Zofunikira Zochizira Kutentha
Chithunzi cha ASTM A106
Ayenera kutenthedwa ndi kutentha, kawirikawiri ndi normalizing (njira yowotchera pamwamba pa kutentha kwakukulu ndi kuzizira mpaka kutentha kwapakati).
Hot adagulung'undisa chitoliro: sikutanthauza kutentha mankhwala.Chitoliro chotenthedwa chikatenthedwa, chiyenera kutenthedwa pa 1200 ° F [650 ° C] kapena kupitirira apo.
Chitoliro chozizira: chiyenera kutenthedwa pa kutentha kwa 1200 ° F [650 ° C] kapena kupitirira apo pambuyo pojambula chozizira chomaliza.
Chithunzi cha ASTM A53
Type E, Grade B, and Type F, Grade B: iyenera kutenthedwa ndi kutentha pambuyo pa kuwotcherera mpaka 1000 ° F [540 ° C] kuti pasakhale martensite yosasunthika yomwe ilipo, kapena kuchitiridwa mwanjira ina kuti pasakhale martensite osasunthika.
Mtundu S: Chithandizo cha kutentha sikofunikira pa chitoliro chopanda msoko.
Chemical Components
Mukasanthula machubu a ASTM A53 ndi ASTM A106, pali kusiyana kwakukulu komwe kungadziwike.ASTM A106 imatchula za silicon (Si) zosachepera 0.10%, zomwe zimathandizira kuti zigwire ntchito pa kutentha kwakukulu, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito kumalo otentha kwambiri monga omwe ali m'makampani a petrochemical ndi machitidwe otumizira nthunzi.
Pazinthu za carbon (C), muyezo wa ASTM A53 umatchula malire otsika kwambiri, makamaka a magiredi A ndi B a Mtundu wa S ndi Mtundu E. Izi zimapangitsa kuti machubu a Type A53 akhale oyenera kuwotcherera ndi kuzizira ndipo motero amagwiritsidwa ntchito nthawi zambiri pomanga ndi madzimadzi. machitidwe oyendera, monga mapaipi amadzi ndi gasi.
Pankhani ya manganese (Mn), ASTM A106 imapereka mitundu yosiyanasiyana ya Gulu B ndi C, yomwe imalola kusinthasintha kochulukira popanga ndikuwongolera mphamvu.Chitoliro cha A53, komano, chimangokhala ndi malire ocheperako a manganese, omwe amathandizira kukhazikika pakuwotcherera.

Komabe, ASTM A106 Grade C imayika mipiringidzo kukhala yokwera, kutanthauza kuti imapereka magwiridwe antchito apamwamba kwambiri, monga kupanikizika kwambiri kapena kutentha.
Zowonjezera zamakina izi zimapangitsa Gulu C kukhala loyenera kwambiri pamafakitale apadera omwe amafunikira zida zonyamula katundu komanso kulimba.
