Server-side calculations against current ASME pipe, flange, and material data

Process piping and pressure equipment calculations, each run on current ASME data tables. Inputs and outputs are visible on the page. Calibration constants, validation logic, and reference data stay on the server. Results are suitable for design intent and citation, not as a substitute for an engineer-of-record stamp.

These tools complement the cyclone and separator calculators, which run entirely in the browser using published correlations.
