Active Speed Control Pig (SCP)

Active Speed Control Pig (SCP)

The Active Speed Control Pig is a smart cleaning tool designed to clean high velocity pipelines without costly interruptions in the flow of the line. It will effectively clean pipelines at speeds of 6 to 10 mph, while the natural gas velocity in the pipeline continues to flow at normal rates of 15 to 35 mph.  By using the Speed Control Pig, there is no need to sacrifice reliable gas delivery to the downstream client base or losing transportation revenue by reducing normal gas flow volumes or gas velocity.

The Speed Control Pig is equipped with transmitter for ease of tracking. Sensors can be mounted to monitor changes in operating conditions and gather other useful data points such as:

  • Speed of Tool – up to three odometer data sets
  • Time
  • Distance traveled
  • Inertial data (Impact/Rotation/Pitch/Roll/Yaw/Vibration)
  • Pipeline Pressure
  • Pressure Differential
  • Temperature
  • Vane Opening
  • Gas flow velocity (derived from data)
  • Definition of low spots (derived from data)
  • Battery usage

The ability to collect this data will allow you to  focus inspection resources where they are needed most and maximizing on other benefits such as:

  • Reduced Fuel Costs – a clean pipeline delivers natural gas more efficiently
  • Increased Customer Satisfaction with higher quality gas delivered
  • Reduced Maintenance Costs such as filter replacements
  • Proactive Contaminant & Debris Removal to minimize the breeding ground for corrosion

Inline Services has designed and manufactured the Speed Control Pig with the highest quality components available to withstand and perform within the harsh pipeline environment.

  • Transmitter for ease of tool tracking
  • Dual odometers for accurate distance measurement to points of interest
  • Data logger records pipeline slope, pressure, temperature and tool orientation
  • IMU (inertial measurement unit) detects roll, pitch, yaw, and vibration
  • Variable bypass to keep debris in suspension ahead of tool
  • Pig does not skate over liquids
  • Can be used to enhance chemical cleaning processes
  • Can be used as a towing device
  • Allows for multiple add-ons including brushes and cameras

  • Proven to be a more effective pipeline cleaning and maintenance tool for higher gas flow velocity pipelines
  • Particularly justified for cleaning high gas volume pipelines without having to reduce gas flow
  • Enhances pipeline integrity – having the cleanest possible pipeline avoids less than satisfactory ILI results and the risk of missed or miscalled pipeline anomalies
  • Provides a controlled tool speed platform for add-on Pipeline Evaluation Tool options
  • Provides a platform vehicle for alternative pipeline cleaning methods with either multiple cleaning discs and wire brushes or Prostran cleaning brushes for coated pipe
  • Promotes Safety – provides cleaning tool movement and trapping at safe and manageable speeds.
  • Easy to launch, retrieve and clean
  • Easy to track due to a predictable tool speed, on-board Transmitters, and Magnetic or Geophone tracking response
  • Capable of long distance pipeline runs
  • A tough, rugged and durable pipeline tool with proven survivability
  • Provides a service based alternative to the pipeline operator buying and maintaining cleaning pigs
  • Provides speed control for towing a broad range of maintenance or ILI tools
  • A clean pipeline lowers risk and offers compliance with any regulatory cleaning requirements
  • Peace of mind; a clean pipeline is safe and environmentally friendly
