High temperature and high pressure carbon dioxide static corrosion test kettle

1. Equipment introduction

This equipment is mainly composed of pressurized air circuit, corrosive environment container (test kettle), preheating system, heating system, cooling system, equipment bench, etc.Pressurized air circuitIt is used to continuously pressurize the gas source and pass the pressurized gas into the high-pressure container. The excess gas in the container is released through the unloading valve or back pressure valve and other pressure regulating components on the gas line to maintain the gas pressure in the container.This method is used to pressurize the gas medium, adjust the flow rate or flow rate of the gas, and realize the ventilation function.Preheating systemUsed to preheat the gas output from the high-pressure pump.heating systemUsually, a split heating furnace is used, which is wrapped around the outside of the metal kettle body to heat the medium in the kettle.
