Do containers with coils belong to the jacketed container category?
Thread Content
As stated in the title, I would like to ask whether a storage tank with coils belongs to the category of jacketed multi-chamber containers?
It shouldn’t belong there; the coil is just a component of the storage tank
A coil is just a coil; it doesn’t belong to the jacket
Since the operating pressure inside the coil is greater than 0.1 MPa, while the storage tank is at atmospheric pressure, it does not fall under the category of multi-chamber pressure vessels. Is monitoring and inspection required for this equipment?
Reply 4# mahmah is not subject to inspection. Containers with coils do not belong to the jacketed container category, and generally the diameter of the coils is less than 150 mm; even if their volume is greater than 0.025 m3, I believe they should not be classified as such. I hope to hear the valuable opinions of all my friends

Reply to 5# JingjingCJ: The new regulations no longer specify any requirements regarding inner diameter; as long as the product of working pressure and volume is greater than 2.5 MPa·L, it falls within the scope of supervision and inspection. Check the answers to the questions related to the new regulations
What you said isn’t very clear. According to the ‘Regulations on Fixed Equipment’, coiled tubes should be regarded as separate pressure equipment. However, per clause 1.4, coiled tubes are generally classified as Category I; they do not require supervision, inspection, or notification upon installation.
Reply to 7# 198498: Regarding questions 1-31 in the answers to the questions in the \"Regulations on Safety Technical Inspection of Fixed Pressure Vessels,\" coiled tubes are regulated as pressure vessels, while storage tanks are not considered pressure vessels; in other words, only coiled tubes are subject to inspection.
According to the new regulations, no requirements are anymore imposed on the inner diameter of the equipment; therefore, whether the coil falls into a certain category depends on the operating pressure and temperature. Once it is classified into a certain category, further classification can be determined
It applies to situations where the operating pressure is 0.1 MPa or higher, the product of the operating pressure and volume is greater than 2.5 L, the medium contained is a gas or liquefied gas, and the maximum operating temperature of the medium is equal to or higher than its standard boiling point.
According to the new regulatory requirements, if the operating pressure is 0.1 MPa or higher, the product of the operating pressure and volume is greater than 2.5 MPa·L, the medium contained is a gas or liquefied gas, or the maximum operating temperature of the liquid is equal to or higher than its standard boiling point, then it is classified as Category I. In such cases, a manufacturing license is required, but no inspection, notification upon installation, etc. are necessary.
