Muri rusange, diameter yumuyoboro urashobora kugabanywamo diameter yo hanze (de), diameter yimbere (d), imyenda yizina (Dn).
Hasi kugirango uyihe itandukaniro riri hagati yiyi "de, D, DN".
DN ni diameter yuzuye umuyoboro
Icyitonderwa: Ibi ntabwo ari diameter yo hanze cyangwa diameter yimbere; bigomba kuba bifitanye isano no guteza imbere imiyoboro ya pieline hamwe nibice byibwami; Mubisanzwe bikoreshwa mugusobanura umuyoboro wicyuma gakomeye, uhuye nibice byibwami kuburyo bukurikira:
Igice cya 4: 4/8 Inch: DN15;
Umuyoboro w'iminota 6: 6/8 Inch: DN20;
Umuyoboro wa santimetero 1: 1 Inch: DN25;
Santimetero ebyiri: 1 na 1/4: Dn32;
Umuyoboro wa santimetero: 1 na 1/2: DN40;
Umuyoboro wa santimetero ebyiri: santimetero 2: DN50;
Umuyoboro wa santimetero eshatu: santimetero 3: DN80 (Ahantu henshi nanone byanditseho DN75);
Umuyoboro wa santimetero enye: santimetero 4: DN100;
Amazi, umuyoboro wa gaze (Icyuma cya Gallecyangwa umuyoboro udasimba), fata ibyuma, ibyuma-plastike-pulastike hamwe nibikoresho bya phipe hamwe nibindi bikoresho, bigomba gushyirwaho na diaxter
De cyane cyane bivuga diameter yo hanze yumuyoboro
Gukoresha muri rusange de labeling, bigomba kwandikwa muburyo bwa diameter ya diameter X;
Cyane cyane mu gusobanura:umuyoboro utagira ingano, PVC hamwe nizindi miyoboro ya pulasitike, nizindi miyoboro isaba urukuta rusobanutse.
Fata ibyuma bisukuye isesutse nkurugero, hamwe na DN, de uburyo bubiri bwa labels ni bukurikira:
Dn20 de25 × 2.5m
Dn25 de32 × 3mm
Dn32 de40 × 4mm
Dn40 de50 × 4mm
......
D mubisanzwe bivuga diameter yimbere yumuyoboro, D yerekana diameter yimbere yumuyoboro wa beto, na φ yerekana diameter y'uruziga rusanzwe
Φ irashobora kandi kwerekana diameter yo hanze yumuyoboro, ariko rero igomba kugwizwa nubwinshi bwurukuta.
Kurugero, φ25 × 3 bisobanura umuyoboro ufite diameter yo hanze ya 25mm nubwinshi bwa 3mm.
Umuyoboro wa Stead utagira umuyoboro cyangwa umuyoboro wa ferros, ugomba gushyirwaho ikimenyetso "diameter yo hanze × urufunguzo".
Kurugero: φ107 × 4, aho φ ishobora gusibwa.
Ubushinwa, Iso na Ubuyapani igice cy'icyuma cy'icyuma ukoresheje ibipimo by'urukuta kugira ngo werekane urukuta rw'urukuta rw'imigezi y'ibyuma. Kuri ubu bwoko bwimiyoboro yicyuma, uburyo bwo kwerekana umuyoboro hanze ya diamester × URUPFU. Kurugero: φ60.5 × 3.8
De, DN, D, Ф Ф Фотzo
De-- ppp, pe pipa, polypropylene umuyoboro od
Dn - Polyethylene (pvc) umuyoboro, cast ibyuma, ibyuma-plastike igihuru
d - umuyoboro wa beto nominal diameter
Ф - Ibyuma bitagira ingano nominal diameter
