AUTOMATED CONTROL OF PARENT METAL OF PIPE WALLS AT TRUNK PIPELINES WITH THE NONCONTACT ULTRASONIC SCANNER-FLAW DETECTOR A2075 SoNet

摘要

The Gazprom gas transport system includes more than 160 thousands kilometers of pipelines. The most part of it was built in the seventies-eighties of the last century. Aging of basic assets at the linear part of trunk pipelines is about 60%. [1] Average actual lifetime of pipelines is about 30 years. Long service life of trunk pipelines results in increasing number of flaws detected at regular diagnostic tests. One of the ways to prolong lifetime of a pipeline is a general overhaul.
