Product introduction
1.Short Description (Banner & Search Preview)
This series of high-frequency welded tubes features an outer diameter range of 76mm to 660mm, specially customized for wind power support frame engineering. Adopting advanced HFW high-frequency resistance welding technology and low-carbon steel raw materials, the pipe body has high structural stability, strong compression resistance and excellent weather resistance. Strict dimensional tolerance control and full non-destructive testing ensure reliable bearing capacity for wind turbine support, wind power station infrastructure and offshore wind auxiliary structures. Factory direct sales, customizable specifications and surface anti-corrosion treatment to adapt to harsh outdoor and marine wind power working environments.
2.Product Overview
Professional Wind Power Support HFW Welded Tube
76mm~660mm high frequency welded pipe is a high-strength structural steel tube developed specifically for the wind power industry. Different from ordinary construction steel pipes, this product focuses on high stability, strong wind resistance, anti-fatigue and long-service-life performance, perfectly matching the force-bearing characteristics of wind power support frames, turbine brackets and wind farm foundation supports.
Manufactured by high-frequency welding (HFW/ERW) process, the steel pipe forms integrated metallurgical welding seams without welding filler. The weld strength is consistent with the base metal, with smooth inner and outer walls, uniform wall thickness and excellent straightness. Made of high-quality low-carbon steel, it has outstanding ductility, impact resistance and secondary processing performance, which can effectively resist strong wind vibration, temperature difference changes and outdoor corrosion, and is the preferred structural pipe for onshore and offshore wind power support projects.
3.Core Product Advantages (Wind Power Specialized)
✅ Wind Power Grade High Structural Stability
Optimized low-carbon steel formula and professional structural rolling process improve the overall rigidity and compression resistance of the pipe body. It can withstand long-term wind vibration and alternating load impact, effectively avoid structural deformation and cracking, and meet the long-term safe operation requirements of wind power support frames.
✅ 76-660mm Full Size Coverage for Wind Engineering
Complete outer diameter specifications from 76mm to 660mm, matched with 1.5mm-20mm optional wall thickness, covering all conventional size requirements of wind power support brackets, diagonal supports and foundation steel structures. Strict ovality and straightness tolerance ensures accurate assembly of wind power frame structures.
✅ Superior Weld Quality & Anti-Fatigue Performance
Advanced HFW high-frequency welding technology eliminates weak welding areas. The inner and outer weld beads are smoothly polished, with no weld gaps or stress concentration. After multiple fatigue tests, the pipe body maintains stable performance under long-term dynamic load, adapting to the special working conditions of wind power equipment.
✅ Custom Anti-Corrosion for Harsh Wind Environments
Support multiple surface anti-corrosion treatments including hot-dip galvanizing, 3LPE anti-corrosion, epoxy coating and anti-rust oil. It effectively resists outdoor ultraviolet erosion, rainwater corrosion and offshore salt spray corrosion, greatly extending the service life of wind power support frames up to 20-30 years.
✅ Strict Industry Standard Inspection & Certification
All products pass 100% online ultrasonic NDT inspection, hydrostatic pressure test, bending and flattening mechanical tests. Comply with international wind power structural steel standards, providing complete 3.1 MTC test reports and supporting SGS/BV/TUV third-party inspection for wind power project bidding and acceptance.
