Mendeleevets-MRV - anodes for internal protection
Certification:
Technical details
An internal anode grounding consists of MMO anodes Mendeleevets-MRV and is meant for installation in pipelines and tanks.
Installation of internal anodes is provided in tanks and on sites of pipelines with the constant level of electrolyte, and also in places of a liquid phase with low value of specific electric resistance.
Installation of anodes on internal surfaces of pipes and tanks needs to be carried out on the designs excluding any possibility of electric contact of anode grounding and the protected metal construction.
Installation of MMO anodes is made manually without use of any special equipment.
Free ends of connecting cables of internal anodes are brought out on the surface and connected to control equipment.
Cable joining isolation is made with thermocontracting materials.
