Lsaw Steel Pipe Astm A572
This LSAW steel pipe is manufactured to ASTM A572 Grade 50, a high-strength low-alloy structural specification using columbium-vanadium alloyed carbon steel. The longitudinal submerged arc welding process ensures strong weld integrity, while the pipe’s large diameter range of 16 to 60 inches (406.4 to 1524 mm) suits heavy-duty applications. It complies with ASTM A572 standards and is designed for use in oil and gas pipelines, structural piling, and water transmission systems where durability and mechanical strength are critical.
The material’s HSLA composition delivers a yield strength of 50 ksi (345 MPa typical for Grade 50), making it a preferred choice for structural projects requiring high load-bearing capacity. Typical industry specifications for LSAW pipes include wall thicknesses from 5.0 to 50 mm, with standard lengths of 6 to 12 meters. Surface coatings such as fusion bond epoxy, 3PE, or bitumen are applied as per project requirements to enhance corrosion resistance.
Common buyers include oil and gas developers, construction firms, and infrastructure contractors sourcing pipes for long-distance transmission or piling. The UO, RB, and JCO forming processes ensure precise dimensional control, with typical tolerance ranges of ±0.5% for outer diameter and ±10% for wall thickness. Importers should confirm packaging, which is usually in bulk or bundled, and inspect mill test certificates (EN 10204/3.1B) for chemical and mechanical properties before shipment.

Sourcing Lsaw Steel Pipe Astm A572 from Threeway Steel Co., Ltd. - China Import Guide
Before ordering, verify the pipe’s compliance with the required standards, such as ASTM A572 Grade 50, and confirm the mill test certificate includes all chemical and mechanical properties. Check the surface coating specifications to ensure they match the environmental conditions of your project, as incorrect coatings can lead to premature corrosion.
Confirm logistics details, including packaging (bulk or bundled), loading port in China, and incoterms such as FOB or CFR. Lead times for LSAW pipes can vary significantly based on diameter, wall thickness, and custom specifications, so request a production schedule upfront. Payment terms, typically TT or LC, should also be agreed upon to avoid delays.
Inspect the pipes upon arrival for dimensional accuracy, surface defects, and coating integrity. Use calipers to verify outer diameter and wall thickness against the specified tolerances. For critical applications, consider third-party inspections or additional tests like ultrasonic testing to ensure the pipes meet all performance and safety requirements.
