Questions regarding the selection standards for clean pipelines in the pharmaceutical industry
Thread Content
I work in the engineering and installation sector of the pharmaceutical industry, and I have always been confused regarding the selection of standards for cleanroom pipes and valves. Although standards such as ISO 2037, DIN, and 3A are commonly used nowadays, actual projects in China often involve pipe diameters and wall thicknesses that differ from those specified in these standards. Is there anyone who has extensive knowledge in this area? Are there any corresponding standards available for use in China?
No, when purchasing domestically, one can generally only require specifications regarding the roughness of the pipes, as well as standard requirements for cleanliness and other related aspects
