Pipeline Strainer

An industrial strainer is a mechanical device used to remove unwanted solids, debris, or particles from liquids or gases flowing through a pipeline. At Kuncham Controls, our strainers use a perforated or mesh screen element that traps impurities while allowing clean fluid to pass through. This protects pumps, valves, meters, and other equipment from damage, ensures smooth flow, and increases the lifespan of the entire pipeline system.

Kuncham Controls offers several types of strainers commonly used in industrial applications:

• Y-Type Strainer: Compact design for low-to-medium debris loads; ideal for water, steam, chemical lines, and general-purpose filtration.
• Basket Strainer: Higher dirt-holding capacity; ideal for pump suction lines, cooling water systems, and high-flow applications.
• Duplex Strainer: Two-basket design for continuous filtration—no shutdown required during cleaning.
• T-Type / Conical Strainer: Used for temporary or startup filtration to protect equipment during commissioning.

The right strainer depends on flow rate, particle size, fluid type, and maintenance accessibility.

To choose the proper strainer, consider:

• Type of fluid (water, oil, chemicals, steam, viscous fluids)
• Expected particle size and contamination level
• Flow rate and pressure drop limitations
• Screen mesh size required
• Material of construction (CS, SS304, SS316, etc.)
• Connection type (threaded, flanged, welded)
• Ease of cleaning and maintenance
• Operating temperature and pressure

To ensure efficient performance:

• Inspect and clean the strainer regularly—intervals depend on fluid quality and debris load.
• For dirty or sediment-heavy fluids, cleaning may be needed weekly or monthly.
• For clean systems, inspections every 3–6 months may be sufficient.
• Always depressurize the line before opening the strainer.
• Check the screen for damage or clogging and replace if required.
• Ensure gaskets and seals are in good condition to prevent leakage.

Kuncham Controls provides maintenance guidelines and replacement screens for all models.

Common issues include:

• Pressure drop or low flow: Clean the screen—clogging is the most frequent cause.
• Leakage around the cover/flange: Check gasket alignment, retighten bolts, or replace worn seals.
• Incorrect installation direction: Ensure the flow arrow matches the pipeline direction.
• Screen damage or collapse: Caused by high differential pressure—use stronger mesh or clean more frequently.
• Debris bypassing the screen: Indicates incorrect mesh size or a damaged screen element.

For persistent issues, Kuncham Controls Technical Support can help diagnose and recommend corrective actions.
