 Classification of explosion-proof equipment
Explosion-proof electrical equipment is electrical equipment designed to prevent or hinder the risk of ignition
of the surrounding explosive atmosphere due to the operation of the equipment.
In potentially explosive areas, explosion-proof electrical equipment must be installed, whose design and specifi-
cations correspond to the explosion hazard area class and the properties of the explosive mixture.
Depending on the application, explosion-proof electrical equipment is classified into the following groups

 Choosing the right type of heating cable

Before the heating cable type and grade can be correctly specified, thermal design needs to be prepared. Thermal
design is prepared for each of the pipelines.
For thermal design calculations, the software suite TeplomagPro can be used that was developed specifically for
calculating the heat losses of pipelines and tanks and specifying heating cables and components.

TeploMagPro supports quick and convenient calculation of the heat losses of pipelines and tanks, selection of the self-regulating or series-
resistance heating cable grade and preparing a specification of the electric heating system components and generating summary project
documents.
With the help of TeploMagPro, the heating time of a pipeline (empty or filled with liquid) can be estimated from the set initial temperature
to the maintenance temperature with the electric heating system activated.
In the case of a power failure in the electric trace heating system, the pipeline and the liquid will begin to cool down.
TeploMagPro can calculate the cooling time of the pipeline from the initial temperature to the specified final temperature.
of heating cable
Choosing the right type

The software supports heat loss calculations from the surface of outdoor, indoor, underground and underwater pipelines.
Thermal loss rates calculated by the software satisfy the requirements of GOST IEC 60079-30-2-2011, SP 41-103-2000, IEEE 844-2000.
For more information visit www.sst.ru/en and www.sst-international.com.

You can also specify the appropriate heating cable yourself by following the steps described below:
1. Estimate the thermal losses of the system to be heated
2. Select heating cable grade
3. Select heating cable power
4. Calculate heating cable length

Step 1: Thermal loss table

Table 1 shows typical design thermal losses of pipelines depending on diameter, temperature difference between
the pipeline and the environment and the thermal insulation thickness.
1. Choose pipeline diameter
2. Choose thermal insulation thickness and temperature difference
3. At the intersection of the respective column and row find the thermal loss value
The calculation in the table is valid for the following conditions: pipeline is thermally insulated with a thermal
conductivity coefficient of 0.05 W/(m•°C). For other conditions, make the following adjustment:

0.045 – 0.055 1
0.055 – 0.07 1.2

The result of this calculation is the thermal loss of the pipeline while maintaining the required temperature for
further selection of the heating cable grade.

Example:
outdoot steel pipeline Dn 159 mm
thermal insulation – mineral wool 50 mm
maintainance temperature +10 °С
minimum ambient temperature -40 °С
Thus: the difference between the pipeline temperature and the ambient temperature is ΔТ=10-(-40)=50 °С
From Table 1: thermal loss of the pipeline is Qtab=31.36 W/m
Total thermal loss of the pipeline:
Qtot.= Qtable×К1×К2×К3×Е=31.36×1×1×1×1.1=34.5 W/m.

 Step 2: Select the heating cable grade
The heating cable grade is selected in accordance with the calculated thermal losses, taking into account the
maximum operating temperature of the heating cable, its thermal output at the maintainance temperature and the
exposure likelihood of the heating cable to any aggressive substances.

Step 3: Select the heating cable power

Each self-regulating heating cable has a temperature profile of thermal output as a function of the heated system
temperature.
The relationships characterizing nominal thermal output of self-regulating heating cables at an operating voltage
of heating cable
Choosing the right type

of 230 V are presented in the catalog (see pp. 19-31).

If the thermal losses of the pipeline slightly exceed the nominal power rating of the heating cable, the winding
coefficient can be applied, i.e. the pipeline can be traced with more than 1 running meter of heating cable per
1 running meter of the pipeline (for example, with a winding coefficient of 1.1. . .1.3, but not higher than 1.5 m/m).
To observe the minimum bending radius of the heating cable the pipeline must have a diameter of at least 57 mm.
The minimum bending radius is indicated in the technical specifications included in this catalog.

Step 4: Calculate the heating cable length

The length of the heating cable is determined for each pipeline on a case by case basis. The total length of the
heating cable is the sum of the stretches required for each component of the pipeline system. When calculating
the length of the heating stretch for each pipeline section, extra length should be added to compensate for the
thermal losses via valves, flanged connections, pipe supports, etc.
More detailed information on selecting the heating cable, designing trace heating systems, and specifying the
components can be found in our handbooks available in Russian.
Manual on designing electric heating systems based on self-regulating heating cable describes the general
methods of designing electric trace heating systems and offers a step-by-step project completion algorithm —
from collecting the design inputs to design approval.
The manual “General design principles of electric heating systems based on the resistive heating cable LLS”
describes the general principles of designing trace heating longline systems based on resistive LLS cable.
The manual “General design principles of induction resistive electric heating systems IRHS-15000” describes the
general principles of designing trace heating systems of the type IRHS-15000 (skin-system).

 CALCULATION OF PIPELINE COOLING TIME

The main purpose of the systems offered by SST Group is to maintain the required temperature in the heated
pipelines by compensating for thermal losses. However, in case of scheduled or emergency repairs, the power
supply can be turned off.
When the power is off, the pipeline trace heating system can no longer compensate for the thermal losses to the
environment. Power outage will, in addition, cause pumps to stop. Pumping of liquid will stop. The pipeline will
gradually cool down. Pipelines filled with liquid and thermally insulated have significant thermal inertia, and the
larger the pipe diameter and the higher the permissible cooling of the liquid, the higher is the pipeline’s thermal
inertia.
For maintenance units, it is important to know the maximum permissible power outage time of the pipeline trace
heating systems. The tables below show the cooling time estimated for some standard pipeline designs with inside

diameters from 50 to 400 mm. In the presented cases, the pipelines are completely filled with oil or water. The
pipes are thermally insulated with mineral wool, whose thermal conductivity coefficient is assumed to be
0.05 W/m•°C. The input values used in the calculations are shown in Table 2.

Table 3 presents the calculation results of the cooling time of pipelines filled with medium-density oil, depending
on the ambient air temperature. In addition to pipe dimensions, thermal insulation thickness and density are also
indicated. The oil temperature at the time of the power outage is 50 °С. It is assumed that the minimum temperature
that the oil can cool down to is +20 °C. The table shows the cooling time of the pipelines as a function of the
pipeline design and thermal insulation, as well as ambient air temperature. Obviously, the higher the ambient air
temperature, the slower the pipeline cools.

 Table 4 shows the effect of the thermal insulation thickness on the cooling time. The calculation is based on an
oil-filled pipeline with a diameter of 150 mm. Insulation thickness varied from 30 to 60 mm. Doubling the thermal
insulation thickness produces a nearly double increase in the cooling time. This solution can be used to extend the
cooling time of the pipeline.

Table 5 shows the cooling time of a water-filled pipeline. The water temperature in a heated pipeline is usually
maintained at 5-8 °C during the cold season, and cooling below 2 °C is undesirable. Table 5 is structured similarly
to Table 3. Although the thermal capacity of 1 kg of water is 2.6 times greater than that of 1 kg of oil, the narrower
permissible cooling range leads to shorter permissible cooling time.

Operator AWS

121
 Structure of the control system (CS):
Operator AWS with SCADA is located in the opera-
tor room and is indended for centralized display of
control parameters and control of the entire distrib-
uted EHS in real time with the help of a GUI. Oper-
ator AWS has functions of control, archiving, man-
agement, diagnostics, and output of reference
information.
Servers are located in the same building as the oper-
ator room and collect, archive, and make data in the
required format available to the operator AWS.
When the volume of data is small, the server can be
combined with the operator AWS.
Telecom cabinets (TCs) are installed in the same
room as the AC. TCs collect information from AC
PLCs and transmit this information to the servers
via a fiber optic link.
Fiber-optic communication link (FOCL) connects in
an optical ring the TCs with the servers into a single
data network.
The local controller network is a cable local area net-
work for data sharing between the CC controllers and
the TC switch.

Functions of the control system:

Visualization. Display of monitored parameters (sys-
tem temperature, ambient temperature, EHS power
parameters). Display of the general proces diagram of
the site indicating control points and heating lines.
Control. Selection of operating mode, temperature
settings, control of the electric heating system.
Automated control systems

Archiving. Recording the values of monitored param-

eters in the archival graphs (trendlines). Keeping a log
of emergency events and alarms, recording informa-
tion from the diagnostic system on the status of the
EHS equipment. Preparation of reports for printing Examples of visualization in the control system
and sharing via e-mail.
Diagnostics. Control of the system operation parame-
ters, power supply, operation of the input-output
modules, calculation of the operating time of each
heating circuit of the EHS, monitoring of the commu-
nication system.
Reference. Providing the AWS operator with all the
necessary background information on the EHS opera-
tion and its components and control actions in the
event of an abnormal situation.

Power and interface switching RS-485 for 40 MS Automatic switching from primary to redundant
modules power supplies
Networking for 247 MS, AS, and AS-xxx-Ex Units Indication and notification of alarms
Protection of incoming and outgoing circuits

Purpose
The main purpose of the ConTrace IPS module is to
provide the ConTrace MS modules with power and
RS-485 communication interface. In addition to the
MS modules, remote temperature measurement modu-
les ConTrace AS and remote temperature measure-
ment units ConTrace AS-xxx-Ex can also be connect-
ed to the ConTrace IPS module. In this way, all
ConTrace devices form a single control system for
electrical heating, ready for connection via the
RS-485 Modbus RTU protocol to an industrial com-
puter or PLC with the installed specialized software
ConTrace.
Thanks to ConTrace IPS modules, the control system
can be extended during operation by adding new
ConTrace MS control modules and ConTrace AS
remote temperature measurement devices.

Description
The ConTrace IPS module, depending on the number ConTrace IPS is supplied with three terminators of the

Purpose
Automatic load switching board (ALSB) is used to re-
connect the load to a source of power by automatical-
ly switching to a second (backup) input when power is
lost at the first (main) input. Normally, the switchboard
is reset automatically when the main source of power
is restored (priority of the first input). The main input
is typically a stationary power mains Un = 380 V, f =
50 Hz. The backup input can be a stationary power
mains or a diesel generator. ALSBs are widely used at Ordering information
