Distillation unit oil and residue heat exchanger maintenance
Monitor the temperature：370℃，Tube side pressure：20kg/cm²
Problem：Temperature fluctuation has a great influence on the pretightening force of bolts, and leakage of tube box and head often occurs, which has great security risks
Solution：High temperature disc spring 20813
Effective：The high temperature leakage medium is effectively solved, reducing the frequency of maintenance and eliminating safety risks. Ensure long, stable, full and excellent operation.
