This measure is particularly useful for the application of u-shaped strands to the side of the U-shaped connection of the legs recommended. she is but not required. Where this seems beneficial can such extensions also on the outflow side the tube bundle must be attached.
- the material from which the strands exist depends on the operating conditions, especially according to the medium to which the strands are exposed and according to the intended operating temperature.
- the expert chooses that based on his knowledge suitable material. Be exemplary without so that a limitation is made to some of the in Question coming materials called: metal, plastic, Rubber, wood, ceramics, carbon. From the plastics are delayed for media that are less aggressive Polypropylene (PP) or polyvinyl chloride (PVC) are used.
- PP Polypropylene
- PVC polyvinyl chloride
- fluorine-containing Polymers such as polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), tetrafluoroethylene-perfluoropropylene copolymer (FEP) or copolymers of tetrafluoroethylene with Perfluoroalkyl vinyl ether (PFA) used.

- PVDF polyvinylidene fluoride
- FEP tetrafluoroethylene-perfluoropropylene copolymer
- PFA Perfluoroalkyl vinyl ether
- the outer diameter of the strand is preferably one third to eight tenths of the inside diameter of the heat exchanger tube surrounding it. These proportions have opted for aggressive heat exchangers chemical media in which the exchanger tubes are made of Graphite and the strands were made of plastic, proven. However, the invention is not based on this Dimensional relationships limited. If necessary, this can be done be deviated.
- the strand For cases where the strand is inside the pipe must be arranged in a stable position, it is recommended that Support the strand in places on the smooth inner wall of the pipe. In general this can be achieved be that the strand by known means such as Webs on the inner wall of the exchanger tube is supported. When choosing and arranging the support elements should only be taken care of be that the flow in the annular gap is not essential is affected. According to a preferred approach a support is reached when the strand Pipe interspersed in a spiral shape.
- This spiral shape arises with flexible material by for example as a corrugated pipe strand Inserting it into the tube twisted around its axis or it after insertion on the opposite end of the tube, or tube plate locked, then twisted, doing something compresses and then at the other end of the tube, or Also defines the tube sheet. That way it happens to support the strand on the inner surface of the Tube.
