1. Classify by material
Industrial pure titanium tubes: TA1 and TA2 grades, known for their corrosion resistance and processability, suitable for chemical heat exchangers and electroplated anodes;
Titanium alloy tube:
α+β alloy tube: such as TC4, with excellent comprehensive performance, used for aviation engine components;
Corrosion resistant alloy tube: such as TA10, resistant to crevice corrosion, suitable for seawater desalination equipment.
2. Classified by processing technology
Seamless titanium tube: formed by hot extrusion or cold rolling, with uniform wall thickness, used in high-pressure scenarios;
Welded titanium tube: using coil welding technology, low cost, suitable for low-pressure medium transportation.
Domestic grades: TA2, TC4, TA9, Gr23;
International grades: Gr2, Gr5, Gr7, TC4 ELI.
1. Melting: Vacuum consumable arc furnace or electron beam melting is used to ensure impurity content<0.1%;
2. Molding process:
Hot extrusion: heated to 800-950 ℃, extruded through a mold to form a blank tube;
Cold rolling/cold drawing: precision machining to target size at room temperature, surface roughness Ra ≤ 0.4 μ m;
3. Welding process: argon arc welding or laser welding, with a weld strength of over 90% of the base metal;
4. Surface treatment: acid washing, sandblasting or anodizing to enhance corrosion resistance and aesthetics.
High strength and lightweight: TC4 titanium tube has a tensile strength of 895-1100MPa and a density of only 60% of steel;
Corrosion resistance: It has better corrosion resistance to seawater and chlor alkali media than stainless steel, and its service life is increased by 3-5 times;
Temperature adaptability: TA7 titanium tubes maintain toughness at -253 ℃, while TC11 alloy tubes can be used for long-term high temperatures up to 600 ℃;
Biocompatibility: Compliant with ISO 5832 standard, non-toxic, non-magnetic, suitable for human implantation scenarios.
Aerospace: engine compressor components, fuel delivery pipelines;
Chemical Ocean: seawater desalination equipment, chlor alkali reactors;
Energy industry: cooling pipes for nuclear power plants, bipolar plates for hydrogen fuel cells;
