Why ATS FXP™ Duct? Corrosion Resistance

All ATS FXP™ duct assemblies, by virtue of ATS’ innovative joining systems, have a continuous liner. This allows ATS to provide unparalleled corrosion resistance, since there are no weak points in ATS’ system, unlike competitive products.
ATS delivers trouble-free joint connections in several forms: i) ATS H-Collar, ii) ATS Slip Collar, iii) ATS ISO Flange, and iv) Van Stone Flange.

The ATS ChemBond™ allows contractors to install and modify ducts efficiently and without external wraps (even bonding directly to PPs, PVC, SS and Regular FRP) and maintains ATS’ high standard of corrosion resistance.
