摘要： A pipe inner surface inspection apparatus that can accurately inspect the inlet portion of a pipe is provided. The pipe inner surface inspection apparatus provides a guide unit (13) that is inserted into a pipe head (5); stabilizers (15) (17) that are installed on the guide unit (13) with gaps therebetween in the axial direction and substantially align the axial center of the pipe head (5) and the axial center of the guide unit (13); a drive shaft (19) that moves in an axial direction and around an axial center and engages the guide unit (13); and an inspection portion (21), for inspecting the condition of the inner surface of a pipe head (5), is rotatably installed on pivot shafts extending in a direction normal to a plane perpendicular to the axial center of the pipe head (5) at the center position in an axial direction at a rearward position more separated in an axial direction than the portion of the guide unit (13) sandwiched between the stabilizers (15) (17) and the stabilizer (17) side end portion is positioned at the axial center side, and in an unloaded state, is energized so as to always move within a range in which the diameter of the outer peripheral side position of the stabilizer (17) side end portion is smaller than the inner diameter of the pipe head (5).

摘要： This invention prevents the failure of detection for horizontal and oblique lift-offs in a probe for an eddy current flaw detection test. A plurality of probes are provided, and each probe includes four detection coils. Two adjacent eddy current flaw detecting probes commonly own (share) one of the four coils. The detection coils are connected to a bridge circuit for picking up a flaw signal. The detection coils are adjusted so that interlinkage magnetic fluxes generated inside the detection coils by the eddy current become equal. An excitation coil for inducing the eddy current in a test piece by AC driving can be disposed over the detection coils. The center of the excitation coil is positioned on the center axes of the detection coils. An oscillator for applying an AC current to this excitation coil is connected to the coil.
