Flange, pipe and tube calculations, worked to the clause.

Bolt loads, gasket seating, wall thickness, pipe stress and creep life to ASME, API and EN. Every step is shown and every input is kept, so the number you sign holds up when it is checked.

Half-section of an NPS 4 Class 300 weld-neck flange joint, drawn to ASME B16.5, with heavy hex nuts to B18.2.2 and a 3/4-10 UNC thread to B1.1.

Every calculator is worked to its code

They share one register, file their records under the plant and equipment they belong to, and print a report that shows the working.

  • ASME PCC-1 App. OASME VIII-1 App. 2

    The assembly bolt load, the flange and gasket stresses it produces, and a torque sheet for the field.

  • API 574ASME B31.3

    The thinnest wall a pipe span can run at, for pressure and for carrying its own weight.

  • API 579-1 Part 10

    The remaining life of a fired-heater tube from its metal temperature, wall and creep data.

  • API 579-1 Annex 10BWRC 541

    Creep Data AnalyserIn development

    Larson-Miller fits from rupture tests, qualified against the WRC 541 reference alloys.

  • ASME B31.3ASME B31.1ASME B31J

    Pipe Stress AnalysisIn development

    Weight, pressure and thermal load cases on a line you walk down node by node in the app.

What stands behind a result

Every number cites its clause.

A result names the equation and the standard it comes from, so a reviewer can open the book and check it line by line.

Tested against real reports.

Each engine is regression-tested against published worked examples and independent calculation reports before a method is released, and then frozen.

Inputs are kept. Results are not.

A record stores what you entered and recalculates every time it opens, so a saved report can never drift from its inputs.
