Operating Principle
How a Basket Strainer Works
Process fluid enters the strainer body and flows through the removable basket. Particles larger than the basket opening are retained while filtered fluid continues through the outlet.
- Unfiltered fluid enters the strainer inlet.
- Flow is distributed across the basket surface.
- Solid particles remain inside the basket.
- Filtered fluid passes through the screen openings.
- Pressure differential rises as debris accumulates.
- The basket is removed, cleaned and returned to service.
Débit
Determines body size, connection size and required filtration area.
Screen Opening
Must protect downstream equipment without excessive restriction.
Dirt-Holding Capacity
Influences basket area and the interval between cleaning.
Chute de pression
Must remain acceptable in both clean and contaminated conditions.

Questions fréquemment posées
Basket Strainer FAQ
Answers to common questions from engineers, operators and procurement teams.
What is a basket strainer?
A basket strainer is a pipeline filter that uses a removable basket to capture solid particles while allowing the process fluid to continue downstream.
What is the difference between a basket strainer and a Y strainer?
A basket strainer generally provides a larger filtration area and dirt-holding capacity. A Y strainer is more compact and often selected for smaller pipelines or lower debris loading.
When should I use a duplex basket strainer?
A duplex strainer is suitable when filtration must continue while one basket is isolated, removed and cleaned.
How do I select the basket opening?
Select an opening small enough to protect downstream equipment but large enough to maintain acceptable flow and cleaning intervals.
How is basket strainer size determined?
Selection considers pipe size, flow rate, fluid properties, screen opening, filtration area and allowable clean and dirty pressure drop.
How often should the basket be cleaned?
The interval depends on particle concentration and allowable pressure drop. Differential-pressure monitoring provides a practical indication of blockage.
Can the basket be customized?
Project-specific basket openings, materials, reinforcement and filtration areas can be reviewed against the process conditions.
When is a jacketed basket strainer required?
A jacket may be appropriate when the medium can become too viscous, crystallize or solidify as its temperature falls.
Can a basket strainer handle gas or steam?
Selected designs can handle compatible gas or steam service. Body construction, pressure drop, screen strength and drainage must be reviewed.
What information is required for a quotation?
Provide the pipe size, flow rate, pressure, temperature, medium, screen opening, body material, connection standard and maintenance requirements.
