The invention provides an industrial pipe detecting device, and relates to the field of industrial detecting equipment. The industrial pipe detecting device comprises a connecting rod, wherein the left side of the connecting rod is fixedly connected with a transmission device; a knob is arranged on the right side of the connecting rod; a first rotating shaft is arranged in the connecting rod; theright end of the first rotating shaft is in transmission connection with the knob; and the left end of the first rotating shaft penetrates through the transmission device and is in transmission connection with a first bevel gear. According to the industrial pipe detecting device, by resetting springs in guiding and fixing devices on the outer side of the connecting rod, telescopic columns can be telescopic, the position of a base is convenient to adjust, thus, pipe bodies with different sizes can be detected conveniently, through the resetting springs, rollers can be firmly attached to the inner walls of the pipe bodies with different sizes, through an anti-corrosion sleeve on the outer side of each roller, the circumstance that the rollers are corroded by residual substances on the innerwall of a pipe body during detecting can be prevented effectively, and the service life of the rollers is prolonged effectively.
