Abstract (en)

Boiler has many round pipes through which heating medium flows and head pieces (3) at both ends of the round pipes, by means of which the pipes are technically flow-connected to each other. To create a boiler with a sealing connection between the pipes on one hand and the head pieces on the other, each round pipe has an adjustable extension (5) on the head piece side running around the inside of the pipe, pointing in the direction of the respective head piece. Head pieces each have many pipe connections (4) of circular diameter. The end of each connection facing the pipe has an enlarged inner diameter (DISe). A reduced outer diameter (DARr) of each round pipe corresponds to the enlarged inner diameter of the attached pipe connection.
