Main application areas

1. Aerospace

Fuel pipeline systems and structural components used in aircraft and spacecraft, capable of withstanding extreme temperature and pressure conditions.

Typical scenarios: fuel delivery, hydraulic system branch connections.

2. Ocean Engineering

Applied to seawater desalination pipelines, ship ballast water systems, subsea pipelines, etc., it has excellent resistance to seawater corrosion.

Case: Deepwater pipeline interface for offshore platforms.

3. Chemical/Petrochemical

Pipeline connections for handling corrosive media such as sulfur and chlorine, such as hydrochloric acid transportation and chlorine gas distribution systems.

Advantages: Reduce the risk of corrosion and leakage, and extend the service life of equipment.

4. Medical equipment

Used for pharmaceutical purified water systems, surgical instruments, and implant manufacturing, relying on its biocompatibility.

5. Nuclear power/new energy

Branch of nuclear reactor coolant pipelines and lithium battery electrolyte delivery system, suitable for high temperature and high pressure environments.

6. Nonferrous metallurgy

Magnesium, potassium and other metals are used for transporting corrosive media in smelting, replacing traditional materials to improve equipment life.

Case: Titanium tee joint and circulating water tank connection in magnesium smelting.

Key points and precautions for use

1. Welding process

Operation requirements: Use flux cored wire CO ₂ gas shielded welding, adjust the welding gun angle and swing amplitude during welding to ensure uniform weld seam.

Key steps: Drilling the main pipe and processing the saddle shaped groove of the branch pipe to avoid welding defects in the empty welding area.

2. Material selection

Select the type of titanium material based on the characteristics of the medium:

TA1/TA2: Suitable for general corrosive environments (such as chemical and marine).

TC4: High intensity scenarios (such as aerospace, nuclear power).

3. Design and Installation

Equal diameter tee vs reduced diameter tee: Choose according to fluid distribution requirements. Equal diameter tee (T-shaped) is suitable for uniform diversion, while reduced diameter tee (Y-shaped) is used for variable diameter diversion.

Inner wall treatment: Keep smooth to reduce fluid resistance and avoid impurity accumulation.

4. Maintenance and Inspection

Regularly inspect the corrosion of welds and connections, especially in high-pressure or high erosion environments (such as chemical and nuclear power).

Recommendation for replacement cycle: The service life in marine environments should be greater than 20 years, and the inspection interval should be shortened in high corrosion scenarios. ‌

summarize：Through the above application and usage standards, titanium tees can achieve efficient, safe, and durable fluid control requirements in multiple fields.
