‘’ ISO 9001: 2008 CERTIFIED COMPANY IN HEAT TREATMENT ‘’

HEAT TREATMENT

Jasscan Inspection is equipped with state-of-art heat treatment facilities and established itself as “One Stop”

heat treatment solutions provider for wide range of industries including engineering, marine and oil & gas.

Heat treatment is a process to achieve the required physical and mechanical properties for which the part will

be used. Heat treatment is a metallurgical application for relieving the stress after welding, hardening and

softening the material according to requirement for its end use. There are many types of heat treatment

processes that are in practice namely annealing, tempering, hardening, normalizing, post weld heat treatment

and preheating etc.

We carry out many complex heat treating schedules to optimize an alloy's mechanical properties such as

increasing the strength, increasing the machinability, improving toughness and stress relieving.

TRANSFORMATOR UNIT

50kVA TRANSFORMER POWER UNIT

This unit provides a 60volt output supply for powering

various type/sizes of low voltage-60V heating element. It

consists of an air natural 3 phase transformer contained

in a wheeled robust sheet case and controls the

secondary output in 6 channel mode. The output

channels are controlled by means of energy regulators

and temperature controllers but provision is made for

external control from any suitable controller or setter

programmer.

Each channel has its own auto/manual switch so any

combination of channels can be operated either auto or

manual. The Power unit is protected against over current

or over temperature condition.
