Waveguide Methods for AE Online
Testing of Several Cryogenic Vertical
Double-Wall Tanks
Yanting Xu, Yadong Wang, and Jianyong Zheng
Abstract Three kinds of cryogenic and atmospheric vertical double-wall storage
tank structures are studied in this paper. Some external structural parts of a storage
tank or specially designed auxiliary components are used as the waveguide rods
of AE on-line detection. The waveguide effect is verified by transmitting analog
signals between adjacent waveguide poles. Some tanks have been inspected by means
of these waveguide methods. The results show that these waveguide methods can
basically meet the requirements of AE online detection of these kinds of tanks.
Therefore, the technical problems of AE on-line detection of such tanks have been
finally solved.
30.1 Introduction
In recent years, AE technology has been widely used in the on-line inspection of
single-wall vertical atmospheric storage tanks in the normal temperature range, and
good results has been achieved. It not only solves the safety inspection problem of
storage tanks, but also saves the overhaul time and enormous cost of open inspection
for enterprises [1, 2]. For double-wall cryogenic storage tanks, AE detection is needed
for the inner tank, but AE sensors are usually difficult to be mounted directly on the
inner tank wall because of the double-wall tank structure feature, and then AE online detection cannot be directly implemented. Therefore, through the research and
field investigation of several typical types of double-wall cryogenic tank structures,
we designed special acoustic wave guide device or used some structures of the tank
to assist AE on-line detection of these tanks. These practices have proved that the
technical problems of AE on-line detection of these storage tanks have been well
solved.
