Material
The ST52 triangle pipe is a seamless, high-strength structural steel tube characterized by its uniform "lemon" (triangular) cross-section. Manufactured through hot extrusion and precision cold drawing, it delivers excellent dimensional accuracy, smooth internal surfaces, and superior mechanical properties suitable for demanding agricultural shaft applications.
Detailed Specifications
  • Shape: Equilateral triangular ("lemon") cross-section
  • Grade: ST52 (per EN 10210/10219)
  • Production Method: Hot extrusion + cold drawing (seamless)
  • Dimensions:
    • Side length (a): 30 mm-100 mm (customizable)
    • Wall thickness (t): 2 mm-8 mm
    • Length: 3 m-12 m (standard)
  • Surface Finish: Mill finish or optional black oxide coating
  • Tolerance: ±0.2 mm on side length; ±0.15 mm on thickness

Key Features
  • High Strength-to-Weight Ratio: Optimized alloy chemistry delivers excellent load-bearing capacity at reduced weight.
  • Seamless Integrity: Manufactured without weld seams for uniform stress distribution and fatigue resistance.
  • Dimensional Precision: Tight tolerances ensure consistent fit and alignment in shaft assemblies.
  • Surface Quality: Smooth internal/external walls minimize wear on bearings and seals.
  • Corrosion Resistance: Optional coatings or post-treatments extend service life in harsh agricultural environments.
Applicable Standards
  • ASTM: ASTM A572/A572M, ASTM A106/A106M
  • EN: EN 10210, EN 10219, EN 10025-2
  • GOST: GOST 8732-78 (seamless tubes)
  • JIS: JIS G3444 (carbon steel tubes)
  • GB: GB/T 12771, GB/T 8162
Application Domains
Agricultural Machinery Shafts
  • Tractor Drive Shafts: Transmit torque from engine to drivetrain via triangular spline fittings.
  • Combine Harvester Shafts: Provide power take-off interfaces for header and threshing units.
  • Plow Frame Connectors: Act as rigid couplings between plow beams and hydraulic actuators.
  • Seeder Drive Shafts: Ensure precise, backlash-free rotation for seed metering assemblies.
  • Rotary Tiller Shafts: Deliver robust torque to tillage tines in corrosive soil conditions.
