Understanding Duplex Type Strainer
Duplex type strainer consist of two parallel filters, each equipped with valves that control the flow of fluid. The system allows for one filter to be isolated for maintenance or cleaning while the other remains operational, ensuring continuous fluid flow. Key components include:
• Valve Bodies: The main structure that houses the valves and connects to the pipeline.
• Filter Elements: The filtering components that remove solid impurities from the fluid.
• Piping and Connections: The system of pipes and connections that direct fluid flow through the filters and valves.
When designing duplex type strainer, several factors must be considered:
• Material Selection: The material must withstand the operating pressures, temperatures, and corrosive nature of the fluid.
• Mechanical Strength: The valve bodies must be robust enough to handle mechanical stresses, including potential impacts.
• Corrosion Resistance: The material should resist corrosion to ensure long-term reliability and minimal maintenance.
• Flow Dynamics: The design should minimize pressure drop and ensure efficient fluid flow.
