Abstract

PURPOSE: To obtain easily and efficiently the titled trunk without using any cutting machine of complicate numerical control by making a cylindrical body with bending work of a slab and, after the longitudinal seam is welded, by shaping helical grooves on the internal, external or both surfaces of the cylindrical body and by forming into a noncylindrical body.
CONSTITUTION: For a blanket vessel of fusion reactors, there is a pressure vessel 1 made of stainless steel in which pressure is balanced to the neighbouring vessel. This is of square cross section with a roundness at each corner 2, having helical channels 3 for cooling material between double vessel trunks. In order to manufacture this vessel trunks, rectangular slabs 10 made of stainless steel of desired dimensions are worked by bending and a cylindrical body 11 with a longitudinal seam 11a is formed. Then the seam 11a is subjected to perfectly penetration butt welding to make a cylindrical body 12. After helical grooves 13 are formed on the internal surface by cutting or plastic working, the cylindrical body 12 is roughly formed with a press or a roll to make a cylindrical body 14 of an elliptic cross section. Further, the body 14 is finish-formed by explosion or hydraulic forming method to produce a squre cross section cylindrical body 16 with a roundness at each corner 15.
