Preventing the catastrophic development of an emergency in case of main pipeline integrity failure is the most important task to ensure the safety of the population and prevent significant economic damage. Non-destructive testing, which performs the functions of ensuring technical safety at a hazardous production facility, is the most important element of the industrial safety expertise system. In this paper, the types of pipeline defects and methods for their detection, as well as the types of impact on personnel, which is an important factor, are considered.
The article presents data on the methods for assessing the quality of pipeline welding. The capabilities of various welding quality control methods are compared. And samples of welding defects are provided.
The inspection of the technical condition of pipelines relies on a set of methods, of which the methods of flaw detection and in-line inspection are the most trusted in production. Their use requires the preparation of pipelines for control, which has led to the development and improvement of the software and hardware system for non-contact magnetometric inspection. Unlike the complexes by other authors, our development equally combines the high accuracy of instrumental measurements and the representativeness of the results of their data interpretation.
The article deals with the issues of non-destructive type of technical control. One of the main methods of this control – ultrasonic testing – is considered. The basic instruments of this method and the principles of their operation are described.
The features concerning the application of modern methods of power cable line monitoring, such as pulse reflectometry, partial discharge and arc reflection methods, the impulse current method, are considered. The physical effects forming the basis for the implementation of these control methods are analyzed. The order of necessary operational procedures for the relevant control methods is outlined in a systematic way. It is proposed to use new physical effects to improve quality indicators of control methods.
The article presents the results of the development of an automated diagnostic system for printed circuit boards (ADS PCB) with application of machine vision technology. The hardware of the ASD PCB software is based on the PXI modular platform using the PXI-6239 data acquisition module and the PXI-6509 digital signal generator module.
Scanning contact potentiometry (SCP) method is an electrophysical method of non-destructive testing developed in ElphysLAB laboratory of the National Research Nuclear University MEPhI (Moscow Engineering Physics Institute). It provides effective diagnosis of reactor equipment, ensuring the reliability of measurement results in conditions close to those of work with nuclear materials.
