Title:
圧力下の流体の入った管路の挙動を監視するための方法および装置
Document Type and Number:
Japanese Patent JP4406638
Kind Code:
B2
Abstract:
The process involves supplying information of circumferential dilation of a pipeline by static monitoring of predefined number of singular or flow zones. Information of modes and frequencies of vibration of the pipeline is supplied by dynamic monitoring of the pipeline. The dilatation and vibration information are processed to obtain effective rigidity of the pipeline and a measured residual section of steel. An independent claim is also included for a system for monitoring the behavior of a pipeline containing pressurized fluid.
