1. PIPELINE CRACK DETECTOR
ABSTRACT :
Leakage detection system ranges from simple , visual line waking and checking to
complex arrangement of hardware and software. No one method is universally applicable
and operating requirement detection which method is most cost and effective .The aim of
the paper is to review the basic technique of leakage detection are currently in use . The
advantage and disadvantage are discussed applicable are outline. The review begin with
the summary of leaks and implication of the failure to detect them. The bulk of this paper
deal with modern computers based technique. Basic flow equation are covered and the
on-line dynamic calculation required are list together with the impute data required to
enable the monitoring is to be accomplished with the minimum of down time. .The latest
system are capable of resolving down to 1% maximum rated flow of response.
Intentional damage unfurtanely are in increased and the pipe line carrying
flammable or high value products make ideal target.
