Switch between 280MPa water jet and mechanical grinding without changing tools. The JT-1-F handles both coating stripping (water jet) and heavy corrosion (grinding) in one pass — work that single-mode robots cannot complete.
Water jetting achieves SA 2.5 on bulk surfaces — but weld seams, nozzle cutouts, pitted areas, and edge zones require a different tool. These discontinuities are where corrosion initiates and where coating adhesion is most critical. Manual grinding of these zones accounts for only 15% of surface area but 40% of total man-hours in a typical tank maintenance project — because every weld meter demands slow, careful, multi-pass grinding by a skilled operator working at height.
The Jingtao Energy JT-1-F is the precision complement to the JT-2’s bulk coverage. Its diamond-grinding end-effector profiles weld seams to the exact surface roughness (Rz 50–75 μm) required for epoxy coating adhesion per ISO 8501-1. Where water jet alone cannot maintain consistent standoff distance — tight-radius nozzle cutouts, pitted areas requiring feathering, edge zones needing a defined anchor profile — The JT-1-F takes over.
| End-Effector | Application | Surface Profile | Coverage Rate |
|---|---|---|---|
| Diamond grinding wheel | Weld seam profiling, coating removal | Rz 50–75 μm | 80–120 m²/day |
| Wire brush (rotary) | Light rust removal, pre-NDT cleaning | St 2–St 3 | 150–200 m²/day |
| Needle scaler | Heavy scale removal, irregular surfaces | Variable | 60–100 m²/day |
In the Singapore Pulau Bukom refinery campaign, the asset owner’s integrity specification required SA 2.5 on 100% of surface area — including welds, nozzles, and edges. A water-jet-only approach would have left these zones at SA 2.0, triggering a coating warranty rejection. The JT-1-F was deployed in tandem with two JT-2 units: JT-2 robots covered bulk shell areas at 300 m²/day while the JT-1-F followed behind, grinding every weld meter and nozzle cutout to specification. The result: 100% SA 2.5 compliance across all 3,200 m², verified by independent third-party coating inspector.
For asset owners considering robotic deployment, this pairing is not optional — it is the difference between passing and failing a coating warranty inspection. Budget for one JT-1-F for every two JT-2 units.
