Construction technology of embedded reinforcing structure for large-orifice pipe of container

Abstract

The invention relates to a construction technology of an embedded reinforcing structure for a large-orifice pipe of a container. Application of the construction technology is limited due to the fact that conventional manufacturing and heating processing, welding quality control, heat treatment equipment and warping preventing process of the embedded reinforcing structure used in refining reactors or reproducers are complicated. The construction technology includes the steps of determining blanking length of an embedded reinforcing plates and a parent plate; arranging and disposing the embedded reinforcing plate and the parent plate; arranging and disposing the embedded reinforcing plate and the parent plate; welding divided parts of the embedded reinforcing plate, welding a pipe into an orifice of the embedded reinforcing plate for the pipe, and finally performing bulk heat treatment for a reinforcing plate assembly by means of furnace heat treatment. An arc plate is fixedly welded horizontally on the inner side of the embedded reinforcing plate to prevent radian changes thereof, steel tubes longitudinally penetrate through the divided plates along an axial line to prevent the embedded reinforcing plate from deforming axially. By improving quality of thick plate welding and controlling of deformation of the thick plate, assembling and heat treatment tooling is optimized, the deformation after the embedded reinforcing plate assembly welding and heat treatment is controlled within an allowable range of design, and manufacturing quality of the embedded reinforcing structure is guaranteed.

Description

technical field [0001] The invention relates to an embedded reinforcing structure for shells such as reactors, regenerators, and large storage tanks of oil refining equipment in the petrochemical industry, and in particular to a construction process for the embedded reinforcing structure of large openings for connecting pipes in containers. Background technique [0002] Embedded reinforcement structures are widely used in large-scale equipment such as reactors and regenerators of refinery units in the petrochemical industry. Traditional reinforcement structures are used in reactors and regenerators of refinery units. Since the reinforcement plate and the shell are two layers, Due to the stress, it is easy to cause cracks in the lining of the connecting pipe with large openings. In severe cases, the device is forced to stop production. Reinforcement plate thickness, manufacturing and heat treatment processes are complex, welding quality control, heat treatment tooling and de...
