For long-distance pipelines, if the inner wall becomes scaled (for example, in a carbon steel pipeline with a diameter of DN250 and a transmission distance of 1000 meters, the scaling on the inner wall is quite severe). It is white scale that has already affected the transfer of the medium; how should this scaling be removed?
It’s the ball passage diameter! Get a serving tube and a receiving tube. . .
Upon inspection: the inner wall of the pipe is covered with white, hard scale. The ball-passing method doesn’t seem to work!

How can such a long pipe be pickled? I’m worried!
Seal both ends, use a pump to create circulation, and strike the pipes with a rubber hammer in the middle. . .
Doing this is really a bit difficult!
