The purpose of Injection quills is to introduce corrosive chemicals (medium to highly corrosive) into a pipeline without damaging the pipe wall or the side port at the exact point of injection. Chemical injection quills ensure that there is an even dispersion of chemicals into the pipeline's center, which avoids channeling down the pipe wall of the chemical. Both the stinger and the body are constructed of materials that are chemical resistant alloys or plastics (Kynar, 316 SS, Hastelloy C-276 or PVC). Each injection quill unit of Crystal Industrial comes in total with an integral removable ball check with spring loaded, to avoid flow of
the injected chemical passing into the main flow when the system is shut down.
In the past, chemical injection quills have been little more than a piece of tube extending into a pipe. This design is vulnerable to erosion-corrosion and cavitation in the piping due to vortex shedding and other hazards. Moreover, often these quills and the piping just downstream are not properly inspected. Due to which there have been numerous cases of damage to the piping just after these quills.
Crystal's chemical Injection Quills in UAE have a tapered shape which reduces the effects of vortex shedding, thus vastly reducing the likelihood of erosion-corrosion, cavitation, and quill fatigue cracking.
Each quill is custom designed for a specific application keeping in mind the vortex shedding, erosion, vibration, resonance and strength of the attachment to the pipe, according to ASME rules. The quill can be supplied with one or two root valves.
Crystal Industrial's, Chemical Injection Quills in UAE are employed for the introduction of medium to highly corrosive chemicals into pipelines without damaging the side port or the pipe wall at the point of injection.
Chemical injection quills ensure even dispersion of chemicals into the center of the pipeline, thus preventing channeling of the chemicals down the pipe walls.
Both the body and stinger of Crystal's injection quills in in UAE are constructed of chemical resistant plastics or alloys (PVC, Kynar, 316 SS, or Hastelloy C-276).
Each injection quill unit of Crystal 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.
Crystal's injection quills in in UAE come with stinger lengths of 3” and 5” are available from stock. All injection quills come standard with FNPT x MNPT connections for convenient installation.
