Description
【発明の詳細な説明】 本発明は円筒圧力容器の製作方法に関する。[Detailed description of the invention] The present invention relates to a method for manufacturing a cylindrical pressure vessel.
第１図に示すものは円筒圧力容器の一例であって、容器

接して製作している。Conventionally, the container body (1) was made as follows. That is, as shown in Fig. 2, relatively small steel plates (4) are curved, and each of the curved steel plates (4) is lined up one by one as shown in Fig. 3 to form a ring and welded, and the curved steel plates (4) are placed on top of the ring. It is manufactured by stacking (4) and welding.

手間がかかるという問題がある。This conventional manufacturing method does not involve welding the curved steel plates (4) together, which is a so-called circumferential joint.
Since the external fittings (stiffener ring, nozzle, etc.) and internal fittings (tray support ring, nozzle, etc.) are attached after the body (1) is manufactured, there is a problem in that it takes time and effort to attach them.

は屋内作業が司能である。Therefore, the present invention provides a method for manufacturing a cylindrical pressure vessel that solves such problems, and is characterized by forming a panel by welding the side edges of a plurality of rectangular copper plates to each other, The panel is curved so that its edges are arcuate, a plurality of each curved panel is connected to form a cylinder, and the bent sides of each curved panel are welded together to form the container body. The head and tail parts are welded to the upper and lower surfaces of the body. According to this method, the side edges of the strip-shaped steel plates are vertically joined together, which is conventionally popular. Eliminate the familiar nine-circle joint,
By automatically welding products, productivity and quality can be improved. Further, after attaching the outer liquid crystal and the inner liquid crystal to the spring μ by downward welding, a cylinder can be formed, and their attachment is easy. In addition, since it involves forming panels and connecting the panels to form a cylinder, even if the diameter of the cylinder exceeds the building dimensions, work can be carried out indoors up to the step of forming the cylinder.

First, the strip-shaped steel plates (6) shown in Fig. 4 (alK) are lined up as shown in Fig. 4 (bl), and their side edges (6A) are brought into contact with each other. Form the panel (7) by welding the adjacent side edges (6A) downward with an automatic welding machine (in the case of rad steel, perform overlay welding of the stainless steel part in a downward position), then the same figure (cl The spring /L/ (7
) with a predetermined radius of curvature so that its end edge (7A) has an arc shape, and then, as shown in Fig. 5, the curved spring 1v (7) is placed on the base (8). At the same time, the panel (7) is attached to the base (
8), and attach an external stiffener ring (10, etc.) to the outer peripheral surface of the spring/l/ (7) by downward welding to prevent distortion and deformation.Next, remove the rope body (9). hand,
Turn over the spring/L/(7) and attach the internal liquid crystal, such as the tray support ring aυ, to the inner peripheral surface of the panel (7) by downward welding as shown in FIG.
