Soo saaraha Shiinaha ee Shiinaha Qaybta Alloy Steel Pipe Tube ASTM A335 Kuleyl u adkaysata Gaaska Hawada Kuleyliyaha Shidaalka
Dulmar
Waxaan ku tiirsannahay xoog farsamo oo adag waxaanan si joogto ah u abuurnaa tignoolajiyada casriga ah si aan u daboolno baahida Soo-saaraha Shiinaha ee ASTM A335 Heat-Dib-u-hortaag aan Xumaan lahayn ee Alloy Steel Pipe , Waxaan siinaa mudnaanta tayada sare iyo raaxada macaamiisha iyo tan waxaan raacnaa tillaabooyinka xakamaynta tayada wanaagsan. Waxaan hadda leennahay tas-hiilaad tijaabo ah oo guriga dhexdiisa ah halkaas oo xalalkeena lagu tijaabiyo dhinac kasta oo heerar kala duwan ah. Lahaanshaha teknoolajiyada ugu dambeeyay, waxaan u fududeeya macaamiisheena la habaysan wax soo saarka facility.Company Magaca, had iyo jeer waa la xiriira tayada sida aasaaska shirkadda, raadinta horumarinta via heerka sare ee kalsoonida , u hoggaansamaan heerka maamulka tayada ISO si adag, abuurista sare-sare shirkad by by ruuxa horumarka-astaan daacadnimo iyo yididiilo.
Waxaa jira soo bandhigid T91/P91 aluminium birta kuleyliyaha ah
1. Hordhaca Heerka Birta
T91 / P91 waa bir u adkaysata kulaylka ferritic, by tiifka geedkii shaybaarka qaranka ee 1970-yadii bilaabay cilmi-baarista iyo horumarinta, iyo 1983 ee ASME, dalkeena 1995 ilaa birta galay heerka GB 5310, sumadda sida 10 cr9mo1vnbT91 / P91 steel ahaa 9 cr1mo (T9), oo ku salaysan birta, daahirsanaanta, technology metallurgy crystallization ganaax, iyo sidoo kale alloying micro iyo rogid la kontaroolo iyo technology qaboojinta la xakameeyey, horumariyo jiil cusub oo ah birta u adkaysta kulaylka. Birtu waxay leedahay sifooyin farsamo oo dhammaystiran oo wanaagsan, gabowga heerkulka sare ka dib xasilloonida, iyo waxqabadka alxanka iyo waxqabadka geeddi-socodku waa mid wanaagsan, oo ku habboon qaybta heerkulka sare ee qalabka.
