Product Detail

Shanghai Metal Corporation is a leading PEEK Tube / Pipe manufacturer and supplier.

PEEK tube / pipe is hollow semi‑finished profile made from polyetheretherketone engineering polymer. It can be produced via extrusion, hot compression molding or short‑run injection molding. Different filler formulations including carbon fiber, glass fiber are blended into base PEEK resin to adjust rigidity, friction performance and dimensional stability. These hollow profiles are further CNC‑machined into sleeves, bushings, fluid transfer liners and insulating spacers. It replaces metal tubing in working environments demanding weight reduction, resistance to hot steam and aggressive chemical fluids. This material avoids rust and metallic particle contamination. It supports both stock standard dimension and fully custom outer diameter, inner diameter and cut‑to‑length according to mechanical and fluid system requirements.

If you want to know more about our PEEK products or PEEK tube price please feel free to contact us, we will reply you within 24 hours.

PEEK tube belongs to polymer hollow profile semi‑finished material. Base raw material is unfilled virgin PEEK resin. Carbon fiber, glass fiber or solid lubricant fillers are compounded to produce modified grades.
1. Unfilled Virgin PEEK: Natural grey color, maintains high impact toughness and material purity. Fit for scenarios requiring biocompatibility and non‑contamination for fluid contact.
2. Carbon‑fiber filled PEEK: Black appearance, improved tensile strength and low thermal expansion. Suitable for high‑pressure, high‑load mechanical bushing and down‑hole industrial parts.

3. Glass‑fiber filled PEEK: Slight brownish tone, enhanced rigidity and anti‑creep property, cost‑effective for general‑purpose structural sleeves under continuous high‑temperature load.
4. Lubricant modified compound PEEK: Added PTFE solid lubricant, lowers friction coefficient, for sliding bushing components under dry‑running working state.
Different manufacturing processes also create structural differences:
‑Extruded PEEK tube: Suitable for small‑to‑medium OD, long continuous length, high volume production.
‑Hot‑compression‑molded PEEK tube: For large outer diameter and thick‑wall sizes which cannot be achieved by extrusion.
‑Injection‑molded PEEK tube: Only applies for short‑length thin‑wall small‑diameter parts for small‑batch components.

High Temperature Long‑Term Working Performance
Retains core mechanical properties under continuous operating temperature up to 260℃. Helps component maintain dimension stability inside high‑heat equipment without frequent part replacement.
Chemical and Hydrolysis Resistant Polymer Structure
Resists most organic solvents, weak acid, alkali and repeated hot‑steam exposure. Prevents tube swelling or cracking in chemical fluid transport and steam sterilization cycles.

Tunable Mechanical Strength By Material Formulation
Users can select unfilled or fiber‑filled grades. Carbon‑fiber reinforced grades improve pressure bearing capacity, while unfilled grades keep high impact resistance. It allows engineers to match material performance with actual load conditions instead of over‑specifying raw materials.
Good Machinability For Secondary Processing
Extruded and compression molded PEEK tube can be cut, bored, turned and milled on CNC lathe. Customers can machine finished sleeves, liners and spacers directly from semi‑finished tube stock, reducing mold opening investment for prototype and small‑batch orders.
Light‑Weight Metal Substitution Property
Density is far lower than steel, brass or stainless steel pipe. It lowers total assembly weight for mobile equipment such as aerospace and down‑hole instruments and reduces overall system load.

POil & Gas Down‑hole Instrument Liner
Suitable for inner protective liners of well‑logging instruments working underground. It withstands high temperature, hydrocarbon fluid and brine corrosion. Carbon‑fiber filled PEEK tube is recommended for high‑pressure down‑hole working condition.
Medical Analytical Instrument Fluid Tubing
Used for liquid flow pipelines inside laboratory analysis and diagnostic equipment. Unfilled virgin PEEK keeps fluid purity and tolerates repeated autoclave sterilization. Unfilled natural PEEK grade is preferred for direct‑fluid‑contact assemblies.
Semiconductor Equipment Insulating Sleeve
Applied as insulating and isolating hollow sleeves for semiconductor processing equipment. It maintains stable dielectric property under high‑temperature clean environment. Unfilled or glass‑fiber filled PEEK tube are common selections.
Chemical Processing Fluid Transfer Liner
Serves as inner lining for small‑bore piping transporting corrosive chemical medium. It avoids chemical erosion attacking metal base pipe. Wall thickness shall be increased when working under high‑pressure chemical circulation.

Production Process Flow

PEEK raw pellet melting & compounding → Extrusion / Hot compression molding → Slow cooling stress‑relief annealing → Saw cutting to length → Dimension inspection → Surface finishing → Sorting for stock or shipment.

Standard Packaging

Each tube end is fitted with plastic end protective caps to prevent end‑face chipping and scratch. Single or multiple tubes are wrapped with anti‑static kraft paper and bubble foam. Short pipe segments are separated by foam partitions inside thick export corrugated cartons. Long‑length tubes are fixed inside reinforced plywood wooden cases with foam filling to avoid shifting and collision. Finished cartons or wooden cases are stacked on fumigated wooden pallets and fully wrapped with stretch film. Outer package labels mark material grade, OD‑ID dimension, batch number and quantity for product identification.

How to identify PEEK materials?

The easiest way to distinguish PEEK materials, whether profiles or raw materials, is through temperature resistance. PEEK's thermal deformation temperature is 343 degrees Celsius. It can be easily distinguished by setting the temperature at 330 degrees Celsius in the oven for half an hour. There is also pure PEEK, the color is off-white, graphite PEEK with carbon fiber is black, and glass fiber is brown.

FAQs:

Q1: How long does sample preparation take for PEEK tube /pipe?

A: If we have matching stock semi‑finished tube, samples take 3‑7 working days. For non‑standard custom OD‑ID size requiring dedicated molding, sample lead‑time will extend to 10‑15 working days.

Q2: What information do you need for PEEK tube quotation?

A: Please provide outer diameter, inner diameter, wall thickness, required length, PEEK material grade, total quantity and special tolerance requirements. Drawings are preferred for custom‑machined finished parts.

Q3: What is the MOQ and production lead‑time?

A: MOQ is 1 PC for prototype testing. Stock dimension orders take 15‑25 working days; non‑standard custom dimension orders take 25‑40 working days.

Q4: Can you cut PEEK tube into finished machined sleeves or bushing parts?

A: Yes, we offer secondary CNC turning and boring service based on our PEEK tube semi‑finished material, you need to provide finished‑part 2D drawing for evaluation and quotation.

Q5: What factors shall I consider to choose extrusion or hot‑compression‑molded PEEK tube?

A: Extrusion fits small‑medium OD, thin‑to‑medium wall, long‑length mass‑volume orders. Hot compression molding is required for large outer‑diameter and super‑thick‑wall specifications which cannot be extruded, with higher unit cost and longer production cycle.

Q6: What quality standards can PEEK tube comply with?

A: Raw material performance follows ISO test standards. Batch‑wise material test report can be supplied. Special certifications such as FDA‑compliant material documents can be arranged upon customer project request.
