      public void calculate()
      Run all casing design calculations.

      1. Update material properties from grade lookup
      2. Calculate wall thickness per ASME VIII Div. 1 UG-27
      3. Calculate MAWP
      4. Calculate hydrostatic test pressure per UG-99

      8. If horizontally-split: calculate split-line bolt design
      9. If barrel: calculate outer/inner barrel sizing
      10. Perform NACE MR0175 compliance check

    • updateMaterialProperties

      private void updateMaterialProperties()
      Update material properties from grade lookup using built-in data tables.

      Looks up SMYS, SMTS, allowable stress, density, thermal expansion, and elastic modulus for the specified material grade from ASME II Part D data.

    • calculateWallThickness

      private void calculateWallThickness()
      Calculate required casing wall thickness per ASME Section VIII Div. 1 UG-27.

      For cylindrical shells under internal pressure:

      $t = \frac{P \times R}{S \times E - 0.6 \times P}$

      where P = design pressure, R = inner radius, S = allowable stress, E = joint efficiency.

    • roundUpToStandardThickness

      private double roundUpToStandardThickness(double thicknessMm)
      Round up wall thickness to nearest standard plate thickness.
      Parameters:
      thicknessMm - minimum required thickness in mm
      Returns:
      next standard thickness in mm

    • calculateMAWP

      private void calculateMAWP()
      Calculate Maximum Allowable Working Pressure (MAWP) per ASME VIII.

      MAWP is back-calculated from the selected wall thickness. This is the nameplate rating.

    • calculateHydroTestPressure

      private void calculateHydroTestPressure()
      Calculate hydrostatic test pressure per ASME VIII UG-99.

      For Div. 1: Test pressure = 1.3 x MAWP x (stress ratio at test temp / stress ratio at design temp).

      For API 617 compressors, minimum 1.5 x design pressure is typical.

    • selectFlangeRating

      private void selectFlangeRating()
      Select and verify flange rating per ASME B16.5 (NPS 1/2-24) or B16.47 (NPS 26-60).

      Selects the minimum flange class that exceeds the design pressure at the design temperature. Temperature derating is applied per the ASME B16.5 pressure-temperature tables.

    • calculateNozzleAllowableLoads

      private void calculateNozzleAllowableLoads()
      Calculate allowable nozzle forces and moments per API 617 Table 3.

      API 617 specifies allowable nozzle loads as a function of nozzle size. For centrifugal compressors, forces are specified for each nozzle connection (suction, discharge, sidestream).

      Simplified correlation based on API 617 8th Ed. Table 3:

      • Allowable force scales approximately with D^1.5
      • Allowable moment scales approximately with D^2.5

    • calculateThermalGrowth

      private void calculateThermalGrowth()
      Calculate thermal growth and differential expansion between casing and rotor.

      Thermal growth is critical for compressor alignment. The casing grows from the anchor point (typically drive end bearing), and the rotor grows from its thrust collar. Differential expansion affects internal clearances and must be within acceptable limits.

      $\Delta L = L \times \alpha \times (T_{operating} - T_{ambient})$

    • calculateSplitLineBolts

      private void calculateSplitLineBolts()
      Calculate split-line bolting for horizontally-split casings.

      The horizontal joint must resist the internal pressure force tending to separate the casing halves. The bolt load must overcome both the hydrostatic end force and the gasket seating load.

      The required bolt area is calculated as: $A_{bolt} = \frac{F_{pressure} + F_{gasket}}{S_{bolt} \times N}$

      where $F_{pressure} = P \times D \times L$ (force on split-line), $F_{gasket}$ = gasket seating force, $S_{bolt}$ = allowable bolt stress, N = number of bolts.

    • calculateBarrelCasing

      private void calculateBarrelCasing()
      Calculate barrel casing outer/inner barrel sizing.

      Barrel casings consist of an outer pressure-containing barrel and an inner bundle (cartridge) that slides out for maintenance. The outer barrel is typically a forged cylinder (SA-266) that avoids the split-line sealing issue at high pressures.

    • assessNaceCompliance

      private void assessNaceCompliance()

      NACE MR0175 applies when:

      • Total pressure > 0.4 MPa abs, AND
      • H2S partial pressure > 0.3 kPa (0.05 psia)

      Material requirements per NACE MR0175:

      • Carbon steel: max 22 HRC hardness, SMYS <= 360 MPa
      • Austenitic SS: generally acceptable (304L, 316L)
      • Duplex SS: acceptable with hardness limits
      • Nickel alloys: Inconel 718 acceptable per NACE

    • recommendMaterial
