An injection quill is a device used in industrial processes to introduce a controlled amount of a chemical or fluid into a system. It typically consists of a tube or pipe with multiple holes or nozzles to evenly distribute the injected substance. Injection quills are commonly used in water treatment, chemical processing, and other industrial applications where precise dosing of chemicals is required. They are designed to prevent localized corrosion or damage by evenly distributing the injected substance into the main process flow. Injection quills come in various materials such as stainless steel, PVC, or PTFE, to suit different chemical compatibilities. Additionally, they can be customized with different lengths, nozzle sizes, and configurations to meet specific process requirements. Proper installation and maintenance of injection quills are important to ensure accurate and reliable chemical dosing within the system.
Injection Quills improve injection and diffusion and allow for injecting corrosive chemicals into a pipeline without damaging the pipe or threaded port at the injection point. By injecting into the center stream of the pipe, the turbulent, higher pipe velocity improves chemical dispersion and results in a homogenous chemical mix. Many construction materials available including PVC, Kynar, Teflon, CPVC, 316L Stainless Steel, Hastelloy C-276, Titanium
Our Fixed Injection Quills, and machined housings, ensure reliable and even chemical dispersion at the pipeline’s center. Throughout the manufacturing process, we individually test all quills to meet high standards and ensure they are leak-free. Each unit contains a built-in, removable spring-loaded ball check that stops the injected chemical from entering the main flow when the system is switched off.
Industrial processes and chemical dosing systems utilize Fixed injection quills as devices. Their purpose is to introduce an additive, such as a liquid chemical or solution. This is introduced into a pipeline or process stream with a controlled and precise dosage. The quills typically consist of a tubular housing with a connection to the main pipeline. Also, the process stream and a separate injection point where the additive is introduced. This allows for controlled and accurate distribution of the additive throughout the system. This ensures uniform mixing and desired chemical reactions. They also find applications in various industries, including water treatment, chemical processing, and oil and gas.
Specific Point of Entry
Moreover, Fixed injection quills aim to avoid direct contact between the injected additive and the main process fluid or pipeline by introducing the substance at a specific point within the pipeline or process stream. This would be away from turbulence or high-velocity flow areas.
The quills also assist in preserving the integrity of the injected additive. In addition, by avoiding direct contact with the main process fluid. The quill protects the additive from potential contamination or degradation, which could negatively impact its effectiveness or stability.
Purpose
Another purpose of quills is to facilitate easy maintenance and replacement of the injecting components. You can detach the quill from the pipeline or process stream. It allows for convenient access and replacement of the injecting mechanism without interrupting the entire system’s operation.
Overall, the primary purpose of injection quills is to ensure the accurate, controlled, and safe introduction of additives. This introduction is into pipelines or process streams, while also protecting the integrity of the injected substance and facilitating ease of maintenance.
In addition to their primary purpose, injection quills offer a few other benefits:
Improved Mixing
Fixed Injection quills promote better mixing of the additive with the main process fluid. Introducing the additive at a specific point and with a precise dosage enhances the overall dispersion. It also enhances the distribution of the injected substance, resulting in more uniform and efficient mixing.
Reduced Equipment Corrosion
Many people use certain additives, like corrosion inhibitors, to shield pipelines or equipment from corrosion. The quills guarantee an even distribution of these additives. It is also for effectively dispersed throughout the system. In turn, it is reducing the risk of corrosion and extending the equipment’s lifespan.
Increased Safety
Quills help minimize the potential hazards associated with injecting chemicals or additives into process streams. By providing a designated injection point and ensuring proper flow conditions. This minimizes the likelihood of leaks. They also minimize spills, or accidental exposure to the additive, enhancing safety for operators and the environment.
Enhanced Control and Monitoring
Furthermore, various types of injection quills are available to integrate with monitoring and control systems. This allows for real-time monitoring of the injection process and precise adjustment of injection rates. It also allows automated control over the additive dosage, offering greater control and accuracy in the treatment or enhancement of the main process fluid.
By serving these additional purposes, Fixed injection quills contribute to efficient and safe industrial processes, ensuring optimal performance and reliability.
Simple to use ½”, ¾”, or 1” MNPT male process connection and ½”, ¾”, or 1” MNPT male chemical inlet connection.
The quills come with an optional built-in check valve to prevent the backflow of chemicals through the nozzle and into the chemical line.
The crack pressure (amount of psi required to open the check valve) on the injection quills is 10 psi.
For applications that do not require a check valve, the injection quills default without a check valve.
The injection quills come with the V notch and dispersion holes to ensure proper nozzle alignment with process chemicals for proper dispersal of injected chemicals.
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.
