BOLT INDUCTION HEATING

ROTOR REPAIR SERVICES



+ ONSITE BOLT INDUCTION SERVICES
The Induction Nut Heating System utilizes the
same variable frequency inductive equipment
proven in our Induction Bolt Heating System.
Mannings USA (UK) PLC has delivered the benefits
of induction heating to fasteners without
traditional bolt holes.

The advent of our nut heating process enables a
coil to be adapted to the nut size according to
specifications.
Mannings USA (UK) PLC has
developed a method of rapidly
removing horizontal joint turbine
bolting.

This process utilises an inductor
placed in the bolt or stud.
One of the most recent
applications for induction heating
has been to stress relieve
turbine rotors once they have
been weld repaired.

The conventional method has
been to construct a temporary
furnace around the rotor which
involves considerable time and
expense.

However during heat treatment
of these large rotors they must
be continuously rotated to avoid
the possibility of any bending or
distortion taking place in the
rotor.

The non contact characteristic
of induction makes this ideal for
this purpose since static coils
can be placed around the rotor
to induce heat within it.
A medium frequency inductive field
sets up a low voltage high current
magnetic field within the bolt itself,
causing fast heating, a process
which allows us to rapidly elongate
studs on Turbine components.
