Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.
The manual valve is a valve operated by the handle and the hand wheel, and is a commonly used valve on the equipment pipeline.
Valves are the most common equipment in chemical companies. It seems easy to install valves, but if they are not implemented in accordance with the re...

Pipeline pigging systems play a critical role in maintaining the safety, efficiency, and long-term reliability of oil, gas, and industrial pipeline networks. Among the key components of any pigging operation, pig launchers and pig receivers are essential equipment designed for pipeline cleaning, dewatering, inspection, and operational maintenance.
As global pipeline infrastructure continues to expand across oil & gas transmission, refinery systems, natural gas facilities, and industrial process plants, modern pigging systems are increasingly required to operate under high pressure, harsh environments, and demanding operational conditions.
RKSfluid provides customized pig launcher and pig receiver systems engineered for onshore and offshore pipeline applications, offering reliable solutions for safe and efficient pigging operations.
What Is Pig Launcher and Pig Receiver？
A pig launcher is a pressure vessel used to safely insert a pipeline pig into a pressurized pipeline system. The pig is then propelled through the pipeline by the flow of the process medium.
A pig receiver is installed at the downstream end of the pipeline to safely capture and remove the pig after the pigging operation is completed.
Together, pig launcher and receiver systems form the core equipment of a complete pipeline pigging system.
These systems are widely used for:
Why Pigging Systems Are Important in Pipeline Operations
Over time, pipelines may accumulate:
Without regular pigging operations, these contaminants can reduce flow efficiency, increase pressure loss, accelerate corrosion, and create operational risks.
Pigging systems help pipeline operators:
For long-distance transmission pipelines and high-pressure systems, pigging operations are considered an essential part of routine maintenance management.
How Pig Launcher & Receiver Systems Work
During operation, the pig is loaded into the launcher barrel through a quick opening closure.
After the launcher is sealed and pressurized, the pipeline medium drives the pig through the pipeline. As the pig travels, it performs cleaning, separation, or inspection functions depending on the pig type used.
At the receiving end, the pig enters the pig receiver, where it is isolated, depressurized, and safely removed.
Modern pigging systems allow pigging operations to be performed without shutting down the pipeline, significantly improving operational efficiency and reducing maintenance downtime.
Main Components of a Pigging System
A typical pig launcher and receiver system includes:
RKSfluid pigging systems are designed for safe operation, easy maintenance, and long-term service reliability under demanding industrial conditions.
Applications of Pig Launcher & Receiver Systems
