1. Product Definition: The Best Value for Deep Foundations

Stop overpaying for LSAW pipes on structural projects.OurSSAW (Spiral Submerged Arc Welding) Steel Pipe Piles are engineered specifically for deep foundation projects where cost-efficiency and high bearing capacity are critical. Manufactured to ASTM A252 Grade 3 standards, they offer the same structural strength as straight-seam pipes but at a 15% - 20% lower cost

*Core Standard: ASTM A252 Grade 3 (Yield Strength ≥ 310 Mpa)

Process: Double-sided Submerged Arc Welding (DSAW) * Primary Use: Wharf Piling, Bridge Foundations, Roadbed Reinforcement

2. Why Choose SSAW over LSAW? (Smart Procurement)

Many engineers ask: "Can I replace LSAW with SSAW?"The answer is YES for structural use. Here is the comparison:

Feature	LSAW (Longitudinal Seam)	SSAW (Spiral Seam) - OUR PRODUCT
Cost	$$$$ (High)	$$ (Economical)
Production Speed	Slow (JCOE Process)	Fast (Continuous Rolling)
Length Limit	Usually max 12m	Up to 50m (No Splicing Needed)
Application	High Pressure Gas/Oil	Piling & Structure
Conclusion	Overkill for piling	Perfect for piling

3. Critical Dimensions in Stock

We understand that project timelines are tight. We maintain raw coil stock for the most common piling sizes:

24 inch (609mm): Common for land-based structural columns.
36 inch (914mm): Standard for highway bridge foundations.
40 inch (1016mm): Heavy-duty size for seaport wharfs.
Wall Thickness: 10mm - 25.4mm (Standard piling thickness: 12mm, 14mm, 16mm).

4. Quality Assurance: Not Just"Cheap"

Although SSAW is cost-effective, we do not compromise on quality. Every pipe pile undergoes strict inspection before leaving our Cangzhou factory:

100% Ultrasonic Testing: To ensure the spiral weld seam is defect-free.
Hydrostatic Testing: (Optional) If required by client specifications.
Mechanical Testing: Tensile and Yield strength tests per heat number.

5. Customized Fabrication Service

We provide"Ready-to-Drive"piles to save your on-site labor costs:

Splicing: We can weld pipes into ultra-long lengths (e.g., 35m) for bulk shipment.

Attachments: Welding of Steel Shoes (Pile Tips),Flanges, or Shear Rings is available upon request.

Coating: 3LPE, FBE, or Epoxy Coal Tar for marine corrosion protection.

Don't let shipping costs eat your profit. For large diameter pipes (OD > 12"), container loading is inefficient. We specialize in Bulk Vessel Chartering to Southeast Asia, Middle East, and South America.

1. Standard & Grade

Standard: ASTM A252 (Standard Specification for Welded and Seamless Steel Pipe Piles).
Grade: Grade 3 (High Strength, Equivalent to S355/Q345B).
Welding Code: Compliant with AWS D1.1 Structural Welding Code (Crucial for splicing).

2. Chemical Composition (ASTM A252 Gr.3) Ensuring excellent weldability for on-site splicing.

Element	Carbon (C)	Manganese (Mn)	Phosphorus (P)	Sulfur (S)
Max %	≤ 0.26%	≤ 1.40%	≤ 0.035%	≤ 0.035%

3. Mechanical Properties (The "Muscle" of Piling)

Property	Requirement (Grade 3)	Our Factory Guarantee
Yield Strength	≥ 310 MPa (45,000 psi)	≥ 345 MPa (50,000 psi)
Tensile Strength	≥ 455 MPa (66,000 psi)	≥ 490 MPa (71,000 psi)
Elongation	Standard	Enhanced Ductility

4. Dimensional Tolerance (Why it fits perfectly)

Outer Diameter: ± 1% (Standard).
Wall Thickness: -12.5% max under tolerance.
Straightness: ≤ 0.2% of length (Critical for pile driving).

Quality You Can Build On. Since piling pipes support the entire structure (Bridges, Wharfs), we take no risks.

ISO 9001:2015 Certified: Full traceability from raw coil to finished pile.
Mill Test Certificate (MTC): Issued strictly per EN 10204 3.1.
Weld Inspection: 100% Ultrasonic Testing (UT) on spiral welds to prevent cracking during driving impact.
Third-Party Witness: We accept inspection by SGS / BV / DNV before loading.
