    1514606 Pressure vessel SOC CHIMIQUE DES CHARBONNAGES and NATIONAL FORGE CO 15 Oct 1976 [28 Oct 1975] 42830/76 Heading B1X A pressure vessel in combination with a temperature control jacket disposed around the pressure vessel comprises at least one ring 12 of weldable material disposed around the pressure vessel 10, the jacket 18 being welded to the ring which is thereby an integral part of the jacket and means 16 for radially compressing the ring. The compressing means may be wire wrapped under tension around the ring. By this means, the jacket can be welded to the pressure vessel where the material of the vessel is not suitable for welding.

    专利说明:

    The invention relates to welding, in particular to methods for manufacturing high pressure chambers, and can be used in the manufacture of reactors in the chemical, power and other industries. . Known tanks operating at relatively low pressure, which are usually made from welded sheets. Welding such a shell is not difficult, since this assembly is assembled from a steel grade suitable for welding l. However, chambers in which the internal pressure exceeds 350 kg / cm usually have walls of considerable thickness (more than 7.5 cm), and special high-strength steels that are poorly weldable serve as materials for these walls. The closest to the proposed technical essence is a method of manufacturing a high pressure chamber, in which the chamber body is made of high strength steel with at least one flange on which the thermostatic shell is mounted. However, the material of the tanks is poorly welded, it is necessary to carry out significant preparatory operations, such as metal welding, as well as preliminary, strictly controlled heating to obtain a high specific temperature. After performing this welding, it is also necessary to perform a significant heat treatment of the weld. Despite all the measures taken, the weld has a pronounced tendency to crack, and cracks, although they manifest only as local defects, can grow and penetrate into the main body of the reservoir, causing it to fail prematurely. The purpose of the invention is to simplify the manufacturing technology and improve the quality of the product. For THAT, the thermo-regulating shell is mounted on the flange of the case by welding with, at least, one sleeve of metal-welded shell of the material, which is fixed to the plumber by means of a compression ring, or the sleeve is deposited on the flange, or fixed on the flange by winding on metal tape. FIG. 1 shows the shell obtained by the proposed method; on
    FIG. 2 shows section A-A in FIG. one; in fig. 3 - fastening the sleeve by precipitation; in fig. 4 - fastening of the sleeve by winding the tape.
    The sleeve 1 cHa4aj; ia is mounted on the flange 2. Then a ring 3 is placed on it with tension, which is made of a high-strength material such as special steel used to make the wall 4 of the chamber.
    The ring 3 is placed on the sleeve 1 with tension, thus ensuring its radial compression. Therefore, the sleeve 1 is pressed against the outer surface of the flange 2, thereby creating a tight connection between them. The flange 2 and the sleeve 1 are subjected to compressive stress, while the ring 3 is under tensile stress. This is important from the point of view of the stresses arising in the sleeve 1 when the chamber is in operation or is being tested. In this case, the high pressure created in the chamber tends to stretch the sleeve along the radius. The radial expansion is restrained in the area of the flange 2 by the fitted ring 3. Since this ring is made of high quality alloy, it resists well the tensile stresses of the chamber. At the same time, the sleeve 1 of conventional steel, amenable to welding, does not experience noticeable tensile stresses caused by radial expansion, since the ring 3 prevents this expansion T1. Thus, the pressing sleeve 1 is mainly affected by compressive forces. This stress distribution is characteristic if I compare it with the stress distribution in the case of the removal of ring 3, when only sleeve 1 is tightly attached to flange 2.
    Thermal-control shell 5 is welded to sleeve 1 by seams 6. If welding cracks appear when thermostatic jacket 5 is fixed on sleeve 1, the integrity of the chamber wall is not impaired.
    FIG. Figure 3 shows an embodiment of the method in which the central part at the periphery of the flange 2 is removed and forms an annular space 7, thereby reducing the bearing surface between the flange 2 and the sleeve 1, which leads to an increase in the contact pressure between the sleeve and the remaining parts of the flange. This design makes it easy to ensure tightness due to the high pressures between the elements. The sleeve is attached to the flange - or draft, or by winding on it a metal tape. The camera, manufactured by the proposed method, has high indicators during operation.
