Grade 2 Titanium Tube for Aerospace/Medical Industry - China Suppliers & Factory, Customized Sizes Available
Product Description
Titanium Tubes are industrial tubular products manufactured from titanium or titanium alloys.
Performance Characteristics
Excellent Corrosion Resistance
Titanium forms a dense oxide film in various media, protecting it from corrosion. In seawater, neutral solutions, and reducing and oxidizing media, commercially pure titanium exhibits superior corrosion resistance compared to stainless steel. In acidic media, the corrosion rate of standard commercially pure titanium is significantly lower than that of stainless steel, aluminum and its alloys, and copper and its alloys.
High Strength and Low Density
Titanium has a density of approximately 4.5 g/cm³, only 60% that of steel, yet its strength is comparable to stainless steel. Titanium alloys possess strength far exceeding many alloy structural steels, enabling the production of lightweight components with high specific strength and stiffness.
Good High & Low-Temperature Performance
Titanium tubes have a wide operating temperature range. Titanium alloys can operate long-term at 450°C to 500°C. Furthermore, titanium alloys with extremely low interstitial element content retain good mechanical properties at cryogenic and ultra-low temperatures.
Good Thermal Conductivity & Weldability
Titanium's thermal conductivity is about 1/7 that of iron and 1/13 that of aluminum, making it an effective thermal insulation material. Titanium tubes can be welded using various methods, with welded joint strength reaching up to 90% of the base metal strength.
Non-magnetic
Titanium tubes are not magnetized in magnetic fields, making them suitable for magnetically sensitive applications.
Classification
By Material
Divided into pure titanium tubes and titanium alloy tubes. Common commercially pure titanium tube grades include TA1, TA2, TA3, etc. Titanium alloy tube grades include Ti-6Al-4V, etc.
By Manufacturing Process
Divided into seamless titanium tubes and welded titanium tubes. Seamless tubes are produced via processes like hot piercing, cold rolling, and cold drawing. Welded tubes are formed by rolling titanium plate into a tubular shape and then welding the seam.
Production Processes
Raw Material Processing
Titanium or titanium alloy raw materials are inspected, cut, and surface defects/impurities are removed.
Billet Production
Billets are made using processes like extrusion or casting. Extrusion involves forcing heated titanium alloy billets through a die. Casting involves pouring molten titanium alloy into molds to solidify.
Forming
Seamless Tubes
Typically formed via hot rolling, cold rolling, or cold drawing.
Welded Tubes
Formed by rolling titanium plate into a tube shape followed by welding.
Heat Treatment
Processes like solution treatment and aging are applied to enhance the tube's strength, toughness, and corrosion resistance.
Surface Treatment
Methods like mechanical polishing, chemical polishing, and sandblasting are used to improve surface quality, wear resistance, and corrosion resistance.
