PTFE, PVDF, PP, PFA and other materials used for chemical injection quills (manufactured in India) when used with corrosive fluids

PTFE, PVDF, PFA, PP, PVC, and other materials could also be used, depending on the type of corrosive fluid and the process. They are chosen based on how well they resist chemicals, how well they handle heat and cold, and how strong they are.

Advantages of PTFE bodied chemical injection quills manufactured in India

PTFE, also known as Teflon, is a type of plastic that is highly resistant to chemical reactions and can be used in chemical injection quills for corrosive fluids. The advantages of PTFE include:

  • Chemical resistance: PTFE is highly resistant to a wide range of chemicals, including acids, bases, and organic solvents, making it an ideal choice for use in chemical injection quills for corrosive fluids.
  • High temperature resistance: PTFE can withstand high temperatures, making it suitable for use in chemical injection quills for corrosive fluids that are exposed to high temperatures during the process.
  • Low friction: PTFE has a low coefficient of friction, which means that it is a good material for parts that need to move smoothly against other surfaces. This can be beneficial in the design of the chemical injection quills to ensure the smooth flow of the corrosive fluids.
  • Non-stick properties: PTFE has non-stick properties, which means that it does not adhere to other surfaces easily. This can be useful in chemical injection quills for corrosive fluids as it can help to prevent build-up of materials on the surface of the quill.
  • Low thermal expansion: PTFE has a low thermal expansion rate, which means that it does not change size significantly when exposed to changes in temperature. This makes it more stable and less prone to leaks when used in chemical injection quills for corrosive fluids.
  • Low cost: PTFE is relatively less expensive than other materials such as titanium and Hastelloy.

It’s worth noting that PTFE has a relatively low mechanical strength and also it is not recommend for high-pressure applications. However, in cases where chemical resistance is crucial and cost is a concern, PTFE can be an excellent option for chemical injection quills for corrosive fluids.

PVC injection quills manufactured in India. Advantages and disadvantages.

Purpose of PVC injection quills

PVC injection quills are a type of chemical injection system that are used to introduce chemicals or other liquids into industrial processes. They are typically inserted into PVC pipes, and the chemicals are delivered through the quill’s outlet. The purpose of PVC injection quills is to precisely control the amount and timing of chemical delivery, which is important for maintaining the efficiency and effectiveness of the process. This can include tasks such as pH control, corrosion inhibition, and scale and deposit prevention. PVC injection quills are a cost-effective and durable solution for chemical injection in industrial settings.

Advantages of PVC injection quills

A. Ease of installation

PVC injection quills are considered easier to install than other types of chemical injection systems because of several factors:
