Chemical
Injection Quills

Koflo Chemical Injection Quills are used to introduce medium to highly corrosive chemicals into a pipeline without damage to the side port or pipe wall at the point of injection. Chemical injection quills ensure that chemicals are evenly dispersed into the center of the pipeline, which prevents channeling of the chemical down the pipe wall. The body and stinger are both constructed of chemical resistant plastics or alloys (PVC, Kynar, 316 SS, or Hastelloy C-276). Injection quills with 3” and 5” long stingers are available from stock. All injection quills come with 1/2" FNPT x MNPT connections for ease of installation.

Precision-Engineered Components

Machined housings ensure reliable and even chemical dispersion within the center of the pipeline. During the manufacturing process, all quills are individually tested to Koflo's high standards and are guaranteed to be leak-free. Each unit comes complete with an integral removable spring-loaded ball check to prevent flow of the injected chemical into the main flow when the system is shut down.
