Product Detail
Product Introduction
Titanium reducers are transition fittings that connect two different pipe sizes. The family includes concentric reducers, whose end centerlines coincide, and eccentric reducers, whose offset helps maintain a flat side. Select geometry from piping orientation, drainage, gas-pocket control and available space, then define both end sizes, walls, length and weld ends.
When should a concentric or eccentric titanium reducer be used?
Selection answer: A concentric reducer keeps the pipe centerlines aligned, while an eccentric reducer offsets them to support drainage, venting or pump-suction layout. The piping designer should select the orientation and geometry.
Selection boundary: Nominal end sizes alone do not define a reducer. State large and small ends, wall or schedule at both ends, overall length, eccentric orientation, grade, forming route and weld-end details.
RFQ data to confirm: Provide concentric or eccentric type, large and small NPS or OD, wall or schedule, length, orientation, grade, standard or drawing, seamless or welded route, service conditions, quantity, NDE and certificates.

Selection and Configuration
- Concentric reducer: Centered transition suited to many vertical and symmetric layouts; evaluate pooling or gas pockets in horizontal service.
- Eccentric reducer: Offset transition used when a flat side is needed for drainage, pump suction or air-pocket control.
- Complete size definition: State large and small NPS or OD, wall/schedule at both ends, overall length, orientation and end preparation.

Corrosion-resistant piping for acids, chlorides and process media after grade compatibility review.
Power & Energy
Cooling-water, condenser and auxiliary piping requiring traceable titanium components.
Marine & Desalination
Seawater and chloride-bearing piping systems designed for the selected titanium grade.
FAQ
Should I choose a concentric or eccentric reducer?
Choose from piping orientation and process needs. Concentric reducers are centered; eccentric reducers provide a flat side for drainage or pocket control.
What does flat side up or down mean?
It defines eccentric-reducer orientation. The piping designer should specify the required flat side relative to flow and equipment.
Are both end schedules required?
Yes. Provide size and wall or schedule at the large and small ends because they may differ.
