[0002] At present, conventional chemical container products (such as Figure 1 (As shown) Before the hydraulic pressure test process is carried out, the large-diameter pipes on the spherical heads at both ends are designed to be open structures. It is necessary to install and weld hydraulic pressure test end covers on the large-diameter pipes at both ends of the chemical container before the hydraulic pressure test process can be carried out. After the chemical container product completes the hydraulic pressure test, it is also necessary to cut off the hydraulic pressure test end covers originally installed and welded at the port positions at both ends of the chemical container, and re-process the end margins and bevels at both ends. The use of this manufacturing method leads to a long manufacturing cycle for chemical products, and for chemical container products with open structures, it is also necessary to equip them with many hydraulic pressure test end covers of corresponding specifications, which significantly increases the product manufacturing cost and is not conducive to large-scale production in the workshop.

[0029] like Figure 4 As shown, the inner locating ring 1-5 is an annular structure with a circular hole 1-5-3 at its center for mating with the mandrel of hydraulic jack 1-2. The end surface of the inner locating ring 1-5 is a conical slope 1-5-2. The inner locating ring 1-5 is connected to the mandrel of hydraulic jack 1-2 via a short countersunk screw 1-7. Screw holes 1-5-1 that mate with the short countersunk screw 1-7 are located at corresponding positions on the inner locating ring 1-5 and hydraulic jack 1-2. The circular ring 1-3 is welded to the mandrel of hydraulic jack 1-2.
