Abstract
A method for producing a, in particular thin-walled, pipe conduit element with a surface structure reinforcing the pipe conduit element is proposed wherein the pipe conduit element continuously passes by at least one embossing element guided about the periphery of the jacket thereof and the surface structure is embossed onto the jacket of the pipe conduit element by the embossing element using pure mechanical pressure. For embossing the surface structure onto the pipe conduit element, an arrangement of preferably several embossing elements, in particular balls or rollers are used which are distributed about the periphery of the pipe conduit element jacket. The invention also concerns a device for producing a surface structured pipe conduit element using a guidance having embossing elements and which can be rotated about the periphery of the jacket of a pipe conduit element continuously supplied to the device.
