AS 1074 (NZS 1074)waa Australiya (New Zealand) tuubooyinka birta guud ujeedo-guud iyo qalabyada.
Waxay khusaysaa tuubooyinka birta dunta leh iyo qalabka lagu rakibay AS 1722.1, iyo tuubooyinka birta fidsan ee laga bilaabo DN 8 ilaa DN 150.
Seddex dhumucood oo gidaar ah oo tuubo bir ah ayaa sidoo kale la cayimay, khafiif, dhexdhexaad ah, iyo culus.
Tuubooyinka AS 1074 waxaa soo saari kara midkoodaan kala go 'lahaynama hababka alxanka, oo leh habka alxanka guud ahaanERW.
Saddex nooc oo tubooyinka darafyada ah ayaa ku jira: bannaan, maroojin, iyo godad.
| Heerka | P | S | CE |
| AS 1074 (NZS 1074) | 0.045% ugu badnaan | 0.045% ugu badnaan | 0.4 max |
CE waa gacan gaaban oo u dhiganta kaarboon, kaas oo u baahan in lagu helo xisaabin.
CE = C + Mn/6
Awood dhalidda ugu yar: 195 MPa;
Xoogga ugu hooseeya: 320 - 460 MPa;
Kordhinta: aan ka yarayn 20%.
Tuubo kasta oo bir ah waa in la tijaabiyaa iyadoo la dooranayo mid ka mid ah hababka tijaabada cidhiidhiga birta.
Baaritaanka Hydrostatic
Tuubbada birta waxay ilaalisaa qiimaha cadaadiska biyaha ee 5 MPa muddo dheer oo ku filan iyada oo aan la daadin.
Tijaabada Aan Burbursanayn
Imtixaanka Eddy ee hadda wuxuu waafaqsan yahay AS 1074 Lifaaqa B.
Baaritaanka Ultrasonic si waafaqsan AS 1074 Lifaaqa C.
Darajooyinka dhumucda gidaarka: khafiif, dhexdhexaad, iyo culus.
Darajooyinka dhumucda derbiga ee tuubada birta way kala duwan yihiin sidaas awgeedna waxay u dhigantaa dulqaadka dhexroorka dibadda.Hoos waxaa ku yaal jaantuska miisaanka saddexdan darajo ee tuubada birta iyo dulqaadka OD ee u dhigma.

Haddii AS 1074 tuubada birta la galvanized, waa inay noqotaa mid waafaqsan AS 1650.
Dusha sare ee tuubada galvanized waa inay ahaataa mid joogto ah, sida siman oo siman loo qaybiyay intii suurtogal ah, oo ka nadiif ah cillado faragelin kara isticmaalka.
Tuubooyinka dunta leh waa in la galvanized ka hor inta aan dunta la gelin.
Tuubooyinka waa in lagu kala soocaa midabka hal daraf sida soo socota:
| Tube | Midabka |
| Tuubo khafiif ah | bunni |
| Tuubo dhexdhexaad ah | Buluug |
| Tuubo culus | Casaan |
Waxaan nahay soo saaraha tuubooyinka birta kaarboonka ah ee tayada sare leh iyo alaab-qeybiye ka yimid Shiinaha, iyo sidoo kale kaydiyaha birta birta ah, oo ku siinaya noocyo badan oo ah xalalka tuubooyinka birta!
