Quills Access fittings play a key role in the safe and efficient delivery of chemicals into the piping system. These joints are made of high-performance sealing materials that prevent leaks even at high pressures, ensuring maximum operational safety and efficiency.

One of the main features of the Quill Access pipe fitting is its built-in liquid injection pump. The system allows chemical liquids to be precisely injected into the pipeline through special valves and connecting pipes. Alternatively, it can easily extract the media inside the pipe into a sampling container, providing a universal solution for a variety of pipe processes.

chemical injection quill

Chemical injection components are an important tool for the oil and gas industry. Operators use these components to inject chemicals into high-pressure pipes that carry production fluids, seawater, and a variety of other media. This process has several purposes, such as improving the operational efficiency of the associated processing equipment, protecting the equipment and wellhead pipes, and extending the service life of the equipment.

Chemical injection tubes have been widely used in the global oil extraction and processing industry. In oil field production, chemical injection pump systems mainly inject methanol or ethylene glycol into the fluid upstream of the nozzle manifold. This action prevents the fluid from forming frozen hydrates due to a drop in pressure. At the same time, the reliability of the surface test system and the upper and lower pressure drop range of the nozzle are improved, so that the oil (gas) well can resume normal operation.

This ensures safety. In the process industry, we use chemical injection systems. This allows liquid chemicals to be precisely injected into the reinjected or injected liquid at either high or low pressure. There are many types of chemical agents that are injected into the solution, usually including methanol, ethylene glycol, preservatives, and deoxidizers. There are also drilling fluid additives (caustic soda and liquid polymers) and defoamer. Chemical injection pump systems can also be used to quantitatively deliver feedstock to high-pressure reactors.

The chemical fuel injection pump system consists of three parts: ultra-high pressure hydraulic, mechanical and driving air. The hydraulic section provides an ultra-high pressure source for the chemical injection system. The driving air section powers the entire system. The maximum working pressure of the chemical injection system is 1050bar. The high voltage circuit is equipped with filtering and overvoltage protection devices. With oil level and pressure display function. It also has the function of retaining pressure and discharging material. The driving air section powers the entire system. The maximum operating pressure of the driving air circuit is 10bar. The drive air circuit is equipped with filtering and overvoltage protection devices. With pressure display function. It also has a pressure regulation function.


Types of nozzles

Introduction to Types of Nozzles in Chemical Injection Quills

The chemical injection quill is equipped with four different types of nozzles, each designed for a specific function and purpose. Understanding these different nozzle types can help optimize your use in a variety of applications. Each nozzle type has its own unique advantages and applications, thus expanding the versatile use of chemical injection feather tubes in the oil and gas industry.

Parallel nozzles: As the name suggests, parallel nozzles are designed to be parallel to the direction of flow in the pipe. This is the ideal way to inject chemicals and immediately merge with the pipeline flow.

Vertical nozzles: As opposed to parallel nozzles, vertical nozzles are at right angles to the pipe flow. This allows for a more dispersed chemical injection, raising the pipe content of the mixture.

Open nozzle: This type of nozzle has no limiting structure at the end of the feather. The open nozzle allows chemicals to flow freely and unrestricted into the pipe, providing a large volume injection.

Sampling quill: The sampling pen is used to extract samples from the pipe instead of injecting chemicals into the pipe. This is essential for testing and quality control as it allows operators to monitor and evaluate the chemical composition in the pipeline.
