Is it necessary to install a burst disc in front of the safety valve of the chlorine buffer tank? The chlorine buffer tank has a capacity of 5 cubic meters, with an operating pressure of 1.0 Mpa. The set pressure of the safety valve is 1.12 Mpa. According to GB50160, for safety valves that may be corroded by the substances handled, a burst disc should be installed in front of such valves. Does this sentence mean it can be included or not? Please, experts, provide an explanation!
There’s no need to add dry chlorine; anyway, our company doesn’t add it.
Chlorine is non-corrosive; our chlorine vaporizer buffer tanks are all made of carbon steel, so there’s no problem
The owner should understand in what situations a safety valve cannot be used alone; it should not be used alone in cases where the valve disc seal may get stuck by the medium or where crystals may form within the medium. It has nothing to do with the toxicity level of the medium.
Friend, what this sentence means is that a burst disc must definitely be installed. When the standard says “should,” it means it is absolutely necessary. Moreover, the function of the burst disc is clear: to prevent the material from corroding the safety valve.
In the specifications, “should” means it is necessary. Several words in the specification require attention: “shall”, “should”, etc
What this sentence means is that it needs to be added
