ABSTRACT:
A pipe-inspection system (100) is provided. The system (100) is made up of a transmission cluster (104) incorporating a transmission unit (800) between first and second wheeled guidance units (400), and a reception cluster (104″) incorporating a reception unit (1400) between third and fourth wheeled guidance units (400). Each wheeled guidance unit (400) contains a plurality of wheels (416) radially disposed in each of a plurality of planes (420, 426, 432). Transmission unit (800) contains a transmission device (1004). Reception unit (1400) contains a reception device (1604). The system (100) is compatible with RFEC inspection techniques to inspect a pipeline (102), where transmission and reception devices (1004, 1604) are an RFEC transmitter and receiver, respectively. A lead line (106) is attached to the first guidance unit (400) to move the system (100) in a forward direction (108). Similarly, a trail line (110) is attached to the fourth guidance unit (400″) to move the system (100) in a reverse direction (112).
