Manufacturing Technology of Large Diameter Medium-High Pressure Floating Head Heat Exchanger
This article introduces the control of key manufacturing points for large diameter high-pressure floating head heat exchangers,and proposes a floating head side pressure testing fixture to solve the difficulty of sealing the gap between the pressure testing fixture and the outer circle of the floating tube plate when the shell side pressure is high.This provides certain reference experience for key processes such as bundle assembly and pressure testing of similar products.
