Which Pigs Are Used for Pipeline Gauging? https://youtu.be/kcXg5MqXRwg For pipeline gauging, specifically in the oil and gas industry, a type of pig called a “pipeline inspection gauge” or “pipeline pig” is typically used. These pigs are used for various purposes, including cleaning, inspecting, and maintaining pipelines. Pipeline pigs are cylindrical devices that are inserted into the pipeline and propelled by…
What is the typical testing cycle for Smart Pipeline Inspection Gauges (PIGs)?
What is the typical testing cycle for Smart Pipeline Inspection Gauges (PIGs)? https://youtu.be/7tFq_72EnWQ Usually, the testing cycle is once or twice a year. The more frequent the inspection cycle, the more it can ensure the safety and reliability of the pipeline. For high-pressure and high flow pipelines, such as oil and gas pipelines or chemical pipelines, the detection cycle will…
How does Cleaning Pipeline Inspection Gauges (PIGs) work?
How does Cleaning Pipeline Inspection Gauges (PIGs) work? https://youtu.be/s-BPYZm0k6o 1.Before inspecting the pipeline, please check the equipment for cleaning and disinfecting the PIG. This will ensure that no more pollutants are introduced during PIG cleaning. 2. Place the PIG on the cleaning workstation and connect it to the cleaning device. The cleaning device usually consists of a sprayer and nozzle…
How does Inspection Pipeline Inspection Gauges (PIG) perform hydraulic propulsion?
How does Inspection Pipeline Inspection Gauges (PIG) perform hydraulic propulsion? https://youtu.be/iU2NvyYTyRo The following are the general steps for hydraulic propulsion: 1. Install the PIG inlet on the pipeline. The entry port is usually a snap ring, magnetic rotating rod, or other device. This will ensure that the PIG can move smoothly in the pipeline and ensure the accuracy of the…
What is Inspection Pipeline Inspection Gauges (PIG) hydraulic propulsion?
What is Inspection Pipeline Inspection Gauges (PIG) hydraulic propulsion? https://youtu.be/cdTZC7Twqe4 Hydraulic propulsion is a common PIG propulsion method that is suitable for most pipeline types. The high pressure of the liquid can make it relatively easy for PIG to pass through curves and turns within the pipeline, and tightly connect with the interior of the pipeline with a smaller bending…
What is the maximum pigging velocity?
What is the maximum pigging velocity? https://youtu.be/cdTZC7Twqe4 The maximum pigging velocity, also known as the maximum allowable velocity, is the highest speed at which a pig can safely travel inside a pipeline without causing excessive wear or damage to the pig or the pipeline itself. Generally, the maximum pigging velocity is determined by considering factors such as: Pig Design: Different…
What is intelligent pig inspection of pipelines?
What is intelligent pig inspection of pipelines? https://youtu.be/qqOcbXpGOFQ Intelligent pig inspection, also known as inline inspection or smart pigging, is a method used to assess the condition of pipelines. Intelligent pigs are equipped with various sensors and measurement devices that collect data as they travel inside the pipeline. These sensors capture information about the pipeline’s dimensions, anomalies, wall thickness, corrosion,…
What role does battery safety in pipeline inspection instruments (PIG) play for pipelines?
What role does battery safety in pipeline inspection instruments (PIG) play for pipelines? https://youtu.be/whkv9HXcZfI The safety of the battery in the pipeline inspection instrument (PIG) plays an important role in the pipeline, which is mainly reflected in the following aspects: Prevention of safety accidents: Since the pipeline detector needs to work in the pipeline, if the battery is not safe…
What are the internal battery needs of pipeline inspection instruments (PIGs)?
What are the internal battery needs of pipeline inspection instruments (PIGs)? https://youtu.be/H1OuK2bT2yk The battery in the pipeline inspection instrument (PIG) needs to meet the following basic requirements: High energy density: The battery of the detector needs to have high energy density to ensure long-term use.
