Pig Launcher Design ASME B31.4 Calculation
Comprehensive Engineering Workbook — Instant Download
What This Workbook Does
Designs the complete pig launcher and receiver assembly for liquid hydrocarbon pipelines per ASME B31.4. Covers every component of a pigging facility — barrel, reducer, end closure, kicker line, equalizer line, support saddles, and instrumentation tappings — in one auditable workbook.
What’s Inside the Workbook
- Major barrel sizing per pig OD and overlength requirements
- Minor barrel matched to pipeline OD
- Eccentric reducer connecting major to minor barrel
- Quick-opening end closure sizing per design pressure
- Pipe wall thickness for barrel components per ASME B31.4
- Kicker line sizing for pig launch velocity
- Equalizer line and vent/drain sizing
- Support saddle reactions for civil foundation design
- Weight and CG for transport and installation
- Datasheet output in standard pigging facility format
Who This Workbook Is For
- Pipeline design engineers in Oil & Gas
- EPC pipeline teams on midstream and crude transport projects
- Pigging facility designers and fabricators
- Pipeline operators specifying new launcher/receiver installations
- Engineering consultancies billing pigging facility design
Codes & Standards Referenced
- ASME B31.4 — Pipeline Transportation Systems for Liquids and Slurries
- ASME VIII Division 1 — for end closures designed as pressure vessels
- API 1130 — pipeline pigging operations (referenced for sizing)

Why This Workbook Is Worth ₹16,099
A complete pig launcher facility design normally takes a senior pipeline engineer 2–3 days of calculation work, drawing back across barrel sizing, end closure pressure rating, support reactions, and ancillary line sizing — all separate sheets to maintain. This workbook consolidates it into one auditable Excel file with cross-references between components. For an EPC pipeline office, the time saving covers the cost on the first facility design.
Frequently Asked Questions
B31.4 only or B31.8 (gas) too?
This workbook is optimised for B31.4 liquid pipelines. Gas pipeline (B31.8) version available on request as a custom adaptation.
End closure design?
The workbook handles standard quick-opening closure sizing. For proprietary brand closures (T.D. Williamson, GD Engineering), use the manufacturer’s load data with the workbook’s interfacing calculations.
Do you offer full pipeline design service?
Yes — see our Piping Design and Piping Stress Analysis services for full pipeline engineering.
Custom version (B31.8 gas)?

Need Full Pipeline Design Service?
If you need complete pipeline design with stress analysis, line lists, and drawings rather than a calculation workbook, 3D-LABS delivers full piping engineering services. Learn more about Piping Design or request a quote.
