Description
A Chemical Injection Quill is a device used in various industries, like oil and gas, for injecting chemicals into a system. It’s designed to deliver chemicals accurately at a specific point, helping control processes or prevent issues like corrosion in pipelines. These quills can be customized based on needs and are made from high-quality materials for reliable, long-lasting use.
Injection quills are used extensively across various sectors due to their ability to accurately and safely deliver chemicals into a system. In the oil and gas industry, they’re used to inject corrosion inhibitors into pipelines to reduce the rate of corrosion and extend the lifespan of the infrastructure. They are also applied in water treatment plants where they introduce disinfectants to eliminate harmful bacteria and other pathogens. In the chemical manufacturing industry, injection quills are used to add precise amounts of reagents during different stages of production, ensuring product quality and safety. Lastly, in power plants, they help in the accurate injection of chemicals for controlling pH, preventing scaling, and reducing the potential for corrosion in boiler systems.

Installation Method
Follow these steps to install the chemical injection quill:
- Start by wrapping the sealing strip on the threaded end of the dropper. Attach this to the NPT fitting of the injection nut and tighten.
- Next, place the main seal packing on the plug’s screw with its larger end facing the plug’s center. Connect this to the other thread of the injection nut, tighten it, and secure the set screw.
- Temporarily fix the flange seat of the equipment to the pipe’s mounting flange, but do not tighten it yet.
- Securely fasten the assembled stopper injection assembly to the flange seat.
- Now, loosen the connection to the mounting flange. Remove the entire device and determine the orientation of the bevel of the injection cannula. Adjust the orientation so that the spray sleeve’s inclination is opposite to the medium’s flow direction, opposite of the nozzle. You can measure or visually inspect the angle between the tee port or tee flange adapter and the desired position.
- Unscrew the fitting body from the plug injection assemblies by rotating it counterclockwise at a certain angle. Then, loosen the injection nut’s fastening screw and screw it up.
- If the injection body is in a tee port shape, wrap a sealing strip around the two ends of the NPT tube. Connect one end to the T-type side opening on the flange pedestal and the other to the valve end. Screw these up to secure them.
