Problems solved by technology

[0003] Existing pressure vessels generally have a cylindrical structure. This type of pressure vessel is formed by rolling a plate, and then welding the ends of the plate, and then welding steel plates at both ends to form a container; however, the existing Pressure vessels have high requirements on the welding of welding parts. A small welding error often causes the pressure vessel to not be used normally, and welding defects are not easy to observe. Often, the sealing and pressure resistance tests are performed after all welding is completed. Not only It is laborious and laborious, and the production cost is high

Embodiment Construction

[0028] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] like figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 Shown, a kind of manufacturing method of pressure vessel, this method comprises the following steps:

[0030] S1, using a cutting machine to cut the plate into a plate shape;

[0031] S2, placing the plate obtained in S1 into a spiral structure in a plate rolling machine;

[0032] S3, the head and tail of the plate made in S2 are welded together by submerged arc welding; submerged arc welding has better welding quality;

[0033] S4, welding and sealing the two ends of the pressure vessel obtained in S3 with steel plates;

[0034] S5, transporting the pressure vessel prepared in S4 to the next process;

[0035]The plate rolling machine adopted in this method includes a fi...

Abstract

The invention relates to the technical field of pressure vessel manufacturing, in particular to a manufacturing method of pressure vessels. The manufacturing method comprises the following steps: S1,cutting a plate material into a plate by a plate cutting machine; S2, placing the plate obtained in the step S1 into a plate rolling machine and reeling the plate to be in a spiral structure; S3, welding the head and tail of the plate made in the step S2 together by submerged arc welding; S4, welding and sealing the two ends of a pressure vessel manufactured in the step S3 by steel plates; and S5,transporting the pressure vessel produced in the step S4 to the next process. The method is used for welding with the submerged arc welding with better welding quality, and can avoid welding defectsand greatly improve the yield of pressure vessels.

Description

technical field [0001] The invention relates to the technical field of pressure vessel manufacturing, in particular to a method for manufacturing a pressure vessel. Background technique [0002] A pressure vessel is a well-sealed tank structure that can withstand a certain pressure. Pressure vessels are commonly used in chemical production processes. [0003] Existing pressure vessels generally have a cylindrical structure. This type of pressure vessel is formed by rolling a plate, and then welding the ends of the plate, and then welding steel plates at both ends to form a container; however, the existing Pressure vessels have high requirements on the welding of welding parts. A small welding error often causes the pressure vessel to not be used normally, and welding defects are not easy to observe. Often, the sealing and pressure resistance tests are performed after all welding is completed. Not only It is laborious and laborious, and the production cost is higher. Conte...
