And DESIGNING of ELECTROCHEMICAL PROTECTION of PIPELINE NETWORKS FROM CORROSION
Computer complex ÀÐÌ-ÝÕÇ-9 is intended for application at training,
calculation, designing and adjustment of systems of electrochemical protection (ÝÕÇ)
of underground pipeline networks of an any configuration and assignment. Into a
1. ÀÐÌ-ÝÕÇ-9Ï - calculation, designing and the numerical
analysis of functioning of any system ÝÕÇ
of non-uniform pipeline networks.
2. ÀÐÌ-ÝÕÇ-9Ñ - budget calculations and formation of a database
on erection works on ÝÕÇ.
3. ÀÐÌ-ÝÕÇ-9Ó - training and the control of knowledge under the
theory and practice ÝÕÇ (a computer textbook - simulator).

1. Features of package ÀÐÌ-ÝÕÇ-9Ï
at comparison with package ÀÐÌ-ÝÕÇ-8Ï.
§ Graphic, instead of digital input of the circuit of a
pipeline network, it is direct from the card - plan with the help of the cursor
of a mousy, instead of with the help of the keyboard under beforehand prepared
table of coordinates;
§ The number of units of the digitization describing a
configuration of a pipeline network, practically is not limited, that allows to
investigate a field of currents of corrosion and protection with higher degree
of detailed elaboration and reliability;
§ Time for input of units of digitization by a graphic
method is not enough, as is spent only for moving of the cursor along a line of
the pipeline with fixing - with any step of digitization - in casual points
which position in aggregate should set a line of the pipeline with its branches
and turns - in correct conformity with a practicable plan of a network;
§ The prepared circuit easily may be edited, i.e. units
of digitization may move, be added or leave, and besides graphic receptions on
the screen of the computer;
§ By quantity(amount) and position prospective cathodic
protection installations with its anodes similarly graphically may be entered
and edited, having in view of, that programs ÀÐÌ-ÝÕÇ-9Ï
solve the optimization task - a choice of one circuit of accommodation of
from set offered;
§ At formation of the settlement circuit the next
pipelines which may cause distortion of a field of currents of corrosion and
protection also are graphically taken into account; at updating the circuit
pipelines may be incorporated by crosspieces or, on the contrary, are shared by
§ Such constructions may be added to the pipeline
entered graphically as underground tanks, the pile bases of the ferro-concrete
bases, galvanically alien metal constructions, let alone that each of pieces of
digitization may have own parameters - diameter, thickness of a wall, specific
electric resistance of isolation, the electrochemical potential specifying
galvanic heterogeneity of a network.
2. The primary goals solved with use of package ÀÐÌ-ÝÕÇ-9Ï
§ To define optimum quantity and the circuit of
accommodation of installations ÝÕÇ, size of their currents and distribution of
protective potential, proceeding from conditions of a minimum of a total
protective current and the given range of change of protective potential in
researched area (the optimization task decided in an automated mode);
§ To define a field of protective potential and an
operative range of installations ÝÕÇ at the known circuit of their accommodation and
given currents ÝÕÇ (a direct task);
§ To define size of specific electric resistance of
isolation in researched points of a pipeline network on the measured
distribution of protective potential at ÝÕÇ
(a return task).
3. Other decided tasks
§ To calculate parameters anods with use typical or any
on a design rods;
§ To determine protective effect at use group galvanic
anodes of any configuration;
§ To calculate distribution of a gradient of potential
in the ground for comparison to results of natural measurements, for example, at
an estimation of integrity and quality of an insulating cover of the pipeline;
§ On the measured gradients of potential in the ground
to calculate density of a current of the pipeline and size specific electric
resistance of isolation in the given point of a line and so forth.
