[0070] will be referred to below figure 1 and figure 2 An internal pig implemented according to a first embodiment of the present invention will be described. Internal Pig 1 ( figure 1 ) consists of several modules 100 , 300 interconnected by universal joints 12 . Sealed container 110, low frequency transmitter 130 ( figure 2 ), the low frequency receiver 140 and the internal pipeline medium flow control unit 190 are placed in the first module 100; the polyurethane cup 11 ( figure 1 ) placed on the shell of the first module 100. The sealed container 310 is placed inside the second module 300 while a permanent magnet 13 with a steel brush bundle 14 is mounted on the surface of the second module 300, said permanent magnet providing a magnetic flux through the wall of the steel pipeline being diagnosed and through Closure of the steel housing of the second module 300 . Measuring unit 320 and traveling distance meter 410 ( figure 2 ) is also mounted on the surface of the...

Abstract

The invention relates to apparatuses for internal pipe non-destructive control of pipelines. Technical result is increasing of operational reliability of the internal pipe pig based on use of wireless means for transmitting data and control signals between both internal pipe measurement, diagnosis and control means outside the pig and on-board processing and storing means. An internal pipe pig comprises an electronic system of the pig, comprising wireless data transmission means which comprise at least one electromagnetic signal transmitter, measuring and measured data processing means comprising at least one measuring unit and at least one data processing unit, wherein the wireless data transmission means also comprise at least one high-frequency electromagnetic signal receiver for receiving the transmitted data, which is connected to the data processing unit.

Description

technical field [0001] The present invention relates to systems for testing and observing the condition of pipelines, and more particularly to equipment for the non-destructive control of internal pipelines of pipelines, especially oil and gas product pipeline trunks, by making a device in Controlled pipeline passage, the device includes one or more transfer modules that use the pressure of the product conveyed in the pipeline to move in the pipeline, control sensors located on the module body that are sensitive to parameters reflecting the status of the pipeline, and for measuring, An institution that processes, stores and transmits measured data. Background technique [0002] There may be foreign matter in the pipe cavity where the pig is running. During movement of the internal pig, such foreign objects may scratch connecting cables outside the pig body, including cables connecting sensors to data processing devices located within the pig body. [0003] The pig disclose...
