Purpose The purpose of this paper is to describe the reviews of past research work on various in-pipe robotic systems and their operations. This investigation has been focussed on the implemented methodologies for performing in-pipe cleaning and inspection tasks. Design/methodology/approach This work has been concentrated on review of various sensors used in robots to perform in-pipes inspection operation for determining flaws/cracks, corrosion-affected areas, blocks and coated paint thickness. Various actuators like DC motors, servo motors, pneumatic operated and hydraulic operated are discussed in this review analysis to control the motion of various mechanical components of the robot. Findings In the current analysis, categorisation of various pipe cleaning robots according to their mechanical structure has been addressed. A lot of information has been gathered regarding the control of in-pipe robots for performing inspection and cleaning tasks. Originality/value In this paper, various in-pipe cleaning and inspection techniques have been studied. Necessary information provided regarding different types of in-pipe robots like PIG, wall-pressed, walking, wheel and inchworm. This investigation provides a through literature on various types of sensors like ultrasonic, magnetic, touch, light amplification by stimulated emission of radiation, X-ray, etc., that have been used for inspection and detection of flaws in the pipe.

“…Currently, many companies are working on product development and field experiments. A literature survey revealed that few papers have studied the dynamic behaviour of feeler pigs in detecting internal corrosion in gas and oil pipeline, especially with respect to the detection probe (Li et al, 2015;Nguyen et al, 2001a, b). A feeler pig depends on the probe to detect the corrosion, and the detection precision is closely related to the movement process of the probe sweeps across the corrosion.…”

“…The EC method requires deep magnetic penetration in ferrous pipelines, and the major drawback is the spacing problem, which occurs while mounting the sensor array on the circumference of the smart pig [32,33]. In addition, recently, a few ILI methods have also been developed for the inspection of pipelines such as closed-circuit television (CCTV) [34] and mechanical contact probe (MCP) [35]. In the case of the CCTV method, the high power supply and lack of visibility inside the long pipelines are the drawbacks [36].…”

Corrosion is considered as one of the most predominant causes of pipeline failures in the oil and gas industry and normally cannot be easily detected at the inner surface of pipelines without service disruption. The real-time inspection of oil and gas pipelines is extremely vital to mitigate accidents and maintenance cost as well as to improve the oil and gas transport efficiency. In this paper, a new, non-contact optical sensor array method for real-time inspection and non-destructive evaluation (NDE) of pipelines is presented. The proposed optical method consists of light emitting diodes (LEDs) and light dependent resistors (LDRs) to send light and receive reflected light from the inner surface of pipelines. The uniqueness of the proposed method lies in its accurate detection as well as its localization of corrosion defects, based on the utilization of optical sensor array in the pipeline, and also the flexibility with which this system can be adopted for pipelines with different services, sizes, and materials, as well as the method’s economic viability. Experimental studies are conducted considering corrosion defects with different features and dimensions to confirm the robustness and accuracy of the method. The obtained data are processed with discrete wavelet transform (DWT) for noise cancelation and feature extraction. The estimated sizes of the corrosion defects for different physical parameters, such as inspection speed and lift-off distance, are investigated and, finally, some preliminary tests are conducted based on the implementation of the proposed method on an in-line developed smart pipeline inspection gauge (PIG) for in-line inspection (ILI) application, with resulting success.
