What is the difference between pig launcher and pig receiver?
What is the difference between pig launcher and pig receiver?
PIG launchers are located where a PIG is to be sent into the pipeline. Likewise, PIG receivers are placed where the PIG is to be removed from the pipeline. You will find launchers and receivers all along a pipeline.
What are pig launchers and receivers?
In simplest terms the PIG launchers and PIG receivers are the sections of the pipeline which allow the PIG to enter and exit the pipeline. They are generally funnel, Y-shaped sections of the pipe which can be pressurized or depressurized and then safely opened to insert or remove PIGs.
What is pig in pig launcher?
A pig launcher is a device which uses a pressurized container to shoot a cleaning device (“pig”) through the pipeline to perform a variety of functions including cleaning, monitoring, and maintaining of the pipe. Pig Launcher and Receiver.
What does pig tool do?
Gauging, separation and cleaning pigs A “pig” is a tool that is sent down a pipeline and propelled by the pressure of the product flow in the pipeline itself. There are four main uses for pigs: Physical separation between different fluids flowing through the pipeline. Internal cleaning of pipelines.
What is launcher and receiver?
A Launcher is located at the upstream end of the pipeline to launch the Pig into the pipeline. A Receiver is located at the downstream end of the pipeline to remove the Pig from the pipeline. The design of the Launcher and Receiver will depend on the Pig and pipeline design conditions.
How does a pig receiver work?
This is accomplished by inserting the pig into a Pig Launcher – a funnel shaped Y section in the pipeline. The launcher is then closed and the pressure of the product in the pipeline is used to push it along down the pipe until it reaches the receiving trap – the ‘pig catcher’.
What is scraper receiver?
Pig Launchers/Receivers, also known as Scraper Traps, are generally located at terminal points and at compressor stations along the pipeline and provide a safe and efficient means of inserting and removing various types of pipeline pigs.
Is pig still used?
Yes, it is used by our data science and data engineering orgs. It is being used to build big data workflows (pipelines) for ETL and analytics. It provides easy and better alternatives to writing Java map-reduce code.
Why is it called a pig launcher?
Pigs get their name from the squealing sound they make while traveling through a pipeline. These operations include but are not limited to cleaning and inspection of the pipeline. This is accomplished by inserting the pig into a Pig Launcher – a funnel shaped Y section in the pipeline.
