Jereh tubing inspection system (JTIS) is mainly for detection of outer diameter and ovality of coiled tubing string and inspection of such defects as wall scratches, holes and pits via MFL during CT operation.
High Interchangeability: It is applicable for coiled tubing of all specifications by simply changing the probes.
High Accuracy: Multi-channel sensors and data fusion technology are employed realizing real time inspection and bringing high efficiency and accuracy.
Simple & Reliable: Simple installation eliminates the process of lifting and tubing threading; non-contact detection prevents from oil dirt or dust caused inspection inaccuracy; CT can be effectively protected during inspection.
Energy-saving: Permanent magnet unnecessitates excitation source.
