Structural & Conveyance Welded Pipe

1. Raw Material Preparation:

Selection of high-quality steel coils/strips (carbon/low-temperature/high-strength) to meet Construction welded pipe and fluid conveyance standards.

2. Forming:

Precision roll-forming into cylindrical/special profiles, ensuring dimensional accuracy for building construction steel pipe integration.

3. Welding:

HFIW or ERW techniques to create durable seams with mechanical properties matching base metal—critical for Welded Structural pipe reliability.

4. Sizing & Straightening:

Mechanical calibration to tight tolerances, enabling easy installation in construction and large diameter water pipeline projects.

5. Optional Heat Treatment:

Annealing/normalizing for high-strength grades, enhancing performance in extreme climates.

6. Surface Treatment:

Burr-free finishing, compatible with painting, coating, or galvanizing to boost corrosion resistance for regional conditions.

7. Quality Testing:

Dimensional checks, hydrostatic pressure testing, and ultrasonic (UT) inspection to verify compliance for API 5L gas welded pipe procurement and structural use.

8. Packaging:

Preparation for regional shipping with climate-adapted protection.

Dual-Purpose Versatility:

Serves as both Construction welded pipe (load-bearing columns/beams) and fluid conveyance pipe (large diameter water pipeline, API 5L gas welded pipe).

High Structural Integrity:

Welded seams ensure uniform strength, meeting building construction steel pipe requirements for heavy-load applications.

Superior Weldability:

Enables on-site fabrication (bending, flanging) to adapt to diverse project designs across target regions.

Cost-Effective:

More economical than seamless pipes, ideal for large-scale construction and infrastructure projects as a trusted construction steel pipe supplier.

Climate Adaptability:

Resists desert heat, coastal humidity, and tropical rains—with galvanized/coated options for enhanced corrosion protection.

Dimensional Precision:

Tight tolerances ensure seamless integration in construction frameworks and fluid transport systems.

Our Structural & Conveyance Welded Pipe complies with global and regional standards for project approval:

• International Standards: API 5L (for gas welded pipe), ASTM A53/A500/A252/A333, EN 10219/EN 10255
• Quality Certification: ISO 9001
• Regional Compliance: SASO (Middle East), SONCAP (Africa), SNI (Southeast Asia), ISIRI (West Asia)
• All orders include material test certificates (MTC) and compliance documents for customs clearance and API 5L gas welded pipe procurement verification.

Packaging

• Pipes are bundled with high-strength steel straps to prevent deformation during transit.
• Fitted with plastic caps on ends to protect against rust, dust, and moisture—critical for large diameter water pipeline and construction pipe.
• Wrapped in moisture-proof film for humid regions (Southeast Asia/Africa) and anti-corrosion paper for deserts (Middle East).
• Placed on ISPM 15-certified wooden pallets for international shipping compliance.
• Clear labeling includes product type (e.g., Construction welded pipe, API 5L gas pipe), grade, specs, and batch number.

Shipping

• Lead Time: Standard orders (≤200 tons): 12-20 working days; Bulk orders (＞200 tons): 20-30 working days; Custom API 5L gas welded pipe procurement: 15-25 working days.
• Logistics Partners: Maersk, CMA CGM, Aramex (Middle East), SICEPAT (Southeast Asia), regional carriers for inland delivery to construction sites.
• Delivery Coverage: Port-to-port, door-to-door for major cities, and tailored solutions for remote infrastructure projects.

RFQ Question: Do your Welded Structural pipes resist desert heat for high-rise construction?

Answer: Yes, our ASTM A500 Gr. C pipes withstand 55°C+ desert heat and heavy loads. As a construction steel pipe supplier, we offer galvanized options for dust resistance—ideal for building frames.

RFQ Question: Need large diameter water pipeline pipes—can they handle tropical rains and humidity?

Answer: Our ASTM A53 Gr. B pipes (OD 200-600mm) come with anti-corrosion coating to resist tropical conditions.

RFQ Question: Are your pipes compliant with API 5L for gas welded pipe procurement in temperature-fluctuating regions?

Answer: Yes, our API 5L X52/X60 pipes meet PSL1/PSL2 standards for gas transport. They adapt to -10°C to 45°C fluctuations, with ISIRI compliance for West Asia.

RFQ Question: What grade of building construction steel pipe is suitable for bridge load-bearing in seismic-prone areas?

Answer: We recommend ASTM A500 Gr. C high-strength welded pipes—excellent load-bearing and ductility for seismic zones. They meet regional structural standards.

RFQ Question: Do your pipes support large-scale API 5L gas welded pipe procurement for rural distribution networks?

Answer: Our API 5L X42 pipes are cost-effective for rural gas distribution, with medium-pressure resistance and easy installation. They’re compatible with regional infrastructure, delivering in 15-20 working days with batch pricing.
