Equipment for observation of corrosion protection of underground pipelines

Portable rout detector – for identification of the direction of alternative current field.
Portable depth gauge - for measuring the distance to the axis of underground pipelines ( UP).
Portable voltmeter– for measuring the difference between electric potentials and control of the electrochemical protection.
Non-contact current gauges – for determination of current between branches and regions of UP and detection of UP insulation damages.
   Designation:
     A set of devices is designed to carry out on-line control of the state of insulation coatings and electrochemical to reveal corrosion sites in pipelines without their digging out.
     Owing to its portability the device can be used for investigations in sites that are reached with difficulty.
    Equipment capabilities:
    – Determination of the place, direction, depth of underground communications location ( pipelines, cables);
    – Corrosion protection monitoring ( insulation and cathode polarization currents) using non-contact method;
    – Search of corrosion sites for prevention of pipelines damaging;
    – Allows by non-contact method to determine electric current value.
    Advantages of the equipment:
    Availability of a large number of devices and possibility of their common use makes it possible a high quality adjustment to specific objects and conditions.
   Equipment can be used in:     oil and gas industries, communal services, power generating industry, communication, etc.
    Equipment for observation of the corrosion protection of underground pipelines proved to be effective ( gave good results) when performing works at gas pipeline companies “ Naftogaz” of Ukraine, “Lvivtransgaz”, “ Integrator”, “ Promtekhdiagnostyka”,”Lokachynskyi, Pasichnianskyi, Khidnovytskyi and Stryi gas pipelines of gas productionadministration “ Lvivgazvydibuvannia”.
