Wopanga Chitoliro Wapamwamba wa ASTM A335 P91 Wopanda Seamless Seel Pipe ku China
Mwachidule
Kukula kwathu kumadalira zida zotsogola, matalente apamwamba komanso mphamvu zamaukadaulo zolimbikitsira mosalekeza pamakampani athu apamwamba achitsulo chitoliro, tipitiliza kuyesetsa kukulitsa kampani yathu ndikugulitsa zinthu zabwino kwambiri ndimitengo yankhanza. Kufunsa kulikonse kapena ndemanga zimayamikiridwa kwambiri. Kumbukirani kutigwira mwaufulu. Kampani yathu ikugwira ntchito ndi mfundo ya "umphumphu, mgwirizano wopangidwa, wokhazikika, wopambana-wopambana". Tikukhulupirira kuti titha kukhala ndi ubale wabwino ndi wamalonda ochokera padziko lonse lapansi
P91 sikuti imangokhala ndi kukana kwa okosijeni komanso kukana kwa dzimbiri kwa kutentha kwa nthunzi, komanso imakhala ndi kulimba kwamphamvu komanso kukhazikika kwapang'onopang'ono kwanthawi yayitali komanso mphamvu zamatenthedwe. Kutentha kwautumiki kukatsika kuposa 620 ℃, kupsinjika kwake kovomerezeka kumakhala kopitilira muyeso wachitsulo chosapanga dzimbiri cha austenitic. Pamwamba pa 550 ℃, kupanikizika kovomerezeka kovomerezeka ndi pafupifupi kuwirikiza kawiri kwa T9 ndi 2.25Cr-1Mo chitsulo. Itha kugwiritsidwa ntchito ngati kutentha kwapamwamba kwambiri komanso chitoliro chachitsulo chotenthetsera kutentha kwa khoma la subcritical ndi supercritical boiler ≤625 ℃, mutu wotentha kwambiri komanso kutentha kwa khoma la nthunzi ≤600 ℃, komanso chowotcha chamagetsi a nyukiliya ndi chubu cha ng'anjo yamafuta amafuta.
Kugwiritsa ntchito
Amagwiritsidwa ntchito kwambiri popanga chitoliro chapamwamba cha aloyi chitsulo chowotcha, chitoliro chosinthanitsa kutentha, chitoliro champhamvu cha nthunzi chamafuta ndi mafakitale amafuta.
Main Grade
Kalasi ya apamwamba aloyi chitoliro: P1, P2, P5, P9, P11, P22, P91, P92 etc.
