scope:
This part of ISO 25902 specifies a method for the eddy-current examination, hereafter referred to as the "examination", for detecting flaws in titanium seamless tubes and welded tubes, hereafter referred to as the "tubes".
Titanium tubes are now used as steam surface condensers in steam-power plants, anatomic-power plants and desalination plants. Therefore, the quality of titanium tubes is very important and this is why the eddy-current inspection method was established. This method also applies to titanium alloy tubes.
In this part of ISO 25902
- the minimum wall thickness is 0,3 mm,
- the rectangular groove and the drilled hole are permitted as reference standards,
- as the outside diameter of the titanium tube increases, the detected flaw also increases. The limit of the outside diameter of the titanium tube is 38,1 mm.
