Ground Pile Pipe

1. Plate/Coil Preparation: 

Cutting, edge preparation, and surface cleaning of high-quality steel plates/coils to meet foundation pipe standards.

2. Forming: 

Precision bending via UOE, JCOE, or spiral forming methods to achieve desired diameter and structural consistency.

3. Welding: 

Primary seam welding using Submerged Arc Welding (SAW) or HFW—ensuring high-strength, defect-free joints critical for load-bearing.

4. Sizing & Straightening: 

Calibration to strict dimensional tolerances for roundness and straightness, enabling smooth driving into diverse soils.

5. Heat Treatment (Optional): 

Normalizing or quenching & tempering to enhance mechanical properties for high-strength and low-temperature applications.

6. Surface Treatment: 

Optional galvanized, painted, or weathering finishes to resist corrosion from soil chemistry and regional climates.

7. Testing & Inspection: 

Hydrostatic testing, ultrasonic testing (UT), radiographic testing (RT), dimensional verification, and Charpy impact tests.

8. Finishing: 

End preparation (pointing, beveling) for easy driving, splicing, and attachment of reinforcement.

Exceptional Load-Bearing Capacity: 

Engineered to withstand heavy axial and lateral loads, ideal for high-rises, bridges, and industrial facilities.

Climate & Corrosion Resistance: 

Weathering steel (ASTM A588) and coated options resist coastal saltwater, tropical humidity, desert erosion, and acidic soils.

Dimensional Stability: 

Precise geometry ensures consistent driving performance and minimal soil displacement during installation.

Fabrication Flexibility: 

Superior weldability enables splicing, end modification, and reinforcement—adapting to custom project needs.

Geological Adaptability: 

Performs reliably in sand, rock, clay, and wet soils across target regions.

Cost-Effective Reliability: 

Durable design minimizes maintenance and replacement costs, suitable for large-scale infrastructure projects.

RFQ Question: Do your ground pile pipes resist desert sand erosion for high-rise foundations?

Answer: Yes, our ASTM A572 Gr. 65 piles (OD 24"-60") withstand desert erosion—with optional epoxy coating for extra protection.

RFQ Question: Need corrosion-resistant piles for coastal port foundations (saltwater exposure)?

Answer: We recommend API 5L X80 marine-grade piles, engineered for saltwater corrosion resistance. They meet NACE MR0175 standards with marine compliance reports.

RFQ Question: Are your piles suitable for rocky terrain bridge piers in temperature-fluctuating regions?

Answer: Our ASTM A252 Gr. 3 piles offer high tensile strength (550MPa) for rocky terrain driving. They adapt to -10°C to 45°C fluctuations with EN 10219 certification.

RFQ Question: Can you supply large diameter (80"+) piles for industrial tank foundations in wet tropical soils?

Answer: Yes, our custom 80"-120" diameter piles (API 5L X70) are designed for wet tropical soils—thick walls (30-80mm) ensure stability.

RFQ Question: What grade of pile pipe is best for seismic-prone construction zones?

Answer: ASTM A572 Gr. 65 high-strength piles offer superior ductility for seismic zones. They absorb lateral forces, meet regional structural codes.

RFQ Question: Do your pipes support splicing for extra-long foundation requirements (over 24m)?

Answer: Yes, our piles are designed for secure welded splicing to reach 30m+ lengths. We use API 5L X70/X80 for consistency, provide splicing guidelines with technical support.
