1.Installation Environment
The Hastelloy Alloy High Pressure Reactor should be installed in a high-pressure operating room that meets explosion-proof requirements. When multiple Hastelloy reactors are used, they should be placed separately, with every two reactors isolated by a safety explosion-proof wall. For any passages leading outside, ensure that the equipment is well ventilated in the presence of explosive media.
2.Heating Considerations
If thermal oil electric heating is used, be sure to purchase the appropriate type of thermal oil based on the operating temperature.
3.Sealing the Reactor
The reactor body and lid must make direct linear contact with the gasket or with the conical and arcuate sealing surfaces. Tightening the main nut presses them together to achieve an effective seal. When tightening, the nut should be turned symmetrically and gradually in several stages to ensure even pressure and to prevent the lid from tilting, thereby ensuring a proper seal.
4.Valve and Gauge Installation
Install valves, pressure gauges, and safety valves by tightening the corresponding nuts to achieve a seal. The arcuate sealing surfaces on both ends of the connection must not rotate relative to each other. During assembly, all threaded joints must be lubricated—either with a suitable lubricant or a graphite-oil mixture—to prevent galling.
5.Cooling Process
For cooling, water can be circulated through internal cooling coils. Rapid cooling is prohibited to avoid excessive thermal stress that may crack the cooling coils and reactor body. During operation, if the reactor temperature exceeds 100°C, cooling water should be circulated through the water jacket between the magnetic stirrer and the reactor lid to ensure the water temperature remains below 35°C, which helps prevent demagnetization of the magnet.
6.Post-Reaction Procedures
After the reaction is complete, first allow the reactor to cool, then release the internal gas through the pipeline to reduce the pressure to atmospheric pressure. Do not disassemble the reactor while it is still pressurized. Symmetrically loosen the main bolts and nuts, remove them, then carefully open and lift off the lid, placing it on a stand.
Maintenance and Cleaning
After each operation, clean the reactor with a suitable cleaning fluid to prevent corrosion of the main materials. Remove any residues from the reactor body and sealing surfaces. Always keep the equipment clean.
