Applications & Industries
These duplex stainless steel butt welding equal tees are specifically designed for critical applications in:
- Oil and gas processing systems
- Chemical processing plants
- Desalination facilities
- Offshore platforms and marine environments
- Piping systems requiring equal flow distribution
Material Specifications
UNS S31803 duplex stainless steel features a balanced 50:50 microstructure of ferrite and austenite phases, delivering exceptional:
- Corrosion resistance against pitting and crevice corrosion
- High strength and durability
- Performance in aggressive chemical environments
Product Configuration
Tee Types
Equal Tee: All three branches feature identical diameters for uniform flow distribution.
Reducing Tee: Branch diameter is smaller than main line diameter (e.g., 4" x 4" x 3").
