Product introduction
Product Overview
Our 76mm–660mm HFW high-frequency straight seam welded steel tubes are specially optimized for Southeast Asia construction export markets, tailored to local infrastructure construction, municipal engineering, building structure and humid tropical climate conditions. Adopting advanced HFW high-frequency induction welding technology, this series of welded pipes features uniform weld texture, high structural rigidity, precise dimensional accuracy and excellent environmental adaptability, fully complying with Southeast Asian local construction standards and export inspection requirements.
Manufactured from premium low-carbon structural steel, the HFW welded pipe delivers stable mechanical properties, strong toughness and excellent anti-aging performance, adapting to high temperature, high humidity, rainy and humid tropical environments in Southeast Asia. The complete outer diameter range of 76mm to 660mm covers all mainstream specifications for housing construction, road engineering, municipal pipelines and factory steel structures in Southeast Asian countries. Available with black uncoated, anti-rust oil coating and hot-dip galvanized surface treatment, these export-grade steel tubes support customized processing and standardized export packaging. With stable quality and compliant export documents, they have become the preferred structural and pipeline steel tubes for long-term export supply to Vietnam, Thailand, Malaysia, Indonesia, Cambodia and other Southeast Asian regions.
Production Process
Export-Grade Raw Material Selection: Adopt qualified low-carbon steel coils that meet international export standards, with stable chemical composition and strong environmental adaptability, suitable for long-term service in Southeast Asia's humid and high-temperature tropical climate.
Precision Coil Slitting: Steel strips are slit into uniform width with strict tolerance control to ensure consistent wall thickness and symmetrical pipe body structure, meeting Southeast Asian engineering high-precision assembly requirements.
Multi-Pass Cold Forming: Continuous multi-roll precision forming ensures excellent roundness, straightness and smooth surface of pipe bodies, avoiding structural deviation during on-site construction and installation.
High-Standard HFW Welding: Optimized high-frequency induction welding process forms narrow heat-affected zones and high-integrity welds. Weld strength is equivalent to base metal, ensuring structural stability for outdoor construction in complex tropical environments.
Full Weld Bead Trimming & Polishing: Internal and external welding beads are completely removed and finely polished to eliminate stress concentration, improving pipe durability and secondary processing performance for local construction.
Online Sizing & Straightening: Closed-loop precision sizing and straightening calibrate all dimensional indicators within standard tolerance ranges, fully compliant with Southeast Asia construction project acceptance norms.
100% NDT & Hydrostatic Testing: Every finished pipe undergoes eddy current non-destructive flaw detection and high-pressure hydrostatic testing to eliminate welding defects, ensuring export-grade safety performance.
Standard Export Length Cutting: Support mainstream 6m/12m export standard lengths and customized 1.5–18m fixed lengths, adapting to local construction habits and container loading specifications in Southeast Asia.
Climate-Adaptive Surface Treatment: Provide anti-rust oil coating for short-term construction and hot-dip galvanized treatment for long-term anti-corrosion, effectively resisting moisture oxidation and rain erosion in tropical humid climates.
Export Batch Sampling Inspection: Conduct tensile, bending, flattening and anti-corrosion performance tests to ensure all indicators meet Southeast Asia market access and project acceptance standards.
