Quality management


Pipelife Gas-Stop™ units are safety products on which the highest demands are placed with regard to service life and operational reliability. Accordingly these products are subjected to extensive quality tests. The testing programs concern both the individual components as well as the end products. One of the most important testing steps is the verification of the function before shipment. On a computer-controlled test bench the shut-off flow and tightness of every individual Pipelife Gas-Stop™ unit are measured and recorded with the latest measuring equipment.


The positive test result is documented on the product through the issue of a consecutive serial number. This serial number is also assigned to all test results of the individual components, so that continuous traceability is provided.


In order to ensure the certainty of the function in normal operation as well as when closing in practical operating situations, Pipelife Gas-Stop™ units are also continuously tested on a natural gas test bench constructed specifically for this purpose. This test bench is also used to determine influences (e.g. pulses) from the regulating devices and consumer appliances situated upstream and/or downstream of the Pipelife Gas-Stop™ unit or also from pipe network sections and to take these into account accordingly in the product characteristics. Of course, practically relevant customer-specific tests can also be carried out.
