This rigid pipe producing line is composed of the follwing components as described below.

The operator places the raw material manually in the unreeling basket (not applicable for a possible online - production).

By using a conveyor belt, the raw material passes the cutting station, where the raw material is being cut of the lenght and there after transported on to the conveyor belt of winding station. The calculated lenght dependent on the weight to, diameter ind isolation strength. The conveyor belt continues to transport the raw material, with the right length, to the winding station.

In the winding station the raw material is being wound around a mandrel by an envelope roller, which seizes the beginning of the material. The mandrel gives the shell inside diameter. Thereby the conveyor belt of the winding station changes ist lining downwards, depending on the pipe inside diameter and the setting of the layers to be winded.

After the winding procedure, the mandrel with isolation is being placed via transfer station to the hot air heating station. In the meantime the winding station receives a new mandrel via the loading station and the winding procedure starts again.

In the hot air heating station, the raw material, which has been wound around the mandrel, is being dried and hardenend. After this procedure the mandrel with isolation will be transported to the grinding station. Depending to the requested number of items (cycle time), the quantity of the hot air heaters can be varied. In this case there can be reached, with a shell size of 153mm and an isolation strength of 30mm, a quantity up to 4 pieces per minute.

The grinding station (with a driven grinding roll) is working on the pipe outside diameter to an exact manufacture measurement of +/- 0,1 mm.

The further transport, of the mandrel including the isolation to the dismantle station, is porcessed by a transfer station. During this procedure the finished pipe is separated from the mandrel. The mandrel without isolation is being transported to the mandrel reconduction carriage via a transfer station. The mandrel is always in constant circulation.

The grinded isolation is being transported to the cutting station via carriage, in which the isolation is cut reciprocally to a final length of the pipe. After this procedure the pipe is being placed by the carriage to the slitting station.

In the slitting station the pipe is slit over the entire length and transported to the packing station.
