Tube sheet
SDFL
Application Scenarios：
Heat Exchangers, Boiler Systems, Chemical Plants, Nuclear Power, Desalination, Oil Refining, Pulp & Paper.
Key Selection Criteria:
1. Pressure Rating
Design: Follow ASME/EN standards for thickness & reinforcement.
Critical Factors:
High pressure (>10 MPa): Thicker plates (e.g., SA-533).
Ligament efficiency (≤45% open area).
Bolt load impacts.
2. Temperature Range
High Temp (>300°C): Creep-resistant alloys (SA-387 Gr.11/22, Inconel).
Low Temp (<-50°C): Impact-tough materials (SA-516 Gr.70 N).
3. Corrosive Environment
Acids: Hastelloy C276, Ti Gr.2, PTFE-lined.
Chlorides: Duplex 2205/2507, 254 SMO SS.
Alkalis: Inconel 600, 316L SS.
4. Manufacturing
Tube Holes: CNC drilling (±0.1 mm tolerance, Ra ≤1.6 μm).
Welding: Full penetration UT/RT tested; clad bonding ≥98%.
5. Standards
ASME: MTR + NB registration.
EU: PED/CE Mark.
Industry: ASME III-NC/ND (nuclear), API 660 (oil)
