Installation Instructions for Hot, Cold and USDA Piping Systems The Zeston PVC/Perma-Weld® pipe jacketing system consists of Zeston PVC fitting covers, Zeston PVC jacketing (20 and 30 mil [0.5 and 0.8 mm] material only) and Zeston Perma-Weld solvent welding adhesive.
The Zeston/Perma-Weld protective jacketing system meets USDA requirements for piping systems in meat and poultry processing facilities. It also meets FDA standards for other food processing, beverage and pharmaceutical facilities. In these and related applications, the Zeston PVC/Perma-Weld system resists contaminant infiltration and withstands repeated washdowns while providing a clean, finished appearance over bare or insulated pipe.
Qualifications for Use
Install the appropriate Hi-Lo® Temp fiber glass insert by wrapping it completely around the pipe fitting without overly compressing it or leaving any voids. Ensure that the insulation insert covers all exposed surfaces. The Zeston PVC fitting cover should then be installed over the pipe fitting and fiber glass insert by securing the throat using either serrated tacks, Perma-Weld adhesive or Zeston Z-Tape.
The following sequence describes the installation of Zeston PVC jacketing and fitting covers with Perma-Weld solvent welding adhesive.
1. Position the Zeston PVC fitting cover over the insulated fitting.
