Abstract: In-pipe intelligent isolation plugging tools (IPTs) are crucial in pipeline maintenance. During the plugging process, the flow field around the IPT changes drastically, resulting in vibration and instability of the plugging ...

Abstract: The distribution of internal defects in large-diameter steel pipes can be complicated. Due to the harsh working environments involved, the manual grinding method for correcting such defects is inaccurate, inefficient, and ...

Abstract: Buried pipelines play a crucial role in the transportation of oil and gas. However, they are invisible and prone to corrosion accumulation, leading to potential leakage that can impact safety and the economy. Currently, ...
