CONFERENCE ON PROTECTING UNDERGROUND CONDUITS
AND CABLES FROM ELECTRICAL CORROSION
Engr I. M. Petrosov, Vice-Chairman, Az VNITOE
Cand Tech Sci N. A. Tsekun
The damage' done by electrical corrosion to underground installations in
large municipalities and on main conduits and cables makes corrosion protection
a most important and pressing problem. Electrical protection methods are the
most effective, in conjunction with measures to increase the contact resistance
between the installations and the soil.
These problems were discussed at a Scientific and Technical Conference held
on 21 - 24 November 1949 in Baku on the initiative of the Azerbaydzhan Division
of the All-Union Scientific and'Technical Society of Power Engineering (VNITOE)
and Azerbaydzhan Industrial Institute (At II) imeni Azizbekov.
The conference aroused great interest among engineers and technicians.
Among the participants were representatives of scientific research institutes,
higher technical educational institutions, and production enterprises of Moscow,
Leningrad, Kiev, Tbilisi, Yerivan, Tashkent, Riga, Ivanovo, Saratov and other
Soviet cities.
S. B. Godzhayev, Candidate in Technical Sciences, Director of the Azerbayd-
zhan Industrial Institute, who opened the conference, stressed the significance
.to the national economy of the problem of protecting underground conduits and
cables from electrical corrosion, and expressed his assurance that the conference
would serve to strengthen further the ties between representatives of science and
,,:production and assist in the successful solution of the complex series of ques-
tions relating to electrical corrosion in underground metallic installations.
The conference heard the reports of Docent V. S. Kal'man, Az II, "Basic Prin-
ciples of the Theory and Design of Grounded DC Networks"; Prof I. N. Frantsevich,
Corresponding Member, Academy of Sciences Ukrainian SSR, "Physico-Chemical Para-
meters of Cathodic Protection"; Engineer V. A. Pritul, "Stal'montazh" Trust, "In-
vestigation of the Corrosion State of Conduits and Corrosion Location Maps," etc.

The report of Docent A, Spirin Candidate in Technical Sciences, Az II,
"The Work of the Earth Currents Laboratory," gave an account of the activities
of this laboratory of the Azerbaydzhan Industrial Institute during the 14 years
of its existence. Instruments and apparatus designed by the laboratory are
widely used in corrosion protection of conduits and cables and many underground
metallic installations have been successfully protected. It has issued a series
of instructions on corrosion examination of underground installations. Much re-
search work has been done in this field.
Reports and communications were also read by L. M. Logov, Candidate in
Technical Sciences, Power Engineering Institute imeni Yes'man, Academy of Sci-
ences Azerbaydzhan SSR; Docent V. F. Gegreyev, Candidate in Technical Sciences,
Azerbaydzhan Scientific Research Institute of Petroleum; B, G. Lordkipanidze,
Candidate in Technical Sciences, Power Engineering Instit.ite, Academy of Sciences
Georgian SSR; N. K. Tsekun, Candidate in Technical Sciences, Az II; Engineer M. S.
Trifel', Bakgaz Trust; Engineer M. D. Dzhafarov, Administration, Saratov-Moscow
Gas Pipeline; and Engineer D. S. Gadzhiyev.
The following took part in the discussion of the reports: M. I. Mikhaylov,
Doctor Technical Sciences, Central Scientific Research Institute of Communications,
Ministry of Communications; Professor F. A. Chirakhov, Leningrad Institute of Sig-
nalling and Communications; B. S. Dikovskiy, Candidate in Technical Sciences, Iva-
novo Power Engineering Institute; A. F. Lunev, Candidate in Chemical Sciences,
Institute of Physical Chemistry, Academy of Sciences USSR; Engineer I. N. Strel'-
tsov, "Mosgazstroy" Trust; Engineer V. I. Zhukov "Stroyneft'" Scientific Research
Institute; Engineer V. V. Lyan, Saratov Streetcar Administration, etc.
Exhibits organized for conference delegates, included apparatus and instru-
ments manufactured by the Earth Currents Laboratory of Az II, and the latest cor-
rosion literature.
The conference passed a number of resolutions. In particular, it recognized
the necessity for organizing a special anticorrosion body, in municipal committees
and ministries, which would have jurisdiction over underground installations. The
following urgent measures are needed to prevent stray currents from electric rail
transport: enlarge the return current network by sufficiently increasing the
number and cross-sections of return feeders to ensure compliance with the specifi-
cations on voltage drop in rail systems; improve the electric conductivity of
lines.by timely removal of broken joints on streetcar lines; and bring the num-
ber of interrail and interline connectors up to the specified quantity.
To provide the national economy with specialists for the struggle against
electrical corrosion of underground installations, the conference decided to re-
quest the Ministry of Higher Education USSR to provide for study of methods for
combating electrical corrosion of underground metallic installations in the pro-
grams of the appropriate higher technical institutions and also to include the
subject "Protection of Underground Metallic Installations against Electrical Cor-
rosion" in the syllabus of courses, improve the qualifications of engineers and
technicians.
In the interests of further successful study of corrosion phenomena in under-
ground metallic installations and scientific research into methods of protection,
the conference recognized the necessity for organizing research on the following
themes: improving the compositions of protective coatings for conduits; investi-
gating the problem of the structure of various insulating coatings in soils with
different corrosion properties; improving anticorrosion coverings of cables; in-
vestigating'protective schemes for underground metallic installations; developing
methods for determining the corrosion properties of soil; developing methods of
designing electrical anticorrosion protection; reviewing regulations for protect-
ing underground metal installations from soil corrosion and stray currents; im-
proving the method of locating damaged insulation on conduits without digging them

ing the field of complex systems; improving errosion maps and a more thorough
investigation of the distribution of stray currents in laige cities and indus-
trial centers with extensive underground installations.
The conference recognized the need for including a mandatory section on
corrosion protection in all conduit and cable plans, and also the establishment
for that

The delegates expressed a desire for publication of litcr^ture and infor-
mation on problems of protecting underground metallic installa,. ons from elec-
trical corrosion.
They recognized the necessity of organizing a VNITOE Committee on "Pro-
tecting Underground and Metallic Installations from Electrical Corrosion."
