The invention relates to a method for producing a polymer-enhanced pipeline element, in particular of a fire extinguishing installation, and to a pipeline element and a pipeline system of a fire extinguishing installation. It is proposed according to the invention to provide a first a first and a second hollow body, to align in each case one encircling edge surface of the hollow bodies with one another, to weld the two hollow bodies to one another along the encircling edge surfaces such that an encircling weld seam is generated which has a root extending on the inside of the pipeline element, and to apply a polymer-based layer to the inside of the pipeline element, wherein the polymer-based layer completely covers the inside of the pipe element and the root of the weld seam.

Method for producing a polymer-improved pipe element and pipe element and pipe system comprising same

The invention relates to a method for producing a pipeline of a fire extinguishing installation. The method includes providing a first hollow body and a second hollow body, positioning the hollow bodies relative to one another in a welding zone such that the connection of the hollow bodies can be performed in the welding zone, positioning a collecting container within the first and/or second hollow body in the region of the welding zone, welding the first hollow body to the second hollow body in the welding zone such that the pipeline element is obtained, wherein a fully encircling weld seam is generated which has a root extending on the inside of the pipeline element; and collecting, by the collecting container, weld spatter that occurs on the inside of the pipeline element during the welding process.

Method for producing a pipe element, particularly a pipe element of a fire-extinguishing facility, pipe element and pipe system comprising same

The invention relates to a method for producing a number of pipes () with a predetermined pipe diameter. The method includes feeding multiple pipe parts () with the predetermined pipe diameter to a welding station (), aligning in each case a first pipe part () and a second pipe part () coaxially with respect to one another and axially adjacent to one another, welding the pipe parts () by means of a fully encircling weld seam () to form a pipe run (), conveying the pipe run () to a cutting station () in a machine direction (A) downstream of the welding station (), and cutting off the number of pipes () in a respectively designated length from the pipe run ().
