PlexCalc™ by Performance Pipe vs Haverly's PetroCalc

PlexCalc™ by Performance Pipe assists in the design and selection of polyethylene (PE) pipe. PlexCalc™ allows the user to perform a number of PE pipe calculations for Performance Pipe’s DriscoPlex® products including flow rate, pressure capability, reactions to burial and traffic loading, and many others. PlexCalc™ is intended to be used as a supplement to Performance Pipe literature and industry guidelines.

PETROCALC – THE TRUSTED PETROLEUM CALCULATOR IN YOUR POCKET PetroCalc is the all‑in‑one oil & gas calculator that engineers, technicians, and students rely on for fast, accurate viscosity calculations, crude‑oil blending, and every other petroleum‑property task. Whether you need an oil calculator for the field, a crude‑oil calculator for the lab, or a classroom reference, PetroCalc streamlines every petroleum calculation—from viscosity blending to heating‑value look‑ups—completely offline. KEY FEATURES • Unit Conversion – Instantly switch between energy units (MJ/m³, MBTU/bbl, BTU/gal, kCal), temperature (°F/°C), pressure (psi/bar), oil‑density & gravity (kg/m³, API °, specific gravity), kinematic ↔ dynamic viscosity (cSt ↔ cP) and operational scales (SUS, SFS, Redwood I, Engler °), plus calorific‑value conversions and more with our intuitive oil & gas calculator interface. • Distillation‑Curve Tools – Convert temperatures between TBP, ASTM D86, D1160, and D2887 scales and perform yield‑temperature interpolation for full distillation‑curve analysis. • Blending Tools – Execute precise crude‑oil blending and petroleum blending for RVP, Flash Point, Smoke Point, Pour / Cloud / Freeze Point, API Gravity, Aniline Point, Mercaptan Sulfur, Nitrogen, and custom fractions. • Fuel Property Indices – Compute Cetane Index (ASTM D4737 A/B, D976), Driveability Index, Refractive Index, and additional viscosity calculations. • Heating Values – Obtain Gross & Net HHV in MJ/m³, MBTU/bbl, BTU/gal, kCal/kg, and more. • Boiling‑Point Utilities – IBP/EBP plus five average‑boiling‑point methods (Volume, Weight, Molal, Cubic, Mean). • K‑Factor Calculations – UOP K, Watson K, VRC K, Whole‑Crude K at any temperature. • Viscosity Prediction – Single‑point, two‑point (Twu), and API 11A4.2 models with built‑in viscosity‑blending conversions. WHY PETROCALC? • Developed by Haverly Systems, a leader in petroleum‑process modeling. • Optimized for petroleum, chemical, and process engineers—and perfect for students in engineering courses who need a dependable petroleum calculator and oil calculator for coursework. • Works fully offline—no data connection required on‑site. • Simple, accurate, and fast: the only crude‑oil calculator and petroleum‑blending tool you’ll ever need. Download PetroCalc today and tackle every oil & gas calculation—from distillation‑curve conversions and viscosity blending to heating values—with confidence.
