PEEK TUBES
PEEK Tubes are hollow, cylindrical constructions precision-engineered from Polyether Ether Ketone (PEEK)—a high-performance thermoplastic celebrated for its exceptional mechanical strength, superior chemical resistance, and outstanding thermal stability. PEEK Tubes are designed for use in harsh settings where lightweight, corrosion-resistant solutions are needed. PEEK tubes, which are made by extrusion or compression molding, are perfect for structural elements, electrical insulation, and fluid transmission in sectors like oil and gas, aerospace, and medicine.
What are the key features of PEEK Tubes?
1.UL94 V-0 rated flame retardancy (self-extinguishing).
2.High-temperature resistance: short-term exposure to 300°C; continuous use up to 250°C.
3.Low Friction: Particulate accumulation and fluid drag are decreased by a smooth inner surface.
4.Chemical Resistance: Resists steam, bases, hydrocarbons, and acids (such as sulfuric and hydrochloric).
5.Radiation Resistance: Resistant to sterilizing by electron and gamma beams.
6. Mechanical Strength: Stiffness and high tensile strength (90–170 MPa), even in designs with thin walls.
7.Biocompatibility: For implants and surgical instruments, medical grades adhere to USP Class VI and ISO 10993.
How many types of PEEK Tubes are there?
1.PEEK Tubes Filled with Carbon
-30% carbon fiber reinforcing for reduced coefficient of friction, increased strength, and wear resistance.
-Applied to high-load, high-friction components like seals, bushings, and bearings.
2.PEEK tubes that are virgin (unfilled)
-PEEK resin that is pure and unadulterated.
-Best balance of mechanical, chemical, and thermal qualities.
Fit for general industrial, food, and medical uses.
3. ESD-Safe & Conductive PEEK Tubes
-Used in the electronics, semiconductor, and aerospace industries that need electrostatic discharge (ESD) protection; contains carbon additions for electrical conductivity.
4.PEEK tubes filled with glass
-30% glass fiber reinforcement for increased stiffness and strength.
-Improves dimensional stability when under load.
-Applied in mechanical and structural applications.
5.PEEK Tubes Filled with PTFE
It is perfect for dynamic applications since it lowers wear and friction and is blended with PTFE (Teflon) to enhance self-lubrication.

4、 Chemical and corrosion resistant: able to withstand pressure, high temperatures, and strong chemicals.
5、 Electrical insulation and ESD-safe options are appropriate for high-voltage and semiconductor applications.
6、 Long Service Life: Excellent durability, impact resistance, and fatigue resistance.
7、 FDA & Medical Grade Options: Suitable for biocompatible, implantable, and food processing uses.
What applications are PEEK Tubes used for?
1、 Semiconductor: Wafer handling systems, ultra-pure gas and liquid delivery.
2、 Medical: Drug delivery systems, endoscopes, and catheters.
Dialysis machine parts and sterilizable surgical tubing.
3、 Industrial: Pneumatic systems, bearing sleeves, and high-pressure hydraulic lines.
4、 Aerospace: Electrical conduit, cryogenic fluid transfer, fuel and hydraulic lines.
5、 Oil and gas: Subsea connectors, downhole instruments, and chemical injection tubing.
How to store and handle PEEK Tubes?
1、 UV Protection: To prevent surface deterioration, shield yourself from direct sunshine.
2、 Temperature: Keep in a dry, temperature-controlled space between 15 and 25°C.
3、 Packaging: To avoid warping, store horizontally on racks and seal ends with protective covers.
4、 Humidity: To stop moisture absorption, keep the relative humidity below 50%.
5、 Shelf Life: Indefinite with no chemical deterioration if stored correctly.
Frequently Asked Questions
Question 1: Is it possible to weld or connect PEEK tubes?
A: Use compression fittings, adhesive bonding (with plasma treatment), or thermal welding.
Question 2: Can high-pressure fluids be handled by PEEK tubes?
A: Yes, CFR PEEK tubes can sustain up to 150 bar; the maximum pressure is determined by the diameter and wall thickness.
Question 3: Is it possible to mill PEEK tubes?
A: For specialized purposes, PEEK can indeed be CNC-machined, cut, and drilled.
Question 4: Can PEEK tubes be steam sterilized?
A: Yes, autoclave without deterioration for 20 minutes at 134°C.
Question 5: How can PEEK tubes be cut without burrs?
A: Use a laser cutter or a sharp blade, and use fine-grit sandpaper to deburr.
Question 6: What is the difference between PTFE and PEEK tubes?
A: In response, PEEK has a decreased chemical resistance to strong acids but a five-fold increase in tensile strength and improved thermal stability.
