Fusible PVC pipe is extruded from a specific formulation of PVC resin, which
allows the joints to be butt fused together using UGSI’s fusion process. Industry
standard butt fusion equipment is used with some minor modifications. The
resin/compound meets the PVC formulation in PPI Technical Report #2. With the
proprietary formulation, the fused joint strength is (minimum 95%) as strong as
the pipe wall. The fusible pipe is made in DIPS and IPS OD series, as well as
schedule and sewer sizes. The Fusible C-900 ®, Fusible C-905®, and FPVC
pipes are NSF 61 certified for potable water.
• AWWA C900 and C905 PVC pipe
• Corrosion resistant, abrasion resistant, high “C” factor at 150
• Fully restrained joint - Fusible PVC joints allow long lengths of pipe to be
used for HDD, pipe bursting and sliplining applications.
• NSF 61 certified for potable water
• Use standard fittings and service saddles
• Higher strength enables longer pulls and larger inside diameters
• Fusion time for joint is 1.5 to 2 minutes per diameter inch
• PVC fusion technicians need to be trained and qualified by UGSI.
Qualification only lasts one year.
• PVC is impacted by cyclic (fatigue) pressure loadings, which are typically
experienced in a force main application.
• As a stiff, strong thermoplastic, PVC has specific guidelines for bending
radius

Fusible PVC is extruded with a unique patent pending formulation that meets
PPI TR-2 range of composition of qualified PVC ingredients. Meets ASTM cell
classification 12454.
