method for intensifying the collapse resistance of a hollow metallic tubular product, and, hollow metallic tubular product performed and radially compressed.

摘要

a method for improving the collapse resistance of metal tubular products is described. the method comprises identifying the types of stress that can be applied in order to change the residual stress profile of metal tubular products, such as those that have completed a performance process, and results in a residual stress profile that improves collapse resistance . the metal tubular product is subjected to radial compression processing to control the residual stress profile and intensify the resistance to collapse. the radial compression process can be used after the tubular product has been subjected to a performance process.
