Sample and Injection Quills

Sample and Injection Quills, also known as Sample or Injection Probes or Stingers, are generally constructed from an alloy such as 316/316L stainless steel. Materials to manufacture quills include bar stock, ASME pipe, flanges and fittings. Quill assemblies are manufactured to include valves and other process piping components.


  • CRN (Canadian Registration Number) for a wide variety of alloys
  • Full penetration welding for bar stock flanged quills
  • Full material traceability and NDE options

Application: Process sampling systems and chemical injection.
