Product Name: Coated Steel Pipes
Introduction
Coated Steel Pipes combine the structural strength of carbon or alloy steel substrates with protective external and/or internal coatings to guard against corrosion, abrasion, and chemical attack. By applying fusion‑bonded epoxy (FBE), three‑layer polyethylene (3LPE), polyurethane (PUR), or cement mortar linings, these pipes extend service life in harsh environments-making them ideal for oil & gas transmission, water distribution, industrial process piping, and underground or subsea installations.

Features & Advantages
Superior Corrosion Protection: Multi‑layer coatings shield steel from soil, sea, and chemical corrosion.
Abrasion & Impact Resistance: Cement mortar and PUR linings withstand slurry and sediment wear.
Long Service Life: Properly coated pipes can exceed 30 years in buried or submerged conditions.
Field Repairability: Damaged coatings can be reinstated on‑site with repair kits matching factory materials.
Compliance Ready: Coating systems and application methods meet AWWA, NACE, ISO 21809, and API 5L standards.
Applications
Oil & Gas Transmission: Onshore and offshore flowlines, gathering mains, and riser systems.
Water & Wastewater: Potable water mains, sewer force mains, and desalination intake lines.
Industrial Process: Chemical plant piping, power‑plant cooling water circuits, and slurry transport.
District Heating & Cooling: Pre‑insulated district energy distribution networks.
Marine & Subsea: Jacket and pile protection, subsea pipelines, and structural pilings.
Packaging & Delivery
Bundling: Pipes bundled by size and coating type; strapped with corrosion‑resistant bands; timber or polymer spacers.
End Protection: Steel or plastic end caps; temporary weld bead removal and cap sealing to prevent coating damage.
Surface Protection: Outer shrink‑wrap or protective film to guard against transit abrasion.
Lead Time: Typical turnaround of 30–45 days after order; expedited schedules (20–25 days) available for urgent projects.
