Titanium Alloy Pipe
LINHUI TITANIUM specializes in manufacturing high-performance titanium alloy pipe with exceptional corrosion resistance and strength-to-weight ratios. Our seamless and welded pipes meet ASTM B861/B862 standards, featuring thickness tolerance controlled within ±0.05mm through precision cold rolling technology. With 100% NDT inspection (ultrasonic and eddy current testing), we guarantee zero-defect delivery. Our comprehensive inventory includes Grade 2, Grade 5 (TC4), Grade 7 (palladium-enhanced), and Grade 9, with tensile strengths ranging from 345 MPa to 900 MPa. Operating from our Xi'an facility since 2000, we maintain 200+ tons stock for immediate shipment and offer quotation responses within 4 hours, supporting projects across 60+ countries.
Key Features & Benefits
Our item conveys unmatched toughness in forceful situations. Review 7 consolidates 0.12–0.25% palladium, giving prevalent hole erosion resistance in hot brine and moo pH conditions over 80°C.
Grade 5 (TC4) offers three times the quality of commercially immaculate titanium, perfect for high-pressure water powered frameworks. The consistent development dispenses with weld frail focuses, whereas welded variations keep up base metal properties without filler contamination.
You advantage from uncommon formability and weldability over all grades. Our fabric withstands persistent operation up to 400°C with negligible warm extension, decreasing framework push amid temperature cycling.

Manufacturing Process
We utilize controlled cold rolling to accomplish exact dimensional precision for your basic applications. The consistent pipe generation starts with vacuum circular segment remelting (VAR) to dispense with impurities.
Hot expulsion shapes the beginning billet, taken after by multi-pass cold pilger rolling. This prepare refines grain structure, improving weariness resistance. Welded channels utilize programmed TIG welding in argon-shielded chambers, anticipating oxygen contamination.
Stress-relief strengthening at 650-750°C evacuates leftover stresses without changing microstructure. Last pickling in HNO₃-HF arrangement expels alpha case layers. Each group experiences warm number following for total traceability per EN 10204 3.1/3.2 requirements.
Quality Inspection
Your channels experience thorough 100% ultrasonic testing (UT) to identify inner laminar abandons undetectable to visual review. Whirlpool current testing (ET) confirms welded crease astuteness over the whole length.
Positive Fabric Distinguishing proof (PMI) spectroscopy affirms combination composition at numerous focuses. Smoothing and flaring tests approve ductility without breaking. Hydrostatic testing at 1.5x plan weight guarantees leak-proof performance.
Microstructure investigation checks for delicate alpha case arrangement. Third-party reviews by SGS, BV, or TÜV are accessible upon ask, giving autonomous confirmation for your quality affirmation arrange.
Applications
Aerospace & Defense: Aircraft hydraulic lines and fuel systems benefit from Grade 9's high cycle fatigue strength. Its 4.48 g/cm³ density reduces airframe weight while withstanding vibration and pressure variances.
Chemical Processing: Grade 7 excels in chlor-alkali plants, handling hot concentrated brine where stainless steel fails. Pulp bleaching systems utilize our titanium alloy pipes for chlorine dioxide service.
Marine Engineering: Subsea umbilicals and heat exchangers leverage Grade 2's immunity to seawater crevice corrosion. Desalination plants operate maintenance-free for decades.
Medical Devices: Grade 23 ELI (Extra Low Interstitial) meets FDA biocompatibility standards for surgical implant fabrication and pharmaceutical processing equipment.

Packaging & Shipping
Each pipe bundle is wrapped in waterproof plastic film and secured with steel straps. Wooden cartons or plywood cases ensure against transportation affect for universal shipments. Pipe closes are capped with plastic plugs to anticipate contamination.
Containers are fumigated per ISPM 15 guidelines for phytosanitary compliance. We organize Dandy, CIF, or DDP terms based on your inclination. Documentation incorporates commercial receipt, pressing list, MTC, and certificate of origin.
Typical lead times: Stock orders transport inside 3-7 days. Standard generation completes in 15-25 days. Custom details require 25-40 days depending on complexity and amount.
FAQ
Q: Can the product be welded to stainless steel?
A: Direct welding is not recommended due to brittle intermetallic formation. Use explosion-bonded transition joints or mechanical fittings for dissimilar metal connections.
Q: What causes discoloration during welding?
A: Blue or gold tinting indicates oxygen contamination, forming brittle alpha case. Maintain argon back-purging at 15-20 CFH and use trailing shields to prevent embrittlement.
Q: How do I prevent galling during threading?
A: Apply anti-seize compounds like molybdenum disulfide or nickel-based lubricants. Machine threads slowly (20-30 RPM) with sharp carbide tools to minimize work hardening.
Q: Is Grade 5 suitable for seawater service?
A: Yes, but Grade 2 or 7 offers better cost-effectiveness. Grade 5 is preferred when you require higher strength alongside corrosion resistance, such as deep-sea structural components.
Q: What is the maximum bending radius?
A: Cold bending requires a minimum radius of 3x the outer diameter to avoid cracking. Hot bending at 600-800°C allows tighter radii but may require re-annealing.
