Chemical Injection Quills



Chemical injection quills play a crucial role in various industries, especially the oil and gas sector. These mechanical devices act as an interface between the chemical feed line and the processing pipeline, ensuring the safe and efficient injection of chemicals to achieve the desired chemical reaction.

Introduction to Chemical Injection Quill

A chemical injection quill is a specialized piece of equipment designed for injecting chemicals into pipelines and vessels. It ensures that the chemicals are dispersed evenly within the processing pipeline, thus enhancing the efficiency of the feed system. The quills are available in various configurations, connections, and fittings to cater to different application requirements.

Types of Chemical Injection Quills

Flange Connection Chemical Injector: This type of chemical injection quill features a flange connection, which is ideal for high-pressure applications. The injector is mounted on the pipeline through a 2” flange, ensuring a secure and leak-free connection.

Welded Injection Chemical Injector: This injector features a 1” NPT welded base or 2” flare weld access fitting for secure mounting on the processing pipeline. The welded connection ensures a strong and durable bond, suitable for high-pressure and high-temperature applications.

Retractable Chemical Injector: Retractable chemical injectors are designed for easy insertion and removal from the processing pipeline without interrupting the flow. They have a pressure rating of 2000 Psi and are suitable for applications where routine maintenance or chemical changeovers are necessary.
