1, different uses, production standards are different: medical gas copper tube, also known as medical gas or vacuum seamless copper tube, used to transport oxygen, nitrogen, carbon dioxide and other medical gases, production standards for YS/T 650; air conditioning copper tube for air conditioning and refrigeration equipment, production standards for GB/T 17791. project supervision acceptance, if the pipe production standards are inconsistent, it will lead to failure to successfully pass the acceptance.
2, medical copper pipe wall cleanliness requirements are higher: grease substances encountered in pure oxygen will occur gasification reaction, the release of a large amount of heat, easy to cause combustion or even explosion, so the medical copper pipe on the inner surface of the grease residue requirements than the air-conditioning copper pipe is more stringent, it must be degreased; at the same time, the medical copper pipe for the inner wall of the more stringent requirements for the amount of carbon residue, while the air-conditioning copper pipe is not required. Therefore, the use of air conditioning pipe instead of medical copper pipe will bring serious safety hazards.
3, different wall thickness requirements: in the case of the same or similar outer diameter, the wall thickness of medical copper pipe than air-conditioning copper pipe is thicker, longer service life.
4, printing requirements are different: medical copper tube body printing must reflect the "medical" or on behalf of the medical capital letters "YY"; air-conditioning copper tube printing format is not required.
