Chithunzi cha ASTM A335 P22chitoliro chachitsulo cha alloy ndi chinthu chofunikira kwambiri cha mafakitale chokhala ndi zinthu zabwino kwambiri monga mphamvu zambiri, kulimba kwambiri, kukana kwa dzimbiri komanso kukana kutentha kwambiri. Amagwiritsidwa ntchito kwambiri pamafuta amafuta, makampani opanga mankhwala, mphamvu zamagetsi, mafakitale a nyukiliya, ndi zina zambiri. Nkhaniyi ifotokoza za zinthu, njira zopangira, magwiridwe antchito ndi magawo ogwiritsira ntchito ASTM.A335 P22aloyi zitsulo chitoliro mwatsatanetsatane, kupereka owerenga kumvetsa mwatsatanetsatane ndi mozama.
The mankhwala ayenera kutsatira TSG D7002 kuthamanga mapaipi chigawo mtundu mayeso malamulo.
Muyezo wokhazikitsidwa:ASTMA335/A335Mmkulu kutentha chitsulo mtengo aloyi zitsulo Seamless zitsulo chitoliro mfundo

Choyamba, tiyeni tikambirane nkhani zaChithunzi cha ASTM A335 P22aloyi chitsulo chitoliro. Chitoliro chachitsulo ichi chimagwiritsa ntchito chitsulo chapamwamba kwambiri cha carbon structural steel kapena alloy structural chitsulo monga chopangira chachikulu ndipo chimapangidwa ndi zojambula zozizira bwino kapena kugudubuza kotentha. Kuwongolera kolondola kwa zinthu za kaboni, zinthu za aloyi ndi kufufuza zinthu mu chitoliro chachitsulo zimatsimikizira kulimba komanso kulimba kwa chitoliro chachitsulo. Kuphatikiza apo, kukana kwa dzimbiri kwa ASTM A335 P22 aloyi chitoliro chachitsulo ndikwabwino kwambiri, ndipo kumatha kukhalabe ndi magwiridwe antchito ndi moyo wautumiki kwa nthawi yayitali m'malo ovuta.
Kenako, tiyeni tiphunzire za kupanga ndondomeko yaChithunzi cha ASTM A335 P22aloyi chitsulo chitoliro. Njira yopangira zinthu makamaka imaphatikizapo maulalo ofunikira monga smelting, rolling and heat treatment. Panthawi yosungunula, zopangira zimatenthedwa kuti zisungunuke ndipo zofunikira za alloy zimawonjezeredwa kuti zipeze mankhwala ofunikira komanso mawonekedwe a alloy. Pakugubuduza ndondomeko, dimensional zolondola, pamwamba khalidwe ndi katundu makina a chitoliro zitsulo kuonetsetsa ndi ndendende kulamulira magawo monga anagubuduza kutentha, liwiro ndi mapindikidwe. Pomaliza, ulalo wa chithandizo cha kutentha umathandizira kuthetsa kupsinjika kotsalira mkati mwa chitoliro chachitsulo ndikuwongolera kukhazikika kwake komanso kukhazikika.
Makhalidwe amachitidwe aChithunzi cha ASTM A335 P22aloyi zitsulo chitoliro ndi chimodzi mwa zifukwa kutchuka kwake. Choyamba, chitoliro chachitsulo chimakhala ndi mphamvu zambiri komanso kulimba, chimatha kupirira kupanikizika kwakukulu ndi zotsatira zake, ndikukwaniritsa zofunikira zamagulu osiyanasiyana ogwira ntchito. Kachiwiri, imakhala ndi kukana kwa dzimbiri ndipo imatha kukana kukokoloka kwa zinthu zosiyanasiyana zama mankhwala kuti zitsimikizire kuti zikugwira ntchito kwanthawi yayitali. Kuphatikiza apo, ASTM A335 P22 aloyi zitsulo chitoliro alinso zabwino mkulu kutentha kukana ndi kukhalabe khola mawotchi ndi mankhwala katundu pansi pa kutentha chilengedwe.
Ndi chifukwa cha makhalidwe abwinowa kuti ASTM A335 P22 aloyi chitoliro chachitsulo chagwiritsidwa ntchito kwambiri m'madera ambiri. M'munda wa mafuta amafuta ndi mankhwala, chitoliro chachitsulo chimagwiritsidwa ntchito popanga mapaipi otentha kwambiri komanso kuthamanga kwambiri ndi zida kuti zitsimikizire chitetezo ndi kukhazikika kwa njira yopanga. M'munda wa mphamvu,Chithunzi cha ASTM A335 P22chitoliro chachitsulo cha alloy chimagwiritsidwa ntchito kwambiri pazida zazikulu monga ma boilers ndi ma superheaters, kupirira kutentha kwakukulu ndi nthunzi yothamanga kwambiri ndi madzi otentha, kupereka chitsimikizo chodalirika cha kupanga magetsi. Komanso, m'munda wa makampani nyukiliya, chitoliro zitsulo komanso mbali yofunika pa kupanga mapaipi ndi muli mu reactors nyukiliya kuonetsetsa ntchito otetezeka mphamvu nyukiliya.
Kuphatikiza pa madera omwe ali pamwambawa,Chithunzi cha ASTM A335 P22aloyi zitsulo chitoliro angathenso makonda malinga ndi zosowa kasitomala kukwaniritsa zofunika ntchito mu zochitika zenizeni. Mwachitsanzo, posintha magawo monga makulidwe a khoma, m'mimba mwake ndi kutalika kwa chitoliro chachitsulo, amatha kukwaniritsa zosowa zama projekiti osiyanasiyana. Panthawi imodzimodziyo, chitoliro chachitsulo chikhoza kuchitidwanso pamtunda malinga ndi zosowa za makasitomala, monga kupopera mankhwala odana ndi dzimbiri, galvanizing, etc., kuti apititse patsogolo kukana kwa dzimbiri ndi moyo wautumiki.
ASTM A335 P22 aloyi zitsulo chitoliro, monga chuma chuma ndi ntchito kwambiri, amatenga mbali yofunika m'madera ambiri. Ndi kupita patsogolo kosalekeza kwaukadaulo komanso kukulitsa kopitilira muyeso kwa magawo ogwiritsira ntchito, tili ndi chifukwa chokhulupirira kuti chitoliro chachitsulo cha ASTM A335 P22 chidzapitiliza kuthandizira chitukuko cha mafakitale m'tsogolomu.
