Tayo Wanaagsan Shiinaha oo aan Xumaan lahayn Tuubbada Birta Kaarboonka ee Birta
Si aan kuu awoodno inaan ku siino faa'iido oo aan u weyneyno ganacsigeena, waxaan sidoo kale ku leenahay kormeerayaal kooxda QC ah oo aan kuu xaqiijinno adeeggayaga iyo alaabtayada ugu weyn ee Tayada WanaagsanShiinaha Tube-ka Carbon Steel Tube Aan Xumaan lahaynDhuumaha birta, Ujeeddooyinkayada ugu muhiimsan waa in aan ku gaarsiinno macaamiisheena adduunka oo dhan tayo wanaagsan, qiimo tartan leh, gaarsiinta farxadda leh iyo bixiyeyaasha heersare ah.
Si aan u awoodno in aan ku siino faa'iido oo aan u weyneyno ganacsigeena, waxaan sidoo kale ku leenahay kormeerayaal kooxda QC oo aan kuu xaqiijinno adeeggayaga iyo alaabtayada ugu weynShiinaha Tube-ka Carbon Steel Tube Aan Xumaan lahayn, tuubo bir ah oo aan lahayn, Alaabtayadu waxay ku guuleysteen sumcad aad u wanaagsan mid kasta oo ka mid ah quruumaha la xiriira. Sababtoo ah aasaaska shirkadeena. Waxaan ku adkaysanay hal-abuurnimada habraacayaga wax-soo-saarka oo ay weheliso hab-maamuleedka casriga ah ee ugu dambeeyay, anagoo soo jiidannay tiro badan oo karti ah gudaha warshadahan. Waxaan u aragnaa xalka tayada wanaagsan inuu yahay dabeecadeena nuxurka ugu muhiimsan.

Shuruudaha Imtixaanka
Marka lagu daro hubinta isku dhafka kiimikada iyo sifooyinka farsamada, tijaabooyinka hydrostatic ayaa la sameeyaa mid mid, waxaana la sameeyaa tijaabooyinka fidinta iyo fidinta. . Intaa waxaa dheer, waxaa jira shuruudo gaar ah oo loogu talagalay qaab-dhismeedka yaryar, cabbirka hadhuudhka, iyo lakabka decarburization ee tuubada birta ee dhammaatay.
