Dn10的意思

"DN10" is a designation used in pipe and fitting standards, particularly in European standards such as ISO 228 or DIN 2458. It refers to the nominal diameter of a pipe or fitting. The "DN" stands for "nominal diameter" and the number (10 in this case) indicates the size of the pipe in millimeters.

Here's a breakdown of what "DN10" means:

• "DN" (or "Diameter Nominal") is a designation used to indicate the nominal bore of a pipe. It's a general size indicator and does not correspond to the actual outside diameter (O.D.) of the pipe.

• The number "10" indicates that the nominal bore of the pipe is 10 millimeters.

It's important to note that the actual outside diameter of a pipe with a DN10 designation may vary depending on the pipe's material, schedule (thickness), and standard. For example, a DN10 steel pipe in schedule 40 might have an outside diameter of approximately 10.3 mm, while a DN10 plastic pipe might have a slightly different O.D.

When working with pipes and fittings, it's crucial to refer to the specific standards and dimensions relevant to the material and application in question.
