The interlayer pipeline is arranged in an interlayer space between the inner container and the outer shell and used for connecting the inner pipeline and the outer pipeline. Because the volume of the interlayer space is limited, the structure at the joint of the interlayer pipeline and the internal pipeline is inconvenient to manufacture and easily causes the contact of the interlayer pipeline and the shell seal head, so that the shell seal head is brittle broken, the connection with the external pipeline is limited by the space of the valve box, the effective nondestructive detection is difficult to realize, and the product quality is ensured. Therefore, it is necessary to design a sandwich pipeline structure which is easier to manufacture and check and ensures the safe use of the tank, so as to improve the batch manufacturing efficiency of the tank and ensure the product quality.
The connection between the interlayer pipeline and the internal pipeline of the existing tank is provided with a straight-through pipe joint edge, and the end part of the interlayer pipeline needs to be bent during manufacturing and then is subjected to socket welding with the straight-through pipe joint edge. The other end of the interlayer pipeline is in butt welding with an external pipeline. When the interlayer pipeline is manufactured, the large-diameter pipeline is limited by the volume of the interlayer space, the large bending radius enables the distance between the pipeline and the shell end socket to be relatively short, the pipeline is easy to be in direct contact with the shell end socket, and the shell end socket is brittle and broken when serious, so that vacuum failure is caused. The manufacture of smaller bending radius is difficult to realize, and the manufacturing quality is difficult to ensure completely. Meanwhile, the joint of the interlayer pipeline and the external pipeline adopts butt welding, and is difficult to carry out nondestructive testing due to the limitation of the valve box and the external pipeline, so that mass production is not facilitated.
