A pipe segment, pipe assembly, method for producing pipe segment and pipe assembly, and use of pipe assembly

The invention relates to a pipe section (100), comprising:-a carrier layer (110) made of a metal substrate (111), the carrier layer (110) having an inner surface (114), at least two pipe section ends (116), each of which has an end region (117) and an intermediate region (118); -a first coating layer (120) consisting of a first metal coating material (121) at each of the end regions (117) of the inner surface (114) of the carrier layer (110), the first coating layer (120) being welded to the carrier layer (110); and a second coating layer (130) located in the intermediate region (118) of the inner surface (114) of the carrier layer (110), consisting of a second metal coating material (131), the second coating layer (130) being sprayed onto the carrier layer (110) by a thermal spraying process and having a second thickness; wherein the inner surface (114) of the carrier layer (110) has a roughness Ra greater than or equal to 0.2 [mu] m, preferably a roughness Ra greater than or equal to 0.4 [mu] m, particularl
