Key Considerations for Plastic Process Vessels

When selecting or buying plastic process vessels, there are several key considerations to keep in mind:

Material of Construction: Choose a material that is compatible with the chemicals or substances being processed. Common materials for plastic process vessels include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and fluoropolymers like PTFE.
Design and Capacity: Consider the design features and capacity that best suit your process requirements. Factors to consider include vessel shape, size, internal baffles or agitators, and working pressure and temperature limits.
Chemical Resistance: Ensure that the plastic material chosen has the appropriate chemical resistance for the substances it will come in contact with during processing.
Temperature and Pressure Ratings: Check that the plastic vessel is rated for the temperatures and pressures expected during the process to ensure safe operation.
Compliance and Certifications: Verify that the plastic vessel meets industry standards and regulations for safety and quality, such as ASME (American Society of Mechanical Engineers) standards or FDA (Food and Drug Administration) regulations if applicable.
Accessories and Features: Consider any additional features needed, such as inlets and outlets, sight glasses, sampling ports, level indicators, pressure relief valves, and temperature sensors.
Manufacturer Reputation: Select a reputable manufacturer with a track record of producing high-quality plastic process vessels that meet industry standards and customer expectations.
Cost and Life Cycle: Evaluate the upfront cost of the vessel along with its expected life cycle and maintenance requirements to assess the overall cost-effectiveness of the investment.

By considering these key factors, you can choose the most suitable plastic process vessel for your specific application. It's also recommended to consult with industry experts or suppliers for further guidance tailored to your unique requirements.
