Product introduction
Product Overview
Our 76–660mm high frequency straight welded tubes are heavy-duty structural steel pipes specially designed for crane base support and mechanical engineering load-bearing systems. Adopting mature high-frequency electric resistance straight welding technology, this series of structural pipes features high tensile strength, excellent rigidness, stable welding integrity and strong anti-deformation performance, fully meeting the long-term heavy-load bearing, vibration resistance and structural stability requirements of crane base fixed support systems.
Manufactured from premium low-carbon high-strength structural steel, the straight welded tubes deliver uniform pipe body texture, outstanding compression resistance and fatigue resistance, adapting to complex working conditions such as mechanical vibration, dynamic load impact and long-term static pressure bearing of tower cranes, truck cranes and engineering cranes. The complete outer diameter range of 76mm to 660mm covers all mainstream specifications for crane base support pipes, equipment foundation structural tubes, mechanical frame load-bearing components and engineering machinery auxiliary supports. Available with black uncoated, anti-rust oil coating and hot-dip galvanized surface treatment, these structural tubes support customized wall thickness reinforcement and fixed-length cutting. With reliable load-bearing performance and high structural stability, they are ideal structural pipe solutions for crane manufacturing, mechanical equipment processing and engineering machinery renovation projects worldwide.
Production Process
Heavy-Duty Structural Grade Raw Material Selection: Adopt high-strength low-carbon steel coils with stable chemical composition and high purity, ensuring excellent load-bearing capacity and mechanical stability for crane base heavy-load structural service.
Precision Coil Slitting: Steel strips are slit with ultra-tight tolerance control to ensure uniform wall thickness and symmetrical pipe body structure, avoiding local stress concentration under heavy load.
Multi-Pass Heavy-Duty Cold Forming: Continuous multi-roll reinforced cold forming ensures perfect roundness and ultra-high straightness, guaranteeing overall structural balance of crane base support frames.
High-Frequency Straight Welding Molding: Optimized heavy-load welding parameters form high-density, defect-free straight welds. The weld strength is completely consistent with the base metal, effectively resisting structural cracking under long-term mechanical vibration and heavy pressure.
Full Internal & External Weld Bead Polishing: All welding burrs and beads are thoroughly trimmed and finely polished to eliminate weak structural points, improving the overall fatigue resistance and service life of crane structural parts.
Online Precision Sizing & Straightening: Secondary precision calibration and straightening treatment strictly control dimensional tolerance, ensuring high-precision assembly and stable docking of crane base structures.
100% NDT & Pressure Resistance Testing: Each pipe undergoes eddy current non-destructive flaw detection and hydrostatic pressure testing to eliminate internal and welding defects, ensuring zero structural failure under heavy load.
Standard & Custom Fixed-Length Cutting: Support standard 6m/12m lengths and customized 1.5–18m fixed lengths to adapt to different crane base size specifications and mechanical structural design requirements.
Targeted Surface Anti-Corrosion Treatment: Optional anti-rust oil coating and hot-dip galvanized treatment prevent oxidation and corrosion, suitable for indoor workshop production and outdoor crane equipment long-term placement.
Heavy-Load Performance Sampling Inspection: Conduct tensile, compression, bending and fatigue resistance tests to verify that the pipes fully meet crane mechanical structural load-bearing standards.
