Abstract
PURPOSE: To prevent the occurrence of gas leakage of a pipe used under high pressure and high temperature by making the pipe comprise a metal pipe body with its one end open and a seal portion for sealing the other end without a seam between the pipe body and the seal portion. CONSTITUTION: One end of a pipe body 1 made of a difficultly melted metal such as molybdenum or the like is open, and the other end is sealed by a seal portion 2. Further, there is no seam between the open pipe body 1 and the seal portion 2. Consequently, no crack or gas leakage occurs even if the pipe is used under high pressure and high temperature for a long period of time.
