1. Classified by structure and alloy type

Industrial pure titanium tubes: TA1 and TA2 grades, focusing on corrosion resistance and processability, used in chemical heat exchangers and electroplated anodes;

Titanium alloy tube:

α+β alloy tube: such as TC4, with excellent comprehensive performance, suitable for aerospace structural components;

Corrosion resistant alloy tube: such as TA10, resistant to crevice corrosion, used in seawater desalination equipment.

2. Classify by processing form

Seamless titanium tube: formed by extrusion, oblique rolling or cold drawing, with uniform wall thickness, suitable for high-pressure scenarios;

Welded titanium tube: made of rolled plate welding, low cost, used for low-pressure transportation.

Domestic brand: TA2 TC4、 TA9, Gr23.

International grades: Gr2, Gr5, Gr7, etc.

1. Melting: Vacuum consumable arc furnace or electron beam melting is used to ensure uniform composition and impurity content<0.1%;

2. Molding process:

Extrusion molding: 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 treatment: 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: Non toxic, non-magnetic, in compliance with ISO 5832 standard.
