Abstract

In the cleaning of the inner surface of metal pipes of ring or coil form by means of a liquid cleansing agent, a predetermined quantity of the cleansing agent is first introduced at one end of the pipe, and then a plug, preferably of porous material, such as felt, which fills the pipe cross- sectional area is inserted into the end of the pipe and moved by pressure through the entire length of the pipe, whereby it moves the cleansing agent ahead of itself, and the pressure in the tube is thereafter caused or allowed to dissipate. In this way, the amount of grease present on the inner surface of the tube after treatment can be reduced to less than 0.1 mg grease/dm<2> surface area.
