2. Key Features of the Retractable Chemical Injection Quill:
Versatile Design:
The quill is equipped with a variety of nozzle options to cater to different injection requirements, ensuring efficient delivery of chemical inhibitors directly into the pipeline system. This design allows for the adaptation to varying flow rates and viscosities of the injected chemical .
Robust Internal Assembly:
The internal components of the quill include a solid plug body, an injection nut, and an injection tube, all engineered to ensure durability and reliability. These components are connected to a Tee assembly that includes an NPT nipple, a valve, and an SWN flange to secure and stabilize the installation.
Flexible Process Connections:
The quill supports multiple connection sizes, including a 2″ flange, 2″ Flareweld access fitting, and 1″ Nipple to NPT ball valve, offering flexibility to match specific pipeline configurations and requirements.
High Operational Standards:
Designed to operate effectively within a temperature range of -20 ℃ to 150 ℃ and withstand pressures up to 6000 PSI, the quill is suitable for harsh environments and high-pressure applications typical in industrial settings.
3. Customization Options:
The EMT Injection System offers extensive customization through its varied Access Fitting Body options, such as:
- Material Options. Available in Carbon Steel (CS), 316 Stainless Steel (316SS), 316L Stainless Steel (316LSS), and DUPLEX Stainless Steel (DUPLEX SS).
- Connection Types. Options include a 2″ Welded configuration or a 2″ ANSI Flange, with additional specifications for pressure ratings and sealing types.
- Tee Sizes. Various Tee sizes are available ranging from 1/4″ NPT to 1″ NPT, as well as options for SWN Flange connections.
- Protective Cover Types. Choices range from no protective cover to covers equipped with or without holes, with bleed valves, and options for integrating pressure gauges.
4. Example Configuration:
For instance, an EMT-CIPA model with the specification 0F600#RF-2-1/CS includes a 2″ ANSI 600#RF Flange Access Fitting Body in Carbon Steel, a 1/2″ NPT(F) Tee, and a protective cover in Carbon Steel without holes. This demonstrates the modularity and adaptability of the system to meet specific operational needs and environmental conditions.
