Chemical pressure vessel manufacturing and forming process

Abstract

The invention relates to a chemical pressure vessel manufacturing and forming process. The chemical pressure vessel manufacturing and forming process mainly comprises the various procedures of material preparation, rolling operation, pairing operation, welding operation, detection operation and the like; and pressure vessel assembling equipment used in the chemical pressure vessel manufacturing and forming process comprises a bottom plate, a lifting device, a clamping device and an abutting device. The chemical pressure vessel manufacturing and forming process can solve the problems existing in butt joint assembly of an existing chemical pressure vessel that A, during the butt joint assembly of the traditional chemical pressure vessel, the stable butt joint operation cannot be performed on a pressure vessel barrel and a pressure vessel end socket, and the butt joint dislocation often occurs during the butt joint of the pressure vessel barrel and the pressure vessel end socket, so that the butt joint quality of the pressure vessel barrel and the pressure vessel end socket is reduced; and B, existing chemical pressure vessel butt joint assembling equipment cannot stably clamp and position the pressure vessel barrel, so that the pressure vessel assembling stability is affected, and the pressure vessel assembling efficiency is reduced.

Description

technical field [0001] The invention relates to the technical field of tank body production and manufacturing, in particular to a manufacturing and molding process for chemical pressure vessels. Background technique [0002] A pressure vessel is a closed container that can withstand pressure. The use of pressure vessels is extremely wide, and it has an important position and role in many sectors such as industry, civil, military, and many fields of scientific research. Among them, it is most used in the chemical industry and petrochemical industry. In the field of chemical industry, it is mainly used for heat transfer, mass transfer, reaction and other processes, as well as storage and transportation of pressurized gas or liquefied gas. During the production of chemical pressure vessels, it needs to be docked and assembled. [0003] However, the following problems exist in the butt joint assembly of the existing chemical pressure vessels. Butt dislocation often occurs when...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the butt joint assembly of the existing chemical pressure vessels. Butt dislocation often occurs when the head is docked, which reduces the quality of the butt joint between the pressure vessel cylinder and the pressure vessel head; b The existing chemical pressure vessel docking assembly equipment cannot perform stable clamping and positioning operations on the pressure vessel cylinder, which affects the pressure. Stability during vessel assembly reduces the efficiency of pressure vessel assembly
