Non-destructive pipe scanner |
摘要 |
A non-destructive examination pipe scanner that employs a main carriage on which a sensor is mounted, a tensioner carriage and an idler carriage. The main carriage and the tensioner carriage are positioned around the pipe at spaced locations and connected on either side by a spring band. The idler carriage is slidably supported by the spring band in between the main carriage and the tensioner carriage. The sensor on the main carriage collects data about a circumferential weld on the pipe as the main carriage drives the tensioner carriage and the idler carriage around the circumference. The tensioner carriage has a variable length connection that adjusts the tension on the spring band to urge the main carriage, idler carriage and tensioner carriage into contact with the surface of the pipe. |
