This layout will improve the overall operating performance of the piping system. For optimum performance, the Series 4400 expansion joints should be installed hori- zontally to the shaft. Vertical and perpendicular installations are also acceptable, as these expansion joints will accept axial, lateral and angular movements as well as vibration. Note: For maximum vibration transmission reduction, the pipe section beyond the PTFE expansion joints must be anchored or sufficiently rigid. Reduces System Stress and Strain. Rigid attachment of piping to critical or mechanical equipment can produce excessive loading. Thermal or mechanically created strain/stress/shock are cushioned and absorbed with the installation of a flexible PROCO Series 4400 PTFE Expansion Joint. The Series 4400 expansion joint adds a flexible component to the system that automatically self-corrects for misalignment created by structural movements caused by settling, pipe expan- sion or ground shifts. � PROCO PRODUCTS, INC.
