What Crash Energy Absorption — Front Crumple Zone calculates
Crash Energy Absorption — Front Crumple Zone is an Excel-native engineering calculation tool built by 3D-LABS for chemical, process, and plant engineers working on separation, reaction, heat-transfer, and fluid-flow calculations. It is used for sizing distillation columns, reactors, heat exchangers, pumps, and pressure-relief devices. Every input is labelled and every output is traceable — the sheet is designed to be checkable, not a black box.
Codes and standards followed
Crash Energy Absorption — Front Crumple Zone follows industry-standard Chemical & Process Engineering codes including ASME B31.3, API 520/521 relief sizing, TEMA, HEI, Perry's Chemical Engineers' Handbook methods. Each formula is cross-referenced to the applicable code clause so your reviewer can trace calculations back to the standard.
If your project requires a different code base (e.g. converting an IS-code sheet to an ASME basis), we can produce a code-variant edition on request. Contact info@3d-labs.com for a variant quote.
What is included in your download
- The Excel calculation file (.xlsx) — fully unlocked formulas, cell-level comments, and a clear input/output layout.
- A sample worked example — realistic inputs plus expected outputs so you can validate the spreadsheet against a known case.
- User notes (PDF) — assumptions, code clauses referenced, and edge-case guidance.
- Revision history — every update to the spreadsheet is logged so you know what changed and when.
- Email support — reply within 24 hours (Monday to Saturday, IST) for questions about the spreadsheet or its use.
