Intelligent Pigging System

Integrated Launching, Receiving & Automated Pipeline Assessment

How the Integrated Solution Works

The process begins like a standard pigging operation but adds a crucial layer of intelligence.

1. Deployment: An intelligent inspection pig (or "smart pig"), equipped with high-resolution sensors such as Magnetic Flux Leakage (MFL) or Ultrasonic Testing (UT), is loaded into the launcher.

2. Automated Journey & Data Collection: Once launched, the smart pig travels through the pipeline. As it moves, its sensors continuously scan the pipe wall, collecting vast amounts of data on metal loss, corrosion, cracks, dents, and other anomalies.

3. Precision Location Tracking: The system incorporates advanced localization technology. By using a combination of odometer wheels on the pig, synchronized GPS timestamps at the surface, and the detection of known features like welds and bends, the system can pinpoint the exact location of every detected defect with remarkable accuracy.

4. Reception & Data Retrieval: Upon completing its run, the pig is captured in the receiver. The collected data is then downloaded from the pig's onboard memory module.

5. Analysis & Reporting: Specialized software processes the raw data to generate detailed reports. These reports provide a clear visualization of the pipeline's condition, mapping out defects by their precise location (distance from the launch point and clock position), severity (e.g., percentage of wall thickness lost), and type.

Pigging Series Equipment

1-The quick opening closure is applicable to the openings of pressure pipelines and pressure vessels , and offers rapid opening and closing functions. It is composed of closure cap ,  clamp ,  pup  joint ,  safety  interlock  mechanism  and open/close mechanism. Our product has introduced foreign advanced technology and advanced design conception to furnish the clipping and opening mechanism with compact and flexible features and reduction of size based on strength assurance. There is no relative rotation between O-ring and sealed area when the closure is closed. Thus the sealing reliability  is  ensured.  The  entire  closing  and  opening process can be completed by one person within 1 minute without special tools involved , so that the labor intension is considerably reduced. This product is especially suitable for  pipeline  cleaner  launching  and  receiving  and  filter equipment , etc.

1A-Clamped type quick opening closure

Clamped  type  quick   opening  closure   includes closure  cap ,  clamp ,  pup  joint ,  safety  interlock mechanism and open/close mechanism. It can realize quick  opened/closed  for  launcher  &  receiver  and filter equipment.

1B-Bandlock type quick opening closure

Bandlock  type  quick  opening  closure  adopts  the limited unit in analysis & design , separated as inner bandlock and outer bandlock quick opening closure. The  construction   of  quick   opening  closure  is divided into vertical and horizontal quick opening types.

1C-Inserted type quick opening closure

Inserted type quick opening closure is composed of closure cap , cylinder flange , and safety interlock mechanism.

2 Pig Launcher And Receiver

Thepigreceiver &launcheris main equipment in the process of pipeline cleaning process of the petroleum , petrochemical and natural gas pipeline  .Its  basic  function  is  to  launch  and receive pigs. Put the pig into it through the rapid opening and closing the quick-opening closure on the receiver & launcher , achieved fast completing cleaning or dredge pipe work , in  order to  improve  the  pipeline  transport capacity , and reduce energy consumption , to ensure  the  safe  operation  of  the  pipeline system.  It divided into normal and intelligent receiver & launcher according to use the type of  pigs  difference ,  it  is  the  main  difference between the barrel length of pig launcher & receiver.

4-Intelligent magnetic leakage detection cleaning pig

The detector with magnet produces a longitudinal magnetic field on the circumference of the tubewall. When the detector is in the tube , if the tube wall without defect , themagnetic coil is inside the tube wall. If the inner wall or the outer wall of the tube is defective , the magnetic force lines will penetrate  out  of  the  tube  wall  to  produce magnetic  leakage(Magnetic  Flux  Leakage-MFL).  The operation of the process as shown below.

The leakage magnetic field is located between the two poles , close t o the probe of the tube wall to pick  up ,  and  produce  the  corresponding  induction  signal ,  the  signal  through  the  filter ,  after amplified processing , recorded on the detector with the memory , and then Playback processing data , to determine its identification.
