Shengli SL-5088PCM
comprehensive detection and assessment system for the outer anti-corrosive
coating conditions of buried pipelines is designed by Jiangsu Shengli specially
to provide instructions and assistance for the piping industry. It’s applied to
the corrosion and protection of petroleum, natural gas, urban gas and underground
water pipelines. However, due to the absence of early detection and diagnosis
before pipe network overhaul, it was impossible to duly find the hidden danger
in the pipes which were not perforated but whose anti-corrosive and insulating
coating was damaged, which was a cause for the repeated perforating after
repair of buried pipelines. The aging, friability, peeling, and falling of
pipeline protective coating will lead to corrosion and perforation, and then to
leakage, causing immeasurable losses.
Shengli SL-5088PCM
can test the buried pipelines without excavation in order to determine and to assess
the damage conditions of the outer anti-corrosive coating of buried pipelines,
and can conduct precise location and depth investigation of the pipelines,
which was unattainable in non-excavation cases before. That detection
technology not only works as a test and acceptance means for newly built pipes,
but also can regularly monitor the operating pipes. To test the conditions of
the protective coating of buried pipelines and to replace and repair them as
required, extending the life time of pipes, can save lots of maintenance and
reconstruction costs. It’s crucial to ensure the proper operation of pipelines.

foreign ones, only half the weight at the same power.
• Easy operation by only one person
• The receiver can measure and display current without
connection to pipes.
• The use of artificial neural network identification technology
reduces false indication, thus to minimize unnecessary excavation.
• Locating and depth investigation of pipe routes, and
assessment of damage conditions of anti-corrosive coating

Shengli SL-5088PCM
comprehensive detection and assessment system for buried pipeline outer
anti-corrosive coating- working principle: the instrument consists of
transmitter and receiver. The transmitter is an independent 0.1A-3A output
equipment of detection signals, while the handheld receiver is used for tracing
of piping routes, precise location of damage points and current measurement. The
current intensity on the pipes attenuates as the distance increases. With the
same pipe diameter, pipe material, and soil environment, the better the
insulation between anti-corrosive coating and earth is, the less the current
loss and the attenuation are. Otherwise, in case of the anti-corrosive coating
damage, e.g. aging, falling, etc., the worse the insulation is, the larger the
current loss and the attenuation are.
Shengli SL-5088PCM
adopts the first-class neural network identification technology in the world to
quickly determine the size and direction of the damage points on the
anti-corrosive coating, solving the problems encountered by foreign
counterparts which are slow in detection and have high requirements for
earthing, consequently becoming one of the advanced detection instruments in
the world. That system is the patented product of Jiangsu Shengli Detector Co.,
Ltd., China.
