Stopple (2025)

: A plugging machine is mounted onto the fitting. It pushes a "plugging head" into the pipe to create a seal and stop the flow.

Without this technology, every minor repair would require a total system shutdown. That means: stopple

A (or STOPPLE®, a trademarked term by T.D. Williamson ) is a specialized device used to temporarily block or isolate a section of a pipeline while it remains under pressure. Think of it like a temporary valve you can install anywhere on a pipe without needing an existing shut-off point. The Stopple Process: How It Works : A plugging machine is mounted onto the fitting

: Workers can now safely repair the isolated section. Once finished, the plugging head is withdrawn, and a "completion plug" is used to seal the fitting permanently. Why Stoppling Matters That means: A (or STOPPLE®, a trademarked term by T

: First, a specialized fitting (like a split tee) is welded to the pipe. A hot tapping machine then drills a hole through the pipe wall without any product leaking out.

: Critical services like gas or water stay online.

Stoppling isn't as simple as sticking a cork in a bottle. It's a high-stakes engineering feat that involves several precise steps:
