Development of A Temperature and Pressure-Controlled Corrosion Test Vessel

摘要

Temperature and pressure are very important factors that influence corrosion process. We often need to choose a proper vessel in the corrosion test that need to control both temperature and pressure. Moreover, the material of the test vessel should not be harmful to corrosion liquid. For example, steel even stainless steel will be corroded in warm seawater, and they are not suitable for the vessel material. We designed a corrosion test vessel made of Poly-Propylene Random (PPR), and temperature can be controlled within room temperature and 100Celsius degree, pressure can be controlled within 1 to 10atm. (1MPa). In this paper, temperature-controlled method and pressure-controlled method are described. Temperature and pressure characteristics are also analyzed and described. Shell structure, material and design are introduced. A series of typical corrosion tests were performed by using this corrosion test vessel.
