Tuubbo Bir ah oo Botop ahwaa soo saaraha ugu horreeya iyo kaydka tuubooyinka birta iyo tuubooyinka ee Shiinaha codsiyada cabbirka u dhexeeya 355.6 OD ilaa 1500 OD oo dhumucdiisuna tahay 8mm ilaa 80mm, waxaan kaydinnaa oo bixinnaa tuubooyin bir ah oo kaarboon ah oo wareegsan oo aan kala go 'lahayn oo loogu talagalay dareeraha iyo batroolka. Waxaan si adag u soo saarnaa tuubooyinka birta kaarboonka LSAW iyadoo loo eegayo heerka caalamiga ah sida ASTM, API & DIN. Waxaan leenahay in ka badan 15000 tan oo tuubooyin LSAW ah oo la soo saaro bishii, guud ahaan waxaa naloo soo saari karaa alaabta sida ugu dhakhsaha badan.
Dhammaan tuubooyinka birta ah iyo alaabada tuubooyinka waxaa la siiyaa shahaadooyin tijaabo oo gaar ah oo 3.1 ah, sida waafaqsan EN 10204. Shahaadada sida waafaqsan 3.2 waa la isku raaci karaa wakhtiga la dalbanayo. Kormeerka dhinac saddexaad waa la aqbalayaa (BV, SGS, iwm.)

2. Ka-baxsan-Meel-wareejin - Farqiga u dhexeeya dhexroorka dibadda ee waaweyn iyo kuwa yaryar.
3. Isku-dubarid - Adeegsiga 10 ft (3m) oo toosan oo la dhigay si labada darafba ay ula xiriiraan tuubada, 1/8 inji (3mm).
4. Dhumucda - Dhumucda derbiga ugu yar meel kasta oo tuubada ah waa inaysan ka badnaan 0.01 inji (0.3mm) marka loo eego dhumucda magacaaban ee la cayimay.
5. Dhererka leh darafyo aan la madhin waa inuu ahaadaa -0+1/2 inji (-0+13mm) ee la cayimay. Dhererka leh darafyo madhin waa inuu ahaadaa sida ay isku raaceen soo saaraha iyo iibsadaha.
