Gusobanura neza ubunini bwicyuma gikeneye gushyiramo ibintu byinshi byingenzi:
Hanze ya Diameter (OD)
Diameter yo hanze yumuyoboro wibyuma, mubisanzwe bigaragazwa nkumurambararo wa nomero (DN) cyangwa ingano yumuyoboro (NPS).
Ingano ya Nominal (NPS) na Nominal Diameter (DN)
NPS nubunini bwizina bushingiye kuri santimetero, mugihe DN ni diameter nominal muri milimetero.Isano yo guhinduka iroroshye: agaciro ka DN kangana nagaciro ka NPS kagwijwe na 25.4 (mm / inch) kugirango uzenguruke ibisubizo.
Mu myitozo, inzandiko zandikirwa hagati ya NPS na DN zishingiye cyane kumeza yuburinganire busanzwe bwashyizweho.
Uburebure bw'urukuta (WT)
Ubunini bwurukuta rwumuyoboro.Ku muyoboro usanzwe, ubunini bwurukuta akenshi bujyana na Gahunda yumuyoboro, urugero Gahunda ya 40 cyangwa Gahunda ya 80, aho indangagaciro nini zerekana inkuta ndende.
Uburebure
Uburebure bw'umuyoboro w'icyuma, ushobora gukosorwa cyangwa gutondekwa, bitewe n'umusaruro n'ibisabwa.Uburebure busanzwe ni metero 6 na metero 12.
Ibikoresho
Ibipimo ngenderwaho hamwe n amanota yumuyoboro wibyuma, nka ASTM A106 Icyiciro B, API 5L Icyiciro B, nibindi. Ibipimo ngenderwaho byerekana imiterere yimiti nibintu bifatika byumuyoboro.
Ibipimo
Ibipimo ngenderwaho byumuyoboro wa karubone nicyuma cyane cyane ukurikiza ASME B36.10M (ibyuma bya karubone na alloy) na B36.19M (umuyoboro wibyuma).
Ingano yubunini bwimbonerahamwe hamwe nuburemere bwibipimo (WGT)
tanga uburyo busanzwe bwo gusobanura uburebure bwurukuta rwumuyoboro munsi yimirimo itandukanye, kimwe no gutondekanya amanota yuburemere nka STD, XS, XXS, nibindi.
Uburebure bw'urukuta rw'umuyoboro bugira ingaruka ku buryo bw'imbere n'uburemere bw'umuyoboro.Ubunini bwurukuta ni ngombwa kuko bugena ingano yumuvuduko wimbere umuyoboro ushobora kwihanganira.
Umubare w'urutonde
Uburyo bwo kwerekana uburebure bwurukuta rwumuyoboro, mubisanzwe nka Gahunda ya 40 na 80, bivuga uburebure bwurukuta rusanzwe kandi bushimangiwe bwumuyoboro wa diameter yatanzwe hanze.
Ikigereranyo cyagereranijwe cyumubare ni gahunda ikurikira:
Kubera ubushobozi bwabo bwo guhangana ningutu zisanzwe, Gahunda ya 40 na Gahunda 80 ibyuma bikenerwa cyane mubikorwa bitandukanye.Kubera ko iyi miyoboro yagenewe guhangana n’umuvuduko mwinshi, akenshi irasabwa ari myinshi kugirango ihuze ibikenewe ninganda zitandukanye.

Kubwibyo, urugero rwuzuye rwerekana ubunini bwicyuma gishobora kuba "NPS 6 cm, Gahunda 40, ASTM A106 Icyiciro B, Uburebure bwa metero 6".Ibi byerekana umuyoboro wicyuma ufite diameter nominal ya santimetero 6, Gahunda ya 40, yakozwe kuri ASTM A106 Icyiciro cya B, n'uburebure bwa metero 6.
