TA2 titanium alloy tube is an industrial pure titanium product with titanium content ≥99.2%, strictly complying with international and domestic standards. Compared with TA1, it has higher strength while retaining the inherent advantages of pure titanium such as lightweight, corrosion resistance, good biocompatibility and excellent processability. It is available in seamless and welded types, with customizable specifications to meet the diverse needs of different industrial scenarios. Whether it is for corrosive medium transportation, heat exchange equipment or medical devices, TA2 titanium alloy tube can provide stable and reliable performance support.

The chemical composition of TA2 titanium alloy tube is strictly controlled to ensure product stability and performance. The specific components meet GB/T 3622-2007, ASTM B338 and other standards, with the following details:

Note: Medical-grade TA2 titanium tubes can be customized with stricter impurity control to meet ASTM F67 standard requirements.

TA2 titanium alloy tube has excellent mechanical properties, with high strength and good plasticity, suitable for various forming and processing. The specific parameters are as follows:

Note: The strength of cold-worked TA2 titanium tube can be increased to ≥600MPa, and the performance can be adjusted according to processing needs through annealing treatment.

TA2 titanium alloy tube adopts advanced production technology, focusing on solving problems such as difficult low-temperature piercing and titanium adhesion during processing, ensuring product quality and yield. The specific process is as follows:

High-purity Titanium Sponge → Vacuum Arc Remelting (VAR) → Titanium Ingot Heating (820-870℃) → Skew Rolling Piercing → Vacuum Annealing (550-680℃) → Straightening → Pickling (HF+HNO₃ mixed acid) → Cold Rolling → Degreasing → Secondary Vacuum Annealing → Straightening → Pickling → Finishing → Non-Destructive Testing → Packaging.

TA2 Titanium Strip/Plate → Pickling Cleaning → Roll Forming → TIG Welding (Argon Protection) → Weld Annealing → Sizing → Finishing → Non-Destructive Testing → Packaging.

Each batch of TA2 titanium alloy tubes undergoes strict multi-level inspection to ensure compliance with standards and stable performance:

• Chemical Composition Inspection: Spectral analysis to detect element content, ensuring no excessive impurities.
• Mechanical Properties Inspection: Tensile test and hardness test to ensure strength, plasticity and other indicators meet requirements.
• Non-Destructive Testing: Eddy current testing (surface defects), ultrasonic testing (internal defects), hydrostatic test (sealing performance).
• Dimensional & Surface Inspection: Check outer diameter, wall thickness, straightness and surface quality to ensure compliance with customer requirements.

1. Excellent Corrosion Resistance: TA2 titanium alloy forms a dense and stable TiO₂ passive film on the surface, which has excellent corrosion resistance in seawater, chlorides, dilute acids, alkalis and organic media, far superior to stainless steel. It is especially suitable for harsh corrosion environments such as marine engineering and chemical industry.
2. Balanced Strength & Plasticity: Compared with TA1, it has significantly improved strength while maintaining good plasticity, realizing the balance of performance and cost. It can be bent, stamped, welded and other processing, and is suitable for both structural parts and conveying pipelines.
3. Lightweight & High Specific Strength: With a density of only 4.51g/cm³, it is 60% of steel and 45% of copper. Its specific strength is superior to 304 stainless steel, which can significantly reduce equipment weight and reduce transportation and installation costs.
4. Good Biocompatibility: Non-toxic, non-magnetic and non-sensitizing, it has good affinity with human tissues and body fluids, and is suitable for medical devices such as oral implants and surgical instruments.
5. Excellent Processability: It has good formability and weldability. The welded seam performance is close to the base metal, and it can be processed by cold and hot processing. The production process is mature and the yield is high.
6. Long Service Life & Environmental Protection: It can be 100% recycled without environmental pollution. Under normal use conditions, the service life can reach 20-50 years, reducing maintenance and replacement costs.

As a versatile industrial pure titanium tube, TA2 is widely used in various industries, covering civil and high-end industrial fields, and is the bridge between cutting-edge performance and large-scale industrial application:

Corrosive medium conveying pipelines, chemical reaction kettle supporting pipelines, pickling equipment pipelines, chlor-alkali industry equipment pipelines, etc., suitable for conveying acetic acid, dilute sulfuric acid, chlorides and other media.

Seawater cooling pipelines, ballast water pipelines, seawater desalination equipment pipelines, offshore platform supporting pipelines, etc. It has excellent seawater corrosion resistance and can meet the requirements of high flow rate of modern ship pipelines.

Heat exchanger tubes, condenser tubes of thermal power plants and nuclear power plants, waste heat recovery equipment pipelines, solar water heater pipelines, etc., with good thermal conductivity and corrosion resistance.

Non-load-bearing or low-load-bearing implants, oral implant abutments, medical equipment supporting pipelines, etc., meeting medical hygiene standards and no interference with medical testing.

Food & Pharmaceutical Industry: Hygienic pipelines for juice, dairy products and liquid medicine conveying; High-end Consumer Goods: High-grade spectacle frames, golf club heads, high-end cookware; Aerospace Industry: Non-load-bearing parts such as aircraft engine nacelles and hydraulic system pipelines.

• Storage: Store in a dry, ventilated warehouse without corrosive gases, avoid moisture, rain and sun exposure; do not mix with strong acids, strong alkalis and heavy metals; stack neatly to avoid collision and scratch.
• Usage: Avoid long-term use in high-temperature environments (exceeding 350℃); use argon protection during welding to prevent oxidation; avoid excessive force during installation; clean the surface regularly to extend service life.
• Transportation: Wrap with plastic film and pack in wooden boxes to avoid collision and friction during transportation, and prevent rusting.
