Pig Launcher And Pig Receiver Systems

Jackwell Engineering LLP Designs And Manufactures Pig Launchers And Pig Receivers For Pipeline Pigging Operations In The Oil & Gas, Petrochemical, Refinery, Chemical, Water, And Process Industries.

Our Pig Launcher And Receiver Systems Are Engineered To Enable The Safe And Efficient insertion, Launching, Receiving, And Removal Of Pipeline Pigs Used For Pipeline Cleaning, Liquid Removal, Product Separation, Batching, Inspection, And Maintenance.

We Offer custom-designed Pig Launcher And Receiver Packages Based On Pipeline Size, Operating Pressure, Temperature, Fluid Characteristics, Pig Type, Project Specifications, And Applicable International Codes And Standards.

What Is A Pig Launcher?

A Pig Launcher, Also Known As A Pig Trap Launcher, Is A Pressure-containing Pipeline Vessel Used To Introduce A Pig Into A Pipeline System.

The Launcher Is Normally Installed At The upstream End Of The Pipeline. The Pig Is Loaded Into The Barrel, The Closure Is Securely Locked, And The Launcher Is Pressurized Before The Pig Is Propelled Into The Pipeline Using The Process Fluid Or Gas Flow.

How A Pig Launcher Works

The Typical Operating Sequence Is:

1. Open & Prepare
   The Launcher Is Isolated And Depressurized Before Opening The Quick-opening Closure.
2. Load The Pig
   The Pipeline Pig Is Inserted Into The Launcher Barrel And Positioned Correctly.
3. Close The Launcher
   The Quick-opening Closure Is Securely Closed And Locked.
4. Pressure Equalization
   The Launcher Is Gradually Pressurized To Equalize Pressure With The Pipeline.
5. Launch The Pig
   The Mainline Valve Is Opened And The Kicker Line Is Operated To Establish Flow Behind The Pig.
6. Pig Travels Through Pipeline
   The Pressure Differential And Pipeline Flow Push The Pig Through The Pipeline.
7. Pig Detection
   Pig Signallers Or Indicators Can Be Used To Confirm Pig Passage.

What Is A Pig Receiver?

A Pig Receiver, Also Known As A Pig Trap Receiver, Is A Pressure-containing Vessel Installed At The downstream End Of A Pipeline To Safely Receive A Pig After It Has Completed Its Journey Through The Pipeline.

The Receiver Is Designed To Decelerate And Capture The Pig While Maintaining Safe Containment Of The Pipeline Fluid.

How A Pig Receiver Works

The Typical Operating Sequence Is:

1. Prepare The Receiver
   The Receiver Is Placed In The Correct Operating Configuration Before The Pig Arrives.
2. Pig Arrival
   The Pig Travels Through The Pipeline And Enters The Receiver.
3. Pig Detection
   A Pig Signaller Confirms The Arrival Of The Pig.
4. Isolate The Receiver
   The Receiver Is Isolated From The Main Pipeline.
5. Depressurize & Drain
   The Receiver Is Safely Depressurized And Drained Or Vented As Required.
6. Open The Closure
   After Confirming Zero Pressure, The Quick-opening Closure Is Opened.
7. Remove The Pig
   The Pig Is Safely Removed From The Receiver Barrel.

Typical Pig Launcher / Receiver Configuration

A Typical System Consists Of:

1. Main Barrel

The Main Barrel Provides The Internal Space Required For Pig Loading, Launching, Or Receiving.

2. Reducer / Cone

A Reducer Or Eccentric Cone Connects The Larger Trap Barrel To The Pipeline Diameter.

3. Quick Opening Closure

The Closure Provides Rapid And Safe Access For Loading Or Removing The Pig.

4. Kicker Line

The Kicker Line Is Used To Control Flow And Create The Pressure Differential Required To Launch Or Receive The Pig.

5. Mainline Connection

The Mainline Connection Allows The Pig Trap To Integrate With The Pipeline System.

6. Vent Connection

Used For Controlled Venting And Depressurization.

7. Drain Connection

Used For Draining Liquids From The Pig Trap.

8. Pressure Gauge / Instrumentation

Provides Pressure Monitoring During Operation.

9. Pig Signaller

Indicates The Passage Or Arrival Of The Pig.

10. Quick Opening Closure Safety System

Provides Operational Safety By Preventing The Closure From Being Opened While The Vessel Remains Pressurized.
