Valavu yowunikira mbale ziwiri ya ASTM A995 6A ndi valavu yopangidwa ndi zinthu za ASTM A995 6A.

Chitsulo chosapanga dzimbiri cha ASTM A995 6A super duplex chinaonekera ngati chitsulo chopangidwa pakati pa zaka za m'ma 1980. Cholinga cha chitukuko ndikuthetsa zinthu zolimba (zomwe zili ndi chloride, CO2, H2S, ndi zina zotero) zomwe zimagwiritsidwa ntchito m'minda yamafuta ndi gasi pansi pa nyanja, m'malo molimbana ndi dzimbiri komanso kukana dzimbiri. Chitsulo chosapanga dzimbiri cha Zeron25 (25Cr-6Ni-2Mo) chosakwanira. Chitsulo cha ASTM A995 6A chagwiritsidwa ntchito m'minda yambiri, makamaka chifukwa cha mphamvu zake zapamwamba komanso kukana dzimbiri komanso kupsinjika kwa chloride. Chitsulo chili ndi nayitrogeni yambiri, yomwe imalimbitsa austenite. Ngakhale kuti zinthu za chromium ndi molybdenum zili ndi mphamvu zambiri, chifukwa cha mphamvu ya nayitrogeni, pamene kutentha kuli pamwamba pa 1050 ℃, kuchuluka kwa ferrite kumakhalabe pafupi ndi 50%.

Chifukwa cha mphamvu zake zabwino zamakina komanso kukana dzimbiri, chitsulo chosapanga dzimbiri cha duplex chagwiritsidwa ntchito kwambiri mu uinjiniya wa m'mphepete mwa nyanja komanso kupanga zombo, monga gasi wa m'mphepete mwa nyanja, machitidwe amadzi, mapampu amadzi akuya, nsanja zobowolera m'mphepete mwa nyanja, zida zamigodi ya pansi pa nyanja, zombo zankhondo ndi zombo zapadera. Ngakhale kuti ASTM A995 6A chitsulo chosapanga dzimbiri cha duplex chili ndi kukana dzimbiri kwakukulu, chikadali chinthu chosagwira ntchito mwachilengedwe, chomwe chingachepetse kuthamanga kwa dzimbiri la tizilombo toyambitsa matenda, ndipo sichingathe kuthetsa kuwonongeka komwe kumachitika chifukwa cha dzimbiri la tizilombo toyambitsa matenda chifukwa cha chifukwa chake.

Chotsegulira ndi kutseka valavu yowunikira yokhala ndi mbale ziwiri chimatsegulidwa kapena kutsekedwa ndi kayendedwe kapakati ndi mphamvu yoletsa kuyenda kwa valavu kumbuyo kuti isatchulidwe kuti valavu yowunikira. Mavalavu owunikira ndi mavalavu odziyimira pawokha, omwe amagwiritsidwa ntchito makamaka pamapaipi okhala ndi kayendedwe ka njira imodzi, zomwe zimathandiza kuti chowunikira chokha chiziyenda mbali imodzi kuti chipewe ngozi.

Valavu ya Newsway ASTM A995 6A mbali ziwiri zotsegulira/kutseka valavu zimatsegulidwa kapena kutsekedwa ndi kayendedwe kapakati ndi mphamvu kuti cholumikiziracho chisabwerere mmbuyo. Mavavu awiri owunikira ndi a gulu la mavavu odziyimira okha, omwe amagwiritsidwa ntchito makamaka pamapaipi okhala ndi kayendedwe ka njira imodzi, ndipo amangolola kuti cholumikiziracho chiyende mbali imodzi kuti apewe ngozi. Cholumikizira cha gulugufe cha valavu yowunikira ndi ma semicircles awiri, ndipo kasupe amagwiritsidwa ntchito kukakamiza kubwezeretsanso. Malo otsekera akhoza kukhala cholumikizira cha thupi chomwe sichingawonongeke kapena chotchingira rabara. Chili ndi ntchito zambiri komanso chotchingira chodalirika.
