Assessment of destruction conditions of the long-term operation gas pipeline
Journal Title: Вісник Тернопільського національного технічного університету - Year 2017, Vol 87, Issue 3
Abstract
For the long-term operation of main oil and gas pipeline steels the method of estimation the critical crack growth resistance of pipeline steels using experimentally obtained diagram of „force-deflection“ specimens destruction was proposed. The sizes of through critical cracks have been calculated and the initial sizes and the shape of the crack-like defects for the investigation of main gas and oil pipelines were evaluated. The obtained data can be a basis for the interpreting of the detected crack-like defects for the technical diagnostics.
