Supplied Helical Pipe Wrap Roll Order calculator.
Convert an already specified helical wrap pitch into continuous tape cut lengths, preserving separate roll fit.
Your inputs
Use measurements from your plan and properties from your chosen product. Any prefilled values are illustrative.

Formula and assumptions
How this calculation works.
Wrap length per run = (run length / supplied pitch) × sqrt((π × supplied wrap diameter)² + pitch²) + supplied tail extra. Does not choose overlap, waterproofing, electrical insulation, corrosion protection or wrap suitability.
A worked example
Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.
- Selected wrap roll length
- 10 m
- Total supplied tail extra per wrapped run
- 0 m
- Supplied wrap centreline diameter
- 0.1 m
- Measured axial run length
- 1 m
- Pitch already specified for the wrap
- 0.05 m
- Identical runs
- 2
Continuous wrap rolls: 2 rolls
Continuous cuts use decreasing-length first-fit packing. This is a feasible count, not a guarantee of the minimum. Any per-cut extra is explicitly reserved by you. Pitch and wrap centreline diameter are supplied, not derived from an installation rule.
Before you purchase
Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.
Does not choose overlap, waterproofing, electrical insulation, corrosion protection or wrap suitability.
