SSAW Steel Pipe

1. Raw Material Preparation: 

Inspection and cutting of hot-rolled steel strips (carbon steel/HSLA) to required widths.

2. Coiling & Forming: 

Helical coiling of steel strips into cylindrical shape using precision forming equipment.

3. Submerged Arc Welding: 

Dual-sided SAW to create uniform, crack-resistant spiral seams—ensuring weld integrity for high-pressure applications.

4. Sizing & Straightening: 

Calibration to guarantee roundness, straightness, and dimensional accuracy.

5. Non-Destructive Testing (NDT): 

Ultrasonic (UT) and radiographic (RT) testing to detect weld defects.

6. Hydrostatic Testing: 

Pressure testing to verify leak-proof performance for fluid transmission.

7. Surface Treatment: 

Application of optional anti-corrosion coatings (3PE/FBE/galvanized) based on regional environmental needs.

8. Final Inspection: 

Visual, dimensional, and mechanical property checks before packaging.

Superior Strength: 

High tensile and yield strength, ideal for API 5L gas welded pipe procurement and high-pressure oil/gas transmission.

Cost-Effective: 

Lower production costs than LSAW for large diameters, fitting budget constraints of African and Southeast Asian projects.

Flexible Sizing: 

219mm-3000mm diameter range meets large diameter water pipeline and structural needs across regions.

Excellent Weldability: 

Spiral SAW ensures uniform seams, suitable for Welded Structural pipe in bridges and buildings.

Corrosion Resistance: 

Optional 3PE/FBE/galvanized coatings withstand Middle East salt spray and Southeast Asian humidity.

Durable: 

Weather-resistant grades (ASTM A588) adapt to outdoor use in harsh regional climates.

Our SSAW steel pipes comply with global and regional standards for seamless project approval:

• International Standards: API 5L (PSL1/PSL2), ASTM A252, EN 10219, GB/T 9711, ISO 3183
• Quality Management: ISO 9001
• Regional Compliance: SASO (Middle East), SONCAP (Africa), SNI (Indonesia), TIS (Thailand)
• All orders include NDT reports, material test certificates (MTC), and compliance documents for customs clearance.

Packaging

• Pipes are bundled with high-strength galvanized steel straps to prevent deformation during transit.
• Plastic caps are fitted on pipe ends to protect against rust, dust, and moisture.
• Wrapped in moisture-proof film for humid regions (Southeast Asia/Africa) and anti-corrosion paper for desert areas (Middle East).
• Placed on ISPM 15-certified wooden pallets for international shipping compliance.
• Clear English labeling includes product name, grade, specs, batch number, and handling instructions.

Shipping

• Lead Time: Standard orders (≤200 tons): 15-25 working days; Bulk orders (＞200 tons): 25-35 working days; Customized orders: 20-30 working days.
• Logistics Partners: Maersk, CMA CGM (global), Aramex (Middle East), SICEPAT (Southeast Asia), GIGL (Africa).
• Delivery Coverage: Port-to-port, door-to-door for major cities, and inland transport to remote project sites.
• Special Arrangements: Oversize pipe (OD ≥2000mm) shipping coordinated with regional authorities for permits.

RFQ Question: Can your API 5L X70 SSAW pipe resist UAE’s coastal salt spray, and what’s the delivery time?

Answer: Yes, our API 5L X70 SSAW pipe comes with 3PE coating (salt spray resistance ≥1000h) for UAE’s climate. Standard delivery time is 18-25 working days, with SASO certification included.

RFQ Question: What’s the warranty for SSAW pipes used in Nigeria’s water pipeline project?

Answer: We offer a 12-year warranty against manufacturing defects and corrosion (for coated pipes) for Nigeria’s water pipeline. The API 5L X52 pipes are SONCAP-approved, with free technical support if issues arise.

RFQ Question: Need Welded Structural pipe for Thailand’s bridge—can it withstand tropical rains?

Answer: Our ASTM A36 SSAW pipe (Welded Structural pipe) is treated with FBE coating to resist Thailand’s humidity. Delivery time is 15-20 working days, and it meets TIS standards for bridge construction.

RFQ Question: What’s the lead time for bulk API 5L gas welded pipe procurement in Iran?

Answer: For bulk orders (＞200 tons) of API 5L X65 SSAW pipe, lead time is 25-30 working days. We provide Persian/English documents, API 5L PSL2 certification, and assist with Iranian customs clearance.

RFQ Question: Do your SSAW pipes for Kenya’s rural water project have a moisture-proof package?

Answer: Yes, pipes for Kenya’s rural projects are wrapped in moisture-proof film and wooden pallets to withstand tropical rains. The large diameter water pipeline (API 5L X42) has a 10-year warranty, with delivery in 20-28 working days.
