ASME SA182 CLASS2 Self Reinforced Nozzle With Lip For Heat Exchanger API663
ASME SA182 CLASS2 Self-Reinforced Nozzle with Lip is a critical component engineered for high-pressure thermal equipment, specifically designed to meet ASME Section VIII Div.1 and API 663 standards for heat exchanger construction.
Material Composition (Typical F316L/CLASS 2)
| Element | Content (%) | Function |
|---|---|---|
| Chromium (Cr) | 16.0–18.0 | Corrosion resistance |
| Nickel (Ni) | 10.0–14.0 | Austenite stability |
| Molybdenum (Mo) | 2.0–3.0 | Pitting resistance |
| Carbon (C) | ≤0.03 | Weldability enhancement |
| Manganese (Mn) | ≤2.0 | Strength optimization |
Mechanical Properties
Integrated Design Capabilities
Customization: Lip profiles optimized for shell/tube-side
connections (sizes: 2"–24" NB)
All designs include DWG/STEP files and ASME BPV Code compliance
reports.
Applications in Heat Exchangers
| Component | Function |
|---|---|
| Shell/Tube Connections | Primary pressure boundary for fluid in/outlet (self-reinforced lip resists hoop stress). |
| Channel-to-Tubesheet Joint | Leak-tight sealing under thermal cycling (lip integrates with gasket surfaces). |
| Vent/Drain Nozzles | Compact reinforcement for auxiliary piping per API 663 Sec. 5.4. |
Target Industries & Equipment
Oil & Gas, Equipment: Shell-and-tube exchangers in refineries, LNG cryogenic units.
Chemical Processing, Equipment: Reactor feed heaters, sulfuric acid coolers.
Power Generation, Feedwater heaters, condenser vent nozzles.
