AS 1074 (NZS 1074)waa tuubo bir ah oo loogu talagalay ujeedo guud oo Australian (New Zealand) ah iyo qalab bir ah.
Waxay khuseysaa tuubooyinka birta ah ee dunta leh iyo qalabka ku habboon ee lagu qeexay AS 1722.1, iyo tuubooyinka birta ah ee fidsan ee ka bilaabma DN 8 ilaa DN 150.
Saddex dhumuc oo derbi ah oo tuubo bir ah ayaa sidoo kale la cayimay, khafiif ah, dhexdhexaad ah, iyo culus.
Tuubooyinka AS 1074 waxaa soo saari kara midkoodaan kala go 'lahaynama hababka alxanka, iyadoo habka alxanka guud ahaan uu yahayERW.
Saddex nooc oo darafyo tuubo ah ayaa ku jira: mid caadi ah, mid xoqan, iyo mid god leh.
| Heerka Caadiga ah | P | S | CE |
| AS 1074 (NZS 1074) | 0.045% ugu badnaan | 0.045% ugu badnaan | 0.4 ugu badnaan |
CE waa gaabin loogu talagalay u dhiganta kaarboonka, kaas oo loo baahan yahay in lagu helo xisaab ahaan.
CE = C + Mn/6
Xoogga wax soo saarka ugu yar: 195 MPa;
Xoogga ugu yar ee jiidista: 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 adkeynta tuubada birta ah.
Imtixaanka Hydrostatic-ka
Tuubada birta ah waxay ilaalisaa qiimaha cadaadiska biyaha ee 5 MPa muddo ku filan oo aan daadan.
Tijaabada Aan Burburinayn
Tijaabada hadda ee Eddy waxay waafaqsan tahay AS 1074 Lifaaqa B.
Tijaabada Ultrasonic-ka iyadoo la raacayo AS 1074 Lifaaqa C.
Darajooyinka dhumucda derbiga: khafiif, dhexdhexaad, iyo culus.
Dhererka dhumucda derbiga ee tuubooyinka birta ah way kala duwan yihiin, sidoo kale dulqaadka dhexroorka dibadda ee u dhigma ayaa kala duwan. Hoos waxaa ku qoran jadwalka miisaanka saddexdan darajo ee tuubooyinka birta ah iyo dulqaadka OD ee u dhigma.

Haddii tuubo bir ah oo AS 1074 ah la geliyo galvanized, waa inay waafaqsanaato AS 1650.
Dusha sare ee tuubada galvanized-ka ah waa inay noqotaa mid joogto ah, siman oo si siman u baahsan intii suurtagal ah, kana xor ah cillado faragelin kara isticmaalka.
Tuubooyinka leh dunta waa in la galgalo ka hor inta aan la saarin dunta.
Tuubooyinka waxaa lagu kala saari doonaa midab dhinac kasta sida soo socota:
| Tube | Midab |
| Tuubo khafiif ah | Bunni |
| Tuubo dhexdhexaad ah | Buluug |
| Tuubo culus | Casaan |
Waxaan nahay soo-saare iyo alaab-qeybiye tuubooyin bir ah oo tayo sare leh oo laga sameeyay Shiinaha, iyo sidoo kale shirkad kaydisa tuubooyinka birta ah oo aan kala go 'lahayn, annagoo ku siinayna xalal badan oo tuubooyinka birta ah!
