About this document
Cracking Causes in Thick-Walled Steel Pipes by Zhalgas is a document available to read on EtoBox.
There are several reasons for longitudinal cracking in thick-walled seamless steel pipes, primarily due to large residual stresses from the cold drawing process. Residual stresses near the outer surface, especially tangential tensile stresses, promote crack formation and propagation. While microcracks are inevitable, cracks occur when tensile stresses from residual stresses exceed the material strength. Proper annealing can help relieve residual stresses and reduce cracking risks.
