Dear All

in preheating?
Can it be replaced by some other method?

You mean pre heating or PWHT. Normally pre heating can be performed by Butane gas, this tempreature will vary from 20 deg,C to 100 deg.c and  PWHT  can be performed by using thermocouples using electric resistance, tempreature will be more than 595 deg C to 615 deg. C  for P1 material.
