Embodiment 1

[0023] like Figure 1 to Figure 3 As shown, the medium and high pressure refractory metal overall multi-layer wrapping container includes an inner cylinder 1 and a head 2, the outer peripheral side of the inner cylinder 1 is covered with a wrapping laminate 3, and the inner cylinder 1 and the head 2 A transition connection ring 4 is arranged between them. The inner cylinder 1, the head 2 and the transition connection ring 4 are all made of refractory metal materials and the three are welded into one structure. Non-destructive testing is carried out on the weld seam, which can Reach the requirements of the connection strength of the three and the internal corrosion resistance of the equipment; the transitional connection ring 4 effectively solves the strength problem of the transition zone between the head 2 and the inner cylinder 1, and at the same time avoids the stress problem when the edge of the head is welded; the transition The outer peripheral surface and the end surfac...

Embodiment 2

[0029] The structural principle of this embodiment is basically the same as that of Embodiment 1, and the similarities will not be repeated. The only difference lies in the difference in the positioning structure between the transition connecting ring 4 and the wrapping reinforcing ring 5 .

[0030] refer to Figure 4 , in this embodiment, the positioning structure includes connecting ring positioning holes 61 uniformly arranged on the annulus of the transitional connecting ring 4, which can be internally threaded holes, and the annulus of the wrapping reinforcing ring 5 is provided with The reinforcing ring positioning hole 62 matched with the connecting ring positioning hole 61 can also be an internally threaded hole, and a fastening bolt 65 is arranged between the connecting ring positioning hole 61 and the reinforcing ring positioning hole 62, and the structure is simple Reasonable, stable and convenient positioning.

Abstract

The invention relates to the technical field of pressure vessels, in particular to a medium-high pressure refractory metal integrated multilayer wrapped vessel. The medium-high pressure refractory metal integrated multilayer wrapped vessel comprises an inner cylinder and a sealing head; the peripheral side of the inner cylinder is coated with a wrapped laminated plate; a transition connecting ring is arranged between the inner cylinder and the sealing head; the inner cylinder, the sealing head and the transition connecting ring are all made of a refractory metal material and are welded into a whole; a wrapped reinforcement ring is arranged on the peripheral surface and the end surface of the transition connecting ring; a positioning structure is arranged between the transition connecting ring and the wrapped reinforcement ring; each wrapped reinforcement ring is welded with the wrapped laminated plate. According to the medium-high pressure refractory metal integrated multilayer wrapped vessel, the overall structural design is reasonable; the installation operation is convenient; the problem about connecting of the sealing head and the cylinder of the wrapped vessel is effectively solved; the cost of a colour material is reduced; the problem that core equipment of a refractory metal explosive composite plate device often leaks under the working conditions that the metal temperature difference is great and the born pressure is rigorous.

Description

technical field [0001] The invention relates to the technical field of pressure vessels, in particular to a medium-high pressure refractory metal (titanium, zirconium, tantalum, etc.) integral multi-layer wrapping container. Background technique [0002] In order to improve the pressure bearing capacity of the overall wrapping container, the spherical head design is usually used in the medium and high pressure integral wrapping container, but in GB150.1~150.4-2011, there is no medium and high pressure refractory metal (titanium, zirconium, tantalum, etc.) The specific connection structure between the head of the multi-layer wrapped container and the cylinder. At the same time, in acetic acid, acetic anhydride and other project devices, such as acetic acid and acetic anhydride carbonylation reactor (zirconium steel composite plate equipment) after a period of operation, the equipment often leaks, and the effect of leakage repair is not ideal. If pure zirconium is used to mak...
