Abstract

Corrosion is one of the common enemies in the oil and gas industry. One of the efforts to prevent corrosion is by implementing proper repair standards, such as ASME PCC-2. This study investigates the repair of piping using the Full Encirclement Steel Reinforcing Sleeves method per ASME PCC-2 with GTAW welding process. The GTAW welding process will be evaluated through several test to determine the characteristic of the weld, including strength, hardness, and absence of defects. Characteristic will be obtained from macroscopic examination, tensile testing, hardness testing, and penetrant testing. In this study, the macros the macroscopic examination resulted in 6 welding passes across 4 welding layers: 1 root, 1 hot, 3 fill, and 1 cap. The tensile testing resulted a maximum tensile strength of 579,97 N/mm2. The hardness testing resulted a maximum hardness of 226 HV located at 12 o’clock. The repair of the API 5L Grade-B pipe was free from linear and rounded indications, resulting in accepted criteria.
