📝 Overview

The Pipeline Wall Thickness Calculator determines the required minimum wall thickness for pipelines, based on design pressure, diameter, material strength, and code requirements. Unit selection and code-specific factors are built in, with clear pass/fail status for code compliance.

🧾 Inputs

  • Design Pressure: bar, psi, MPa (selectable)
  • Outside Diameter: mm, inches (selectable)
  • SMYS (Yield Strength): MPa, psi (selectable)
  • Design Factor (F): Auto-filled by code, editable
  • Weld Joint Factor (E): Auto-filled by code, editable
  • Temperature Derating Factor (T): Auto-filled by code, editable
  • Corrosion Allowance: mm, inches (selectable)
  • Design Code:
    • ASME B31.3
    • ASME B31.4
    • ASME B31.8
    • API 1110
  • Output Thickness Unit: mm, inches

🧮 Calculations

  • All inputs are internally converted to SI units for consistency.
  • The main equation (per code) is: ttextrequired=fracPD2FES/T+CAt_{\\text{required}} = \\frac{P D}{2 F E S / T} + CAttextrequired​=fracPD2FES/T+CA
    • PPP: Design pressure (MPa)
    • DDD: Outside diameter (mm)
    • SSS: Specified Minimum Yield Strength (MPa)
    • FFF: Design factor (per code)
    • EEE: Weld joint factor
    • TTT: Temperature derating factor
    • CACACA: Corrosion allowance (mm)
  • The plugin flags acceptance (✅) if all safety/design factors meet code defaults; otherwise, it prompts review (⚠️).
