Handling Coated Pipes and Coating Materials
Translate this article:

Coating materials
- Store enamels and primers away from heat
- Keep solvents closed
Coated pipes
- Use padded slings
- Avoid stacking too high
- Protect from prolonged UV exposure
Harder, gilsonite-modified coatings resist handling damage better.

Coating materials
| Material | Storage rule |
|---|---|
| Hot enamel blocks | Dry, covered, away from heat |
| Primers | Closed containers, ventilated area |
| Tapes | Cool, out of direct sun |
Coated pipes
- Use padded supports and nylon slings, not chains or hooks.
- Separate layers with timber or sand berms.
- Do not drag pipes on the ground.
- Protect from long UV exposure in hot climates.
Repair before laying
Inspect and holiday test pipes before lowering into the trench, and repair any damage with compatible materials.
