3PE Anti-Corrosion Steel Pipeis a high-reliability piping solution with a three-layer protective structure—epoxy primer, adhesive, and polyethylene outer layer—integrated with a steel base, tailored for harsh-environment fluid transport. It is extensively applied in oil/gas transmission pipelines (onshore/offshore), municipal water supply networks, and chemical fluid transfer systems, addressing the critical need for long-term corrosion resistance in infrastructure projects.
A key advantage of3PE Anti-Corrosion Steel Pipeis its superior multi-layer protection. The epoxy primer adheres tightly to steel to prevent initial rust, the adhesive bonds primer and polyethylene, and the outer polyethylene blocks moisture, saltwater, and acidic gases (e.g., H₂S). This structure extends service life to over 30 years, far exceeding uncoated or single-layer coated steel pipes, while minimizing leakage risks and maintenance frequency.
3PE Anti-Corrosion Steel Pipefurther combines strength and adaptability. Its steel core ensures high pressure resistance (suitable for 10–120 MPa systems) and impact durability, making it ideal for underground burial or above-ground installation. The lightweight polyethylene layer eases handling, and the pipe complies with standards like API 5L and DIN 30670 for compatibility with welding/mechanical joints. Whether used in cross-country gas lines or industrial chemical pipelines, it delivers stable performance in corrosive conditions.
