Ingano yimiyoboro isobanuwe nimibare ibiri itari murwego:
Ingano ya Nominal (NPS) ya diameter ishingiye kuri santimetero.
Umubare Umubare (SCH kugirango ugaragaze uburebure bwurukuta rwumuyoboro.
Ingano na gahunda byombi birasabwa kwerekana neza igice runaka cyumuyoboro.
Ingano ya Nominal (NPS) nuburyo bugezweho bwo muri Amerika ya ruguru yubunini busanzwe bwimiyoboro ikoreshwa kumuvuduko mwinshi kandi muke n'ubushyuhe.Ibindi biganiro kuri ibi hano.
Ingano yicyuma (IPS) yari igipimo cyambere kuruta NPS kugirango tumenye ubunini.Ingano yari igereranijwe imbere ya diametre y'umuyoboro muri santimetero.Buri muyoboro wari ufite umubyimba umwe, witwa (STD) Ibisanzwe cyangwa (STD.WT.) Uburemere busanzwe.Icyo gihe hari urukuta 3 gusa.Muri Werurwe 1927, Ishyirahamwe ry’ubuziranenge bw’Abanyamerika ryashyizeho sisitemu yagaragazaga uburebure bw’urukuta rushingiye ku ntambwe ntoya iri hagati y’ubunini kandi itangiza Nominal Pipe Size yasimbuye Ingano y’icyuma.
Ingengabihe Yubunini bwurukuta ruri hagati ya SCH 5, 5S, 10, 10S, 20, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160, STD, XS (Ikomeye cyane) NA XXS (Double extra Mukomere).
Umuyoboro na Tubing Amasezerano yinyungu
BPE - Umuyoboro wanyuma wumukara
BTC - Umukara Wirabura & Uhujwe
GPE - Iherezo ryibibaya
GTC - Urudodo rwuzuye & Coupled
TOE - Urudodo rumwe Impera
Umuyoboro utwikiriye & Kurangiza:
Galvanised - Gipfundikirwa na zinc ikingira ibyuma kugirango wirinde ko ingese.Inzira irashobora gushyuha-gushiramo imbaraga aho ibikoresho byinjijwe muri zinc yashongeshejwe cyangwa Electro-Galvanised aho urupapuro rwicyuma ruvamo umuyoboro rwashyizwemo ingufu mugihe cyo kubyara amashanyarazi.
Bidatwikiriwe - Umuyoboro udafunze
Yirabura - Yashizwemo ibara ryijimye-oxyde
Umutuku Wibanze -Red Oxide Itukura ikoreshwa nkikoti fatizo ryibyuma bya fer, itanga ibyuma nicyuma hejuru yuburinzi
