Chemical and hydrolysis resistance are also critical factors for customers during the selection process. PEEK tubing withstands the vast majority of mineral oils, hydraulic fluids, organic acids, weak bases, and hydrocarbon solvents; it exhibits excellent hydrolytic stability and minimal strength degradation during long-term use in high-temperature steam environments. Only strongly oxidizing media, such as concentrated nitric acid, cause material degradation, so the conveyed medium must be verified during project selection. The smooth inner wall minimizes fluid resistance and prevents residue buildup, significantly simplifying cleaning and maintenance.
Its mechanical and insulating properties are equally outstanding. Compared to stainless steel, PEEK tubing offers a weight reduction of approximately 70%, providing a clear advantage in lightweighting and reducing the load on the overall equipment assembly. Even thin-walled versions retain impressive pressure resistance, making them suitable for high-pressure fluid lines. The material's stable dielectric properties and excellent insulation make it a preferred choice for high-voltage equipment and downhole insulation sheathing. Medical-grade PEEK tubing offers excellent biocompatibility and withstands repeated sterilization via gamma radiation or high-temperature steam, making it ideal for use in minimally invasive instruments and fluid delivery lines for analytical equipment.
We offer both unfilled PEEK tubing and grades modified with carbon fiber or glass fiber. Carbon fiber-reinforced versions provide enhanced rigidity and wear resistance, while glass fiber-modified tubing offers superior dimensional stability. We offer a wide range of PEEK tubing sizes, customizable from ultra-fine 1/16-inch capillaries used in chromatography instruments to large-diameter industrial casings. Our products feature strict tolerance controls for inner/outer diameters and wall thickness, high concentricity, and a structure free from voids or delamination. Tubing can be cut to specific lengths, and small-batch samples are available for initial testing and validation.
To meet the complex demands of various industrial applications, our PEEK tubing production processes and specifications are highly mature:
Advanced Continuous Extrusion: High-quality PEEK tubing is typically produced via automated continuous extrusion. This process significantly boosts production efficiency and overcomes technical challenges associated with traditional methods-such as the limitations of compression molding and the internal shrinkage voids often found in injection molding-ensuring smooth inner and outer surfaces and exceptional dimensional stability.
Comprehensive Size Range and Precision Tolerances: We offer an extensive range of specifications, spanning from micro-capillaries with a 6mm outer diameter (OD) to large industrial tubes with a 550mm OD, and wall thicknesses ranging from 0.8mm to 5mm. Whether the application requires precision fluid control with tight tolerances or large-diameter structural support, we can provide high-precision customization.
Ease of Secondary Processing and Forming: PEEK tubing features a smooth surface and low frictional loss, making it ideal for secondary processing. It can be bent, flared, and thermoformed using standard heating equipment and supports various mechanical connections-such as crimping and clamping-greatly simplifying the design and assembly of complex piping systems.
Each batch of PEEK tubing comes with a comprehensive physical property test report. For projects in the medical, semiconductor, and oil & gas sectors, we can assist in preparing the necessary certification documents to meet the quality inspection and audit requirements of overseas clients.
