Titanium tube

Titanium tube has light weight, high strength and superior mechanical properties. It is widely used in heat exchange equipment, such as tubular heat exchanger, coil heat exchanger, serpentine heat exchanger, condenser, evaporator and pipeline. Many nuclear power industry take titanium tube as its standard tube.

According to the different use requirements and performance, titanium pipes are subject to two national standards: GB / t3624-2010, GB / t3625-2007, ASTM b337 338

Supply brand: TA0, TA1, TA2, ta9, TA10, bt1-00, bt1-0, GR1, Gr2

4. Grade and chemical composition of titanium and titanium alloys (GB / t3620.1)

5. GB / t3620.2 chemical composition and allowable deviation of titanium and titanium alloy products

II. Technical requirements

1. The chemical composition of titanium and titanium alloy pipes shall comply with the provisions of GB / t3620.1. When the demander rechecks, the allowable deviation of chemical composition of Mingkun titanium industry shall comply with the provisions of GB / t3620.2.

2. The allowable deviation of the outer diameter of the pipe shall comply with the provisions in Table 1.

3. The allowable deviation of pipe wall thickness should not exceed ± 12.5% of its nominal wall thickness. The allowable deviation of pipe wall thickness is not applicable to the weld of titanium welded pipe.

4. The length of the pipe should meet the requirements of Table 2.

5. The fixed length or double length of the pipe should be within the range of its variable length. The allowable deviation of the fixed length is + 10 mm. The double length should also be included in the amount of cut when the pipe is cut. The amount of each cut should be 5 mm.
