About

Xingji Du is a leading researcher in the field of non-destructive testing (NDT) and robotic maintenance for industrial pressure vessels and pipelines. His work focuses on developing advanced inspection and repair technologies for critical infrastructure, particularly spherical tanks and pressurized pipe systems. Du’s key contributions include pioneering ultrasonic inspection techniques for pipe elbows, where he advanced both traditional and phased array methods for in-line corrosion detection (5 citations). He also designed a wall-climbing robot for Time-of-Flight Diffraction (TOFD) welding seam inspection on spherical tanks (4 citations), addressing the challenges of manual scaffolding and hazardous working conditions. Beyond inspection, Du has innovated robotic systems for inner wall derusting and grinding of pressure pipelines (2 citations), as well as a specialized wall-climbing grinding robot for large spherical tank weld preparation (2 citations). His integrated approach—combining robotics, NDT, and surface treatment—has significantly improved safety, efficiency, and reliability in the maintenance of energy storage and transport infrastructure. Du’s work is essential for ensuring the structural integrity of facilities in the petroleum and liquefied natural gas industries.
