Radolid® Protection Caps
DuoCon Centralizers are used to support and space a section of pipe inside a
secondary pipe on dual containment systems. These plastic centralizers can be
used on all types of pipe including fiberglass, PVC, polyethylene and steel.
APS centralizers are manufactured from injection molded, high density
polyethylene. Centralizers are also called spacers or spiders.
DuoCon Centralizers are lightweight, economical, and easy to install, requiring
only a screwdriver. We recommend installation every 800mm to 1,2 meters. Other
benefits of polyethylene include high impact strength and abrasion resistance.
The low friction of polyethylene facilitates easy installation when sliding the
central pipe. Molded into the inner surface are grooves which prevent slippage
and cold flow of coated pipe.
The APS DuoCon Centralizer has excellent dielectric resistance and low moisture
absorption which allows it to be used as an insulator for cathodic protection.
Sizes are available from 50mm to 300mm with a standard runner height of 25mm.
Extensions of as much as 50mm can be added optionally. Centralizers 350mm and above
are available in multi-segments. Corrosion resistant polyethylene materials
designed for dual containment systems. Available in sizes from 25mm to 1,2 meters.
