Thermal Process
In thermal tube cleaning the layer or deposit is dried through a heating whereby it flakes off due to its embrittlement and is then discharged, either by the conveying medium or a rinsing liquid. Depending on the required temperature, the heating can be either a parallel tube heating or an induction heating. This process is an off-line process. Occasionally it is also used for the sterilization of tubes in the pharmaceutical or food industry. A diameter range cannot be indicated here because this method can be applied for certain processes only; a technical limitation of the heating is given only by the materials and the required amount of heat.

Famous quotes containing the word process:
“The toddler’s wish to please ... is a powerful aid in helping the child to develop a social awareness and, eventually, a moral conscience. The child’s love for the parent is so strong that it causes him to change his behavior: to refrain from hitting and biting, to share toys with a peer, to become toilet trained. This wish for approval is the parent’s most reliable ally in the process of socializing the child.”
—Alicia F. Lieberman (20th century)
