A Little Wisdom Helps You Become Smarter !In the video, A worker prepares a pipeline pig (cleaning ball) by wrapping it in a white plastic bag.
He holds the bag-covered pig against a concrete pump pipe, supporting it by hand as the system activates.
Why the plastic bag? It creates an initial air-tight seal and lubricates entry, helping the pig slide into the pipe smoothly.
Why hold it in place? Manual control prevents the pig from being instantly sucked in at dangerous speeds (preventing pipe abrasion or equipment jolt).
This method is a low-pressure startup technique for safe pipeline cleaning operations.
