CSA Z662.19 provides equations limiting the circumferential and longitudinal stresses in steel pipelines. The equations depend on whether the pipe is restrained from expanding or contracting in the longitudinal direction or not. Given the pipe properties and field conditions, this page performs the required checks according to sections 4.3.5.1, 4.7, and 4.8.
