Product Selection Differences for Hygienic Process Plant Pipework

When selecting hygienic process plant pipework, there are several key differences to consider among the available options. Here are some important factors to take into account:

1. Material: The choice of material is crucial for hygienic process plant pipework. Stainless steel, particularly austenitic grades like 316L, is commonly used due to its corrosion resistance, smooth surface finish, and compatibility with sanitary requirements. Other materials such as plastic (e.g., PVC, CPVC, and polyethylene) and glass-lined steel may also be suitable for specific applications.

2. Surface Finish: The smoothness and finish of the pipework interior are critical for hygienic applications to prevent bacterial growth and facilitate easy cleaning. Electropolishing or mechanical polishing can be used to achieve the required surface finish.

3. Connections and Fittings: Hygienic process plant pipework should incorporate sanitary fittings such as tri-clamp, dairy, or DIN standard connections to ensure proper sealing and ease of disassembly for cleaning and maintenance.

4. Compliance: It's essential to ensure that the selected pipework meets relevant industry standards and regulations, such as ASME BPE (Bioprocessing Equipment), EHEDG (European Hygienic Engineering & Design Group), 3-A Sanitary Standards, or FDA requirements.

5. Pressure and Temperature Rating: Consider the operating conditions of your process plant to select pipework that can withstand the required pressure and temperature ranges.

6. Flexibility: Depending on the layout and requirements of your process plant, consider whether rigid pipework or flexible tubing would be more suitable for installation and maintenance purposes.

7. Cost: Evaluate the initial cost as well as long-term maintenance and cleaning costs associated with the different pipework options to ensure cost-effectiveness over the lifecycle of the plant.

By carefully considering these factors and consulting with experts in hygienic process plant design and engineering, you can select the most appropriate pipework for your specific industry and application requirements.
