OEM China ASTM A106/ API 5L / ASTM A53 darajada b birta birta ah ee dhuumaha saliidda iyo gaaska
Dulmar
Had iyo jeer waxaan shaqada ku helnaa annaga oo ah koox xirfadle ah si aan u hubinno inaan si fudud kuugu siin karno tayada ugu sareysa iyo heerka ugu waxtarka badan. Wixii ASTM A106/ API 5L / ASTM A53 fasalka B ee tuubada birta ah ee saliidda iyo dhuumaha gaaska, waxaan leenahay khibrad 3 toban sano ka badan si aan u siino xaalado codsi oo kala duwan. Waxaan u qaadan doonaa qancinta macmiilka sida ugu badan, waxaan u isticmaali doonaa kheyraadkayaga si aan u bixino waxa dhabta ah ee macmiilkayagu u baahan yahay oo aanu ugu badnaan karno wax ku oolnimada macmiilkayaga.
Waxaan si diiran u soo dhawaynaynaa macaamiisha gudaha iyo dibaddaba inay soo booqdaan shirkadeena oo ay la yeeshaan wadahadal ganacsi. Shirkadeena had iyo jeer waxay ku adkaysataa mabda'a "tayo wanaagsan, qiimo macquul ah, adeegga heerka koowaad". Waxaan diyaar u ahayn inaan idinla dhisno iskaashi saaxiibtinimo oo fog, saaxiibtinimo iyo faa'iido leh.

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 yar-yar, cabbirka hadhuudhka, iyo lakabka decarburization ee tuubada birta ee dhammaatay.
