Definition - What does Containment Collar mean?
A containment collar is part of a protection system for liquid storage tankages such as containment sumps. Containment collars are factory bonded to the storage tank's wall and are available in double-wall and single-wall containment collar storage tank models.
Corrosionpedia explains Containment Collar
Containment sumps are made of high resistance polyethylene that can withstand harsh corrosive environments. Therefore, containment collars and other components of containment sumps and storage tanks should possess similar qualities.
To protect storage tanks from harsh corrosive environments, the containment collars are fitted to the body of the sump with the help of an EZ-Fit adhesive channel. Double-wall containment collars, when combined with CSI double-wall sumps will continuously monitor the entire containment area for leaks from tank top to grade providing secondary containment for spilled liquids.
Containment collars are available in two types:
- Flanged containment collars
- Vertical containment collars
