1. According to the connection form

Welding fittings (butt welding, socket welding): suitable for systems with high pressure and high sealing requirements (such as chemical pipelines);

Threaded fittings: used for small equipment or low-pressure scenarios (such as laboratory instruments);

Flange connection fittings: Used in combination with titanium flanges for easy disassembly and maintenance (such as ocean engineering pipelines).

2. By Function Type

Straight through fittings: conventional connectors such as elbows, tees, reducers, etc;

Special fittings: expansion joints, corrugated pipes (suitable for thermal expansion and contraction or vibration environments).

3. Classified by Material

Pure titanium fittings (TA1/TA2): excellent corrosion resistance, suitable for chemical and medical equipment;

Titanium alloy fittings (TC4, Ti-3Al-2.5V): high strength, high temperature resistance, used in the aerospace and nuclear energy fields.

TA1/TA2: Excellent corrosion resistance, good plasticity, and high biocompatibility;

TC4: High strength, fatigue resistance, and optimal comprehensive performance;

Ti-3Al-2.5V: High temperature creep resistance, stress corrosion resistance;

Gr5/Gr7: International standard grades, corresponding to TC4 and corrosion-resistant titanium alloys.

1. Forming process

Extrusion molding: preparing seamless titanium tube blanks through hot extrusion, with uniform grain size;

Welding Forming: Automatic argon arc welding of rolled titanium plate, used for large-diameter pipe fittings.

2. Processing procedure

Cold/hot processing: rolling, drawing to control dimensional accuracy;

Heat treatment: Annealing eliminates internal stress, solid solution strengthening enhances performance;

Surface treatment: Acid washing to remove oxide layer, electrolytic polishing to enhance corrosion resistance.

3. Quality control

Non destructive testing (X-ray inspection, ultrasonic testing) ensures the quality of welds;

Pressure testing (1.5 times working pressure holding) to verify sealing reliability.

Lightweight: with a density of only 60% of steel, reducing system load;

Corrosion resistance: resistant to seawater, strong acids, chloride ions and other media, with a service life of over 20 years;

High temperature stability: Some alloy fittings can work for a long time at temperatures above 300 ° C;

Biological inertness: non-toxic, non-magnetic, suitable for human implantable devices;

Fatigue resistance: Suitable for vibration and cyclic load environments (such as aircraft engine pipelines).

Chemical energy: sulfuric acid/hydrochloric acid transport pipelines, nuclear reactor cooling systems;

Ocean engineering: seawater desalination equipment, deep-sea oil and gas pipelines;

Aerospace: Lightweight fuel pipelines, hydraulic systems, and high pressure resistance;

Food and pharmaceuticals: sterile conveying pipelines, fermentation tank connectors.
