Compliance

Results you can trace, line by line.

Each result in PlutoHX carries its formula, the inputs it used, the steps in between, and the code rule it comes from.

The six steps of a PlutoHX design as cards, from the thermal datasheet to the finished design, with step 3, review and approve by the owner or creator, highlighted as the human check. — Open the drawing at full size

What a result looks like

One line of a calculation package.

The shell of the teaching example, as a result is laid out: the rule, the formula, the inputs, the working, and the outcome.

Shell, internal pressureASME Section VIII, Division 1, UG-27(c)(1)

Formula

t = P R / (S E - 0.6 P)

Inputs

P	300 psi	design pressure
R	20.125 in	inside radius, corroded
S	20,000 psi	SA-516 Grade 70, ASME Section II, Part D
E	0.85	joint efficiency, spot radiography (UW-12)
c	0.125 in	corrosion allowance (UG-25)

Working

t = 300 × 20.125 / (20,000 × 0.85 - 0.6 × 300)
t = 6,037.5 / 16,820 = 0.359 in
t + c = 0.484 in

Result

Plate provided1/2 in

Meets the requirement

Rule limits: t not over R/2, P not over 0.385 S E.

Three moments of review

Before, during, and after the design.

Before: the data is approved
The engineer reviews and approves the imported data, and confirms the assumptions, before PlutoHX designs anything.
During: live checks
Code compliance checks, design warnings, and feasibility checks run while the design takes shape, with a friendly note where something needs attention.
After: the calculation package
The package lays out each result with its working, for the client, the lead engineer and the Authorized Inspector.

For the records

Validation and requirements, in writing.

Among the reports PlutoHX generates are the non-destructive examination (NDE) and post-weld heat treatment (PWHT) requirements of the design, and a software validation report for the records of the project.
