Which manufacturing code is more appropriate to apply for non-pressure vessels in accordance with the regulations?

Thread Content

According to the General Administration of Quality Supervision, Inspection and Quarantine’s Order No. 114 of 2014 on the revision of the Catalogue of Special Equipment. Pressure vessels refer to enclosed devices used for holding gases or liquids and capable of withstanding certain pressures. They are defined as fixed or mobile containers whose maximum operating pressure is 0.1 MPa (gauge pressure) or higher for gases and liquefied gases, and whose maximum operating temperature is equal to or higher than their standard boiling point; such containers also have a volume of 30 L or more and an inner diameter of 150 mm or more (for non-circular cross-sections, this refers to the largest geometric dimension of the cross-sectional boundary) ； Gas cylinders, liquefied gas cylinders, and cylinders for liquids with a standard boiling point of 60°C or lower, whose nominal working pressure at full charge is greater than or equal to 0.2 MPa (gauge pressure), and whose product of pressure and volume is greater than or equal to 1.0 MPa•L ； Oxygen chamber. The existing equipment has a volume of 15 L and an inner diameter of 125 mm; it is a fixed container that, according to relevant standards, does not fall under the category of pressure vessels. At present, there is no desire to use GB150 as the manufacturing standard, as products manufactured according to this standard are bulky and uneconomical. Is there a more suitable design standard?
