Supply grade: R60702 R60704 Zr-1 Zr-3 Zr-5 R60705
The production standard takes the national standard as an example
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/T13747 zirconium and zirconium alloy grades and chemical composition
Two technical requirements
1 chemical composition of zirconium and zirconium alloy tubes shall comply with the provisions of GB/T13747, when the re inspection,
2 the allowable deviation of pipe diameter and wall thickness shall be in accordance with table 1.
4 the length of the pipe shall be in accordance with table two.
5 the length of the pipe or the length of the length should be within the range of its length, the length of the allowable deviation of the length of +10mm, the length of the length of the pipe should be included in the cut, the amount of each incision should be 5mm. 　
Table 1 allowable deviation of tubes for heat exchangers
