Pipeline Gauging Pigs
PetroSan Oilfield Engineering Co. is a leading manufacturer and supplier of high-quality Pipeline Gauging Pigs. Trust us for innovative solutions ensuring your operations run smoothly and efficiently.
Gauging Pigs are specialized pipeline inspection tools used to measure the internal diameter and geometry of pipelines. They are designed to detect and record any changes in the pipeline’s internal dimensions, such as: Internal diameter reductions, Ovality, Bends, Welds, Other geometric anomalies.

Gauging Pig Types:
1. Mechanical Gauging Pigs: Use mechanical arms or fingers to measure pipeline diameter and geometry.
2. Electronic Gauging Pigs: Use electronic sensors, such as ultrasonic or laser sensors, to measure pipeline diameter and geometry.
3. Caliper Gauging Pigs: Use mechanical or electronic calipers to measure pipeline diameter and geometry.
Gauging Pig Components:
1. Sensor Systems: Collect data on pipeline internal dimensions and geometry.
2. Data Loggers: Store data collected by the sensor systems.
3. Propulsion Systems: Move the gauging pig through the pipeline, such as wheels or fins.
Benefits of Gauging Pigs:
1. Improved Pipeline Safety: Detecting changes in pipeline internal dimensions helps prevent pipeline accidents.
2. Reduced Maintenance Costs: Identifying potential issues early on reduces maintenance and repair costs.
3. Increased Efficiency: Gauging pigs can inspect pipelines faster and more accurately than traditional methods.
4. Enhanced Regulatory Compliance: Gauging pigs help pipeline operators meet regulatory requirements and industry standards.
