Kukula kwa ASTM A192
Kunja Diameter: 12.7-177.8mm1/2-7 pa.]
Kuchuluka kwa khoma: 2.2-25.4mm [0.085 -1in.]
Machubu okhala ndi miyeso ina atha kuperekedwa, malinga ngati machubu oterowo atsatira zofunikira zina zamtunduwu.
Kupanga
Machubu adzakhala opanda msoko komanso otentha kapena ozizira ntchito monga ananenera Processing.
ASTM A192 ndi njira ziwiri zazikulu zopangira chitoliro chachitsulo chosasunthika: chokoka chozizira komanso chozungulira chotentha.
Kutentha Chithandizo
Kutentha kumatenthedwa pa 1200 ℉ [650 ℃] kapena kupitilira apo mutatha kuzizira komaliza.

Zowonjezera Processing
Mukagula ndikugwiritsa ntchito chitoliro cha ASTM A192, malo ogwiritsira ntchito kumapeto ndi zofunikira za ogwiritsa ntchito zingafunike kukonza kowonjezera:
Kupaka kapena Kupaka
Utoto wopanda dzimbiri kapena zokutira zina zoteteza zitha kugwiritsidwa ntchito pamwamba.Zopaka izi zimapereka chitetezo ku dzimbiri, makamaka ngati chubu la boiler likukumana ndi chinyezi.
Mankhwala oletsa dzimbiri
Kuphatikiza pa kupenta, mankhwala ena odana ndi dzimbiri monga galvanizing, aluminizing, kapena kupaka ndi zinthu zina zotsutsana ndi dzimbiri zingagwiritsidwe ntchito kuti zithandize kuonjezera kulimba kwa chubu m'madera ovuta.
Kutentha Chithandizo
Ngakhale ASTM A192 imatchula zofunikira popanga ndi kuyesa chitoliro, muzinthu zina zowonjezera zowonjezera kutentha (mwachitsanzo, normalizing, annealing) zingafunikire kukwaniritsa makina kapena kukonzanso microstructure ya chitoliro.
Zamkati ndi Zakunja Zapamwamba Amamaliza
Mkati ndi kunja kwa machubu otenthetsera angafunikire kupukuta, kupukutidwa, kapena kutsukidwa kuti apititse patsogolo kuyenda kwamadzimadzi kapena ukhondo.
Kumaliza Machining
Kutengera zomwe zimafunikira pakuyika ndi kulumikiza, malekezero a machubu a boiler angafunikire ulusi, kuwongoleredwa, kapena kupangidwa mwanjira ina kuti athandizire kukhazikitsa.
Kuyendera kowonjezera
Kuwonetsetsa kuti machubu akukumana ndi ASTM A192 komanso zofunikira zokhudzana ndi kasitomala, kuwunika kowonjezera kutha kuchitidwa.Mwachitsanzo, kuyesa kwa akupanga, kuyesa kwa X-ray, ndi zina.
Kugwiritsa Ntchito Mwachindunji
Okhazikika mu boiler yachitsulo chosasunthika komanso machubu apamwamba kwambiri.Machubuwa amagwiritsidwa ntchito makamaka pazithandizo zothamanga kwambiri monga ma boilers othamanga kwambiri, ma boiler okwera kwambiri, ndi zida zomwe zimagwira ntchito m'malo otentha kwambiri komanso opanikizika kwambiri.
Zotsatirazi ndi ntchito za ASTM A192 zitsulo chitoliro ntchito:
Ma boilers othamanga kwambiri
Machubu opanda msoko a ASTM A192 ndi oyenera kupanga machubu apamwamba kwambiri, machubu otenthetsera madzi otentha, machubu a nthunzi, machubu akulu, ndi zina zambiri, zama boiler amadzi othamanga kwambiri komanso kupitilira apo.Zomwe zimagwiritsidwa ntchito m'malo opangira magetsi, mafakitale ogulitsa mafakitale ndi migodi ndi zida zamagetsi, zomwe zimagwiritsidwa ntchito popanga kutentha kwakukulu ndi nthunzi yothamanga kwambiri.
Ma boilers okwera kwambiri
Machubu a ASTM A192 amagwiritsidwa ntchito kwambiri pamagetsi apamwamba kwambiri (omwe nthawi zambiri amatchedwa ma boiler omwe ali ndi zovuta zogwira ntchito pamwamba pa 9.8 MPa).Ma boiler awa nthawi zambiri amagwiritsidwa ntchito m'malo akuluakulu opangira magetsi.
Superheaters ndi reheaters
Izi ndi zigawo zikuluzikulu za boiler ndipo zimagwiritsidwa ntchito kuonjezera kutentha kwa nthunzi, zomwe zimawonjezera mphamvu ya kutentha kwa dongosolo lonse.
Zosintha kutentha
Ngakhale ASTM A192 imagwiritsidwa ntchito makamaka pamachubu otenthetsera, itha kugwiritsidwanso ntchito posinthanitsa ndi kutentha komwe kumafunika kutengera kutentha kwabwino, makamaka m'malo otentha kwambiri, opanikizika kwambiri.
Maboiler a Mafuta Otentha
Mu boiler wamtunduwu, mphamvu zotentha zimasamutsidwa ndikuwotcha mafuta otenthetsera, omwe amagwiritsidwa ntchito kwambiri m'mafakitale opangira mankhwala, kukonza chakudya, ndi nsalu.Astm a192 chubing ndi yoyenera kutentha kwambiri, kupanikizika kwambiri komwe kumapezeka muzogwiritsa ntchito izi.
Miyezo Yoyenera
ASTM A192: Kwa machubu osakanizika a zitsulo za kaboni osasunthika pama boiler othamanga kwambiri.
Chithunzi cha ASTM A179: Chosinthira chotenthetsera chachitsulo chosasunthika chosasunthika komanso machubu a condenser amikhalidwe yotsika kwambiri.
ASTM A210: Seamless medium carbon steel boiler and superheater chubu.
ASTM A213: Chowotcha chachitsulo chosasinthika cha ferritic ndi austenitic alloy, superheater, ndi machubu osinthira kutentha.
Chithunzi cha ASTM A106: Msokonezo machubu zitsulo mpweya ntchito mkulu-kutentha.
Chithunzi cha ASTM A335: Machubu achitsulo osasunthika a ferritic ndi austenitic alloy ndi mapaipi a ntchito zotentha kwambiri, mwachitsanzo malo opangira magetsi.
Chithunzi cha ASTM A516: Mpweya wachitsulo wa kaboni yoyenera zombo zapakatikati komanso zotsika kutentha.
ASTM A285: Mbale yachitsulo ya carbon yoyenera zombo zotsika mpaka zapakatikati.
ASTM A387: Aloyi mbale zitsulo ntchito popanga ma boilers welded ndi zotengera kuthamanga, makamaka kumene kukana kutentha kwambiri kumafunika.
Chithunzi cha ASTM A53: Machubu achitsulo akuda ndi otentha osakanizidwa komanso osasunthika azitsulo zamitundu yonse komanso zamakina.
Pamodzi, miyeso iyi imakhudza zinthu zakuthupi, kulolerana kwa mawonekedwe, mawonekedwe amakina, ndi zida zamakina zomwe zimafunikira kuti zigwiritsidwe ntchito mu ma boilers, zotengera zopondereza, zosinthira kutentha, ndi zina zambiri, pa kutentha kosiyanasiyana, kupsinjika, komanso magwiridwe antchito.
