Line pipe is a seamless steel pipe designed for transporting gas, water, and other fluids in the petroleum and natural gas industry. It meets API 5L standards, ensuring reliability for high-pressure applications such as oil and gas transmission. The pipe is available in a range of outer diameters and wall thicknesses to suit various operational demands.
Sourced from a Chinese manufacturer, this line pipe is produced with precision to meet industry requirements for durability and performance. It is suitable for both onshore and offshore projects, including subsea pipelines, where seamless construction minimizes leak risks and corrosion resistance is critical. Bundles are neatly packed for bulk handling and logistics efficiency.
Purchasing line pipe for industrial use requires attention to material grade, diameter, and wall thickness to align with project specifications. Always verify compliance with API 5L and confirm test reports from the supplier to ensure traceability and quality assurance. Integration into existing pipeline systems demands proper welding procedures and pressure testing as per industry standards.

Best Fit & Nearest Alternatives
Best suited for:
- Oil and gas transmission pipelines
- Subsea and onshore pipeline projects
- High-pressure fluid transport systems
- Industrial water conveyance lines
Not ideal for:
- Low-pressure or low-flow applications
- Temporary or short-term installations
Grade B line pipe offers cost efficiency for standard applications, while higher-grade pipes (e.g., X42 or X52) provide enhanced strength for extreme conditions or corrosive environments.
What Drives the Price
- Outer diameter and wall thickness (heavier walls cost more per meter)
- Grade of steel (higher grades command premium pricing)
- Quantity ordered (bulk discounts apply above certain thresholds)
- Surface finish and coating requirements (e.g., anti-corrosion treatments)
Pricing scales with order volume and minimum order quantity (MOQ). Request a detailed quote from the supplier based on your specific requirements and project scale.
Lead Time, Shipping & Returns
- Lead time: Typical production lead time is 15 - 30 days after order confirmation; confirm with supplier for exact timelines based on current capacity.
- Shipping: Standard modes include containerized ocean freight for bulk orders or flat-rack shipping for oversized bundles. Air freight is not typical due to cost and dimensional constraints.
- Returns & defects: Defective or non-conforming material can be returned subject to inspection and supplier approval. Inspect goods upon arrival for visual defects, documentation accuracy, and compliance with specifications. Report discrepancies within 7 - 14 days of delivery.
Handling & Application Notes
- Store in a dry, covered environment to prevent moisture-induced corrosion before installation.
- Use certified welding procedures and filler metals compatible with the pipe grade during assembly.
- Pressure test all joints and sections to 1.5x operating pressure before commissioning.

Frequently Asked Questions (FAQs) on Line pipe
1. What API 5L grade options are available for this line pipe?
Common grades include A, B, X42, X52, and higher. Confirm the exact grade and chemical composition with the supplier to match your project standards.
2. Can the pipe be supplied with internal coating for corrosion protection?
Yes, internal coatings such as epoxy or FBE can be applied upon request. Discuss specifications and compliance with the supplier during order placement.
3. Is the pipe suitable for sour service environments?
Sour service suitability depends on the steel grade and heat treatment. Specify sour service requirements (e.g., NACE MR0175) when ordering to ensure material selection aligns with environmental conditions.
4. What documentation accompanies each shipment?
Typical documents include mill test certificates (MTC), material traceability reports, and packaging lists. Request a full document list from the supplier prior to shipment.
5. How are bundles packaged for export shipment?
Bundles are typically secured with steel straps and wrapped in protective material. Some suppliers use wooden crates or steel frames for long-distance transport; confirm packaging method with the supplier.
6. Does the supplier provide on-site inspection services?
Yes, third-party inspection services can often be arranged at the manufacturing facility or loading port. Confirm availability and cost with the supplier in advance.
7. What is the typical tolerance for diameter and wall thickness?
Dimensional tolerances generally follow API 5L standards (±0.5% for OD and ±10% for WT). Ask the supplier for a detailed dimensional tolerance report.
8. Is the supplier capable of producing custom lengths beyond 10 meters?
Standard maximum length is 10 meters, but custom lengths may be available upon request. Confirm feasibility and additional costs with the supplier.
