About EN 13480
EN 13480 is the European standard for metallic industrial piping, covering design, materials, fabrication, inspection, and testing of piping systems.
Formula Used
e = (p × D) / (2 × f × z + p)
Variables
- e — Minimum wall thickness (mm)
- p — Calculation pressure (bar or MPa)
- D — Outside diameter (mm)
- f — Nominal design stress (MPa)
- z — Weld joint factor
- c — Corrosion/erosion allowance (mm)
