API 5L X60 PSL2 Spiral Welded Line Pipes
X60 spiral-welded line pipe is a high-strength, low-alloy steel pipe; the "X60" designation in its name signifies a minimum yield strength of 60,000 pounds per square inch (approximately 414 MPa). Typically manufactured from carbon-manganese steel or micro-alloyed steel, this type of pipe achieves enhanced strength and toughness through the addition of small quantities of alloying elements-such as niobium, vanadium, and titanium-while simultaneously maintaining excellent weldability and corrosion resistance.

Coating and Protection of API 5L X60 PSL2 pipeline
3LPE Coating (Three-Layer Polyethylene): The gold standard for buried X60 pipelines, providing 30+ years of corrosion resistance.
FBE Coating (Fusion Bonded Epoxy): Ideal for internal lining to reduce friction in gas lines or as a primer for external protection.
Anti-UV Protection: Essential for pipes that may sit in coastal storage for extended periods before installation.
