Is the internal coil liquid chlorine vaporizer a pressure vessel or a non-pressure vessel?
Thread Content
I would like to ask the experts: is an internal coil liquid chlorine vaporizer a pressure vessel or a vessel of a similar type? Our company previously classified the units as non-pressure vessels, as they did not fall under the category of pressure vessels; but now, when working on it again, the equipment manufacturer claims that they are pressure vessels.
The internal coil liquid chlorine vaporizer is generally considered a pressure vessel, as its primary function is to heat liquid chlorine under sealed conditions to cause it to vaporize, and it is usually subjected to certain pressure under normal operating conditions. If your company previously classified it as an outer container, it was probably due to differences in specific usage conditions or design standards. Device manufacturers now refer to it as a pressure vessel, probably because this is determined in accordance with relevant pressure vessel standards and regulations, as well as the design parameters and operating conditions of that vaporizer. For specific details, it is necessary to consult a professional pressure vessel inspection agency or determine them in accordance with the relevant pressure vessel standards. .
Previously, the inspections weren’t strict; it was fine to just do it casually for you. But what kind of society do we live in now? How can one act carelessly? The vaporizer for liquid chlorine releases highly toxic gases that can be fatal; it’s definitely a pressure vessel. If you don’t believe it, you can check the regulations regarding pressure vessels
Thank you. Since it’s a pressure vessel, aren’t rupture discs and safety valves required? Put it where it belongs, on the outlet pipe? Should a interlocking device be included?
This liquid chlorine is a highly hazardous substance; the safety valve must be able to discharge reliably, and a full-open type safety valve should be used. Furthermore, a duct should be installed at the discharge outlet of the relief device to direct the relieved medium to a safe location for proper treatment; it must not be discharged directly into the atmosphere.
Extra-class containers and classified containers are two categories (used to determine whether they are subject to solid-container regulations); pressure vessels and atmospheric-pressure vessels are also two categories (used to determine whether there is pressure present, while the standard to be used for design is another matter)
According to the fixed-volume regulations, it must meet point 2; if it does not, it should not be classified as such.
Manufactured in accordance with pressure vessel standards, but no supervision or inspection is required
Are there any copper tube liquid chlorine vaporizers with contacts?
Coiled liquid chlorine, with hot water on the outside – not considered a pressure vessel
