fab shop could use vacuum testing.

the position of RT source is tube inside and
film specially manufacted is locatited in tube edge.

The least strigent requireed an Bubble Test.
Though MT & Liquid Penetrant is widely used.

It´s necessary to know some details, like:
- Use: requeriments are different depending of the use. Power plant pipng has higer requeriments that water-treatment plant (pressures, tempratures......)
- kind of joint: For groove welds you only can aplly RT and UT testing (volumetrics). If don´t need a complete penetration, you can use MT or PT (surface).
- Material: In non ferrous material (aluminium or PE))you can not carry out MT testing. I imagine tube is manufactured in steel (maybe ASTM A-106)
- Thickness: With 0,32 inch. or less you can not use UT testing.
- Leak testing is indicated to asure watertightness
If that tube hasn´t high requeriments, PT is the best.
