Material & Grade
Standard: API 5L (Latest Edition, typically 46th Edition or as specified)
Grade: X46 (Equivalent to L320 in ISO 3183 metric designation)
Manufacturing Process: Seamless (Hot Rolled or Cold Drawn)
Product Specification Level (PSL): Available in PSL 1 and PSL 2
PSL 1: Standard requirements for general pipeline applications.
PSL 2: More stringent requirements including additional chemical composition controls, toughness testing, and non-destructive testing, suitable for harsher environments.
------------------------------------------------------
Mechanical Properties
Minimum Yield Strength: 317 MPa (46,000 psi)
Tensile Strength: 434 – 555 MPa (63,000 – 80,000 psi)
------------------------------------------------------
Chemical Composition:
Controlled levels of Carbon, Manganese, Phosphorus, Sulfur, and other alloying elements to ensure weldability and toughness. For PSL 2, stricter limits on Carbon Equivalent (CE) are applied to prevent cracking during welding.
Hot rolled manufacturing
Raw Material Selection: High-quality steel billets are selected based on strict chemical composition standards.
Heating & Piercing: Billets are heated to a plastic state and pierced to form a hollow shell.
Rolling & Elongation: The shell is elongated and rolled over a mandrel to achieve the desired diameter and wall thickness.
Sizing & Straightening: Precision sizing ensures dimensional accuracy, followed by straightening to meet tolerance standards.
Heat Treatment: Optional normalizing or quenching and tempering may be applied to enhance mechanical properties, especially for PSL 2 grades.
Inspection & Testing: Each pipe undergoes rigorous testing, including hydrostatic testing, non-destructive testing (NDT), dimensional checks, and mechanical property verification.
quality control
* Hydrostatic Pressure Testing
* Non-Destructive Testing (Eddy Current, Ultrasonic)
* Mechanical Property Testing
* Chemical composition test
* Dimension & Visual Inspection
* Full Traceability (Mill Test Certificates 3.1 provided)
Features & Advantages
High Integrity: The seamless structure provides uniform strength around the circumference, offering better pressure containment than welded pipes.
Corrosion Resistance: Can be supplied with various surface treatments, including black varnish, galvanization, or specialized anti-corrosion coatings (e.g., 3LPE, FBE) upon request.
Weldability: Excellent weldability due to controlled carbon equivalent values, facilitating easy installation and jointing.
Global Compliance: Meets international standards, ensuring compatibility with global engineering projects and regulatory requirements.
.
Application
Oil & Gas Transmission: Mainline pipelines for transporting crude oil and natural gas.
Water Distribution: High-pressure water supply systems.
Industrial Processing: Fluid transport in chemical and petrochemical plants.
Structural Applications: Occasionally used in structural supports where high strength-to-weight ratio is required.
Packaging & Delivery
Packaging: Pipes are bundled with steel strips, with plastic caps on both ends to prevent damage during transit.
Marking: Each pipe is clearly marked with API 5L specification, grade (X46), size, heat number, and PSL level for full traceability.
Delivery: Standard export packaging suitable for sea freight, container loading, or bulk shipment.
