  • Patent number: 10040247
    Abstract: A method for the sterile connection of pipes, consisting of: providing a first and a second pipe; a separating area of the first and second pipes is heated; both pipes are mechanically separated by exerting traction and/or shear force onto the pipes so that both pipes are respectively separated in the heated separating area; after the pipes are separated, a mechanical contact between the end of the first pipe section of the first pipe formed by the separation of the first pipe is established with the end of the first pipe section of the second pipe, formed by the separation of the second pipe, and mechanical contact is established such that the ends of the pipe sections still have, following heating when they come into mechanical contact with each other, a temperature such that they form a material fit connection without additional heating after separation.
