Our PTFE Lined Eccentric Reducers are specialised fittings within the Lined Pipe & Fittings category, designed to create a secure, corrosion-free transition between two different pipe sizes with an offset centerline.1 This design is essential for horizontal process lines, especially on pump suctions or in applications where eliminating air or vapour pockets is critical to flow stability and equipment protection.
Robust Construction and Essential Offset Design
These reducers combine mechanical strength with a crucial offset for optimal fluid dynamics in specific applications:
- Construction: The metal shell is made from ASTM A 234 Gr. WPB, ensuring structural durability, complemented by ASTM A 105 or other robust flanges (DI/WCB).
- Eccentricity: The offset centerline allows the fitting to be installed with the flat side either on the top (for liquid service) or the bottom (for gas/vapour service), preventing air/liquid entrapment.
- Size Transitions: Available in various size combinations (e.g., $40\text{NB}$ to $25\text{NB}$ up to $250\text{NB}$ to $200\text{NB}$) to meet precise process requirements.
- Flange Standard: All connections adhere strictly to ANSI B16.5 and ASA 150# specifications for reliable installation.
Advanced Fluoropolymer Protection
The internal lining provides a complete chemical barrier and is verified for long-term reliability:
- Lining Material: Seamlessly lined with high-grade PTFE (conforming to ASTM D-4895/4894) or other specified fluoropolymers like PFA, FEP, PP, and PVDF, ensuring a completely inert flow path.
- Guaranteed Integrity: Every reducer undergoes a high-pressure $29.0 \, \text{kg/cm}^2$ Hydro Test and a $15 \, \text{KV DC}$ Spark Test to verify $100\%$ lining non-porosity (verified to ASTM F 1545).
