Embodiment Construction

[0036] The technical solutions of the present invention will be further described below through specific embodiments.

[0037] A method for manufacturing a cryogenic container, comprising the steps of:

[0038] Step A1: Cut the plates required for the barrel section;

[0039] Step A2: Milling and beveling the two sides of the plate obtained in step A1 to obtain the bevel required for welding, making it easier to weld the plate into a barrel joint, improving production efficiency and the quality of the subsequent formed barrel joint .

[0040] Step A3: rolling the plate processed in step A2 into a cylindrical shape;

[0041] Step A4: welding the longitudinal seam of the tubular plate obtained in step A3 to obtain the tubular section;

[0042] Step A5: Carrying out circle adjustment processing on the cylinder joint obtained in step A4, so that the cylinder joint becomes a regular hollow cylinder, and improves the quality of the cylinder joint;

[0043] Step A6: Use X-rays to...

Abstract

A manufacturing method of a cryogenic container comprises the following steps that step A1, plates required by a shell ring are cut; step A2, groove milling is conducted on the two side edges of the plates obtained in the step A1; step A3, the treated plates in the step A2 are rolled into a cylindrical shape; and step A4, longitudinal seams of the cylindrical plates obtained in the step A3 are welded, and the shell ring is obtained; step A5, the shell ring obtained in the step A4 is subjected to circle checking; step A6, longitudinal seams of the shell ring subjected to circle checking are shot through X rays, and RT flaw detection is conducted; step A7, sealing heads are arranged at the two ends of the shell ring subjected to RT flaw detection in the step A6 in a sleeving mode; and step A8, the sealing heads are welded to the two ends of the shell ring, and thus a liner of the cryogenic container is obtained. According to the manufacturing method of the cryogenic container, the cryogenic container capable of being manufactured through the method is good in quality, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of cryogenic container manufacturing, in particular to a manufacturing method of a cryogenic container. Background technique [0002] In the field of cryogenic technology, cryogenic liquids refer to gases that exist in liquid form below -160°C, such as liquid oxygen, liquid nitrogen, liquid argon, liquid hydrogen, liquid helium, liquid methane and LNG, etc., which are widely used in industrial production, hospitals and in daily life. A cryogenic liquid storage container is usually a double-layer structure composed of an inner tank and an outer shell. There is a vacuum interlayer between the inner tank and the outer shell. The stability of the inner container and the outer shell is ensured by a suitable support structure, and the inner container and the external environment are minimized. The generated heat is conducted to ensure the overall thermal insulation effect of the cryogenic container. However, the low-tempe...
