Pipeline HDD

About Pipeline HDD

PipelineHDD is the essential field and office tool for Horizontal Directional Drilling (HDD) engineers, pipeline designers, and utility contractors. Quickly calculate critical bending angles, visualize your bore profile with an interactive graph, and generate professional PDF reports — all from your phone or tablet.

*Why PipelineHDD?**

When installing steel or polyethylene (PE) pipelines via HDD, exceeding the allowable bending radius can cause pipe buckling, coating damage, or premature failure. PipelineHDD eliminates guesswork by computing precise critical bending angles based on industry-standard formulas, so you can design safe, compliant bore paths every time.

**Key Features:**

• Dual Material Support — Steel (X42–X80 grades, 4 location classes) and PE (SDR 11, 17, 26+), each with dedicated calculation formulas and material libraries.
• Critical Angle Calculation — Steel uses elastic modulus, yield strength, and design factor; PE uses SDR-based multiplier tables per industry practice.
• Interactive Bore Profile Graph — See your entire drill path rendered in real-time with ground surface elevation, pipe profile, and highlighted error points where bends exceed allowable limits.
• Flexible Angle Input — Enter segment angles in degrees or as slope percentages (%). A single toggle switches between modes, and all calculations update instantly.
• Smart Error Detection — Segments where the angular change exceeds the critical threshold are automatically flagged with red markers on the graph and highlighted in the data table.
• PDF Report Generation — Produce a polished, print-ready A4 report containing project parameters, a bore profile chart, segment data table, error summary, and key statistics. Preview on-screen or save to your device.
• Material Design 3 UI — Clean, modern interface with light/dark theme support, responsive layouts that adapt to phone, tablet, and desktop screens, and intuitive segment management (add, remove, edit).
• Real-Time Recalculation — Every parameter change triggers an instant recalculation of critical angles and the full bore profile. No "Calculate" button needed.

**Who Is It For?**

• HDD drilling crews and field supervisors verifying bore plans on-site
• Pipeline design engineers performing feasibility checks
• Utility contractors preparing submittals and as-built documentation
• Students and educators learning directional drilling mechanics

**Technical Specifications:**

• Minimum bending radius: 0.05 m safety floor
• Steel formula: R = (3 × E × D) / (4 × S × F)
• PE formula: R = Multiplier × 2.5 × D (incorporating a 2.5× safety factor)
• Supported pipe diameters: 50–1219 mm (2–48 inches)
• PDF reports include project header, parameter summary table, rendered bore profile, segment-by-segment data grid, error list with coordinates, and summary statistics

Whether you're in the field verifying a bore plan or in the office preparing engineering documentation, PipelineHDD gives you the numbers you can trust — fast.
