Heavy-Duty LSAW, SSAW & Anti-Corrosion Steel Pipes

Your Premier Steel Pipe Manufacturer

Hebei Allland Steel Pipe Manufacturing Co., Ltd. is dedicated to producing high-performance steel pipes for the world’s most demanding industrial sectors. Located in Zhifangtou Industrial Park, Cangzhou, we manage the entire production and coating process to ensure exceptional durability. Whether you require robust onshore pipelines for oil and gas or high-strength piling pipes for marine infrastructure, we deliver certified piping solutions tailored to your project specifications.

Our Core Steel Pipe Inventory

We manufacture 14 distinct categories of steel pipes to meet diverse engineering challenges:

• Welded Steel Pipes: High-capacity LSAW (Longitudinal Submerged Arc Welded) and SSAW (Spiral Submerged Arc Welded) pipes for heavy industry and fluid transmission.

• Anti-Corrosion Coated Pipes: Advanced external coatings including 3LPE, 3LPP, and FBE to maximize pipeline lifespan, alongside specialized safe drink water pipelines.

• Application-Specific Pipes: Including offshore and onshore pipelines, structural pipes, piling pipes, high-pressure pipes, floating pipes, shoulder pipes, and sprinkler steel pipes.

Strict Adherence to International Standards

To ensure safety and reliability in critical infrastructure, our steel pipes are manufactured and tested to strict global standards. Our products fully comply with API 5L, ASTM (A53, A252, A500, A671, A672), EN (10219, 10255, 10217), ISO (3183, 21809), DIN, JIS, and AS/NZS 1579 requirements.

Frequently Asked Questions (FAQ)

Q: What is the difference between your LSAW and SSAW steel pipes?
A: LSAW pipes are manufactured using a single longitudinal weld, making them ideal for high-pressure onshore and offshore pipelines. SSAW pipes feature a spiral weld, allowing for the production of very large diameter pipes, typically used for water transport, structural piling, and lower-pressure applications.

Q: What types of anti-corrosion coatings do you apply to the pipes?
A: We provide state-of-the-art anti-corrosion treatments, primarily focusing on Fusion Bonded Epoxy (FBE), 3-Layer Polyethylene (3LPE), and 3-Layer Polypropylene (3LPP). These protect your offshore and underground pipelines from harsh environmental degradation.

Q: Can you manufacture steel pipes for specialized applications like floating or piling?
A: Yes. Beyond standard fluid transmission, we engineer customized piling pipes for deep foundation construction, floating pipes for dredging operations, and structural pipes for large-scale architectural and heavy industrial projects.
