Does PVC medical oxygen tank belong to the pressure vessel
Does not belong to, the hospital use oxygen tank low pressure, said oxygen cabin just inside the hull high purity oxygen than ordinary air, oxygen tank need oxygen therapy is directly into the human body, pressure is less than 0.1 MPa, lung capacity good desperately blowing to the pressure list of adults, not more than 0.3 MPa, can blow hot water bag, 0.1 MPa was enough to blowing up balloons, enter human body can't breathe, say simple point is the hull atmospheric oxygen of high purity.
It's a pressure vessel. Special equipment safety inspection ordinance Article 99 the meanings of the following terms in these regulations are: (2) of pressure vessel, it is to point to holding gas or liquid, carrying a certain pressure airtight device, its range for 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.
PVC medical oxygen tank is a pressure vessel. PVC medical oxygen tank satisfies pressure vessel condition. Conditions for pressure vessels: (1) the container is sealed by the cylinder, and the head of the convex search (not including the spherical head), Or consists of two convex heads; (2) the material of the main compression elements, such as barrel, head, and takeover, is carbon steel, Austenitic stainless steel; (3) design pressure is less than or equal to 1.6 MPa; (4) the volume is less than or equal to 1000L; (5) the product of work pressure and volume is greater than or equal to 2.5 MPa Less than or equal to 1000MPa. (6) the vapor that evaporates into the air, the nitrogen and the medicinal distilled water; (7) design temperature is greater than or equal to - 20 ℃, the highest working temperature is less than or Is equal to 150 ℃; (eight) indirect flame welding containers. Medical plastics industry with its high value-added, high growth and has broad market potential and high-profile, through the adoption of new type of plastic material, can make medical equipment safer, more environmentally friendly. Over the past 15 years, the international medical plastic products market has grown at an average annual rate of 1518%, ranking among the annual growth rates of all kinds of medical device products.
