Abstract

PURPOSE:To manufacture the body of a cylindrical tube joint simply and easily by forming parts to be expanded at both ends of a cylindrical tube separately by forging and joining them into a body by welding. CONSTITUTION:Parts 3, 3' to be expanded which are to be provided at both ends of the cylindrical main part 2 of a cylindrical tube joint are made if needed by sizing a material 5 of stainless tube worked to a specified size, expanding the end part of the pipe using a die 6 and a punch 7 and thickened using other die and punch to form a forged expanded part. Two such expanded parts 3, 3' are joined to a straight cylindrical main part 2 by welding 4, 4'. A conventional stainless tube cut to a specified length is used as the straight cylindrical main part 2.
