Pigging is a crucial process in maintaining and operating pipelines across various industries, including oil and gas, water treatment, and food production. In this process, a device, known as a “pig,” is sent through a pipeline to perform cleaning, inspection, or maintenance tasks. The types of pigging can be broadly categorized based on the pigging machine, launchers and receivers, pipeline pigging products, and pigging launcher systems used. Let us take a closer look at them.

The Different Types of Pigging Machines

When it comes to a pigging machine, then you can choose from several categories based on their functions:

• Cleaning Pigs: These pigs are designed to remove pipeline debris, buildup, and other contaminants. They come in various forms, including foam, brush, and scraper pigs, each suited to different cleaning needs.
• Inspection Pigs: Also known as intelligent pigs or smart pigs, these devices are equipped with sensors and data collection tools to inspect pipelines’ internal condition. They can detect corrosion, cracks, and other structural issues, providing crucial data for preventive maintenance.
• Sealing Pigs: These pigs are used to separate different products within the same pipeline or clear the residual product line. They ensure the integrity and purity of the transported materials.

Various Types of Pigging Launcher and Receiver

The pigging launcher and receiver are essential components of a pigging system. Here are the different types:

• Pigging Launcher: This device introduces the pig into the pipeline. It is designed to handle pigs of various sizes and shapes, ensuring they enter the pipeline without damage.
• Pigging Receiver: Located at the endpoint of the pigging route, the receiver safely extracts the pig from the pipeline. It is engineered to handle the retrieved pig and any debris or data collected during its journey.

What are the Other Pipeline Pigging Products?

There are numerous pipeline-pigging products customized for different applications:

• Foam Pigs: These pigs are made from polyurethane foam. They are versatile and can navigate pipelines with tight bends and irregularities. They are commonly used for basic cleaning and drying.
• Brush Pigs: Equipped with brushes or abrasive pads, these pigs provide more intensive cleaning, removing more inflexible deposits from the pipeline walls.
• Magnetic Pigs: These pigs use magnets to collect ferrous debris from the pipeline, ensuring a clean and smooth interior surface.
• Bi-Directional Pigs: Designed to move in both directions, these pigs are helpful for pipelines that require frequent cleaning or inspection without continuous flow.

The Range of Pigging Launcher Systems to Choose From

A pigging launcher system is a specialized setup designed to facilitate the pigging process:

• Automated Launcher Systems: These systems automate the pigging process, allowing for precise control and reduced manual intervention. They are ideal for large-scale and high-frequency pigging operations.
• Manual Launcher Systems: Simpler and more cost-effective, these systems require manual operation but are suitable for smaller-scale pigging tasks.

Pigging systems can be made up of various machines, launchers, receivers, and products tailored to specific needs. Choose from the different types of pigging available at the Equip Up Store maintain your pipelines efficiently, ensuring safety and a better performance.
