Pipeline hoop stress calculation
WebbThese forces are calculated based on the product flowing through the line (e.g. crude oil, natural gas, etc.) and the temperature and pressure range for which the pipeline is being … Webb13 mars 2024 · 1.1.1 Basic Stress Concepts. Normal stresses: Normal stresses are those acting in a direction normal to the face of the crystal structure of the material, and may be either tensile or compressive in nature. (In fact, normal stresses in piping tend more to tension due the predominant nature of internal pressure as a load case.)
