Underground pipe locator

Specifications

Function:detect the position and depth of the underground metal pipelines.
Principle:electromagnetic induction
High accuracy

Function:

It can not only exactly detect the position, trend and depth of the underground metal pipelines or cable without digging the soil, but also find the leak poit of the anti-corrosion steel pipeline and fix the trouble point of the cable.

Application:

 Widely used in petroleum,chemical,natural gas and pipeline transport departments.Used in construction exploring departments such as urban gas,water supply,electric or communication etc.It also used for detecting the pipeline anti-corrosion and overhauling the cable trouble points,which provides the practical and effective ensures for the underground pipelines safety running.

Principle:

Pipelines locating principle:According to the principle of electromagnetic induction,determine the position,trend and depth of underground pipeline through surveying its magnetic field.
Leak detecting principle:Through launching electromagnetic wave signal to underground metal pipelines,the corrosion point will be short circuit with the earth when the insulating anticorrosive coating is corroded,at the leak point there will be round circuit ejecting leak signal to the ground.And on the right up side of the leak point.the radiation signal is the strongest.According to this principle,we can precisely find out the corrosive point.

 Characteristics:

Adopting all-digital single machinery technology and humanity design.Its functions and using scopes exceed the same type detector.

Pipeline-in current measuring function,which provides judging basis for fine/bad standard of the pipeline anti-corrosion coating.

Special function for anti-corrosion coatings leak detecting,A model shelf method and body capacitance methods,which apply for different environment.

Multi-frequency launching way and strong anti-interference ability.which apply for complicated pipeline detect.

Signal exerting model has two ways,which are induction way and direct-link way,wuiting for different situation.

Varied responding models:double-wires circle peak-value method,single-wire circle peak-value method and zero-value method.

Varied detect way:directly read method;80% method;70% method and 50% method.

Big frequency emitting,direct-link method can emit 3-5m each time.
