Side Flow Indicators
Our PTFE Lined Side Flow Indicators are essential components within the Lined Pipe & Fittings category, providing a safe, reliable, and chemically inert means of visually inspecting the flow, color, and condition of aggressive media in your process pipeline. They allow critical verification without exposing the fluid to the atmosphere or metal parts.
Safe Visual Monitoring in Corrosive Lines
These flow indicators are engineered to provide clarity and structural integrity in the harshest chemical environments:
- Construction: Features a robust body constructed from materials like ASTM A 105, ASTM A 395 (DI), or ASTM A 216 (WCB), ensuring mechanical strength.
- Visual Element: Utilizes high-quality Borosilicate Glass windows on the sides for exceptional chemical resistance, thermal stability, and clarity.
- Size Range: Available in sizes from 25 NB to 250 NB.
- Flange Standard: All connections adhere to ANSI B 16.5 and ASA 150# specifications for easy and secure installation.
Advanced Fluoropolymer Protection
The entire internal wetted surface is protected to ensure a contamination-free path:
- Lining Material: Seamlessly lined with high-grade polymers, including PFA (conforming to ASTM D-3307), FEP, PP, PVDF, or Antistatic PFA, providing a complete chemical barrier.
- Lining Integrity: The lining thickness is verified to ASTM F 1545 standards.
Guaranteed Quality and Testing
Safety and sealing integrity are paramount, ensured by rigorous testing:
| Test | Specification | Result |
| Hydro Test | $6.0 \, \text{kg/cm}^2$ after lining | Confirms pressure capability under operating conditions. |
| Spark Test | $15 \, \text{KV DC}$ after Hydro Test | Guarantees $100\%$ lining non-porosity for absolute chemical protection. |
| Dimentions | $100\%$ Visual Check | Ensures precise dimensional accuracy and assembly quality. |
