A reference standard

1, GB 228 metal tensile test method

2, GB 224 metal tube hydraulic experimental methods

3, GB 226 metal tube flattening experimental methods

4, GB/T3620.1 titanium and titanium alloy grades and chemical composition

GB/T3620.2 titanium and titanium alloys chemical composition and ingredients allowable deviation

Second, the technical requirements

1, and the chemical composition of titanium and titanium alloy sheet should be consistent with the provisions of the GB/T3620.1 the demand side reinspection, the chemical composition of the deviation should be allowed to meet the requirements of the GB/T3620.2.

2, pipe diameter tolerances shall comply with the form requirements.

3, the pipe wall thickness allowable deviation should not exceed its nominal wall thickness of ± 12.5% ​​for titanium welded pipe weld pipe wall thickness allowable deviation discomfort.

4, the length of the pipe should be consistent with the provisions of Table II.

5, pipe cut to length or double length should be cut lengths within definite length allows a deviation of +10 mm, double length should also be included in the amount of pipe cut incision, each should be 5 mm incision.
