What is the Difference Between Pig Launcher and Pig Receiver?

In the oil and gas industry, pipeline maintenance is of utmost importance to ensure the efficient and safe transportation of various products. One crucial aspect of pipeline maintenance is the use of pipeline pigs, which are specialized devices used for cleaning, inspecting, and maintaining pipelines. These pigs are launched and received through specific equipment known as pig launchers and pig receivers. While both serve the same purpose, they have distinct functions and features. In this article, we will explore the difference between pig launchers and pig receivers.

Pig Launcher: A Closer Look.

A pig launcher, as the name suggests, is a device used to launch pigs into a pipeline. It is typically located at the beginning of the pipeline system. The primary purpose of a pig launcher is to propel the pig through the pipeline by using a combination of pressure and flow. The launcher is equipped with a closure door that can be opened to enable the pig to enter the pipeline. It also contains a quick opening closure, which provides easy access for loading and unloading the pig.

The pig launcher is designed to accommodate the launching process safely. It includes safety features such as relief valves, pressure gauges, and isolation valves to control and monitor the pressure buildup during the launch. These safety mechanisms ensure the protection of the pipeline, equipment, and personnel involved in the launching operation.

Pig Receiver: An Overview.

On the other end of the pipeline system, we find the pig receiver. This equipment is responsible for receiving the pig after it has traveled through the pipeline. The receiver is designed to safely extract the pig from the pipeline without any damage to the pig or the receiver itself. Similar to the pig launcher, the receiver also consists of a closure door and a quick opening closure for easy access to the pipeline.

The pig receiver is equipped with various instrumentation devices to monitor and control the pressure and flow during the pig retrieval process. It also includes isolation valves and safety features, such as pressure gauges and relief valves, to prevent any potential damage from excessive pressure buildup.

The Key Differences.

Now that we have a better understanding of pig launchers and pig receivers, let's summarize the key differences between the two:

1. Location - Pig launchers are located at the beginning of the pipeline system, while pig receivers are situated at the end of the pipeline.

2. Function - Pig launchers are used to inject the pig into the pipeline, whereas pig receivers are used to retrieve the pig from the pipeline.

3. Design - Both the pig launcher and pig receiver have closure doors and quick opening closures, but their internal components and safety features may vary according to their specific functions.

In conclusion, pig launchers and pig receivers play crucial roles in pipeline maintenance by facilitating the launching and retrieval of pigs. While they share some similarities in terms of design and functionality, their locations and primary purposes differ. It is essential to have a thorough understanding of these devices to ensure the smooth operation and maintenance of pipelines.
