Engineered for heavy-duty industrial applications, our Thick Wall Black Rectangular Aluminum Seamless Pipe offers exceptional load-bearing capacity and structural integrity, ideal for machinery frames, conveyor systems, and material handling equipment. Crafted from 6061-T6 aluminum with black anodised finish, these pipes feature thick walls, seamless construction, and precise dimensions, ensuring reliability in high-stress environments.
Heavy-Duty Design
Wall Thickness: 3-15mm (10-40% thicker than standard pipes), achieving moment of inertia 30% higher than equivalent steel pipes (weight reduced by 60%).
Material: 6061-T6 (yield strength 276 MPa, tensile strength 310 MPa), compliant with ASTM B221/B221M for structural applications.
Seamless Construction
Uniform Strength: Extruded from single billet without welds, eliminating stress concentrations and improving fatigue life (10^6 cycles at 150 MPa, EN 345-1 compliant).
Surface Finish: Black anodisation (25μm, Type II) for abrasion resistance (Taber abrasion ≤5mg loss) and electrical insulation (surface resistance ≥10^9 Ω).
Dimensional & Structural Precision
Cross-Section: Rectangular (aspect ratio 1:1 to 2:1), with inner/outer corner radii ≤2mm for tight fits in modular frames.
Straightness: ≤1mm/m (laser-aligned extrusion), ensuring parallelism in multi-pipe assemblies (e.g., gantries, robotic arms).
Industrial-Grade Durability
Corrosion Resistance: Anodised surface passes 1000h salt spray (ASTM B117) and resists chemical spills (e.g., lubricants, coolants), ideal for machining environments.
Temperature Stability: Operational from -50°C to 150°C, maintaining 90% strength at elevated temperatures (tested per ISO 6892-1).
Industrial Framing: Supports for CNC machines, robotic arms, and gantry cranes, compliant with ISO 10133 structural stability standards.
Material Handling: Conveyor frames, pallet racks, and storage systems, reducing maintenance costs by 40% compared to painted steel due to corrosion resistance.
Aerospace Ground Equipment: Heavy-duty stands and tooling for aircraft maintenance, leveraging 6061-T6’s high strength-to-weight ratio (specific strength 102 MPa·m³/kg).
Load-Bearing Excellence
Finite element analysis (FEA) optimizes wall thickness for specific load cases, achieving 20% higher load capacity than off-the-shelf alternatives.
Quality Assurance
100% ultrasonic testing (UT) for internal defects and eddy current testing for wall thickness uniformity (ASTM E797), compliant with ASME BPVC Section VIII.
Custom Fabrication
In-house CNC machining for tapped holes, slots, and cutouts (tolerance ±0.1mm), with welding services (TIG/MIG) for complex assemblies (ISO 3834-2 certified).
Industry Compliance
Certified to EN 1090-1 EXC3 and AWS D1.2 for aluminum welding, ensuring use in safety-critical applications like machinery guarding (ISO 14120).
