An illustrated view of an exemplary water pipe scale removal device is presented. The water pipe scale removal device includes a cutting head configured to be inserted into a pipe. In addition, the water pipe scale removal device includes a flexible drive cable in rotational communication with the cutting head. The cutting head includes a cylindrical shaft having three separated cutting members. Each separated cutting member includes eight elongated cutting blades arranged concentrically around the cylindrical shaft, while each cutting blade has a side cutting edge and a front cutting edge. The cutting blades are oriented at an acute angle to the central axis of the cylindrical shaft. The device is useful for removing scale buildup from a pipe.

A process for extracting a condensable vapor from a supplied gas, comprising the steps of: i) condensing the condensable vapor by cooling the supplied gas at a condensing surface, such that the supplied gas is divided into at least one condensed fraction and a product gas; while ii) removing the at least one condensed fraction from the condensing surface by mechanical scraping means.
