JIS G3469 P2S Polyethylene Coated Steel Pipe For Anti Corrosion Service
JIS G3469 P2S P1H P1F Polyethylene Coated Steel Pipe for Anti-corrosion Service
Material
JIS G3469 specifies polyethylene coated steel pipes designed for anti-corrosion applications, primarily used in transporting water, gas, and other fluids where corrosion resistance is critical. The pipes are manufactured from carbon steel, and the polyethylene coating provides excellent protection against environmental corrosion.
The grades P2S, P1H, and P1F represent different steel materials and manufacturing conditions under the JIS G3469 standard with varying mechanical properties suited for specific service requirements.

Key Features
- Corrosion resistance: Polyethylene coating provides excellent protection against moisture, soil, and other corrosive environments.
- Durability: The steel pipe offers mechanical strength combined with anti-corrosion properties.
- Versatility: Suitable for both underground and above-ground applications.
- Ease of Handling: Coated pipes are lighter and easier to handle due to their smooth surface.
- Compliance: Meets stringent Japanese Industrial Standards ensuring high quality and reliability.
Application
- Water distribution pipelines
- Gas transportation pipelines
- Chemical plants and refineries
- Sewage and wastewater facilities
- Anti-corrosion systems in industrial plants
- Infrastructure projects requiring durable corrosion-resistant piping
Equivalent Grades
| JIS G3469 Grade | Equivalent Standards / Materials |
|---|---|
| P2S | ASTM A53 Grade B, API 5L Grade B |
| P1H | JIS G3469 Higher strength steel grade |
| P1F | JIS G3469 High-strength, tempered steel pipe |
Equivalent grades vary depending on the mechanical and chemical requirements but generally correspond to commonly used carbon steel pipes with corrosion protection in international standards.
