Y-Type Strainers
Our PTFE Lined Y-Type Strainers are essential components within the Lined Pipe & Fittings category, designed to mechanically filter particulates and debris from aggressive chemical process lines. They ensure the protection of sensitive downstream equipment (like pumps and instruments) while maintaining a fully corrosion-proof fluid path.
Dual Protection: Lined Body and PTFE Filter
These strainers combine structural strength with a chemically inert filtering element:
- Robust Body: The body and flanges are constructed from durable materials like ASTM A 105, ASTM A 395 (DI), or ASTM A 216 (WCB).
- Size Range: Available in sizes from 25 NB to 250 NB.
- Lining Material: The entire inner surface is seamlessly lined with high-grade polymers, including PFA (conforming to ASTM D-3307), FEP, PP, or PVDF, ensuring a universal chemical barrier.
- Filter Element: Features a robust filter made of 25% Glass Filled PTFE. This inert element provides superior filtration media without compromising chemical resistance.
- Flange Standard: Connections adhere to ANSI B 16.5 and ASA 150# specifications for reliable installation.
Guaranteed Integrity and High-Pressure Capability
Every Y-Type Strainer undergoes stringent testing to ensure dimensional accuracy and a flawless chemical barrier:
| Test | Specification | Result |
| Hydro Test | $14.0 \, \text{kg/cm}^2$ after lining | Confirms excellent pressure handling capability. |
| Spark Test | $15 \, \text{KV DC}$ after Hydro Test | Guarantees $100\%$ lining non-porosity (verified to ASTM F 1545). |
| Dimentions | $100\%$ Visual Check | Ensures precise dimensional accuracy ($\text{F} \pm 3.0 \, \text{mm}$). |
Choose our PTFE Lined Y-Type Strainers to safely and reliably filter your most aggressive chemical streams, extending the life of your critical pipeline assets.
