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.
Description
Strengths of kit:
The use of this Kit is a revelant prerequisite for setting up a test (protocol validation, creation of abacus, observation of physical phenomena, etc.) beacause it makes it possible to correlate the compression tube value with its internal pressure
ACRN can provide with the delivery of the system, an abacus validated during these years of experience.
Operation
You just have to open the valve to fill the water pipe. During the external effort, a pressure balance is then created between the water and the product, pressure reported at the level of the manometer, protected by a water membrane during compression.
Benefits
Establishment of a reliable weld resistance test protocol according to transport requirements
Adaptable to all types of samples
Adapted to the production envrionment / Robust
Many different pressers to reach the target internal pressure
