[0002] Firefighting is a crucial part of the LNG storage and gasification process. The installation of fixed fire sprinkler devices for LNG storage tanks is the top priority of tank safety. According to the design specifications, an annular fire sprinkler pipe needs to be installed on the top and upper part of the tank. Due to the high vertical storage tank, the installation of the fire sprinkler ring pipe is very difficult. Most of them are hoisted by scaffolding or hanging basket, and then the riser ring pipe is welded, and finally cleaned and repainted. The construction is difficult, there are many welding points, and the later repainting also affects the appearance and the cycle is long. The most important thing is that LNG storage tanks are special equipment pressure vessels. The pressure vessel certification and inspection have been completed before leaving the factory. In the later process of fire sprinkler installation, electric welding operations can easily cause damage to the outer wall of the tank. The repair of special equipment pressure vessels needs to be returned to the factory and re-certified. In the process of welding the fixed riser and sprinkler coil from top to bottom, the pipe bracket needs to be cleaned and repainted, which increases the workload of high-altitude work.

[0003] After the tank is welded and installed, each welding position needs to be inspected. The vertical tank is relatively high, and the fixed fire sprinkler device is distributed on the tank top head and the upper part of the tank wall, with 4 to 5 circles, a long cycle, and more high-altitude operations. Therefore, it is urgent to reduce the installation and construction cost of the vertical tank fire sprinkler device and shorten the construction period. Utility Model Content
