Lemon-shaped tube

Key Design Features:

1. Unique Lemon-Shaped Geometry

  • Optimized Cross-Sectional Design – The distinctive lemon profile provides 15-20% greater torsional rigidity compared to standard round tubes of equivalent weight

  • Enhanced Flow Characteristics – Streamlined internal geometry minimizes turbulence and pressure drops in fluid transfer applications

  • Directional Stability – The flattened surfaces prevent unwanted rotation during assembly and operation

  • Space-Efficient Packaging – Compact profile allows tighter bundling and reduced installation footprint

2. Precision Manufacturing Process

  • CNC Roll-Forming Technology – Automated forming ensures consistent wall thickness (±0.1mm) and precise dimensional control

  • High-Strength Materials – Manufactured from ST37, ST52, 304/316 stainless steel, or custom alloys per application requirements

  • Seamless or Welded Construction – Options include DOM (Drawn Over Mandrel) seamless tubing or high-frequency welded tube with complete weld integrity

  • Surface Finish Options – Available in pickled, polished, phosphated, or powder-coat ready finishes

3. Superior Mechanical Properties

  • Wall Thickness Range – 1.5mm to 6.0mm customizable to pressure and load requirements

  • High Yield Strength – 235-355 MPa standard, with high-strength variants up to 500 MPa available

  • Excellent Fatigue Resistance – Optimized for cyclic loading applications in suspension and steering systems

  • Operating Temperature Range – -40°C to +120°C standard, with high-temperature variants available

4. Application-Specific Engineering

  • Fluid Conduit Systems – Ideal for hydraulic lines, pneumatic circuits, and coolant circulation

  • Structural Frameworks – Used in roll cages, chassis components, and machinery frames requiring asymmetric strength

  • Agricultural Implements – Perfect for seeders, sprayers, and harvesting equipment tubing

  • Automotive Specialty Parts – Custom exhaust components, intake manifolds, and suspension elements

5. Versatile Configuration Options

  • Standard Lemon Profile – Classic two-lobed geometry for general-purpose applications

  • Extended Flat Sections – Modified profiles with increased surface contact areas for mounting

  • Tapered Transitions – Gradual cross-section changes for connecting to round or square tubing

  • End Treatment Options – Flared, swaged, threaded, or welded end preparations available

  • Cut-to-Length Service – Precision cutting with deburring and end-finishing included
