Pig Tracking & Inspection Instruments

Elite Pipeline pigs are used for a number of reasons, but regardless of the reason, knowing where they are in the pipeline is imperative.

Electronic Location Launcher

Powered by dry battery UM-5, it mainly consists of source coil, transmitting circuit, magnetic-inductive materials, and stainless steel shell. Fitted in a pig, the emitter sends out continuous steady signals of low frequency in operation. It has the advantages of long working time, convenient battery installation, signal stability, shock resistance, and high pressure resistance.

  • Continuous working time: >200h
  • Signal receivable distance: >20m
  • Pressure resistance5-10Mpa

Electronic Location Receiver

The receiver consist of a receiving probe, an amplifying and filtering circuit, alarm display system, and a power supply. It composes the electronic tracking system together with the electronic location emitter. The receiver is used to receive low frequency signals transmitted by the emitter in order to locate the pig accurately when it is jammed in pipeline.

  • Location accuracy: ±1m
  • Receiving radius: 10m;
  • Continuous working time: 72h;
  • Effective detecting depth: 6-8m

Intelligent Location Receiver

Intelligent Location Receiver with a built-in MCU, they digitize the signal, analyze and judge the field situations by software, which decreases incorrect report and increases the credibility of the whole equipment.

    • Continuous working time: 72h;
    • Location precision: ±1m
    • Receiving radius: 10m;
    • Effective detect depth: 6-8m

Passage Indicators

The structure features and main technical specifications of passage indicator are similar with the receiver. It is mainly applied in segmental pointed monitor of running pig. When the pig passing monitor spot, the passage indicator can immediately send out a precious alarm signal and remember it so that the hunting scope is significantly shortened when jams happen.

  • Continuous working time: 72h;
  • Corresponding speed: 20m/s;
  • Receiving radius: 10m;

Effective detect depth: 6-8m

Intelligent Passage Indicator

Intelligent Passage Indicators are new generation products of Passage Indicators. With a built-in MCU, they digitize the signal, analyze and judge the field situations by software, which decreases incorrect report as well as increases the credibility. Application feature is to dispense with artificial gain control.

  • Continuous working time: 72h;
  • Corresponding speed: 20m/s;
  • Receiving radius: 10m;
  • Effective detect depth: 6-8m
  • Type: single probe, double probe

Mechanical Explosion-proof Pig Signaler

  • Mechanical Explosion-proof Pig Signalers which mainly consist of mechanical transmission body and clock-control head is the necessary equipment in pigging process. Fixed on the top of the pipe and used to check whether the pig has passed the test point or not, they can direct the swift flow through offering information to the operators by grade two signal source of light, point, sound or special-made clock.

    • Applicable pressure: 0-20MPa;
    • Applicable temperature: -20—80 ℃;
    • Nominal diameter of pipeline: D≥DN80;
    • Conveyance medium: oil, gas, water

On-stream Disassembly Pig Signaler

On-stream Disassembly Pig signalers, which mainly consist of base, pig valve, mechanical body, vent valve, adaptor ring, gauge outfit, and safety template, are important equipments in ball passing process flow. They are fixed on the pipe and used to inspect whether the pig has passed the test point or not. The advantages are acid and alkali proof, corrosion proof, structural explosion-proof, visual and credible indication, and dismountable with pressure which is convenient for maintenance in operation.

    • Applicable pressure: 0-20MPa;
    • Applicable temperature: -20—80 ℃;
    • Nominal diameter of pipeline: D≥DN100
    • Conveyance medium: oil, gas, water

Cable & Pipe Locator

Cable and Pipe Locator consists of a transmitter and a receiver, it can be used to locate trace and depth of the underground cables and metallic pipes, it can also be used to identify the cable from a group of cables.

Pipe Detection Mode:

  • Intelligent Peak Method (Wide): Suitable for active detection.
  • Peak Method:
  • Suitable for passive detection.
  • Narrow Method.
  • Null Method.

Cable Identification Mode:

  • Clamp intelligent identification.
  • Clamp current measurement.
  • Mini sensor identification.

Leakage Detectors of Underground
Metal Pipe and Metal Pipe Detector

Leakage Detectors of Underground Metal Pipe and Metal Pipe Detectors mainly consist of transmitter, receiver, and other accessories, which are special instruments applied to inspect route of underground metal pipe and detect leakage of external anti corrosive coating

  • Working time of launcher: 24h;
  • Detect length: 1-5KM;
  • Detect depth: 10m;
