Develop your tube weld test protocols
The calibration test, associated with a tube weld tester, allow to mesure the internal pressure of a tube subjected to the application of a crushing pressure exerted by the compressiometer
Why use a calibration kit ?
Each tube is defined by several parameters such as his fill rate, his diameter, his volume or his material. The variation of one of these parameters, for a similar crushing pressure, named “external”, cause a variation of the internal pressure of the tube, this latter revealing the real resistance of the tube weld. In addition, it was more pertinent to refer to this internal pressure.
It has to fix a restricted internal pressure meeting the most probable requirements, namely that the tube does not explode under normal use, and that it withstands transport constraints.
