摘要： Electromagnetic waves are driven in the pipe to be inspected in the piping system by a transmitting antenna of a transmitter, to be propagated in the pipe; while a receiving antenna of a receiver is moved outside the pipe along the pipe, to receive leaking electromagnetic waves for inspecting elements of the piping system, and the location concerned of each element of the piping system to be inspected is detected in reference to the location of the receiving antenna where the level of electromagnetic waves received by the receiver becomes a peak. The locations to be inspected are the damaged portions such as holes formed by corrosion, cracks, etc. in the pipes, and the locations of joints, etc. It is also possible to move the transmitting antenna outside along the pipe, while arranging the receiving antenna at proper place in the pipe. Furthermore, it is also possible to move both the transmitting antenna and the receiving antenna in synchronization to effect the above inspection. When either the transmitting antenna or the receiving antenna is moved, the frequency of electromagnetic waves can be a frequency propagated in the pipe or can also be lower than the cut-off frequency. On the other hand, the antenna can be made long and kept in the pipe, to use a frequency lower than the cut-off frequency without moving the antenna

摘要： A method of inspecting an abnormality occurring inside a pipe to be inspected, and an apparatus for practicing the method, which includes the steps of transmitting an electric radio or radio frequency (RF) wave having a predetermined frequency from an antenna of a transmitter located at a predetermined position inside the pipe, receiving the transmitted RF wave by an antenna of a receiver located at a predetermined position inside the pipe, and discriminating a characteristic of the received RF wave. The characteristic of the received RF wave can be the intensity of the RF wave, and an attenuation amount is detected in a first example. Alternatively, the characteristic of the received RF wave may be the time required to reflect the transmitted RF wave and receive it with the receiver, and the time interval between transmission of the RF wave and reception of the reflected RF wave is measured in this alternative.

摘要： An intrapipe work robot apparatus includes an intrapipe work robot and an operation unit. The intrapipe work robot is inserted into a pipe so as to perform a work while performing automotive traveling in the pipe. The operation unit designates travel and other actions of the robot externally of the pipe. The operation output signal is transmitted from at least the operation unit to the intrapipe work robot through a radio communicating device having special antenna units.

摘要： A method of measuring the inner diameter of a pipe includes the steps of continuously transmitting RF waves of a predetermined frequency band from an antenna of a transmitter located inside of the pipe to be inspected, receiving the RF waves with an antenna of a receiver located inside the pipe, the antenna of the receiver being spaced apart from the antenna of the transmitter by a predetermined distance, detecting a frequency at a change point where an intensity of the received RF wave changes greatly, and substituting the frequency at the change point into a formula: d=c/1.706f (wherein d is the inner diameter of the pipe, c is the velocity of light, and f is the frequency at the change point) which shows the relation between the inner diameter of the pipe and the frequency to obtain a minimum inner diameter of the pipe.

摘要： An apparatus for measuring an inner diameter of a pipeline is incorporated into a passage pig for checking passableness through the pipeline or a cleaning pig for cleaning within the pipeline, the passage pig and the cleaning pig including at least one seal cup sealably sliding along an interior surface of the pipeline. The apparatus includes a travel distance measuring unit for measuring a travel distance of the passage pig or the cleaning pig within the pipeline, a swing angle detector for detecting a swing angle of a pig body during the travel distance measurement, a displacement detector for individually detecting a radial displacement of the peripheral portion of the seal cup at a number of points along an entire circumference during the travel distance measurement, a computing unit for computing an output from each of said means, and a recording means for recording an output from the computing unit.
