Application of Acoustic Emission in Control of High-Pressure Pipe Overstraining

Abstract:

Article Preview

The article describes the application of AE technique in control and evaluation of the pipe overstraining process. The trials of overstraining were conducted according to a programme of pipe loading with internal pressure, developed and adjusted to the examined pipe material. In the studies two systems of acoustic emission were used, viz. PAC Mistras 2001 and Vallen AMSY. The procedure adopted in the development of evaluation criteria based on an analysis of the recorded acoustic events was described. Next, the criteria of evaluation were presented. The effectiveness of the applied method, the validity of the adopted criteria, and the consistency of the obtained quantitative results were checked during tests performed by other NDT methods. A comparative analysis was made to serve as a complementary tool in final evaluation of the pipe overstraining process done by AE technique.
