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.

Advantages of PVDF bodied chemical injection quills manufactured in India

PVDF, or polyvinylidene fluoride, is a type of thermoplastic that is highly resistant to chemical reactions and can be used in chemical injection quills for corrosive fluids. The advantages of PVDF include:

  • Chemical resistance: PVDF 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. It also has good resistance to chlorine, hydrogen peroxide, and other oxidizing agents.
  • High temperature resistance: PVDF 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.
  • High mechanical strength: PVDF has high mechanical strength and can be used in high-pressure applications.
  • UV resistance: PVDF has good resistance to UV radiation making it suitable for outdoor applications.
  • Low thermal expansion: PVDF 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.
  • Good electrical insulation: PVDF is a good electrical insulator, which can be beneficial in certain applications where electrical insulation is required.
  • Low cost: PVDF is relatively less expensive than other materials such as titanium and Hastelloy

It’s worth noting that PVDF is not recommended for certain types of organic solvents and also it is sensitive to stress cracking when exposed to certain chemicals at high temperatures. However, for applications that require high chemical resistance and high-pressure handling, PVDF is a good option for chemical injection quills for corrosive fluids.

Advantages of PFA bodied chemical injection quills manufactured in India

PFA, or perfluoroalkoxy, is a type of thermoplastic that is highly resistant to chemical reactions and can be used in chemical injection quills for corrosive fluids. The advantages of PFA include:

  • Chemical resistance: PFA 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. It has excellent resistance to strong acids, bases, and organic solvents.
  • High temperature resistance: PFA 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.
  • High mechanical strength: PFA has high mechanical strength and can be used in high-pressure applications.
  • Low thermal expansion: PFA 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.
  • Good electrical insulation: PFA is a good electrical insulator, which can be beneficial in certain applications where electrical insulation is required.
  • Low coefficient of friction: PFA 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.
  • Good thermal stability: PFA has good thermal stability, meaning that it maintains its properties even when exposed to high temperatures for an extended period of time.

It’s worth noting that PFA is relatively expensive than other materials such as PVC, PTFE, and PVDF. However, for applications that require high chemical resistance and high-pressure handling, PFA is a good option for chemical injection quills for corrosive fluids.

Advantages of PP bodied chemical injection quills manufactured in India

PP, or polypropylene, is a type of thermoplastic that is often used in chemical injection quills for corrosive fluids due to its chemical resistance properties. The advantages of PP include:

  • Chemical resistance: PP is 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. It is particularly resistant to strong acids and bases.
  • High temperature resistance: PP 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.
  • High mechanical strength: PP has high mechanical strength and can be used in high-pressure applications.
  • Low thermal expansion: PP 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.
  • Good electrical insulation: PP is a good electrical insulator, which can be beneficial in certain applications where electrical insulation is required.
  • Low coefficient of friction: PP 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.
  • Low cost: PP is relatively less expensive than other materials such as PTFE and PVDF

It’s worth noting that PP is not recommended for use in certain applications, particularly in strong oxidizing agents, and also in high-temperature applications where the chemical resistance of PP may be diminished. However, for applications that require chemical resistance and high-pressure handling, PP is a good option for chemical injection quills for corrosive fluids.

Advantages of PVC bodied chemical injection quills manufactured in India

PVC, or polyvinyl chloride, is a type of thermoplastic that is often used in chemical injection quills for corrosive fluids due to its chemical resistance properties and low cost. The advantages of PVC include:
