What is ASTM A403 WP304L Concentric Reducer
ASTM A403 WP304L concentric reducer is a type of buttweld pipe fitting used to connect pipes of different diameters in a straight line.
Compared with eccentric reducers, concentric reducers are mainly used in:
- Vertical pipelines
- Clean fluid systems
- High-pressure piping
WP304L material features:
- Low carbon content (≤0.035%)
- Excellent corrosion resistance
- Good weldability
- Suitable for food, chemical, and water systems
