Abstract

This paper introduces the application of infrared thermal imaging detection technology in the field of special pressure equipment, and conducts application research on the infrared characteristics of corrosion thinning on the inner and outer walls of pressure vessels. The conclusions include: the infrared image features of corrosion thinning pits on the outer wall of pressure vessels are not affected by temperature changes and can maintain relatively consistent detection contrast; Compared with the infrared detection results of corrosion pits on the outer wall of the container, the infrared contrast of corrosion pits on the inner wall is relatively low; The deeper the corrosion pits on the inner and outer walls of the container, the higher the detection contrast. The shallower the corrosion pits on the inner wall, the lower the detection contrast. This phenomenon has been explained. The research results of this article have good guiding significance for the infrared online detection of pressure vessels.
