Abstract

To ensure safety of Rongsheng’s ultra-high voltage ram blowout preventer shell, ultrasonic testing was done on the 5mm INCONEL 725 layer on its inner cavity and diameter. This layer enhances wear/corrosion resistance and local strength; key targets are in-layer, unbonded, and subsurface defects. Due to thinness and special structure, testing was from the surfacing side: using dual-crystal straight/angle probes, with T1/T2 and custom blocks for calibration, and ground probes for better curved coupling. The PXUT-350C enabled full inspection, effectively identifying defects, ensuring quality, and providing a solution for similar thin-walled surfacing.
