317L Chubu Chachitsulo chosapanga dzimbiri

DESCRIPTION

Chitsulo chosapanga dzimbiri 317L ndi giredi ya molybdenum yokhala ndi mpweya wochepa, komanso zowonjezera za chromium, faifi tambala, ndi molybdenum. Izi zimapereka kukana kwa dzimbiri bwino komanso kuchulukitsidwa kukana kuukira kwamankhwala kuchokera ku acetic, tartaric, formic, citric, ndi sulfuric acid. 317L machubu/mapaipi amapereka kukwawa kwakukulu, komanso kukana kukhudzidwa akamatenthedwa, chifukwa chokhala ndi mpweya wochepa. Zopindulitsa zowonjezera zimaphatikizapo kupsinjika kwa kukana kuphulika, ndi mphamvu yamphamvu pa kutentha kwakukulu. Mapaipi achitsulo a Giredi 317l sakhala ndi maginito m'malo opindika. Komabe, pambuyo kuwotcherera pang'ono maginito akhoza kuwonedwa.

317L NTCHITO ZA ZITSANI ZOSAWONA

Machubu achitsulo osapanga dzimbiri a 317L operekedwa ndi Arch City Steel & Alloy ali ndi izi:

Kulimbana ndi Corrosion:

  • Imawonetsa kukana kwa dzimbiri kwapadera m'malo osiyanasiyana, makamaka m'malo acidic chloride ndi mankhwala osiyanasiyana.
  • Kukana kwa dzimbiri kwabwino pamapulogalamu omwe kuipitsidwa kochepa kumafunikira
  • 317L chitsulo chosapanga dzimbiri chubu / chitoliro chokhala ndi mpweya wochepa chimapereka kukana kwabwino kwa intergranular corrosion
  • Chizoloŵezi chachitsulo chobisala chikakumana ndi chlorides, bromides, phosphorous acids, ndi iodides chimaponderezedwa.

Kulimbana ndi Kutentha:

  • Kukana kwabwino kwa okosijeni chifukwa cha chromium-nickel-molybdenum.
  • Imawonetsa kutsika kocheperako pakutentha mpaka 1600-1650 ° F (871-899 ° C), mumlengalenga wamba.

Makhalidwe Owotcherera:

  • Kupatula kuwotcherera kwa oxyacetylene, kuwotcherera bwino ndi maphatikizidwe onse wamba ndi njira zokana.
  • Chitsulo chodzaza ndi nickel-base komanso chromium yokwanira ndi molybdenum ziyenera kugwiritsidwa ntchito powotcherera chitsulo cha Type 317L. Izi zimathandiza kukulitsa kukana dzimbiri kwa welded mankhwala. AWS E317L/ER317L kapena austenitic, zitsulo zotsika kaboni zodzaza molybdenum zomwe zili ndi molybdenum kuposa giredi 317L zitha kugwiritsidwanso ntchito.

Kuthekera:

  • Kugwira ntchito pa liwiro lotsika ndi zakudya zokhazikika kumathandizira kuchepetsa chizolowezi cha mipope ya grade 317L kuti ikhale yolimba.
  • Mapaipi achitsulo osapanga dzimbiri a Giredi 317L ndi olimba kuposa 304 osapanga dzimbiri ndipo amakhala ndi chip chachitali komanso chazingwe akapangidwa. Chifukwa chake, kugwiritsa ntchito chip breakers kumalimbikitsidwa.

Mapulogalamu:

Machubu a zitsulo zosapanga dzimbiri a Giredi 317L amagwiritsidwa ntchito ponyamula mowa, utoto wa asidi, bleaching solution, acetylating and nitrating mixs, etc. Ntchito zina za kalasi 317L machubu ndi mapaipi ndi monga:

  • Zida zamagetsi ndi petrochemical processing
  • Zida zogwiritsira ntchito mapepala ndi zamkati
  • Zida zopangira chakudya
  • Ma condensers m'malo opangira zida za nyukiliya ndi zinthu zakale
  • Zida zopangira nsalu
