Hongwo FRP Structural Tubes: Redefining Load-Bearing Excellence

Manufactured through our proprietary multi-axis pultrusion process, these fiber-reinforced polymer tubes combine carbon fiber strands with isopolyester resin for exceptional torsional rigidity. Unlike conventional fiberglass pipes, our formulation achieves 92% fiber volume fraction – verified through micro-CT scanning at Hongwo‘s Qingdao testing facility.

Engineering Specifications

Material Composition:

• 65% T700S carbon fibers (Toray certified)
• 35% corrosion-resistant resin matrix
• Optional aramid fiber reinforcement layers

Performance Benchmarks:

✓ 2,400 MPa flexural strength (ASTM D790)

✓ 1.8 g/cm³ density (56% lighter than steel)

✓ -40°C to 150°C operational range

Comparative Advantages

Hongwo’s composite tubing outperforms traditional materials in:

• Fatigue resistance (1 million cycles at 60% ultimate load)
• EMI shielding (40 dB attenuation at 1GHz)
• Lifecycle cost (72% lower than stainless steel over 15 years)

Case Study: Arctic Pipeline Support System

When thermal contraction fractured aluminum supports in Alaska, our FRP structural tubes:

Maintained dimensional stability at -55°C

Reduced ice load accumulation by 43%

Eliminated galvanic corrosion issues

Quality Control Measures

Every production run includes:

Automated fiber orientation analysis (3D laser scanning)

Void content measurement (<0.5% by volume)

Full-length ultrasonic inspection

Installation Best Practices

For optimal field performance:

• Use nylon-coated clamps to prevent surface damage
• Allow 0.15% linear expansion per 10°C ΔT
• Specify fire-retardant variants for tunnel applications

…from offshore platforms to chemical processing plants, Hongwo’s FRP structural tubes deliver uncompromising reliability.
