Temperature Control Industrial Induction Heating Equipment For Oil
& Gas Industry
HOW INDUCTION HEATING WORKS:
Frequency conversion electromagnetic induction heating or induction
heating for short is a method for heating metal materials by
converting power frequency power supply into that of specific range
based on the principle of electromagnetic induction. It is mainly
applicable to the metal hot working, heat treatment, welding and
melting.
Basic components of induction heating system include induction
coil, AC power source and work pieces. Induction coil can be
fabricated into different shapes as per different heated objects.
The coil is connected with the power source providing alternating
current for coil. The alternating current possessed by the coil can
create a alternating magnetic field passing through the work pieces
to produce eddy flow as required by heating.
In a basic induction heating setup shown in Right Figure, a solid
state RF power supply sends an AC current through an inductor
(often a copper coil),and the part to be heated (the workpiece) is
placed inside the inductor. The inductor serves as the transformer
primary and the part to be heated becomes a short circuit
secondary. When a metal part is placed within the inductor and
enters the magnetic field, circulating eddy currents are induced
within the part.
As shown in follwoing Figure , these eddy currents flow against the
electrical resistivity of the metal, generating precise and
localized heat without any direct contact between the part and the
inductor. This heating occurs with both magnetic and non-magnetic
parts, and is often referred to as the "Joule effect", referring to
Joule's first law – a scientific formula expressing the
relationship between heat produced by electrical current passed
through a conductor.
Secondarily, additional heat is produced within magnetic parts
through hysteresis – internal friction that is created when
magnetic parts pass through the inductor. Magnetic materials
naturally offer electrical resistance to the rapidly changing
magnetic fields within the inductor. This resistance produces
internal friction which in turn produces heat.
In the process of heating the material, there is therefore no
contact between the inductor and the part, and neither are there
any combustion gases. The material to be heated can be located in a
setting isolated from the power supply; submerged in a liquid,
covered by isolated substances, in gaseous atmospheres or even in a
vacuum.

APPLICATIONS IN OIL AND GAS INDUSTRY:
Oil and natural gas suppliers rely on induction heating equipment
for many different production processes:
- Soldering of rock drilling tools
- Forming pipe ends for bottles and cylinders
- Heating the ends of sucker rods
THE ADVANTAGES OF THE INDUCTION HEATING:
Innovative induction heating technology offers many advantages for
the oil and gas industry:
- Energy saving: it has such features as uniform heating (it is applicable to adjust
the spacing of the induction coil to ensure the appropriate
temperature as required by each part of work piece), fast warming
and limited oxic horizon, and can guard against any waste after
annealing.
- Reduced processing time: it can be started to perform heating operation on condition that
water and power supply is available. the minimum rate of heating is
less than 1 second (rate of heating is available for adjustment and
control)
- Temperature control:it is applicable to control the temperature for heating work pieces
as per the preset heating time, and thereby control the heating
temperature at a certain technical point.
- Control and localized heating
- Possibility of integration into assembly lines
- No physical contact: With induction, the part to be heated never comes into direct
contact with a flame or other heating element; the heat is induced
within the part itself by alternating electrical current.
- Improved working environment : Induction heating systems do not burn traditional fossil fuels;
induction is a clean, non-polluting process which will help protect
the environment. An induction system improves working conditions
for your employees by eliminating smoke, waste heat, noxious
emissions and loud noise. Heating is safe and efficient with no
open flame to endanger the operator or obscure the process.
Non-conductive materials are not affected and can be located in
close proximity to the heating zone without damage.
