Eddington Industries standard injection quills are designed to ensure a more uniform and rapid dispersal of injected chemicals into the center stream of a process pipeline. This prevents corrosive liquids from clinging to the side of the pipe.

Eddington Industries Injection quills are available in a variety of materials and pressure ranges.  Pressure and temperature ranges are dependent on the material of construction and vary from 150 and 3000 psi and 100 °F (37 °C) and 750 °F (400 °C).

Features of Injection Quills:

  • Type 316 Stainless Steel, Alloy 20, and Hastelloy C276 quills are suitable for high pressure, high temperature applications.
  • Simple to use ½”, ¾”, or 1” MNPT male process connection and ½”, ¾”, or 1” MNPT male chemical inlet connection.
  • The QC series of the Eddington injection quills come with a built-in check valve to prevent back flow of water or steam through the nozzle and into the chemical line.
  • The crack pressure (amount of psi required to open the check valve) on the QC series of injection quills is 20 psi.
  • For applications that do no require a check valve, the QB series of the Eddington injection quills come without a check valve.
  • All of the Eddington injection quills come with two machined flat surfaces on external portion of nozzle so a wrench can be used during installation.
  • The QC and QB injection quills come with the telltale V notch and witness mark to ensure proper nozzle alignment with process steam for proper dispersal of injected chemical.
  • Standard quill length is 2 3/4″ long but custom lengths up to 24″ are available. For additional lengths please add the quill length desired to the end of the Eddington part number (e.g. QCFM-316-050-18).
  • Made in the USA
