ASME-code mechanical ratings, fed straight from the process.
Design pressure, temperature, and vapor rates come out of the converged flowsheet — not a hand-typed datasheet. Get a wall-thickness and nozzle check the moment the simulation solves.
Compression, cooling, letdown, and pipeline transport — every stage feeds the mechanical rating with real, converged process conditions.

Engine capabilities
What this solver actually handles, not a feature-list promise.
Shell and head wall thickness
UG-27 cylindrical shell thickness and UG-32 2:1 ellipsoidal head thickness from the converged design pressure and temperature, plus UG-28 external-pressure/vacuum wall thickness for vessels that see vacuum service.
Nozzle reinforcement and wind loading
UG-37 opening reinforcement check flags whether a nozzle needs a reinforcing pad, and UG-22 adds wind-bending thickness for tall columns — both driven by the same stream conditions the flowsheet already solved.
Tube vibration and fatigue screening
Tube natural frequency vs. vortex-shedding frequency, a Connors fluid-elastic instability check, and an acoustic-resonance coincidence screen for shell-and-tube exchangers — plus a Basquin-curve fatigue check and TEMA tube-count sizing.
Nozzle-load envelope for downstream checks
An allowable nozzle-load envelope (axial, shear, bending, torsion) exports the numbers a WRC-107 or CAESAR II piping-stress review needs next — the simulation hands off real loads instead of a placeholder assumption.
Compressor and pump hydraulics
Polytropic compression and centrifugal-pump duty computed directly from the converged process stream — the same numbers that feed the ASME rating, not a separately re-modeled datasheet.
Pipeline and letdown hydraulics
Pressure-drop and valve letdown hydraulics on the converged flowsheet's actual flow, composition, and phase — no separately maintained line-sizing spreadsheet.
Scripted from Python
The same engine, called from the flowsim SDK.
from flowsim.sdk import FlowSimClient
client = FlowSimClient()
sim = client.create_simulation("Gas conditioning train", flowsheet)
client.run(sim["id"])
sheets = client.datasheet(sim["id"]) # TEMA exchanger + API pump/compressor datasheetsSee it on your own process
