The diameter of 300mm, volume 18L No more stress than 1MPa Dress up and compress the air In addition, does the manufacturing pressure vessel need identification? Please attach links to relevant regulations, thanks!
Friend, not a pressure vessel. Pressure vessel, it is to point to holding gas or liquid, carrying a certain pressure airtight device, the range of maximum working pressure is greater than or equal to 0.1 MPa (table), and the product of the pressure and volume of greater than or equal to 2.5 MPa l. gas, liquefied gas and the highest standard of working temperature is higher than or equal to the boiling point of the mobile and stationary containers of liquid container; All nominal working pressure is greater than or equal to 0.2 MPa pressure (table), and the product of the pressure and volume greater than or equal to 1.0 MPa, L standard of gas, liquefied gas, and the boiling point is equal to or lower than 60 ℃ liquid cylinders; Oxygen tank, etc
Belongs to a pressure vessel, in TSG R0004-2009 range, just don't need the inspection, as long as meet the manufacturing and design (general, 3.1, and 4.4.1), the requirements of the relevant specific see 1.4.2 require manufacture the device needs to have qualification to production, 4.4.1 request TSG R0004-2009 applicable scope is as follows: 1.3 the applicable scope This procedure is applicable to pressure vessel at the same time satisfy the following conditions: (1) the working pressure is greater than or equal to 0.1 MPa (note 1-2); (2) the product of work pressure and volume is greater than or equal to 2.5 MPa. (3) the highest working temperature of the medium for gas, liquefied gases, and medium is above or equal to the liquid of its standard boiling point (1-4). Of superhigh pressure vessel shall be in conformity with the super high pressure vessel safety technology supervision regulation rules, nonmetallic pressure vessels shall be in conformity with the rules of the nonmetallic pressure vessels safety and technical rules, simple pressure vessels shall be in conformity with the rules of the simple pressure vessels safety and technical rules. Note 1-2: work stress is the maximum pressure that the pressure vessel can achieve under normal working conditions (table pressure). Note 1-3: volume, which is the geometric volume of the pressure vessel, which is calculated by the dimensioning of the design pattern (not considering the manufacturing tolerance) and the roundness. Normally, the volume of the inner part of the pressure vessel should be deducted permanently.
work pressure is greater than or equal to 0.1 MPa (2) the product of job pressure and volume is greater than or equal to 2.5 MPa (3) the maximum working temperature of the medium for gas, liquefied gases, and medium is above or equal to the liquid at its standard boiling point Whether or not the container first needs to satisfy the above three conditions. It's clear how much pressure you're going to have, as long as the pressure is greater than 2.5 MPa, which is the pressure vessel. The reverse is not. If you belong to let gauge 1.4.1 a special terms and conditions of the equipment, the volume is small because of you, only 18 l, no more than 25 l, whether to belong to the simple pressure vessels, if belong to this, as long as meet the design, manufacture, and let the general requirements of rules. But anyway, as long as it's a container, the manufacturing license must be applied.
