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.
