II. Kusanthula Kwatsatanetsatane kwa Muyezo Uliwonse

1. ASTM A179 / ASME SA179–Machubu Osinthira Kutentha ndi Ma Condenser

ASTM A179zophimbamachubu achitsulo chopanda mpweya wozizira omwe amakokedwa mosavutayopangidwira makamakazosinthira kutentha, zoziziritsa kutentha, ndi zida zina zofanana zotumizira kutentha.

Zinthu Zofunika KwambiriChitsulo chopanda mpweya wokwanira (kuchuluka kwa mpweya 0.06%–0.18%)

Katundu Wofunika wa Makina:

Mphamvu Yokoka: ≥325 MPa

Mphamvu Yotulutsa: ≥180 MPa

Kutalika: ≥35%

Mapulogalamu Odziwika:

Zosinthira kutentha za chipolopolo ndi chubu

Zokondetsa pamwamba

Makina otenthetsera madzi odyetsa

Zipangizo zosamutsira kutentha m'mafakitale a petrochemical ndi fillers

Ubwino wa A179: Kuchuluka kwa mpweya wochepa kumaperekamphamvu zabwino kwambiri zopindika ozizira, kuthekera koyatsa ma tube end, komanso makina abwinoChifukwa cha kuchuluka kwa mpweya wochepa, kusinthasintha kwa kutchinjiriza ndikwabwino kwambiri, zomwe zimapangitsa kuti ikhale chisankho chotsika mtengo kwambiri pazida zosamutsira kutentha.A179 ndi A192 ndi "mahatchi ogwira ntchito" pa ntchito ya boiler yotsika ndi yapakati.

2. ASTM A192 / ASME SA192–Chitsulo Choyezera Boiler Chopanikizika Kwambiri

ASTM A192zophimbamachubu a boiler a chitsulo cha kaboni chopanda msoko kuti agwiritsidwe ntchito ndi mphamvu yamagetsindipo ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri mu ma boiler amagetsi ndi mafakitale.

Zinthu Zofunika KwambiriChitsulo cha kaboni (kuchuluka kwa kaboni 0.06%–0.18%)

Katundu Wofunika wa Makina:

Mphamvu Yokoka: ≥325 MPa

Mphamvu Yotulutsa: ≥180 MPa

Kutalika: ≥35%

Kulimba: ≤137 HBW (77 HRB)

Mapulogalamu Odziwika:

Machubu a makoma a madzi

Machubu a Economizer

Magawo opanga nthunzi

Ma superheater otsika kutentha

Kusiyana kwakukulu pakati pa A192 ndi A179: A192 ikuperekakulolerana kokhwima kwa makulidwe a khomandipo ndi yoyenerantchito zapamwamba kwambiri za boiler yopaka mphamvuPamene kupanikizika kwa kapangidwe kake kupitirira malire a A179, A192 ndiye njira yabwino kwambiri yosinthira. Zonsezi zimakhala ndi kapangidwe ka mankhwala ndi mphamvu zofanana, koma A192 ili ndi zofunikira zolimba kwambiri pakupanga ndi kuwunika.

3. ASTM A210 / ASME SA210–Boiler ya Chitsulo cha Mpweya Wapakati ndi Machubu a Superheater

ASTM A210zophimbaboiler yachitsulo chapakati-kaboni ndi machubu a superheater opanda msokondipo imapereka mphamvu ziwiri:Giredi A1ndiGiredi C.

Zinthu Zofunika KwambiriChitsulo chapakati cha kaboni

Giredi A1: Kuchuluka kwa mpweya m'thupi pafupifupi 0.27%

Giredi C: Kuchuluka kwa mpweya wa kaboni pafupifupi 0.35%

Katundu Wofunika wa Makina:

Giredi	Kulimba kwamakokedwe	Mphamvu Yopereka	Kuuma
A210 Giredi A1	≥415 MPa	≥255 MPa	≤143 HBW
A210 Giredi C	≥485 MPa	≥275 MPa	≤179 HBW

Mapulogalamu Odziwika:

Mapaipi a dongosolo la boiler

Machubu a Superheater

Mapaipi a nthunzi otentha kwambiri

Ubwino Waukulu wa A210: Kaboni wapakati umaperekamphamvu yapamwamba komanso kukana kutenthaGiredi C imapereka mphamvu zoposa pafupifupi 50% kuposa A179/A192, zomwe zimapangitsa kuti ikhale yoyenera kutentha ndi kupsinjika kwakukulu. Komabe,kuwotcherera ndi kukonza chitsulo chapakati-kaboni kumafuna kuwongolera mosamala kwambiriA210 ndi yoyenera ma boiler ndi ma superheater okhala ndi kutentha kwa kapangidwe kake ka400°C–450°C.

4. ASTM A213 / ASME SA213–Chitsulo cha Alloy ndi Machubu a Chitsulo Chosapanga Dzimbiri

ASTM A213zophimbamachubu opanda msoko a ferritic ndi austenitic alloy-steelchifukwa chaboiler, superheater, ndi heat exchangermagawo otentha kwambiri.

Zipangizo Zoyambira: Chitsulo chopangidwa ndi aloyi / chitsulo chosapanga dzimbiri

Ma alloys a Ferritic: T11, T12, T22, T91, T92, ndi zina zotero.

Zitsulo zosapanga dzimbiri za AusteniticTP304H, TP347H, ndi zina zotero.

Katundu Wofunika wa Makina:

Giredi	Kulimba kwamakokedwe	Mphamvu Yopereka	Ntchito Yachizolowezi
T11(1.25Cr-0.5Mo)	≥415 MPa	≥170 MPa	Makoma a madzi a boiler, ma superheaters
T12(1Cr-0.5Mo)	≥415 MPa	≥205 MPa	Makoma a madzi a boiler, zinthu zoteteza chuma
T22(2.25Cr-1Mo)	≥415 MPa	≥205 MPa	Maboiler, malo oyeretsera zinthu zotentha kwambiri
T91(9Cr-1Mo-V)	≥585 MPa	≥415 MPa	Ma boiler a siteshoni yamagetsi ofunikira kwambiri

Mapulogalamu Odziwika:

Makoma a madzi a boiler

Akatswiri azachuma

Zotenthetsera

Mapaipi a nthunzi

Zipangizo zoyeretsera zinthu zotentha kwambiri

Mtengo Wapakati wa A213Kuwonjezera kwa chromium (Cr) ndi molybdenum (Mo) kumaperekakukana kwabwino kwambiri kwa okosijeni ndi kukana kukwawa pa kutentha kwakukuluT22 imatha kugwira ntchito kwa nthawi yayitali pa540°C–580°C, pomwe T91/T92 ingagwiritsidwe ntchito pamwambapa600°Cza mayunitsi ofunikira kwambiri. Ngati zitsulo za kaboni (A179/A192/A210) sizingakwaniritse zofunikira za mphamvu ya kutentha kwambiri, zitsulo za alloy za A213 ndi chisankho chosapeŵeka.
