Long-term performance of infrared welded PVDF and PP Piping systems
Studies indicate that the long-term weld factor for PVDF-IR and HS welds can be set above 0.8. They also emphasize the importance of effective time-dependent behavior for the service life and safety of the weld connection. Infrared heating element butt welding has proven to be a technologically superior method, resulting in improved weld seam quality and has been successfully employed for about ten years for both PVDF and PP pipes.
