Application of ASME SA516 Gr.70 Heat Exchanger Bottom Head
Shell and tube heat exchanger: as the bottom head of the heat exchanger, it supports the tube bundle and distributes the shell/tube media (such as cooling water, hydrocarbon fluid).
Refinery crude oil preheater: medium temperature ≤200°C, design pressure ≤3 MPa, and sulfur-containing crude oil needs to increase the corrosion margin (3~5 mm).
Hydrogenation reactor feed/discharge heat exchanger: withstand hydrogen environment, and require post-weld heat treatment (PWHT) to remove hydrogen.
Condenser and reboiler: liquefied natural gas (LNG) precooling: design temperature as low as -50°C, low-temperature impact toughness needs to be evaluated according to ASME UCS-66.
Waste heat boiler: gas turbine exhaust recovery: flue gas temperature ≤400°C, the head needs to withstand thermal cycle stress, and SA516 Gr.70 normalized plate is used.
Nuclear power plant auxiliary cooling system: non-radioactive fluid heat exchanger: design pressure ≤5 MPa, and must comply with ASME III grade container standards.
Chemical storage tanks: Liquefied petroleum gas (LPG) storage tanks: Design pressure 1.0~2.0 MPa, the head needs to pass the water pressure test (1.3 times the design pressure).
Food and pharmaceutical equipment: Aseptic heat exchanger: The inner surface is polished to Ra≤0.8 μm, in line with FDA hygiene standards.
