Corrosion at pipe supports is a major concern in industries such as oil & gas, power generation, and marine systems. I-Rod® has long been the gold standard in this area, thanks to its half-round PEEK bar design. However, ARKPEEK-1000 PEEK Half-Round Rod now presents a formidable alternative—offering comparable or superior performance at a competitive value.
Property | ARKPEEK-1000 Half-Round Rod | I-Rod® PEEK Half-Round Bar |
Resin Type | 100% PEEK Thermoplastic | 100% PEEK Thermoplastic |
Compliance | Industrial, FDA-compliant, Biocompatible | Industrial Use Proven |
Continuous Use Temp. | Up to 260°C (500°F) | Up to 249°C (480°F) |
Tensile Strength | 110–114 MPa (16,000–16,500 psi) | 110–114 MPa (16,000–16,500 psi) |
Compressive Strength | 118 MPa | 110–120 MPa |
Flexural Strength | 163 MPa | Slightly lower |
Electrical Isolation | Excellent (~18 kV/mm) | Excellent |
Creep Resistance | Very Low | Very Low |
The half-round shape minimizes contact with the pipe surface, allowing moisture to evaporate easily and preventing crevice corrosion—a major cause of pipe failure. Both ARKPEEK-1000 and I-Rod® feature this design, but ARKPEEK-1000 benefits from improved machinability and slightly higher temperature resistance.
Both materials perform excellently in resisting:
Acids and alkalis
Solvents
High-pressure steam
Mechanical abrasion
ARKPEEK-1000 also features superior wear resistance and lower friction, ensuring a longer lifespan in dynamic load environments.
ARKPEEK-1000 half-round rods are available in diameters from DN6 to DN1200, with options for custom lengths and machining to match existing I-Rod® dimensions. Installation guidelines are similar: both materials require rigid metal backings to avoid uneven loading and damage.
ARKPEEK-1000 is a true equivalent to I-Rod® in all essential areas—mechanical performance, corrosion resistance, and durability—while offering additional benefits like FDA compliance and a wider customization range.
Whether you’re specifying pipe support components for a refinery or a marine platform, ARKPEEK-1000 offers a smart, reliable, and high-performance alternative to I-Rod®.
