Specification

Coatings & Protection

To resist corrosion (critical for buried or marine environments), API 5L Grade B spiral pipes often use:

3LPE (3-Layer Polyethylene): A common coating for soil or water immersion, combining epoxy primer, adhesive, and polyethylene top layer.

FBE (Fusion-Bonded Epoxy): A durable, thin coating for high-temperature or abrasive conditions.

Galvanization: For above-ground, non-critical applications (e.g., temporary pipelines).

Nominal Diameter (DN): 

Ranges from DN10 (10.2 mm OD) to DN600 (610 mm OD), with DN15-DN300 common for structural use.

Wall Thickness (WT): 

For hot-finished pipes, WT ranges 2.3 mm-40 mm with ±12.5% tolerance; cold-finished pipes have WT 1.5 mm-12 mm with ±10% tolerance.

Straightness:

≤1 mm/m for cold-finished pipes, ensuring easy installation in structural frameworks.

End Finish:

Plain ends (standard) or beveled ends (for welding), with squareness tolerance ≤1% of OD.

Applications

Oil & Gas Industry: Transmission pipelines for crude oil, natural gas, and refined products.

Water Infrastructure: Municipal water supply, wastewater treatment, and irrigation systems.

Industrial Pipelines: Transportation of chemicals, slurry, or steam in power plants and refineries.

Construction: Structural supports in bridges, piers, or offshore platforms (when coated for durability).

Manufacturing Process:

Governs line pipe for oil, gas, and water transportation, including both seamless and welded (e.g., spiral, ERW) varieties.

Performance Advantages:

Dual Utility: Suitable for both pressure applications (water, steam, gas conveyance) and structural uses (frames, supports).
Cost-Effective: Carbon steel composition balances performance and affordability, ideal for bulk industrial use.
Versatility in Grades: Grade B provides higher strength for demanding pressure systems, while Grade A suits general-purpose needs.
Corrosion Resistance: Galvanized variants offer enhanced protection against rust in humid or outdoor environments.

Compliance & Certifications

Must meet API 5L dimensional, chemical, and mechanical standards.

Often certified to ISO 9001 (quality management) and ISO 14001 (environmental management).

For high-pressure or hazardous service, additional certifications (e.g., CE marking for EU markets) may be required.
