SOLUTION: The surface of a first base material 6 is coated with a first cathodic protective coating layer 7 having cathodic protective action to form the surface-treated alloy 5 having low thermal expansion coefficient. The first base material 6 is composed of a low thermal expansion coefficient alloy 10 having a compressive residual stress layer 9 on the surface. The first cathodic protective coating layer 7 is composed of inorganic or organic zinc-rich paint, and the inorganic or organic zinc-rich paint consists of zinc dust 11 and resin 13. The compressive residual stress layer 9 is formed by blasting treatment such as sand blasting, and ruggedness for improving the adhesion of the inorganic or organic zinc-rich paint can be formed at the surface of the first base material 6 by the blasting treatment.

摘要： PROBLEM TO BE SOLVED: To provide a low-temperature material treating facility which reasonably connects a piping 1 made of Fe-Ni-based low-thermal-expansion-coefficient alloy with a pipe coupling or an apparatus made of stainless-steel. SOLUTION: An extension straight pipe portion 3 made of a same material is provided for a piping 1 made of Fe-Ni-based low-thermal-expansion-coefficient alloy and for a coupling (bent pipe 6, branch pipe 7) or an apparatus (valve 2 or others) made of stainless-steel pipe, and this low-thermal-expansion- coefficient alloy made piping is welded with this extension straight pipe portion 3. The length L (mm) of the straight pipe portion 3 is longer than 0.6 (R×t) , where R is outer radius (mm) of the extension straight pipe portion, and (t) is its thickness (mm). Because different material welding is a welding between the straight pipes, thermal stress distribution can be predicted and stress analysis and piping design become easy.

摘要： PROBLEM TO BE SOLVED: To constitute a carrier pipe without having any loop pipe or suppressing the number of loop pipes as less as possible by forming the carrier pipe of a low thermal expansion part composed of Fe-Ni based low thermal expansion coefficient alloy. SOLUTION: A pipe 1 carrying extremely low temperature liquefied gas is constituted of a low thermal expansion part formed of Fe-Ni based low thermal expansion coefficient alloy called invar alloy. The thermal expansion coefficient of the Fe-Ni based low thermal expansion coefficient alloy is approximately 1/10 compared with austenite based stainless steel used for a conventional pipe and the deformation of the carrier pipe formed of using the invar alloy caused by the expansion/contraction can be extremely minimized compared with the conventional pipe so that, when the both ends of the pipe 1 are fixed without providing any loop pipe, the thermal stress generated in the pipe 1 never exceeds the tolerable stress. This constitution can eliminate an overhang part in a part from one end 2 to the other end 3.
