Waxaa inta badan loo isticmaalaa in lagu sameeyo bir tayo sare leh oo qaab-dhismeedka kaarboonka ah, bir qaab-dhismeed oo isku-dhafan iyo tuubooyin bir ah oo aan lahayn kulayl u adkaysta oo loogu talagalay tuubooyinka kuleyliyaha cadaadiska sare iyo kuwa ka sarreeya uumiga.
Waxaa inta badan loo isticmaalaa cadaadiska sare iyo heerkulka sare ee kuleyliyaha (tuubada kululeeyaha, tuubada dib-u-kuleyliyaha, tuubada hagaha hawada, tuubada uumiga ugu weyn ee kuleyliyaha cadaadiska sare iyo kan aadka u sarreeya). Iyada oo ay jirto shaqada gaaska qiiqa heerkulka sare iyo uumiga biyaha, tuubadu way oksaydhmi doontaa oo way mirqi doontaa. Waxaa loo baahan yahay in tuubadu birtu ay leedahay cimri dherer sare, iska caabin sare oo oksaydheynta iyo daxalka, iyo xasillooni qaab dhismeed oo wanaagsan.

Dhumucda Darbiga iyo Dhexroorka Dibadda:
Haddii aysan jirin shuruudo gaar ah, tuubooyinka waxay noqon doonaan keenis sida dhexroorka dibadda ee caadiga ah iyo dhumucda derbiga caadiga ah. Sida ku cad warqadda soo socota.

Dhererka:
Dhererka caadiga ah ee tuubooyinka birta ah waa 4 000 mm ~ 12 000 mm. Kadib marka la tashado alaab-qeybiyaha iyo iibsadaha, oo la buuxiyo qandaraaska, waxaa la keeni karaa tuubooyinka birta ah oo dhererkoodu ka badan yahay 12 000 mm ama ka gaaban yahay I 000 mm laakiin aan ka gaabanayn 3 000 mm; dherer gaaban Tirada tuubooyinka birta ah ee ka yar 4,000 mm laakiin aan ka yarayn 3,000 mm waa inaysan ka badnaan 5% tirada guud ee tuubooyinka birta ah ee la keenay
Miisaanka keenista:
Marka tuubada birta ah la keeno iyadoo loo eegayo dhexroorka dibadda ee magacaaban iyo dhumucda derbiga magacaaban ama dhexroorka gudaha ee magacaaban iyo dhumucda derbiga magacaaban, tuubada birta ah waxaa la keenaa iyadoo loo eegayo miisaanka dhabta ah. Waxa kale oo la keeni karaa iyadoo loo eegayo miisaanka aragtiyeed.
Marka tuubada birta ah la keeno iyadoo loo eegayo dhexroorka dibadda ee magacaaban iyo dhumucda derbiga ugu yar, tuubada birta ah waxaa la keenaa iyadoo loo eegayo miisaanka dhabta ah; dhinacyada sahayda iyo baahida ayaa ka wada xaajooda. Waxaana lagu tilmaamay qandaraaska. Tuubada birta ah waxaa sidoo kale la keeni karaa iyadoo loo eegayo miisaanka aragtiyeed.
Dulqaadka miisaanka:
Sida waafaqsan shuruudaha iibsadaha, ka dib marka la tashado alaab-qeybiyaha iyo iibsadaha, iyo qandaraaska, kala-duwanaanshaha miisaanka dhabta ah iyo miisaanka aragtiyeed ee tuubada birta ah ee keenista waa inay buuxisaa shuruudaha soo socda:
a) Tuubo bir ah oo keliya: ± 10%;
b) Dufcad kasta oo tuubooyin bir ah oo cabbirkoodu ugu yaraan yahay 10 t: ± 7.5%.
Tijaabada Haydarooliga ah:
Tuubada birta ah waa in mid mid loo tijaabiyaa iyadoo la adeegsanayo hawo-mareenka. Cadaadiska tijaabada ugu badan waa 20 MPa. Cadaadiska tijaabada, waqtiga xasilinta waa inuu ahaadaa mid aan ka yarayn 10 ilbiriqsi, tuubada birta ahna waa inaysan daadan.
Ka dib marka isticmaaluhu ogolaado, tijaabada haydarooliga waxaa lagu beddeli karaa tijaabada hadda jirta ee eddy ama tijaabada daadashada qulqulka magnetic-ka.
Tijaabada aan burburin:
Tuubooyinka u baahan baaritaan dheeraad ah waa in mid mid loo baaro iyadoo la isticmaalayo ultrasound. Ka dib marka gorgortanku u baahdo ogolaanshaha dhinaca oo lagu qeexay qandaraaska, waxaa lagu dari karaa baaritaanno kale oo aan burburin.
Imtixaanka Fiditaanka:
Tuubooyinka leh dhexroor dibadda ah oo ka weyn 22 mm waa in lagu sameeyaa tijaabo siman. Lama arki karo dildilaac, dhibco cad, ama wasakh inta lagu jiro tijaabada oo dhan.
Tijaabada Dab-damiska:
Sida waafaqsan shuruudaha iibsadaha iyo qandaraaska ku xusan, tuubada birta ah ee leh dhexroorka dibadda ≤76mm iyo dhumucda derbiga ≤8mm ayaa la samayn karaa tijaabada flaring. Tijaabada waxaa lagu sameeyay heerkulka qolka iyadoo leh 60 °. Ka dib flaring, heerka flaring ee dhexroorka dibadda waa inuu buuxiyaa shuruudaha jadwalka soo socda, walxaha tijaabada ahna waa inaysan muujin dildilaac ama jeexjeex.
