1. Seamless titanium tube /pipe has high strength. Titanium alloy has high strength. Its tensile strength is 686-1176mpa, while its density is only about 60% of that of steel, so its specific strength is very high.
2. Seamless titanium tube has high hardness. The hardness HRC of titanium alloy (annealed state) is 32-38.
3. Seamless titanium tube has low elastic modulus. The elastic modulus of titanium alloy (annealed state) is 1.078 × 10-1.176 × 10MPa, about half of that of steel and stainless steel. Executive Standards: astmb337, astmb338, astmb338b861
Seamless titanium tube:
Diameter: o.d6-108mm
Wall thickness: 0.5-8mm
Length: up to 15000mm
4. Excellent high and low temperature performance. At high temperature, titanium alloy can still maintain good mechanical properties. Its heat resistance is higher than that of aluminum alloy, and its working temperature range is wide. At present, the working temperature of new heat-resistant titanium alloy can reach 550-600 ℃; At low temperature, the strength of titanium alloy is higher than that at normal temperature, and has good toughness. Low temperature titanium alloy can maintain good toughness at - 253 ℃.
5. Seamless titanium pipe has strong corrosion resistance. In the air below 550 ℃, the surface of titanium will quickly form a thin and dense titanium oxide film. Therefore, its corrosion resistance is better than that of most stainless steel in oxidizing media such as atmosphere, seawater, nitric acid and sulfuric acid and strong alkali. Seamless titanium pipe is made by extrusion process, and welded titanium pipe is made by welding after plate crimping. Generally, the wall thickness and diameter of seamless titanium pipe are relatively small
