Field Erected Polypropylene Tank

FIELD ERECTED POLYPROPYLENE TANKPKG Equipment Inc. replaced a bulging and brittle rotationally molded tank with a custom fabricated polypropylene tank that was shipped to the job site in pieces that would fit through a 5′ x 6′ opening. The tank was located in the basement of the Pennsylvania American Water Company’s water treatment plant in Hummelstown, PA. The largest opening to the basement was a 5′ x 6′ hatch in the first floor of the building, but the tank needed to be 142″ Ø x 101″ high.

In order to avoid any demolition work that would be required to get the tank installed in one piece, PKG Equipment assembled and extrusion welded the tank on site. The tank was fabricated from ½” thick copolymer polypropylene and was supported by epoxy coated steel girth bands. Field erecting this tank saved the customer money and greatly reduced their downtime.
