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
