanism, demonstrating that excessive tensile loads contributed significantly to the pipe's degradation. To mitigate similar failures, it is recommended that drill pipes undergo predictive maintenance through regular inspection cycles before exceeding the 1,500-hour operational threshold. Additionally, optimizing material selection with higher resistance to high-pressure and high-temperature conditions can enhance the durability of drill pipes in extreme environments. Future research should integrate numerical simulations with real-time monitoring techniques to develop a more robust failure prediction model.​
