Seamless Titanium Capillary Tube for Medical Using

LINHUI TITANIUM manufactures precision seamless titanium capillary tube for medical using compliant with ASTM B338, ASTM B337, and B861 standards. Our tubes feature outer diameters ≤8mm with customized lengths, available in biocompatible grades including Gr1, Gr2, Gr5, Gr7, Gr9, and Gr12.

The consistent development dispenses with weld creases and heat-affected zones, guaranteeing uniform microstructure all through the tube's circumference. This addresses basic challenges in restorative applications where steady divider thickness (±0.05mm resilience) and zero deformity focuses are non-negotiable for quiet security. Our controlled cold-rolling handle conveys steady mechanical properties, whereas 100% NDT review ensures pharmaceutical-grade unwavering quality for catheter conveyance frameworks and surgical instrumentation.

Key Features & Benefits

Biocompatibility Excellence

FDA-compliant Review 2 and Review 23 ELI materials shape steady TiO₂ detached layers, guaranteeing prevalent hemocompatibility in vascular environments.

Zero-Defect Structure

Seamless fabricating dispenses with erosion start focuses common in welded tubes. Your rebellious keep up basic keenness beneath cyclic sterilization loads.

Precision Tolerances

Wall thickness controlled inside ±0.05mm empowers reliable liquid flow in negligibly intrusive devices.

Superior Weariness Resistance

Homogeneous grain structure withstands over 10⁶ twisting cycles without split propagation—critical for adaptable endoscopic devices.

Product information

Manufacturing Process

Billet Selection

Premium vacuum-melted titanium ingots experience ultrasonic assessment to kill macro-defects some time recently processing.

Rotary Piercing

Solid billets change into empty shells at controlled temperatures (850-950°C) keeping up grain refinement.

Cold Pilgering

Multi-pass pilgering diminishes breadth whereas accomplishing exact divider thickness. This work-hardening prepare upgrades abdicate quality by 15-20%.

Stress Help Annealing

Heat treatment at 650-750°C optimizes ductility whereas protecting erosion resistance for your surgical applications.

Quality Inspection

· 100% Vortex Current Testing: Recognizes surface splits ≥0.1mm depth

· Ultrasonic Assessment: Confirms divider consistency per ASTM E213

· Dimensional Confirmation: CMM estimation guarantees ±0.02mm breadth accuracy

· Hydrostatic Testing: Verification weight testing at 1.5× plan pressure

· Biocompatibility Certification: ISO 10993 cytotoxicity and sensitization testing available

· Material Traceability: EN 10204 3.2 certificates with warm number tracking

Applications

Cardiovascular Devices

Guide wires, swell catheter shafts, and stent conveyance frameworks requiring wrinkle resistance and radiopacity compatibility.

Endoscopic Instruments

Working channels for laparoscopes and arthroscopes where steam sterilization cycles request fatigue-resistant materials.

Dental Implantology

Precision water system needles and osteotome sleeves profiting from titanium's osseointegration properties.

Laboratory Equipment

HPLC capillary columns and gas chromatography tubing for destructive versatile phases.

Orthopedic Tools

Drill guides and bone biopsy needles leveraging lightweight quality (45% lighter than stainless steel).

FAQ

Q: What's the minimum order quantity for custom diameters?

A: 50kg for standard grades (Gr2, Gr5). Exotic grades like Gr23 require 100kg minimums due to melting batch economics.

Q: Can you provide test samples before bulk ordering?

A: Yes. We supply 1-2 meter samples with full MTC documentation. Sample fees are credited against production orders >500kg.

Q: How do seamless tubes compare to welded tubes in fatigue performance?

A: Seamless construction eliminates HAZ stress concentrations. Independent testing shows 3-5× longer fatigue life in cyclic bending applications versus TIG-welded equivalents.

Q: Do you offer electropolishing for ultra-smooth finishes?

A: Absolutely. Our electropolishing achieves Ra ≤0.4μm surface roughness, reducing bacterial adhesion by 94% per ISO 13408 standards.

Q: What lead time for FDA-grade documentation packages?

A: Standard MTCs issue within 48 hours. Comprehensive biocompatibility dossiers (ISO 10993 series) require 15-20 business days if testing is needed.
