Center Exposer Used in Pipeline Inspection for High Pressure Hydrogenation Unit

During the fabrication of 200×104/a hydrocracking unit,RT to the thick wall pipelines that service under high pressure high temperature could not ensure the fabrication schedule,so the center exposer was developed and used.Practice shown that comparing with double-wall signal-imagine method,the synthetic efficacy was enhanced 10 times after using the center exposer to the pipelines that service under high pressure high temperature.The development of center exposer providing an efficient and maneuverabile nondestructive testing device for the similar engineering equipment.
