3PE vs Epoxy vs Plastic Coating: How to Choose for Indonesian Soil
The 5-Minute Coating Decision
Choosing anti-corrosion coating comes down to three site factors: soil corrosivity, operating temperature and media. For buried water and gas lines in coastal Indonesia, 3PE is almost always the answer; for hot oil service pick epoxy; for potable water lines, plastic coating.
Quick Comparison
- 3PE — buried pipelines, 30+ year life, GB/T 23257
- Epoxy (FBE) — oil & gas, high temperature, SY/T 0315
- Plastic — potable water & sewage, CJ/T 120
