Strainer FAQ
What's the typical lifespan of industrial strainers?
Industrial strainers typically last 5-10 years with proper maintenance. The exact lifespan depends on operating conditions, material selection, and maintenance frequency. High-grade stainless steel strainers in moderate conditions often reach the upper end of this range, while plastic strainers in harsh chemical environments may require replacement sooner.
How often should strainers be cleaned?
Strainers should be cleaned based on pressure differential readings. For most applications, we recommend inspection every 2-4 weeks. Critical systems may require weekly cleaning. Always clean when the pressure drop across the strainer exceeds the manufacturer's recommended ΔP value (typically 5-10 psi for standard models).
Can strainers handle corrosive fluids?
Yes, when properly specified. For corrosive applications, we recommend 316 stainless steel, Hastelloy, or specialized plastic strainers. The material selection depends on the specific chemical composition, concentration, temperature, and flow characteristics of the fluid. Always consult our corrosion resistance charts before selecting a strainer for harsh chemical service.
Installation Guidelines
- Install strainers with adequate clearance for basket removal
- Position according to flow direction arrows
- Support piping properly to prevent strain on connections
- Include isolation valves for maintenance
- For vertical installation, ensure proper orientation (typically basket down)
More Strainer FAQs
What's the difference between simplex and duplex strainers?
Simplex strainers have a single basket that requires system shutdown for cleaning, while duplex strainers feature two parallel baskets with diverting valves that allow continuous operation during cleaning. Duplex models are essential for critical processes where uninterrupted flow is required, though they cost approximately 40-60% more than comparable simplex units.
How do I select the right mesh size?
Mesh selection depends on the particle size you need to capture. As a rule of thumb, choose a mesh opening 20-30% smaller than the smallest particle you want to filter. Consider both the initial cleanliness of your fluid and potential particle generation during system operation. Finer meshes provide better protection but require more frequent cleaning and cause greater pressure drops.
Are strainers suitable for gas applications?
Yes, specially designed strainers work effectively for gas services. Gas strainers typically have heavier construction to withstand pulsation and higher velocities. They often incorporate special basket designs to handle the different flow characteristics of gases compared to liquids. Always verify the pressure rating and ensure proper material selection for gas composition and operating conditions.
Maintenance Best Practices
| Maintenance Task | Frequency | Procedure |
|---|---|---|
| Visual Inspection | Monthly | Check for leaks, corrosion, and structural integrity |
| Basket Cleaning | As needed (monitor ΔP) | Remove, clean with appropriate solvent, inspect for damage |
| Gasket Replacement | Annually | Replace all gaskets during major maintenance |
| Full Inspection | Every 2 years | Complete disassembly and professional inspection |
