Is it necessary to install a safety valve on the water cut tank of a spherical tank?
Thread Content
Spherical tanks are pressure vessels and must be equipped with safety valves. Many liquefied hydrocarbon spheres are also equipped with water separation tanks. So, do these water separation tanks need to be fitted with safety valves?
It depends on the design pressure…………
The operating pressure of the spherical tank is 0.5–2.1 MPa, with a higher design pressure.
Spherical tanks are pressure vessels, and safety valves must be installed
The water cut tank beneath the bottom of our spherical tank is equipped with a safety valve.
It should be necessary; when it’s not clear whether to use it or not, then use it – it’s always good to have an extra layer of protection
A safety valve is needed to ensure the safety of the water cut tank.
I don’t remember where I read that for containers with the same pressure source, a safety valve can be installed on only one of the containers. The pressure source for spherical tanks and water-cutting tanks is the same; it is the pressure generated by the medium inside the tank. Can a safety valve be omitted from a water-cutting tank?
Zhanjiang Fudu Liquefied Petroleum Gas Service Co., Ltd. has a total of 3 storage tanks, each with a capacity of 1,000 tons. At the time of the accident, Tank 1 and Tank 2 contained over 200 tons of liquefied petroleum gas each, while Tank 3 contained over 400 tons. Due to the severe impact of the typhoon, the inspection ladders for the 3 tanks were broken off, and the level gauge tubes at the top of each tank were also damaged, creating leakage openings of about 60 millimeters. What’s more terrifying is that the bottom of Tank 1 was also damaged by the typhoon, resulting in leakage points; this led to serious accidents involving gas leaks at the tops of Tanks 1, 2, and 3, as well as liquid leaks at the bottom of Tank 1. The liquefied gas inside the high-pressure tank at the leak site erupted at high speed, and the sound of the gas leakage could be heard even 500 meters away.
Can typhoons also blow apart ball tanks? Everyone: Although the spiral staircase for spherical tanks saves some material, it is difficult to maintain! It is estimated that along the coast of Zhanjiang, the base of the spiral stairs has completely rusted away; when a typhoon blows, it causes the gauge tubes at the top to become detached, leading to leaks!
