News from Quality Control
PT&P’s QC Manager, has lead several testing efforts including three at cryogenic temperatures. Two of these tested coils in springs, the other tested an anchor for cryogenic pipelines. Tests on aluminum travel stops proved successful and these are a new PT&P standard. Other new standard procedures cover bonding processes.
The picture at left shows PT&P’s QC Manager as he is preparing to test the pressure capability of a 4″-150 lb. rated metal expansion joint unit. The unit is sealed and gauged as air is introduced through a fitting on the top blind flange. As a pump supplies air, the gauges indicate how much pressure the unit is experiencing.
