ASME SA266 Gr.2N carbon steel tube sheet is the preferred material for conventional heat exchangers and boiler equipment due to its economy, easy processing and medium temperature strength. When selecting, it is necessary to strictly evaluate the corrosiveness of the medium and the temperature and pressure conditions, and use protective coatings or upgraded materials when necessary. For high-risk conditions (such as sour oil and gas, seawater cooling), stainless steel or composite plates are recommended to ensure long-term reliability.
