A reference standard
1. GB 228 Metal tensile test method
2. GB 224 metal pipe hydraulic test method
3. GB 226 metal tube flattening test method
4. GB/T3620.1 titanium and titanium alloy grades and chemical composition
5. GB/T3620.2 Titanium and titanium alloy processed products chemical composition and composition tolerance
Two technical requirements
1. The chemical composition of titanium and titanium alloy pipes shall comply with the provisions of GB/T3620.1. When the buyer retests, the allowable deviation of the chemical composition 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 the pipe wall thickness should not exceed ±12.5% of its nominal wall thickness. The allowable deviation of the pipe wall thickness does not apply to the weld of the titanium welded pipe.
4. The length of the pipe shall comply with the requirements in Table 2.
5. The length of the fixed length or double length of the pipe should be within its indefinite length. The allowable deviation of the fixed length is +10mm. The length of the double length should also be included in the cut amount when the pipe is cut. Each cut should be 5mm.
