Tube sheets in cryogenic equipment must meet low-temperature toughness requirements for materials. Nickel-based alloy steels or austenitic stainless steels are preferred to ensure good impact resistance at extremely low temperatures and prevent the risk of brittle fracture.
The design should be optimized to accommodate low-temperature contraction, such as providing expansion gaps, reducing welding stress concentration, and using full-penetration welds to ensure sealing and prevent leakage.
During manufacturing, strict control of processing accuracy and cleanliness is essential to avoid impurity residue. Furthermore, welding process qualification should be strengthened to ensure the long-term stable operation of the tube sheet under cryogenic conditions.
