Abstract: Dissimilar piping joint arrangement, including a first pipe section and a second pipe section and a dissimilar piping joint between the pipe sections, the first and second consecutive pipe sections being made of first and second metallic materials respectively with different material behavior and properties. An improved lifetime and extended applicability is achieved in that said dissimilar piping joint is a coupling joint, said first pipe section made of said first metallic material is provided at one end with a first coupling made of said first metallic material, said second pipe section made of said second metallic material is provided at one end with a second coupling made of said second metallic material, and the first coupling and the second coupling are bolted together, whereby a first seal is established by direct metallic contact between the front faces of the first coupling and the second coupling.
