Kanjikanji kuli beenzuma batamvwisyi kujatana aakati ka "DN", "Φ" lubo """. Mazubaano, ndilakupandulula mubufwiifwi kujatana aakati kabo botatwe, ndisyoma kuti ndiyookugwasya!
inchi ninzi”
Inchi (") nchintu chibelesyegwa kapati mubweendelezi bwaku Amelika, mbuli mapaipi aabutale,mavalvu, ma flanges, ma elbows, ma pomps, tees, azimwi, mbuli kuti 10′′.
Inch (inch, yakafwiinsigwa kuti in.) chaamba chaala muchiDutch, mpawo inchi mbulamfwu bwa chaala. Masimpe, bulamfwu bwechikumbo abwalo buliindene. Mumwaanda wamyaka wakkumi aane, Mwami Edward Wabili wakaambilizya "Mulawu Uuzumizyidwe". Mulawu ngwakuti bulamfu bwamaila otatwe mapati aasalwa kuzwa akati kamatwi aabbaale mpawo abikkwa mumulongo mbu inchi yomwe.
Kanjikanji 1′′=2.54cm=25.4mm
Ino DN ninzi
DN ninzila iibelesyegwa kapati muChina akuYulopu, mpawo ninzila yakulemba mapaipi,mavalvu, maflange, zibelesyo, amapompi, mbuliDN250.
DN chaamba bupati bwamupayipi (alimwi buzyibidwe kuti bupati bwamupayipi), amubone: oobu tabuli bupati bwaanze naa bupati bwamukati, pele mweelwe waakati-kati wabwamba bwaanze abwaamba bwamukati, bwiitwa kuti mweelwe waakati-kati wabwamba bwamukati.
NiinziΦ
Φ nchintu chidumide, chaamba bupati bwaanze bwamapayipi, naakuti zikobela, nsimbi zizungulukide azintu zimwi.
Ino ncinzi ciswaangene aakati kabo?
Chakusanguna, bupanduluzi bulembedwe a “”" a "DN" bulikozyenye. Bupanduluzi bwaamba bupati bwazina, kutondezya bupati bwachintu eechi, mpawoΦ nkusanganya zyoonse zyobile.
mbuli mukozyanisyo
Mbuli chitondeezyo, ikuti payipi yabutale kaili DN600, ikuti payipi njiyonya yabutale yalembedwe mumainchi, ilaba 24′′. Mpu kuli kujatana aakati kazeezi zyobile?
Bwiinguzi mbwakuti inzya! Inchi yoonse ninamba iizwide mpawo yavwuzyigwa a 25 yeendelana a DN, mbuli 1′′*25=DN25, 2′′*25=50, 4′′*25=DN100, azimwi. Masimpe, kuli zimwi zilimbuli 3′′*25=75 Kuzinguluka DN80, mpawo kuli zimwi zili muma semicolon naa ma decimal mbuli 1/2″, 3/4″, 1-1/4″, 1-1/2″, 2-1/2″, 3-1/ 2″ azimwi, eezyi tazikonzyi kubalwa boobo, pesi kubala kulikozyenye, mubwini mweelwe waambwa:
1/2″=DN15
3/4′′=DN20
1-1/4′′=DN32
1-1/2″=DN40
2′′=DN50
2-1/2″=DN65
3′′=DN80
