Interactive 3-D simulation tools for process and mechanical engineers. Change the inputs, watch the equipment respond, and see the code calculation behind every number. Built for students who want to see how design works, and for working engineers who want a quick, honest check.
Pressure Vessel Shell Lab
A 3-D horizontal separator you can pressurise. Change design pressure, diameter, corrosion allowance, material and joint efficiency, and get the UG-27 thickness, the plate to order, the MAWP and the hydrotest pressure. Run a hydrotest and watch the shell’s stress rise.
ASME VIII DIV. 1 · UG-27 · UG-99 OPEN THE LAB → ● LIVE · FREENozzle Reinforcement Lab
Put a nozzle into the V-100 shell and balance the UG-37 areas: shell, neck, welds and pad. Change the size and schedule, check the UG-45 neck, and size the reinforcing pad to the minimum.
ASME VIII DIV. 1 · UG-37 · UG-45 OPEN THE LAB → FREE CORE · PRO EXTRASHSep-Designer+ · separator sizing
Size a horizontal 2- or 3-phase separator: gas and liquid capacity, retention time, droplet settling, demister and nozzle checks, an operating envelope and a 13-sheet datasheet report.
API 12J · RP 14E · GPSA SEE THE TOOL →Impulse Line Lab
Mount a pressure transmitter above or below the tapping and watch a wet leg fill. See the reading error grow against the loop’s total probable error.
API RP 551 · NAMUR NE 43Separator Droplet Lab
Release droplets into a separator’s gas space and see which ones settle and which carry over, against the Souders-Brown limit.
