Botop Steel waa soo saaraha ugu horreeya iyo kaydka tuubooyinka birta iyo tuubooyinka ee Shiinaha, waxaan kaydinnaa oo aan bixinnaa tuubooyin bir ah oo kaarboon ah oo aan kala go 'lahayn oo wareegsan oo loogu talagalay codsiyada dareeraha iyo batroolka oo cabbirkoodu yahay 10 OD ilaa 660 OD oo dhumucdiisuna tahay 1mm ilaa 100mm. 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 8000 tan oo tuubooyin xarig ah oo aan kala go' lahayn oo kayd ah bishii, guud ahaan waxaan keeni karnaa alaabta isla markiiba. Si kastaba ha ahaatee, xaaladaha gaarka ah, haddii kaydka tuubooyinka birta kaarboonka aan la heli karin waxaan keeni karnaa alaabta waqti gaaban iyada oo loo marayo ilaha warshadaha maxalliga ah ama soo dejinta.
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.)
Codsiga:Tuubooyinka Birta Kaarboon ee aan kala go 'lahayn waxaa loo isticmaalaa in lagu qaado gaaska, biyaha, iyo batroolka warshadaha saliidda iyo gaaska dabiiciga ah. Intaa waxaa dheer, dadku waxay u isticmaali jireen ujeedo qaab-dhismeed iyo ujeedo injineernimo. Waxaan sidoo kale samayn karnaa galvanizing kulul oo lagu dhex milmay oo lagu ballaarin karo isticmaalka tuubooyinkaas.
Habka Wax Soo Saarka:Tuubooyinka Birta Kaarboon ee aan Toosanayn waxaa lagu sameeyaa qabow la jiido ama kulul la duubo, sida ku cad. Tuubooyinka kulul ee la dhammeeyay uma baahna in lagu daaweeyo kuleyl. Marka tuubada kulul ee la dhammeeyay la daweeyo kuleyl, waa in lagu daweeyaa heerkul ah 1200°F ama ka sareeya. Tuubooyinka qabow ee la shubo waa in lagu daweeyaa kuleyl ka dib marka la dhaafo qabowga ugu dambeeya heerkul ah 1200°F ama ka sareeya.
