Astm B861 Gr2 Gr7 Gr9 Gr12 Titanium Tube Thick 1.0mm 1.2mm Seamless Industry
Our Company
As a leading manufacturer of titanium products for over 16 years, Baoji Lihua has exported titanium tube to many countries, including the US, India and Korea etc. The quality of our products is widely recognized. So you should have confidence in our company.
1. Product Feature
Titanium tubes have the feature of light weight, high strength and superior mechanical properties. Titanium tubes are widely used in heat-exchange equipment, such as tube type heat-exchanger, coiled type heat-exchanger, coil heat-exchanger, condensator, evaporator and transmission pipeline. Many nuclear power industry ues titanium tubes as the unit standard tubes.
The seamless titanium tube/pipe is made by extrusion process, and the welded titanium pipe is welded from rolled titanium plate. Generally, the seamless titanium tube has a smaller wall thickness and a smaller caliber.
1. Seamless titanium tube/pipe has high hardness. The hardness HRC of titanium alloy (annealed state) is 32-38.
2. Seamless titanium tube/pipe has low elastic modulus. Titanium alloy (annealed) has an elastic modulus of 1.078 × 10 to
1.176 × 10 MPa, which is about half that of steel and stainless
steel.
Seamless titanium tube:
Diameter: O.D 6-108mm
Wall thickness: 0.5-8mm
Length: up to 15000mm
3. Excellent high and low temperature performance. At high temperatures, seamless titanium tubes can still maintain
good mechanical properties. Their heat resistance is much higher
than aluminum alloys, and their operating temperature range is
wide. At present, the working temperature of new heat-resistant
titanium alloys can reach 550-600 ℃ ; At low temperature, the
strength of titanium alloy is increased than that at normal
temperature, and it has good toughness. Low temperature titanium
alloy can still maintain good toughness at -253 ℃.
4. Seamless titanium tube has strong corrosion resistance. In the air below 550 ℃, titanium will quickly form a thin and
dense titanium oxide film. Therefore, its corrosion resistance is
better than that of most stainless steels in oxidizing media such
as air, sea water, nitric acid and sulfuric acid, and strong
alkalis.
