Replica testing for boiler tubes high temperature steam ...
The long-term experience of research of magnetic fields on boiler and steam tubes has shown presence of steady lines of change of the sign of normal component of magnetic intensity in zones of development of metal damages. This diagnostic parameter (the line =0) was put in the basis of testing techniques of .
