Single-Layer Anti-Corrosion Epoxy Powder Pipes are steel pipes coated with a fusion-bonded epoxy (FBE) layer, providing excellent resistance to corrosion in harsh environments. Compliant with standards like DIN 30670, ASTM A53, and AWWA C213, these pipes are ideal for oil and gas pipelines, water supply systems, and chemical processing plants, offering a minimum tensile strength of 415 MPa and an FBE coating thickness of 300-500 microns.

The FBE coating is applied through electrostatic spraying onto a preheated steel surface (~200-240°C), forming a hard, uniform layer with strong adhesion. Available in sizes from 20 mm to 1220 mm outer diameter, with wall thicknesses from 1 mm to 80 mm, and lengths in random, fixed, SRL, or DRL configurations, these FBE Coated Pipes meet diverse project needs. The coating process includes shot blasting and intermediate frequency preheating to ensure durability. Ends can be plain, beveled, or threaded, with protective caps or rings for installation ease.

Rigorous testing, including tensile, hydrostatic, and coating adhesion tests, ensures compliance with industry standards. The FBE layer provides superior resistance to chemicals like acids, alkalis, and salts, making Corrosion-Resistant Steel Pipes suitable for fire protection systems and wastewater treatment plants. The coating’s high mechanical strength and flexibility withstand bending and impact, ideal for HVAC systems.

Compared to multi-layer coatings like 3LPE or double-layer FBE, Single-Layer Anti-Corrosion Epoxy Powder Pipes are more cost-effective for applications with moderate corrosion risks, offering a lifespan of 20-30 years. They require periodic inspection in extreme conditions but provide reliable performance in most soil and fluid environments.

Single-Layer Anti-Corrosion Epoxy Powder Pipes address pipeline corrosion, chemical degradation, and mechanical wear, delivering durable, cost-efficient solutions for industrial piping systems.
