Mu dziko la mainjiniya a mafakitale, kufunikira kwa njira zodalirika komanso zolimba zopalira mapaipi kukupitirira kukula. Pofuna kuthana ndi vutoli, tsamba lathu lawebusayiti limapereka mapaipi ambiri achitsulo chapamwamba kwambiri, kuphatikizapo mapaipi olemekezeka.ASTM A335 P91, P5, P9, ndi zina zosiyanasiyana, kuti zikwaniritse zofunikira zosiyanasiyana zamafakitale.
Pakati pa zinthu zathu zosiyanasiyana, chitoliro cha ASTM A335 P91 chimaonekera ngati chimodzi mwa zinthu zomwe anthu ambiri amasankha. Chodziwika bwino chifukwa cha mphamvu zake zapamwamba kutentha komanso kukana dzimbiri, chakhala njira yabwino kwambiri yogwiritsira ntchito boiler. Mapaipi athu a ASTM A335 P91 amatsimikizira kuti amagwira ntchito bwino kwambiri ngakhale atakhala ndi mphamvu zambiri komanso kutentha kwambiri, zomwe zimapangitsa kuti akhale chisankho chabwino kwambiri pa ntchito zofunika kwambiri m'mafakitale.
Kwa iwo omwe akufuna kusinthasintha kwapamwamba komanso kulimba, chitoliro chachitsulo cha ASTM A335 P5 ndi njira yabwino kwambiri. Chitoliro chachitsulo chopanda msoko ichi chili ndi kuthekera kolumikizana bwino komanso kupangika bwino, zomwe zimapangitsa kuti chikhale chodziwika bwino pa ntchito zosiyanasiyana, kuyambira machitidwe a boiler mpaka mapaipi otentha kwambiri.
Chitoliro cha ASTM A335 P9 ndi chinthu china chamtengo wapatali chomwe chili m'gulu lathu, chomwe chimatchuka chifukwa cha kukongola kwake komanso kukana kusungunuka kwa okosijeni ndi kukula kwa zinthu pa kutentha kwakukulu. Chimagwiritsidwa ntchito kwambiri m'mafakitale opanga magetsi ndi mafakitale a petrochemical chifukwa cha kuphatikiza kwake kosayerekezeka kwa mphamvu ndi kulimba.
Pa webusaiti yathu, tikumvetsa kuti mapulojekiti osiyanasiyana amafuna zofunikira zinazake, ndichifukwa chake timaperekansoChitoliro cha ASTM A213.
Chitoliro cha ASTM A213, chopangidwa kuti chizitha kupirira kutentha kwambiri komanso kuwononga chilengedwe, ndi chisankho chabwino kwambiri pakugwiritsa ntchito komwe kumafunika magwiridwe antchito osasokonekera.
Kudzipereka kwathu pakuchita bwino sikupitirira mtundu umodzi wa malonda. Pa ntchito zokhazikika, timaperekaChitoliro cha ASTM A106, njira yosinthika yodziwika bwino chifukwa cha kumalizidwa kwake kosalala komanso kulondola kwake kopanda cholakwika.
Monga malo amodzi operekera mapaipi achitsulo chopangidwa ndi alloy, timanyadira kupereka chitoliro chachitsulo chopangidwa ndi alloy cha 15crmo, chodziwika bwino chifukwa cha mphamvu zake zokoka komanso kukana kuwonongeka. Chitolirochi ndi chisankho chomwe chimakondedwa kwambiri pamapulojekiti omwe amafuna kulimba komanso kugwiritsa ntchito ndalama zochepa.
Kuwonjezera pa zinthu zomwe tatchulazi, timaperekanso mitundu yambiri ya mapaipi a P5 alloy, mapaipi a P9 alloy, ndi mapaipi achitsulo a T91 alloy, chilichonse chopangidwa kuti chikwaniritse zofunikira zamakampani.
Pa webusaiti yathu, timaika patsogolo kukhutitsidwa kwa makasitomala ndipo timachita zonse zomwe tingathe kuti tipereke zinthu zabwino kwambiri komanso utumiki wabwino kwambiri. Popeza tili ndi mbiri yopereka zinthu pa nthawi yake komanso mitengo yabwino, tapeza chidaliro cha makasitomala ambiri padziko lonse lapansi.
Pomaliza, pankhani yopezera zinthumapaipi achitsulo cha alloy champhamvu kwambiri, tsamba lathu lawebusayiti likadali malo abwino kwambiri opitira. Ndi mitundu yosiyanasiyana ya zinthu zathu, kuphatikizapo mapaipi a ASTM A335 P91, P5, P9, ndi mapaipi ena apamwamba achitsulo, tikupitilizabe kupatsa mphamvu mafakitale ndi mayankho odalirika omwe amatha kupirira mayeso a nthawi ndi mikhalidwe yovuta.
