Web1 okt. 2007 · Abstract The copper strip corrosion test (CSCT) is used to measure the corrosivity of sulfur compounds in fluids. The CSCT is performed by immersing a strip of cleaned, polished copper in a fluid at a specified temperature for a predetermined time, then reading the strip against a standard. WebCorrosion Guidebook – Part 3. In the first two parts of the Corrosion guide, we dealt with the different types of corrosion and also looked closely at different ways of reducing corrosion damage. In this part we will look at the assessment of the corrosion environment and explain the corrosivity categories and corrosion resistance classes.

WebPressure sensors for corrosive media are transducers, generating an electrical signal in proportion to the pressure they measure. This allows pressure to be monitored by various devices with a suitable interface. Most pressure sensors for use with corrosive media use the principle of piezoresistance.
