Abstract:
A method of testing a tubular member and selecting tubular members for suitability for expansion by subjecting a representative sample the tubular member to axial loading, stretching at least a portion of the tubular member through elastic deformation, plastic yield and to ultimate yield, and based upon changes in length and area calculating an expandability coefficient indicative of expandability of the tubular members and selecting tubular members with relatively high coefficients indicative of good expandability.
