Muaj pes tsawg millimeters yog txoj kab uas hla ntawm ib nti yeeb nkab?
Lub 1 nti lub tsho sib raug mus rau DN25, thiab tus qauv sab nraud yog 33.4mm. Tab sis 32 hli kuj tseem nyob hauv feem ntau daim ntawv thov.
Lub suab npe ntawm nominal (tseem hu ua nominal inch thiab nominal inch) yog siv los ua kom cov yeeb nkab thiab cov yeeb nkab fittings sib koom ua ke.
