As a global leader in integrated pipeline solutions, Haihao Group has successfully completed delivery of ASME B16.9 A815 UNS S31803 WP-S eccentric reducers to a Singapore client, marking another milestone in serving Southeast Asia’s energy infrastructure sector. This batch of 4″ X 2″ SCH10S X 40S eccentric reducers exemplifies our commitment to precision engineering and material excellence.
ASME B16.9 A815 UNS S31803 WP S eccentric reducer
Technical Excellence Built for Demanding Applications
Manufactured to ASME B16.9 specifications, these duplex stainless steel (UNS S31803) components feature a tapered design that maintains flow continuity while transitioning between 4″ and 2″ pipe diameters. The SCH10S X 40S wall thickness configuration provides optimal balance between mechanical strength and corrosion resistance, making them ideal for:
- Petrochemical processing systems
- Offshore platform pipelines
- LNG terminal infrastructure
- Seawater desalination projects
Material Innovation & Process Control
Each eccentric reducer undergoes a proprietary heat treatment regimen including:
- Solution Annealing: Achieves uniform duplex microstructure (PREN ≥32)
- Pickling Passivation: Removes surface contaminants while enhancing corrosion resistance
- Dimensional Calibration: Ensures ±0.8mm tolerance compliance across bevel angles and taper profiles
