Device for on-line monitoring of corrosion of metals and physico-chemical parameters of the corrosive medium, preferably in the geothermal systems

摘要

The purpose of the notification is to monitor on -line corrosion of metals and physicochemical parameters of the corrosion medium, especially in geothermal installations.an on -line monitoring device for corrosion of metals and physicochemical parameters of the corrosion medium, in particular in geothermal installations,has a by pass connected to short -circuit valves from segmented pipes with fitted meters, belt coupons and measuring sockets,where these nests are fitted with electrochemical sensors with electrodes tested, polarised and referenced,electrical wires transmitting signals from electrochemical meters and sensors to the computer module, the parameters being flow rate, pressure, temperature meters,pH, and /or redox potential, are characterised by having sensors with test electrodes made of materials of different chemical composition mounted in the sockets (8) of the segment (S -Ech),the crystallographic structure of the metal and /or the different coatings of the protective surface and between the loose flanges of the segment pipes (11) segment (S -Str) fitted with a cap frameElves. A convenient flat ring frame has a bent foot attached to the plane for mounting the belt coupon.A conveniently mounting handle bent from the inner edge of the frame ring is parallel to the axis of the tube segment (11).The device has a short power supply (20) on the measuring segment (S).The new device, as notified, can be connected as a by -pass in any location of the thermal water pipeline.
