Unequal Tees
Our PTFE Lined Unequal Tees are specialized fittings within the Lined Pipe & Fittings category, designed to create a secure, corrosion-free $90^\circ$ branch connection where the branch port (Size 2) is smaller than the main line (Size 1). These tees facilitate both flow division and reduction simultaneously, maintaining the structural and chemical integrity of the pipeline.
High-Integrity Construction and Versatile Lining
Engineered for reliable performance in complex chemical systems, our Unequal Tees feature robust housing and advanced fluoropolymer lining:
- Piping Base: Constructed from ASTM A 106 Gr. B Schedule 40 Pipe for the body, with flanges made from ASTM A 105, ASTM A 395 (DI), or ASTM A 216 (WCB).
- Size Versatility: Available in a comprehensive matrix of sizes, allowing for precise transitions (e.g., 25NB to 15NB up to 250NB to 200NB, as per our data sheet).
- Lining Material: Seamlessly lined with high-performance polymers, including PFA (conforming to ASTM D-3307), FEP, PP, PVDF, or Antistatic PFA, ensuring a completely inert fluid path.
- Flange Standard: All three flanged connections strictly adhere to ANSI B 16.5 and ASA 150# specifications for reliable and universal integration.
Guaranteed Quality and Structural Durability
Every Unequal Tee is subjected to rigorous testing to ensure a non-porous chemical barrier and structural durability:
| Test | Specification | Result |
| Hydro Test | $29.0 \, \text{kg/cm}^2$ after lining | Confirms high-pressure endurance. |
| 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 ($\text{F} \pm 3.0 \, \text{mm}$). |
Rely on our PTFE Lined Unequal Tees for safe, efficient, and corrosion-proof flow reduction and division in your most aggressive processing lines.
