Pig Launchers & Receivers

What is a Pig Launcher / Receiver?

Pigging in the maintenance of pipelines refers to the practice of using Pipeline Inspection Gauges or 'pigs' to perform various operations on a pipeline without stopping the flow of the product in the pipeline. 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. 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 pig receiver trap - the 'pig catcher'.

Pigging has been used for many years to clean larger diameter pipelines in the oil industry. Today, however, the use of smaller diameter pigging systems is now increasing in many continuous and batch process plants as plant operators search for increased efficiencies.

Accelerated Process Systems designs and fabricates pig launchers & pig receivers that provide a safe and effective means of inserting and removing pipeline pigs to and from pipelines. Our engineers design pig launchers and pig receivers to meet the specific requirements of a pipeline. Our in-house design, engineering, fabrication and testing capability is used to produce all types of pig and sphere launching and receiving systems.

The pig launchers and pig receivers we fabricate range from simple barrel pig launchers and receivers through to complete skid mounted units with associated equipment including actuated valves, quick opening closures, instrumentation, pig signallers and control systems.
