Amatanthauza m'mimba mwake akunja, ndipo DN amatanthauza m'mimba mwake DN: m'mimba mwake mwadzina: m'mimba mwake

Tsopano machubu--.monga ali mainchesi, mamilimita ndi kungoyerekeza, zosavuta kukumbukira chiwerengero.

Mwachitsanzo, chitoliro cha DN50 chiyenera kukhala 2 mainchesi, 1 inchi = 25.4mm, 2 mainchesi akhale 50mm,

Panthawi imeneyi, makulidwe a khoma la chitoliro, chitoliro chozungulira chili pamwamba pa 5mm, kutenga 5mm monga chitsanzo,

The awiri akunja chubu DN50 ayenera kukhala pafupifupi 60mm.

Q345 opanda chitsulo chitoliro kwenikweni ndi mtundu wa zitsulo chitoliro chuma.Q imayimira zokolola za zinthu izi,
