Injection Quills for Controlled Chemical Dosing
Globe United supplies injection quills for introducing treatment chemicals into process pipelines. Correct insertion and discharge arrangement can improve mixing and help reduce excessive chemical concentration near the pipe wall. Applications include corrosion inhibitor dosing, water treatment chemicals, boiler and cooling water treatment, and other industrial chemical injection duties.
Fixed and Retractable Injection Quills
Fixed injection quills can be considered where removal is performed during a planned shutdown. Retractable designs can be reviewed where the operating procedure requires insertion or withdrawal using the selected isolation and retrieval arrangement. The final design must match the process pressure, temperature, fluid, material compatibility and site procedure.
Information Required for Selection
- Pipe size, schedule and material
- Process fluid, pressure and temperature
- Injection chemical and dosing rate
- Injection pressure and connection size
- Required insertion length and orientation
- Quill, flange and nozzle materials
- Fixed or retractable arrangement
- Testing and documentation requirements
Supply for Oman and Malaysia
Globe United supports injection quill enquiries for Oman, Malaysia, the UAE, Saudi Arabia and other export markets from its UAE engineering and supply base. Customers can submit the complete process and chemical data for technical review before quotation.
Frequently Asked Questions
Why is an injection quill used instead of injecting at the pipe wall?
A correctly selected quill introduces the chemical into the flowing stream at a defined location, supporting distribution and reducing concentrated exposure at the connection point.
What materials can be reviewed?
Material selection depends on the process fluid, injected chemical, pressure and temperature. Stainless steels and corrosion-resistant alloys can be reviewed against the submitted specification.
