PEEK flange

PEEK flange

Core Features

  • High Strength-to-Weight Ratio: Delivers the structural bolting strength of metal flanges at a fraction of the weight, significantly reducing load on high-performance piping systems.
  • Absolute Chemical & Corrosion Immunity: Completely resistant to aggressive industrial solvents, etching acids, and saltwater, preventing the flange from seizing or degrading in harsh chemical environments.
  • Extreme Thermal Stability: Maintains a leak-proof seal and dimensional integrity in continuous operating environments up to 250°C (482°F).
  • Superior Dielectric Insulation: Naturally non-conductive, providing a safe interface for fluidic systems near high-voltage electronics or sensitive instrumentation.
  • Precision Sealing Face: Custom-machined with exacting surface finishes to ensure airtight and liquid-tight connections without the risk of metallic ion contamination.

At Kriloha Ltd., we understand that in high-pressure fluidics, the connection point is often the weakest link. Our PEEK Flanges are our engineered answer for “Leak-Proof-Security” and “Total-Environmental-Isolation”. As a premier provider of customized polymer solutions, Kriloha has developed a specialized manufacturing protocol to ensure that every flange provides a superior mechanical interface for your most critical piping architectures.

The engineering of our flanges is founded on Structural-Rigidity and Sealing-Integrity. By utilizing state-of-the-art 5-axis CNC machining, we eliminate the structural inconsistencies and parting lines often found in standard molded parts, ensuring perfectly flat sealing faces and uniform bolt-hole alignment. At Kriloha, we verify the dimensional stability of every bespoke flange under maximum thermal load, resulting in “Failure-Resistant” interfaces that do not warp or creep in high-heat environments.

Manufacturing these advanced polymer components involves strict Dimensional, Thermal, and Purity Verification. We collaborate directly with your engineering teams to process bespoke configurations—including integrated O-ring grooves, proprietary bolt patterns, and non-standard hub thicknesses. By choosing Kriloha Ltd., you are investing in a “Future-Proof” manufacturing partnership that optimizes your system’s reliability through superior material performance.

Primary Use Cases

  • Chemical Processing & Refineries: Corrosion-proof pipe connectors for systems handling highly reactive reagents and organic acids.
  • Semiconductor Manufacturing: High-purity, low-outgassing flanges used in vacuum chambers and wet-etching stations where metallic contamination is prohibited.
  • Aerospace Fluid Systems: Lightweight, high-strength fuel and hydraulic line connectors designed to survive extreme thermal cycling and vibrations.
  • Medical Diagnostic Instrumentation: Non-magnetic and radiolucent (X-ray transparent) flanges for securing fluidic paths in MRI and CT scanning environments.
  • Subsea & Geothermal Exploration: Ruggedized flange assemblies capable of withstanding high hydrostatic pressure and corrosive saltwater exposure.

Frequently Asked Questions

Why use a PEEK flange instead of Stainless Steel or Hastelloy?

Metal flanges are heavy, prone to corrosion, and can contaminate high-purity fluids. PEEK provides the strength of a high-end alloy while being lightweight, chemically inert, and non-conductive.

Can Kriloha machine flanges with specialized O-ring grooves?

Absolutely. As a customization specialist, we use precision CNC machining to create exact groove geometries (trapezoidal, rectangular, etc.) to match your proprietary sealing requirements.

Is PEEK safe for high-vacuum applications?

Yes. PEEK has exceptionally low outgassing properties, making these flanges an industry standard for semiconductor and aerospace vacuum chambers.

How does PEEK handle the mechanical torque applied during bolting?

PEEK features high compressive strength and creep resistance. When designed with proper wall thicknesses, our flanges maintain their sealing force without deforming under standard bolt torque.

Are custom layouts available for non-standard pipe diameters?

Yes. We utilize precision CNC machining to achieve sub-millimeter accuracy for any custom internal diameter, bolt-circle, or hub height required by your CAD designs.
