Our LSAW (Longitudinal Submerged Arc Welded) pipe workshop is a premier manufacturing hub specifically designed for heavy-duty structural and high-pressure fluid transmission applications. By utilizing the advanced JCOE (J-ing, C-ing, O-ing, Expansion) forming process, we deliver high-precision piping solutions for the world’s most demanding energy and infrastructure projects.
Automated JCOE Production: Our facility features a fully automated and continuous JCOE production line. This integrated system ensures seamless transitions from plate milling and forming to multi-wire submerged arc welding, minimizing manual intervention and maximizing structural consistency.
Product Range:
Outer Diameter (OD): 406mm – 1422mm
Wall Thickness (WT): 6mm – 100mm
Specialty: We possess extensive experience in producing heavy-wall thickness pipes, engineered to withstand extreme pressures and harsh environments.
Annual Capacity: Our workshop maintains a formidable annual production capacity of 300,000 metric tons.
Warehousing & Logistics: We operate a vast, specialized warehouse area of 20,000 square meters, ensuring optimized inventory management and rapid dispatch for global shipments.
To guarantee "Super Quality," our LSAW pipes undergo a comprehensive inspection regimen that exceeds standard international requirements (such as API 5L, ASTM, and EN standards).
Key Inspection Systems:
Full-Length Mechanical Expansion: Every pipe undergoes cold mechanical expansion to improve dimensional accuracy and relieve internal stress.
100% Non-Destructive Testing (NDT):
Automatic Ultrasonic Testing (UT): Continuous scanning of the weld seam and pipe ends.
X-Ray Inspection: Digital radiographic testing to ensure the internal integrity of every weld.
Hydrostatic Testing: Each unit is subjected to high-pressure water testing to verify leak-proof performance.
Precision Lab Analysis: On-site chemical composition analysis and mechanical testing (Tensile, Impact, Hardness, and Flattening) to verify material grade compliance.
