Fakitale ya OEM ya Carbon Steel Seamless Pipe Alloy Steel Pipe ASTM A335 Iron chube
Kufotokozera Kwachidule:
ASTM A335 nthawi zambiri imatchedwa chrome moly pipe chifukwa cha mankhwala omwe ali ndi Molybdenum (Mo) ndi Chromium (Cr).Molybdenum imawonjezera mphamvu yachitsulo ndipo Chromium (kapena chrome) ndiye chinthu chofunikira kwambiri chachitsulo chosapanga dzimbiri.Chitoliro chachitsulo cha chrome moly alloy chimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito m'mafakitale amagetsi, malo oyeretsera, malo opangira mafuta amafuta, ndi ntchito zamafuta komwe madzi ndi mpweya zimatengera kutentha kwambiri komanso kupanikizika.
Ndi udindo wathu kukwaniritsa zosowa zanu ndikukupatsani mwaluso.Chisangalalo chanu ndi malipiro athu abwino.Tikuyang'ana kutsogolo kuti tiyime ndi chitukuko chophatikizana cha OEM Factory ya Carbon Steel Seamless Pipe Alloy Steel Pipe ASTM A335 Iron Tube, Njira yathu yapaderadera imathetsa kulephera kwa gawoli ndipo imapatsa makasitomala athu mawonekedwe apamwamba osasinthika, kutilola kuwongolera mtengo. , konzekerani mphamvu ndikusunga nthawi yopereka nthawi.
Ndi udindo wathu kukwaniritsa zosowa zanu ndikukupatsani mwaluso.Chisangalalo chanu ndi malipiro athu abwino.Tikuyembekezera kuyimitsa kwa mgwirizano wa chitukukoChina Seamless Carbon Steel chubu ndi Seamless Steel Pipe, Tikupereka mayankho abwinoko ndi mapangidwe osiyanasiyana komanso ntchito zoyenerera.Nthawi yomweyo, landirani OEM, maoda a ODM, itanani anzanu kunyumba ndi kunja pamodzi chitukuko chofanana ndikupeza kupambana, kukulitsa kukhulupirika, ndikukulitsa mwayi wamabizinesi!Ngati muli ndi funso lililonse kapena mudzafunika zambiri onetsetsani kuti omasuka kulankhula nafe.Takhala tikuyembekezera kulandira mafunso anu posachedwa.
Kukana mwamphamvu kuphulika pa kutentha kwakukulu ndi kupanikizika kwakukulu.
Itha kugwiritsidwa ntchito ngati Hydrogen sulfide Corrosion Services.
Kukana kusweka kwa hydrogen kuukira ndi embrittlement.
Kulimbana ndi kutentha kwa dzimbiri kwa sulfide.
Itha kugwiritsidwa ntchito pa Mapulogalamu a NACE pomwe malo owawa ali pansi pa kutentha kwambiri komanso kupanikizika.
Itha kugwiritsidwa ntchito mu NACE-MRO 175 Sour Service.
Oyenera ntchito zokwawa rupture.
Imatha kupirira kutentha kwambiri ndi elasticity yotsika kwambiri.
Mitundu yazitsulo za alloy zomwe zimakutidwa ndi ASTM A335 - ASME SA335 zidapangidwa ndi prefix "P", kuyambira P5 mpaka P92.Magiredi P11/P22 ndi P91/92 nthawi zambiri amapezeka m'malo opangira magetsi, pomwe giredi P5 ndi P9 ndizofala kwambiri pamakampani opanga mafuta.Magiredi P9, P91 ali, pamndandanda, okwera mtengo kwambiri
