What is Pipeline Pigging?
Pipeline pigging is the process of using a specialized device called a “pig” to clean, inspect, or maintain a pipeline. These pipeline pigs are inserted into the pipeline and propelled through by the flow of the product or by using external sources such as compressed air or liquid. Pipeline pigging is an essential part of routine maintenance for pipelines to prevent build-up of debris and corrosion, enhance efficiency and performance, and extend the life of the pipeline.
Types of Pipeline Pigs
Inline Services offers a wide range of pipeline pigs for various applications, including general cleaning, batching, product recovery, and corrosion mitigation. Our pigs are designed to be suitable for all pipeline sizes and configurations, including multi-diameter, bi-directional, long distance, and high-risk offshore pipelines.
Some of our popular pig types include:
- Utility Pigs: These pipeline pigs are used for general pipeline cleaning and can remove debris, sediment, and other contaminants from the interior of the pipeline.
- Batching Pigs: Batching pipeline pigs are designed to optimize product flow by moving products from one location to another. They are particularly useful in pipelines with multiple products or when switching between different types of products.
- Product Recovery Pigs: These pigs are used to recover valuable products that may be left in the pipeline after a batch run. They can efficiently collect and transfer this product to a designated location for reuse or disposal.
- Gel Pigs: Gel pigs are used for cleaning pipelines with complex bends, restrictions, or multi-diameter sections. The gel-like material allows the pig to easily navigate through tight spaces and remove debris without causing damage.
- Corrosion Control Pigs: These pigs are designed with specialized coatings and materials to help prevent corrosion in pipelines. They can also be used for applying inhibitors or removing scale and buildup that contribute to corrosion.
