The ST34 Flange Connection Right Angle T-type Strainer is a compact filtration device designed for pipelines where space is limited or a 90° flow direction change is needed. It efficiently removes solid particles while minimizing pressure drop.
The ST34 Flange Connection Right Angle T-type Strainer is a compact filtration device designed for pipelines where space is limited or a 90° flow direction change is needed. It efficiently removes solid particles while minimizing pressure drop.
Key Features:
1. Right-Angle (90°) Design
- Redirects flow by 90°, making it ideal for tight spaces or vertical/horizontal transitions.
- Lower pressure drop compared to conventional basket strainers.
2. Flange Connection
- Standard flange options: ANSI B16.5, DIN, GB/T, JIS, etc.
- Common pressure ratings: PN10/16/25 (Class 150/300).
3. T-Type Configuration
- The "T" shape houses the filter screen, allowing easy access for cleaning/replacement without full pipeline disassembly.
4. Filter Screen Material
- Stainless steel (304/316) mesh or perforated plate (common mesh: 20–100).
- Removable for maintenance.
5. Blowdown Valve (Optional)
- Some models include a drain valve for debris removal without opening the strainer.
Typical Applications:
- Steam systems (high-temperature resistance)
- Oil & gas pipelines
- Chemical processing (corrosion-resistant materials available)
- Water treatment & HVAC
Materials & Standards:
- Body Material:
- Cast iron (WCB) – General use
- Carbon steel (A105) – High-pressure applications
- Stainless steel (CF8/CF8M) – Corrosive environments
- Seals: NBR, EPDM, PTFE (for chemical/thermal resistance).
- Standards: ANSI, DIN, GOST, JIS, GB (specify required standard when ordering).
Advantages Over Straight-Through Strainers:
- Space-saving due to 90° design.
- Easier maintenance in cramped installations.
- Lower turbulence compared to basket strainers.
Maintenance Tips:
1. Regularly inspect the screen for clogs (frequency depends on fluid cleanliness).
2. Clean/replace the screen via the T-body cover (no pipe cutting needed).
3. For models with a blowdown valve, purge debris periodically.
