Einführung in das Pipeline-Molchen

Pipeline operators must clean and inspect pipelines regularly. To achieve this, they use a tool called a Pipeline Inspection Gauge, commonly known as a pig. Pigs travel inside pipelines to perform various tasks. They remove debris, check for damage, and separate different fluids to maintain pipeline integrity.

How the Pigging Process Works

The pigging process begins with insertion. Operators place the pig into a launcher. Then, they use product pressure to push the pig through the pipeline. As the pig moves, it scrapes away buildup and collects valuable data. Finally, the pig exits through a receiver at the end of the pipeline.

Types of Pipeline Inspection Gauges

There are different types of pigs, each serving a specific role.

• Putzschweine remove wax, rust, sludge, and other deposits.
• Inspection pigs, often called intelligent pigs, carry sensors that collect internal pipeline data.

Operators select pigs based on pipeline size, contents, and specific maintenance needs.

Intelligent Pigs and Data Collection

Intelligent pigs provide advanced diagnostics. These pigs use technologies such as magnetic flux leakage or ultrasonic testing to detect corrosion, cracks, or dents. Operators analyze the data to plan preventive maintenance. This helps avoid leaks, ruptures, and costly downtime.

Operational and Environmental Benefits

Pigging also improves pipeline efficiency. Clean pipelines reduce pressure loss and require less energy to transport fluids. In addition, regular pigging supports environmental safety by preventing leaks that could harm land or water sources.

Applications in Different Pipeline Systems

Pigging works in both new and existing pipelines. Operators schedule pigging based on flow rate, product type, and operational conditions. They also monitor pig movement using tracking systems to ensure the pig completes its journey safely and effectively.

Schlussfolgerung

The Pipeline Inspection Gauge plays a vital role in oil and gas operations. It combines cleaning, inspection, and safety into one efficient process. By using pigs, operators maintain pipeline performance, reduce risks, and extend the life of critical infrastructure.
