Mu miyoboro ya pipine fitingi ya valve pompe nibindi bishushanyo cyangwa amasoko dukunze guhura na DN, santimetero “, Φ nibindi bice, hariho inshuti nyinshi (cyane cyane shyashya inkweto zinganda) kubwibyo bitesha umutwe, ntibishobora gutandukanya icyitegererezo, uyumunsi twe azavuga muri make incamake yibice bitatu bigize isesengura ryihariye ryakarere.
1.DN
“DN” inshuti nyinshi zibeshya zibwira ko ari diameter y'imbere, mubyukuri DN na diameter y'imbere ya bamwe bafunze, ariko hafi gusa, igisobanuro cyacyo nyacyo ni umuyoboro, umuyoboro, fitingi nominal diameter, diameter nominal (Nominal Diameter), uzwi kandi nka impuzandengo yo hanze ya diameter (Hagati ya Diameter), mubyukuri, ni impuzandengo yo hanze ya diameter.
Mu gihugu DN agaciro gakondo ni rusange cyane, ariko mumuyoboro, imiyoboro ya valve na valve bishobora kugereranya igice gusa, kuki igice cyacyo?Kuberako muri sisitemu yo mu gihugu imbere, hashobora kubaho ubwoko bubiri bwa diameter yo hanze mumurongo umwe wanditseho DN (Φ ni diameter yo hanze yumuyoboro cyangwa umuyoboro, tuzabisobanura nyuma), nka DN100, hariho I seriyeri na II (na none) ingirakamaro kuranga Urukurikirane na B B), I Urukurikirane na Urukurikirane rwa DN100 ni Φ114.3, mugihe II serie na B ya DN100 ni Φ108.Niba udasobanuye diameter yo hanze ya pipe Φ nyuma ya DN mugihe werekana gahunda nibisobanuro birambuye, ugomba gusobanura neza niba ari I serie (A serie) cyangwa II serie (B seri) mugihe ushizeho ikimenyetso na DN, kugirango birasobanutse mugikorwa cyo kugura no kubaza, kandi urashobora kumenya ubwoko bwumuyoboro cyangwa uhuza diameter hanze ushaka nta itumanaho kandi byemejwe.
2. Inch
Inch ”ni igice cyubwami, gikoreshwa cyane muri Amerika no mu Burayi, nacyo ni igice, byumvikane ko gifite umuyoboro wa Pipe na Tube, uyu munsi tugomba gusobanura icyiciro cya Pipe cyibikoresho na fitingi, nyuma tuzabimenyekanisha, Umuyoboro wa Pipe na Tube imiyoboro itandukanye.
Mu miyoboro ya Pipe, santimetero ntabwo imeze nka DN kugirango itandukane diameter yo hanze yubwoko bubiri bwimiyoboro, ni igice gisobanutse, nka 4 ″ yerekanwe neza ni diameter yo hanze 114.3, naho 10 ″ ni Φ273, mugihe cyose umuyoboro cyangwa ibikoresho byasobanuwe na santimetero birashobora kumenyekana neza hatabanje kwemezwa ubunini bwa diameter yo hanze.
3. Diameter Φ
Ikimenyetso cya diameter ni “Φ”, kikaba kiri mu nyuguti z'ikigereki, cyiswe “fai”, kandi gifite umubano wa hafi cyane na bibiri byabanjirije iki, kuko gishobora gusimbuza ibice bibiri byavuzwe haruguru, n'umuyoboro cyangwa umuyoboro ukoresheje Φ nuburyo busobanutse neza, kandi nuburyo butaziguye nta guhinduka, nka 1919, Φ508, 201020, nibindi. Ubu buryo bwo kumenyekanisha nabwo ni bunini cyane.
