Technical Tools Hub
Two engineering calculators used in Raphoon's own project work — available at no cost, no login required.
These are not estimating tools. The Composite Repair calculator follows the ASME PCC-2 Article 401 / ISO 24817 strain method using fixed RRL/Raphoon material constants. The HDD Risk calculator scores three independent risk components — pipe size and weight, HDD design geometry, and soil abrasivity — and returns a system selection recommendation. Results should be reviewed by a qualified engineer before any repair or system change.
Enter your pipe geometry, defect dimensions, design pressure, and steel grade. The calculator returns required repair thickness, layer count, and total axial repair length — sized per ASME PCC-2 using RRL carbon fiber and polyurethane material constants. Use this when your ILI report shows wall thinning that requires an engineered repair.
Enter your pipe OD and wall thickness, bore length and diameter, minimum bend radius, and soil types by segment length. The calculator scores size/weight risk, design risk, and soil abrasivity risk independently, then sums them into a total risk index and recommends a coating protection level. Use this before selecting a coating system for any directional drill section.
Upload an HDD plan/profile drawing and core sample logs. The analyzer reads the pipe configuration table, drill geometry, and soil layers, then pre-fills the HDD Coating Risk calculator below.

Composite Repair result needs field review?
A layer count and total length are a starting point. Field application quality, surface preparation, and correct material handling determine whether the repair actually holds. We evaluate and inspect composite repairs against the calculated values.
HDD risk score prompting a system change?
A high risk score means your current coating system selection may not survive the pull — or the long-term abrasion in the bore hole. We consult on coating selection specifically for directional drill sections.
