The Jonas, Inc. Chemical Injection Quill, unlike other quills, has a tapered shape which is designed to reduce the effects of vortex shedding, thereby reducing the likelihood of erosion-corrosion, cavitation, and quill fatigue cracking.
In the past, chemical injection quills have not been much more than a piece of tubing extending into a pipe. Such design is prone to erosion-corrosion and cavitation in the piping after the quill due to vortex shedding and other problems. In addition, these quills and the piping just downstream are often not properly inspected. As a result, there have been cases of damage to the piping just after these quills.
Each Jonas, Inc. Chemical Injection Quill is custom designed for each application with considerations of vortex shedding, resonance, vibration, erosion, and strength of the attachment to the pipe, according to ASME rules.
