STEEL PIPE JOINT FOR PIPE EXPANDING AND METHOD FOR EXPANDING STEEL PIPE JOINT
PROBLEM TO BE SOLVED: To provide a steel pipe joint for pipe expanding and a method for expanding steel pipe joint which, even if in high pipe expanding rate, rarely causes cracks in jointed surface. SOLUTION: In diffusion connecting for a metal pipe 12e and a metal pipe 14e through connecting surfa...
