API 5L Grade X52
Yield Strength: ≥ 360 MPa
Tensile Strength: ≥ 460 MPa
Chemical Composition (Typical for X52 PSL1)
Carbon (C): ≤ 0.28%
Manganese (Mn): ≤ 1.40%
Phosphorus (P): ≤ 0.030%
Sulfur (S): ≤ 0.030%
Note: PSL2 requirements may include stricter limits on carbon equivalent (CE) and additional alloying elements for improved toughness.
Mill Test Certificates (MTC) provided in accordance with EN 10204/3.1
Manufacturing: LSAW
The Longitudinal Submerged Arc Welding (LSAW) process involves forming steel plates into cylindrical shapes and welding the longitudinal seam using submerged arc welding technology. This method ensures:
Superior weld quality and consistency.
High dimensional accuracy in outer diameter and wall thickness.
Enhanced structural strength suitable for high-pressure environments.
Advantages
High Strength-to-Weight Ratio: Grade X52 offers an optimal balance between strength and ductility, allowing for thinner wall designs without compromising safety, which reduces material and transportation costs.
Excellent Weldability: The low carbon equivalent of X52 steel ensures excellent weldability, facilitating efficient field jointing and reducing construction time.
Reliability in Extreme Conditions: Suitable for operation in diverse climates, including cold regions, due to its good low-temperature impact toughness (especially in PSL2 grade)
Surface Treatment & Coating
To ensure longevity and protect against environmental corrosion, the pipes can be supplied with various surface treatments:
Black Varnish/Oil: For temporary protection during storage and transport.
3LPE (Three-Layer Polyethylene): Standard for buried pipelines, offering superior mechanical and chemical resistance.
FBE (Fusion Bonded Epoxy): Provides excellent adhesion and corrosion protection.
Internal Coating: FBE or epoxy coating for improved flow efficiency and internal corrosion resistance.
Applications
API 5L X52 LSAW steel pipes are widely used in:
Oil and Gas Transmission: Mainline pipelines for crude oil, refined products, and natural gas.
Water Transport: Large-diameter municipal water supply and sewage treatment pipelines.
Offshore Engineering: Subsea pipelines and structural piles for offshore platforms.
Industrial Piping: Process pipelines in chemical, power, and mining industries.
