AS 1074 (NZS 1074)ni umunya Australiya (Nouvelle-Zélande) umuyoboro rusange wibyuma hamwe nibikoresho.
Irakoreshwa kumiyoboro yicyuma hamwe nibikoresho byerekanwe muri AS 1722.1, hamwe nicyuma kirangije ibyuma kuva DN 8 kugeza DN 150.
Uburebure butatu bwurukuta rwumuyoboro wibyuma nabwo burasobanuwe, urumuri, urwego, nuburemere.
AS 1074 tubes irashobora gukorwa na kimwenta nkomyicyangwa gusudira inzira, hamwe nuburyo bwo gusudira muri rusangeERW.
Ubwoko butatu bwumuyoboro urimo: byoroshye, byegeranye, na soketi.

CE ni amagambo ahinnye ya karubone ahwanye, agomba kuboneka kubara.
CE = C + Mn / 6
Imbaraga nke z'umusaruro: 195 MPa;
Imbaraga ntarengwa: 320 - 460 MPa;
Kurambura: ntibiri munsi ya 20%.
Buri muyoboro wibyuma ugomba kugeragezwa uhitamo bumwe muburyo bwo gupima ibyuma.
Ikizamini cya Hydrostatike
Umuyoboro wibyuma ugumana umuvuduko wamazi wa MPa 5 mugihe kirekire gihagije nta kumeneka.
Ikizamini kidasenya
Ikizamini cya Eddy kiriho gihuye na AS 1074 Umugereka B.
Kwipimisha Ultrasonic ukurikije AS 1074 Umugereka C.
Urwego rwubunini bwurukuta: urumuri, urwego, nuburemere.
Urwego rwubunini bwurukuta rwicyuma rutandukana kandi niko bihanganira kwihanganira diameter.Hasi nimbonerahamwe yuburemere bwibi byiciro bitatu byumuyoboro wibyuma hamwe no kwihanganira OD.

Niba umuyoboro w'icyuma AS 1074 ushyizwemo imbaraga, ugomba guhuza na AS 1650.
Ubuso bwumuyoboro wa galvanise bugomba guhoraho, buringaniye kandi buringaniye bushoboka, kandi nta nenge yabangamira ikoreshwa.
Imiyoboro ifite imigozi igomba gushyirwaho mbere yo gutondeka.
Ibijumba bigomba gutandukanywa nibara kumpera imwe kuburyo bukurikira:

Turi abanyabugeni bo mu rwego rwo hejuru basudira ibyuma bya karuboni kandi bitanga ibicuruzwa biva mu Bushinwa, kandi tunabika ibyuma bidafite ibyuma, biguha ibisubizo byinshi byicyuma!
