1. Product Definition: Engineered for Critical Pipelines

Safety is non-negotiable when transporting high-pressure gas.
Our API 5L X65 PSL2 LSAW Line Pipe is specifically manufactured for long-distance oil & gas transmission and offshore applications. Unlike standard welded pipes, we use the advanced JCOE (Longitudinal Submerged Arc Welding) process to ensure superior geometric accuracy and weld integrity.
Core Grade: API 5L X65 PSL2 (Yield Strength ≥ 450 Mpa)
Manufacturing Process: JCOE / LSAW
Key Feature:-20°C Impact Test Guaranteed for extreme cold environments.
Primary Use: High-pressure gas transmission, Offshore jacket legs, Slurry pipelines.

2. The JCOE Process Advantage (Why it matters?)

Why do we use the JCOE process instead of traditional rolling? Because it guarantees Perfect Roundness.

J-ing: The steel plate is pressed into a"J"shape.
C-ing: It is further pressed into a"C"shape.
O-ing: Finally formed into an"O"shape.
E-xpanding (Mechanical Expansion): This is the most critical step. We expand the pipe from the inside to eliminate residual stress and ensure the diameter tolerance is within ± 2mm.
Result: A pipe that is perfectly round, making on-site welding much faster and safer.

3. Technical Superiority: Why Choose PSL2 over PSL1?

Many suppliers offer cheap PSL1 pipes, but they are unsafe for high-pressure gas. Here is why you need our PSL2pipes:

Feature	API 5L PSL1 (Standard)	API 5L PSL2 (Our Product)
Application	Low Pressure Water/Oil	High Pressure Gas / Subsea
Impact Test (CVN)	Not Required	Mandatory (-20°C / 0°C)
Fracture Toughness	Low risk tolerance	High resistance to brittle fracture
Chemical Composition	Loose limits	Strict Carbon Equivalent (CE) limits
Weldability	Standard	Excellent (Easy for field welding)

4. One-Stop Anti-Corrosion Solutions

LSAW pipes are valuable assets. We don't ship them naked. We provide integrated coating services in our factory:

3LPE (3-Layer Polyethylene): The standard for buried pipelines. Service temp -40°C to 80°C.
FBE (Fusion Bonded Epoxy): Excellent adhesion and chemical resistance.
Concrete Weight Coating (CWC): For subsea pipelines to provide negative buoyancy (keep the pipe on the ocean floor).

5. Strict Quality Control (QC)

We welcome Third Party Inspection (TPI) from SGS, BV, or DNV. Our internal QC includes:

100% Ultrasonic Testing (UT): Checks the weld seam and the full pipe body.
100% X-Ray (RT): Digital radiography for weld seams.
Hydrostatic Testing: Each pipe is tested at 100% specified pressure for 10 seconds.

2. Technical Superiority: PSL1 vs. PSL2

We specialize in API 5L PSL2 (Product Specification Level 2), which is mandatory for high-risk, high-pressure, and offshore environments where material failure is not an option.

Feature	API 5L PSL1 (Standard)	API 5L PSL2 (Our Premium Range)	Why it Matters
Impact Test	Not Required	Mandatory (CVN at -20℃ or 0℃)	Prevents brittle fracture in low-temperature or high-stress environments.
Chemistry (CEq)	No Strict Limit	Strict Pcm ≤ 0.25 or CE ≤ 0.43	Guarantees excellent field weldability and minimizes heat-affected zone (HAZ) cracking.
Yield/Tensile Ratio	Not Specified	Maximum ≤ 0.93	Ensures the pipe has sufficient ductility to withstand soil movement or seismic activity.
Inspection (NDT)	Basic/Sampling	100% UT (Ultrasonic) + RT (Radiographic)	100% verification of the longitudinal weld seam for zero internal defects.
Hydrostatic Test	Standard Pressure	Higher Test Pressure & Duration	Ensures 100% leak-proof performance under maximum operating pressures.

4. Quality Assurance & Testing Protocols

To guarantee the longevity of your project, every pipe undergoes rigorous testing:

Mechanical Tests: Tensile, Flattening, Guided-bend, and Charpy V-Notch Impact tests.
100% Non-Destructive Testing (NDT): Including Automatic Ultrasonic Testing (AUT) of the weld seam and X-Ray inspection of pipe ends.
Surface Inspection: 100% visual and dimensional check for laminations or surface imperfections.
Certification: Full MTC (Mill Test Certificate) issued according to EN 10204 3.1 or 3.2 (Lloyd's, BV, or SGS witness).

Ensuring the structural integrity and surface quality of our LSAW pipes during long-distance international transit is our top priority. We implement a multi-layered protection strategy:

1. Precision End Protection & Preparation

Standard Beveling: Pipes are precision-beveled to a 30° (+5°/-0°) angle with a 1.6mm (±0.8mm) root face, ready for immediate on-site welding.
Heavy-Duty Protectors: Unlike standard plastic caps, we use Heavy-Duty Recessed Metal Protectors or Steel-Reinforced Plastic Caps. These are designed to withstand high-impact collisions during crane loading, ensuring the welding face remains defect-free.
Rust Prevention: Beveled ends are treated with a clear, weldable anti-corrosion wax to prevent flash rusting without requiring cleaning before welding.

2. Advanced Surface Protection Options

We offer customized coating solutions based on your project’s storage duration and environmental exposure:

Option A: Temporary Protection (Black Varnish): A high-quality, quick-drying bituminous coating that provides effective rust resistance during sea transit and short-term site storage.
Option B: Long-Term Anti-Corrosion (3LPE / 3LPP / FBE): For burial or offshore use, we provide multi-layer Polyethylene/Polypropylene coating. We include padded strapping and extra-thick separators to ensure the coating remains scratch-free during handling.
Internal Lining: Optional Liquid Epoxy Lining to maintain internal smoothness and prevent internal corrosion from moisture.

3. Professional Loading & Logistics Safety

Our logistics team follows a strict "Zero-Damage" protocol for container and bulk vessel loading:

Spreader Beam Lifting: We exclusively use specialized non-marking spreader beams and nylon slings. This prevents "point-loading" stress, which can cause bending or ovality in heavy-wall LSAW pipes.
Strategic Securing (Dunnage & Bracing): * In-Container: Pipes are secured using customized wooden dunnage, chocks, and heavy-duty steel strapping to prevent shifting during rough sea conditions.
- Bulk Vessel: We implement "tier-nesting" with rubber or timber separators between layers to eliminate metal-to-metal contact.
Custom Length Optimization: Our 11.8m - 12.2m fixed lengths are specifically designed to maximize the space of 40ft High Cube containers, reducing shipping costs for our clients while ensuring a secure fit.
