Launchers

A Launcher is a device or system used to initiate, propel, or guide an object orpayload into motion, often over a significant distance or into a new operational phase. The term "launcher" is widely used across different industries, with varied applications:

10 FAQs of Launchers

What is a launcher used for in pipelines?
To insert pipeline inspection tools (pigs) for cleaning, dewatering, or inspecting the pipeline's interior.
How do missile launchers work?
They use mechanical, hydraulic, or explosive energy to propel missiles toward a target, either manually or remotely controlled.
What is the difference between a pig launcher and receiver?
The launcher inserts the pig into the pipeline, while the receiver collects it at the end of its journey.
Are launchers reusable?
Yes, most launcher systems (both mechanical and pipeline) are designed for repeated use with proper maintenance.
What are the safety precautions when operating a launcher?
Follow standard operating procedures, pressure checks, isolation protocols, and ensure all personnel are clear before launch.
Can a launcher be automated?
Yes, modern launchers can be fully automated with remote operation, monitoring, and data feedback systems.
What materials are launchers made from?
Usually high-grade carbon steel, stainless steel, or alloy materials to withstand pressure, heat, and corrosion.
What standards apply to pig launchers?
Standards like ASME B31.3, API 1104, and NACE MR0175 are typically followed.
How is a launcher maintained?
Through routine inspection, seal replacement, valve checking, and corrosion protection.
What sizes are available?
Pipeline launchers range from 2” to 48” diameter or more, depending on the pipeline size.
