Pre-Insulated Foam System for Above Ground Applications
This above ground DEF piping consists of a HDPE carrier pipe insulated encased in a 300˚F polyisocyanurate foam that has a 25/50 Flame/Smoke rating. This makes this piping system suitable for indoor & outdoor service. The spiral seam jacket made of aluminum, galvanized or stainless steel is watertight. Systems are supplied in 20’ lengths and can be supported from the outside with maximum supports spans. It also can have an optional 1” tube for heat trace capabilities.
