Horizontal Q345R liquefied gas storage tank, manufacturer's contract, after-sales supply

Description :

　　Whenever it has been openedtankPeople may have this feeling: This thing is too simple! Inside is an empty layer of iron sheet, oh, there are still a few pipes on top! That's actually true, but as a special equipment, its manufacturing process is not as simple as people imagine. Let me take you through its manufacturing process briefly.

　　The step is to cut the material. It is to divide the board into blocks of different sizes and shapes according to the requirements, cut the pipes into long and short sections according to the requirements, and mark the finished materials one by one according to the requirements, and then proceed to the next process.

　　Next is the roll round, also known as the reel. It is to roll the finished sheet metal into a circle on a plate rolling machine, requiring its roundness, edge angle and other indicators to meet the standard requirements.

　　After rolling the circle, longitudinal seam splicing should be carried out. Different storage tanks may require one or multiple cylinder sections, depending on their specific length, and each plate rolled into a cylinder is a cylinder section.

　　All the cylinder sections have been assembled, and the next step is to weld all the cylinder sections on this storage tank together to form a complete cylinder, which is the assembly and circumferential welding of the cylinder body. At this point, even if the cylinder is completed, it is now just a large pipe with two ends connected, unable to hold anything. The next step is to seal both ends of the cylinder, and the component used is called the head. The head is usually made by a head manufacturer specializing in pressing the head, as specialized head pressing equipment is required. The weld seam between the head and the cylinder is also called the circumferential seam. After welding the circumferential seams at both ends, the shell is basically completed. At this point, a hole can be drilled on the shell to accommodate the medium.

　　Only being able to hold things is not enough to meet the requirements. You also need to be able to put things out from inside and operate them simply by turning on a switch. At this point, it is necessary to install different purpose nozzles on the cylinder according to the designed steps, in order to connect valves on the nozzles. The takeover has already been completed in the cutting process. In order to facilitate connection with the valve, it is necessary to first connect the takeover to the flange. This process can be carried out by different teams simultaneously with the shell production. After the completion of the shell and connecting flange assembly, the connecting flange assembly is welded to the predetermined position of the shell, and then the storage tank is basically completed. But in order to ensure the stability and stability of the storage tank, it is also necessary to weld a saddle (horizontal) on it for easy fixation. This complete storage tank has been made into shape.

　　However, storage tanks are a special type of equipment that can contain explosive materials. Once a leak occurs and an explosion occurs, it can cause serious safety accidents. The power of such a large tank can be imagined if it were to explode. So in order to make it just a quiet storage tank serving the people, the country has established a cumbersome standard system and supervision and inspection procedures. All important welds must undergo non-destructive testing before entering the next process. If all tests are qualified, overall post weld heat treatment must be carried out to eliminate residual welding stress. But this is still not reassuring, so it is filled with water for pressure resistance and air tightness tests to verify whether its strength, stiffness, and tightness meet the expected requirements. All of the above important processes must be completed under the supervision of the national supervision and inspection department.

　　After completing all the above steps, the manufacturer shall issue the nameplate, certificate of conformity, and quality certificate of the storage tank, and the inspection department shall issue the inspection certificate and stamp the steel seal on the nameplate. Only then can this storage tank officially serve the people.
