    Marka laga reebo darajooyinka Q345A iyo Q345B, birta waa in ay ka kooban tahay ugu yaraan mid ka mid ah walxaha badarka la safeeyey ee Al, Nb, V, iyo Ti. Marka loo eego baahiyaha, alaab-qeybiyuhu wuxuu ku dari karaa hal ama in ka badan oo walxo hadhuudh ah oo la safeeyey, qiimaha ugu sarreeya waa inuu buuxiyo shuruudaha miiska. Marka la isku daro, Nb + V + Ti <0.22% °Q345, Q390, Q420 iyo Q46O, Mo + Cr <0.30% in ka badan 0.30%; marka ay u baahan tahay in lagu daro, nuxurkeedu waa in uu buuxiyo shuruudaha shaxda ama waxaa go'aaminaya alaab-qeybiyaha iyo iibsadaha iyada oo la tashanayo. aan la fulin. Haddii Al, Nb, V, Ti iyo walxo kale oo alloy ah oo leh hagaajinta nitrogen lagu daro birta, nuxurka nitrogen ma xaddidna. Waxa ku jira hagaajinta nitrogen waa in lagu qeexaa shahaadada tayada.'Marka la isticmaalayo aluminiumka, wadarta aluminiumka AIt ^ 0.020% B

    Dhererka:

    Dhererka caadiga ah ee tuubooyinka birta waa 4 000 mm ~ 12 000 mm. Ka dib markii la tashaday alaab-qeybiyaha iyo iibsadaha, oo buuxi qandaraaska, waxaa la geyn karaa tuubooyinka birta oo dhererkoodu ka weyn yahay 12 000 mm ama ka gaaban I 000 mm laakiin aan ka gaabanayn 3 000 mm; dhererka gaaban Tirada tuubooyinka birta ee ka yar 4,000 mm laakiin aan ka yarayn 3,000 mm waa in aanay ka badnayn 5% tirada guud ee tuubooyinka birta ee la keenay.

    Miisaanka gaarsiinta:
    Marka tuubada birta la keeno iyadoo loo eegayo dhexroorka dibadda ee magaca iyo dhumucda derbiga magacaaban ama dhexroorka gudaha iyo dhumucda derbiga magacaaban, tuubada birta waxaa la geeyaa iyadoo loo eegayo miisaanka dhabta ah. Waxa kale oo lagu geyn karaa iyadoo loo eegayo miisaanka aragtida.
    Marka tuubada birta la keeno iyadoo loo eegayo dhexroorka sare ee magaca iyo dhumucda gidaarka ugu yar, tuubada birta waxaa la geeyaa iyadoo loo eegayo miisaanka dhabta ah; dhinacyada saadka iyo baahida ayaa ka wada xaajooda. Waxaana lagu tilmaamay heshiiska. Dhuumaha birta sidoo kale waxaa lagu geyn karaa iyadoo loo eegayo miisaanka aragtida.

    U dulqaadashada miisaanka:
    Marka loo eego shuruudaha iibsadaha, ka dib markii la tashaday alaab-qeybiyaha iyo iibsadaha, iyo qandaraaska, leexinta u dhaxaysa miisaanka dhabta ah iyo miisaanka aragtida ee tuubada birta bixinta waa inay buuxisaa shuruudaha soo socda:
    a) Dhuumaha birta ah ee keliga ah: ± 10%;
    b) Qayb kasta oo tuubooyinka birta ah oo leh cabbirka ugu yar ee 10 t: ± 7.5%.

    Shuruudaha Imtixaanka

    Tijaabada Biyo-baxa:

    Dhuumaha birta waa in si biyo ah mid mid loo tijaabiyaa. Cadaadiska ugu badan ee tijaabada waa 20 MPa. Cadaadiska tijaabada, wakhtiga xasilinta waa inuusan ka yarayn 10 s, iyo tuubada birta ah waa inaysan daadin.

    Ka dib marka isticmaaluhu ogolaado, tijaabada hydraulicka waxa lagu bedeli karaa tijaabinta hadda jirta ama tijaabada dheecaanka birlabeedka.

    Tijaabada aan burburin:

    Tuubooyinka u baahan baaris dheeraad ah waa in ultrasonically loo baaro mid mid. Ka dib markii gorgortanku u baahan yahay ogolaanshaha dhinaca oo lagu qeexay qandaraaska, imtixaano kale oo aan burburin ayaa lagu dari karaa.

    Tijaabada fidsan:

    Tuubooyinka leh dhexroorka dibadda ee ka weyn 22 mm waa in la mariyaa tijaabo simi ah. Ma jiro delamination muuqda, baro cad, ama wasakhdu waa inay dhacaan inta lagu jiro tijaabada oo dhan.

    Tijaabada Daboolida

    Marka loo eego shuruudaha iibsadaha oo lagu sheegay qandaraaska, tuubada birta ee leh dhexroorka dibadda ≤76mm iyo dhumucda derbiga ≤8mm waxaa lagu sameyn karaa tijaabin gubasho. Tijaabada waxaa lagu sameeyay heer kulka qolka iyadoo taper ah 60 °. Daboolida ka dib, heerka ololka ee dhexroorka dibadda waa inuu buuxiyaa shuruudaha miiska soo socda, iyo walxaha tijaabada ah waa inaysan muujin dildilaacyo ama dillaac.
