Charpy Impact Test: ≥35J at -20℃, excellent low-temperature toughness, suitable for outdoor harsh environments; weld strength not lower than base metal, ensuring structural integrity

Production Process & Quality Control

Raw material inspection: Select high-quality carbon steel coils that meet API 5L and ASTM A53 standards, conduct strict chemical composition and mechanical performance testing, and implement full traceability management to ensure raw material qualification for tower load-bearing use.

Cold forming: Adopt continuous roll forming technology, precise shaping into cylindrical tube blanks, strictly control roundness and straightness, ensuring compatibility with tower connecting components and assembly accuracy.

ERW welding: Use advanced high-frequency resistance welding technology, full-automatic weld seam monitoring and control, ensure uniform weld seam, no cracks, porosity or other defects; the narrow heat-affected zone preserves material properties, making weld strength equal to or higher than the base metal.

Heat treatment: Carry out normalizing and stress relief annealing to eliminate welding residual stress, improve pipe toughness and dimensional stability, avoid deformation during tower installation and long-term use.

Precision sizing & straightening: Use professional sizing and straightening equipment to strictly control outer diameter, wall thickness and straightness within tolerance range, ensuring convenient on-site assembly and connection with tower flanges, cross arms and other components.

Non-destructive testing: Conduct full-length ultrasonic testing (UT) and eddy current testing (ECT) on the pipe and weld seam; conduct hydrostatic test, tensile test and impact test to ensure no quality defects, fully meeting the safety requirements of tower load-bearing structures.

Surface treatment & marking: Carry out hot-dip galvanizing or anti-corrosion coating according to customer requirements to enhance weather resistance and corrosion resistance; laser mark product standard, specification, steel grade, heat number and batch number for full traceability, in line with tower construction quality management requirements.

Product Advantages

Excellent Structural Strength: High tensile and yield strength, good toughness, able to withstand tower self-weight, wind load, ice load and other complex loads, ensuring long-term stable operation of the tower structure, fully meeting the load-bearing requirements of tower construction.

Superior Weld Quality: Advanced ERW welding technology, full-automatic weld monitoring, uniform and defect-free weld seam, narrow heat-affected zone, weld strength not lower than base metal, effectively avoiding structural failure caused by weld problems.
