A Guide to Selecting the Correct Size and Length for Specific Drug Manufacturing Processes


Pharmaceutical tubing plays a vital role in drug manufacturing processes, facilitating the transfer of liquids and gases between containers and equipment.

To ensure efficiency and safety, it is crucial to carefully choose the appropriate pharma tubing size and length. Let’s discuss the necessary steps in selecting the right tubing size and length for specific drug manufacturing processes.

  1. Determine the required flow rate: To select the correct pharma tubing size, it is important to establish the desired flow rateā€”the quantity of liquid or gas to be transferred within a specific time frame. Factors like liquid viscosity, system pressure, and tubing diameter influence the flow rate.
  2. Calculate the pressure drop: The pressure drop refers to the decrease in pressure as the liquid or gas flows through the tubing. Calculating the pressure drop helps in determining the appropriate tubing size. Factors such as tubing diameter, length, and fluid properties affect the pressure drop.
  3. Consider the fluid properties: When selecting the tubing size and length, it is necessary to take into account the properties of the fluid being transferred. Factors such as viscosity, density, and surface tension can impact the flow rate and pressure drop within the system.
  4. Choose the correct tubing material: The choice of tubing material is another critical aspect in selecting the right tubing size and length. The material should be compatible with the fluid, resistant to chemicals and heat, and compliant with regulatory requirements.
  5. Determine the required length: The length of the tubing depends on the distance between containers and equipment, as well as the desired flow rate of the fluid. Longer tubing lengths can result in higher pressure drops, while shorter lengths may lead to flow rate issues.
  6. Consult a tubing size and length chart: Tubing manufacturers provide charts that assist in determining the appropriate tubing size and length for specific drug manufacturing processes. These charts consider factors such as flow rate, pressure drop, and fluid properties, simplifying the selection process.

In conclusion, selecting the correct tubing size and length is crucial for the efficiency and safety of drug manufacturing processes. By considering factors like flow rate, pressure drop, fluid properties, and tubing material, and consulting manufacturer size and length charts, you can make informed decisions regarding the tubing size and length for your specific drug manufacturing needs.
