📌 Overview
The Pipeline Pigging Calculator is a powerful engineering tool designed to estimate pig travel speed, travel time, and operational recommendations based on pipeline operating conditions. This calculator supports multiphase flow (gas + liquid) and accounts for real-world conditions such as compressibility and pipeline dimensions.
🧾 Input Parameters
- Pipeline Length – Accepts input in meters, kilometers, miles, or feet
- Pipeline Diameter – Supports input in inches or millimeters
- Gas Flowrate – Accepts standard flow units such as MMSCFD, SCFH, or Sm³/h
- Liquid Flowrate – Accepts BPD, GPM, or m³/h
- Inlet and Outlet Pressure – Supports psi, bar, or Pa
- Gas Compressibility Factor (Z)
- Distance to Target – Location where pig arrival is tracked (in km or miles)
🧮 Calculations Performed
- Cross-sectional Area of pipeline
- Actual Gas Flow Adjustment using compressibility factor and pressure correction
- Velocity of Gas and Liquid in the pipeline (combined flow)
- Total Pig Velocity
- Travel Time to Target (in minutes)
- Smart Pigging Recommendation based on speed range
📤 Output Results
- 🌀 Pig Velocity (m/s)
- 🕒 Estimated Travel Time (minutes)
- ✅ Recommended Pig Type (foam pig, bypass pig, etc.)
🔍 Use Cases
- Pre-run pigging feasibility checks
- Cleaning schedule planning
- Tracking and monitoring pig position
- Optimizing flow conditions for pig movement
