L415 pipeline pipe is a high-grade steel pipeline pipe for oil and gas transportation, conforming to GB/T9711-2017 and API 5L standards.
Core technical parameters are reflected in its mechanical properties and dimensional specifications:
Mechanical Properties:
Yield Strength: 415-565MPa
Tensile Strength: ≥520MPa
Elongation after Fracture: ≥18%
Impact Test Temperature: 0℃, -20℃, etc., depending on the grade
Impact Energy: ≥34J
Hardness: Brinell Hardness ≤250HB

Chemical Composition:
Carbon Content: ≤0.26%
Manganese Content: 1.20-1.80%
Silicon Content: ≤0.45%
Phosphorus Content: ≤0.025%
Sulfur Content: ≤0.025%
Microalloying elements such as niobium, vanadium, and titanium are often added, and controlled rolling and cooling processes are used to improve overall performance.
Size Specifications: Outer diameter typically ranges from 21.3 to 1422 mm; wall thickness ranges from 2.0 to 40.0 mm; length typically ranges from 6 to 12 m. We can produce standard length, custom length, and multiple length tubes.
L415 pipeline pipes are widely used in multiple industries, primarily including:
- Oil and natural gas transportation: Used in long-distance pipeline systems to transport crude oil, natural gas, and other media.
- Urban gas pipeline networks: Serving as the main pipeline material for urban gas transportation, ensuring the safety of gas supply for residents and industries.
- Chemical industry: Used to transport various chemical media, such as liquefied petroleum gas (LPG) and ammonia.
- Water conservancy projects: Some water conservancy facilities also use this type of steel pipe for water transport or structural support.
