Abstract: A pipe section includes a support layer consisting of a metal base material. The support layer has an inner surface, at least two pipe section ends each having an end region, and an intermediate region. Each end region of the inner surface of the support layer has a first coating consisting of a first metal coating material. The first coating is welded to the support layer. The intermediate region of the inner surface of the support layer has a second coating consisting of a second metal coating material. The second coating is sprayed onto the support layer using a thermal spraying process and has a second thickness. The second thickness is less than or equal to 2500 μm.
