| Selection Factor | Why It Matters |
|---|---|
| Скорость потока | Affects strainer size, velocity, filtration area, and expected pressure drop. |
| Particle Size | Determines the appropriate mesh, perforation, or filtration opening. |
| Dirt Load | Influences filtration area, cleaning frequency, and product type. |
| Allowable Pressure Drop | Helps prevent excessive energy loss or insufficient flow to downstream equipment. |
| Medium Compatibility | Determines suitable body, screen, gasket, and internal materials. |
| Maintenance Strategy | Helps determine whether a simplex, duplex, or self-cleaning solution is appropriate. |
Screen Selection
Mesh, Perforation, and Filtration Opening
The filtration element should capture damaging particles without creating unnecessary pressure loss or excessive cleaning requirements.
- Select the opening around the equipment protection requirement
- Consider particle shape as well as particle size
- Use sufficient open area to control pressure drop
- Consider screen strength under differential pressure
- Evaluate corrosion and temperature resistance
- Avoid selecting an unnecessarily fine mesh
- Review startup debris separately from normal process contamination
Material Options
Materials for Different Process Conditions
Material selection should consider medium compatibility, pressure, temperature, corrosion, erosion, and project specifications.

Часто задаваемые вопросы
Pipeline Filtration FAQ
What is pipeline filtration?
Pipeline filtration is the removal of solids, debris, scale, and other contamination from a flowing medium to protect downstream equipment and improve process reliability.
What is the purpose of an industrial strainer?
An industrial strainer captures particles that could damage pumps, block valves, affect flow meters, foul heat exchangers, or interrupt process operation.
What is the difference between a Y strainer and a basket strainer?
A Y strainer is generally more compact and suitable for lower dirt loads. A basket strainer normally provides a larger filtration area, greater dirt-holding capacity, and easier basket access.
When should I use a duplex strainer?
A duplex strainer is suitable when the process should continue operating during basket cleaning. Flow can be transferred from one chamber to the other without completely stopping the system.
Where should a strainer be installed before a pump?
The strainer is generally installed upstream of the pump with sufficient space for screen or basket removal. The layout should also consider suction conditions and allowable pressure drop.
How do I select the correct strainer mesh?
The mesh or opening should be small enough to protect downstream equipment but not so fine that it causes excessive pressure drop or requires unnecessarily frequent cleaning.
How is strainer pressure drop determined?
Pressure drop depends on flow rate, medium properties, strainer size, body configuration, filtration opening, screen open area, and the amount of collected debris.
Can a strainer be installed vertically?
Some strainer designs can be installed vertically, but the flow direction, screen orientation, debris collection, drainage, and maintenance access must be evaluated.
What is a temporary strainer used for?
A temporary strainer protects equipment during pipeline commissioning, flushing, startup, and initial debris removal. It is normally removed after the system becomes clean.
How often should a strainer be cleaned?
Cleaning frequency depends on dirt load, filtration area, pressure drop, process conditions, and operating experience. Differential-pressure monitoring can help indicate when cleaning is required.
What information is required for a quotation?
Please provide the medium, flow rate, pipe size, pressure, temperature, particle size, required mesh or opening, material, connection, quantity, and project documentation requirements.
Can BCST Valve customize pipeline strainers?
Special sizes, materials, filtration elements, connections, cover designs, nozzle orientations, coatings, and documentation can be evaluated for project-specific requirements.
