| titleOfInvention | Method for producing insulated casing pipes in a continuous production process |
| abstract | The invention relates to a continuous method for producing insulated pipes comprising a medium pipe (3), a casing pipe, a layer of at least one polyurethane between the medium pipe and the casing pipe, and a film tube (5) between the at least one polyurethane and the casing pipe, comprising at least the steps of (A) providing a medium pipe and a film tube, which is continuously formed from a film, in a jaw conveyor, wherein the medium pipe is arranged within the film tube in such a way that an annular gap is formed between the medium pipe and the film tube, (B) injecting a polyurethane system comprising at least one isocyanate component (a) and at least one polyol mixture (b) into the annular gap, (C) foaming and curing the polyurethane system, and (D) applying a layer of at least one thermoplastic plastic to the film tube by means of extrusion in order to form the casing pipe, wherein the injection as per step (B) is performed by means of a multi-nozzle bent according to the radius of the annular gap. |
