Questions regarding pressure vessels
Thread Content
Our unit has installed a Taibei-type condensate recycler; it only features a differential pressure indicator and no glass panel display. Some people say that since it is a pressure vessel, both types of indicators are necessary. I’m not sure if there are any standards regarding this; if so, what is the standard number?
“Regulations on Safety Inspection of Pressure Vessels” 1. The maximum operating pressure (Pw) *** is greater than or equal to 0.1 MPa (excluding hydrostatic pressure; the same applies hereafter)； ＊＊ 1. For pressure vessels subjected to internal pressure, the maximum operating pressure refers to the highest pressure that may occur at the top of the vessel during normal use ； 2. For pressure vessels subjected to external pressure, the maximum operating pressure refers to the highest pressure that may occur at the top of the jacket during normal use of the pressure vessel. 2. The inner diameter (for non-circular cross-sections, this refers to the largest dimension of the cross-section) is greater than or equal to 0.15 m, and the volume (V)****** is greater than or equal to 30.025 m³ ； ＊＊＊Volume refers to the geometric volume of a pressure vessel, that is, the volume calculated from the dimensions specified in the design drawings (without considering manufacturing tolerances) and rounded off, without deducting the volume of internal fittings. 3. The medium is a gas, a liquefied gas, or a liquid with a maximum operating temperature equal to or higher than its standard boiling point.
I’ve also seen this procedure; it seems to have nothing to do with the level gauge
Not all pressure vessels are equipped with a level gauge.
Pressure vessels are unrelated to the presence or absence of a level gauge; Beining’s products, which are closed-type steam and condensate recovery units, fall under the category of pressure vessels.
What was said upstairs is absolutely correct. I have read the rules numerous times and haven’t found any provisions related to glass panels. In fact, the original poster could also read the rules thoroughly to avoid being misled by others.
Have you seen North Ning’s products? We are using them. How can one know the amount of water without a level gauge? How can the start and stop times as well as the intervals for the pump be set?
It’s debatable whether it constitutes a pressure vessel, and moreover, level monitoring doesn’t necessarily require direct contact measurement
The setting of the level gauge has no direct relation to whether it is a pressure vessel; it is determined based on process requirements.
