Need a specific diameter, coating, or length? We offer OEM/ODM services, including samples for quality verification. Our 100,000+ ton annual inventory ensures quick turnaround, even for bulk orders.
Choose from SSAW Carbon Steel Pipes anti-corrosion coatings like 3PE, FBE, or galvanized finishes. Hydrostatic testing and ultrasonic inspections guarantee weld seam integrity, even under temperature fluctuations.
Reduced welding points in long-length pipes (up to 12m) mean faster installation and lower labor costs for projects like bridge construction or municipal water systems.
Every batch undergoes rigorous checks:
1. Hydrostatic Testing: Verifies pressure resistance up to 25MPa.
2. Ultrasonic Inspection: Detects micro-defects in weld seams.
3. Dimensional Accuracy: Laser-guided measurements for precision.
