- Major Barrel: Provides the main chamber for accommodating the pipeline pig before launching.
- Minor Barrel: Connects the launcher assembly to the pipeline and accommodates the required pig launching arrangement.
- Reducer Section: Connects barrel sections of different diameters and provides the required transition.
- Quick Opening Closure (QOC): Provides access for pig loading, unloading and internal inspection.
- Vent and Drain Connections: Support pressure release, liquid drainage and maintenance procedures according to the approved operating design.
- Pipeline Connections and Flanges: Connect the launcher to the pipeline and associated station equipment.
- Instrumentation Connections: Accommodate pressure gauges, pig signalers and other specified instruments.
The detailed component arrangement, nozzle orientation, barrel length and closure configuration are finalized according to approved engineering drawings.

3. Design Considerations and Configuration
Pig Launcher design requires coordination between the pipeline system, pig specifications and operating procedures.
Key engineering considerations include:
Pig Dimensions and Barrel Length
The internal diameter and effective barrel length must accommodate the intended pig dimensions and loading arrangement. For intelligent inspection pigs, overall length, handling clearance and equipment access should be considered during design.
Design Pressure and Operating Conditions
Design pressure, operating pressure, temperature and fluid service determine the pressure-containing design requirements and material selection. Final parameters are established in accordance with the applicable design code and project specification.
Quick Opening Closure Arrangement
The closure type, opening direction, locking mechanism and safety interlock arrangement should be selected according to the equipment design and operating requirements. The closure must be compatible with the barrel dimensions and specified pressure rating.
Pipeline Connections and Installation
Flange standards, nozzle positions, vent and drain connections, supports and installation orientation should be coordinated with the station layout and pipeline design.
Pigging System Compatibility
The launcher configuration should be checked against the intended pig type and the complete pigging procedure. Foam, cup, brush and intelligent inspection pigs may be considered, subject to dimensional and operational compatibility.
4.Typical Applications
RKSfluid Pig Launchers are used in pipeline systems where controlled pig introduction is required for cleaning, dewatering, inspection and maintenance.
Typical applications include:
- Oil and gas transmission pipelines
- Natural gas gathering and trunk pipelines
- Crude oil and refined petroleum transportation systems
- Compressor and metering stations
- Oil and gas terminals and storage facilities
- Onshore and offshore pipeline systems
- Industrial process pipelines
The final equipment configuration depends on pipeline service conditions, pigging frequency, pipeline layout and project operating procedures.
