A method of augmenting the mechanical properties of a pipeline section comprises the steps of (1) identifying a pipeline section which requires verifiable data and analysis to calculate a safe operating pressure; (2) wrapping the external surface of the identified pipeline section with two or more convolutions of homogeneous isotropic thin steel augmentation bands; (3) adhering the convolutions together via a structural adhesive; and (4) determining the pressure-containing ability of the resultant augmented pipeline section, while simultaneously creating the inputs to determine at least one additional useful engineering design input parameter of the augmented pipeline section, required to calculate and validate a safe operating pressure.

Augmentation of mechanical properties of high pressure pipe

A system for mapping a surface defect in an electrically-conducting material by measuring a change in the resonance of the material includes a flexible printed circuit board and a two dimensional array of transducers printed on the flexible circuit board, wherein each element of the array includes two transducer coils in a paired arrangement. A receive circuit connected to the coils is tuned to a resonant frequency, and the transducer coils operate in a send/receive mode. In another feature of the invention, there are means for converting a change in measured resonance to a visual display of the depth and width of the surface defect.
