Chiyambi: Mapaipi achitsulo chopanda msoko ndi zinthu zofunika kwambiri mumakampani opanga ma boiler, zomwe zimapereka njira zothanirana ndi kutentha kwambiri komanso kupsinjika kwa ntchito zosiyanasiyana. Mapaipi awa amagwirizana ndi miyezo yokhwima yomwe yakhazikitsidwa ndi ASTM A335, yokhala ndi magiredi mongaP5, P9, ndi P11, kuonetsetsa kuti boiler ikugwira ntchito bwino kwambiri, kulimba, komanso kudalirika.

Miyezo ya ASTM A335ASTM A335 ndi chitoliro chomwe chimaphimba chitoliro cha ferritic alloy-steel chopanda msoko kuti chigwiritsidwe ntchito kutentha kwambiri. Chimadziwika kwambiri ndipo chimagwiritsidwa ntchito mumakampani opanga boiler chifukwa cha zofunikira zake zolimba pamakina, kapangidwe ka mankhwala, ndi njira zoyesera. Miyezo iyi ndi yofunika kwambiri pakuwonetsetsa kuti mapaipi achitsulo a alloy omwe amagwiritsidwa ntchito ndi abwino komanso otetezeka.boiler yothamanga kwambiri komanso yotentha kwambirimachitidwe.

Zipangizo ndi Magiredi: Mapaipi achitsulo a alloy amapezeka m'magiredi osiyanasiyana, kuphatikizapo P5, P9, ndi P11, iliyonse yopangidwa kuti ikwaniritse zofunikira pa kutentha ndi kuthamanga kwa mpweya. P5 imapereka kukana bwino dzimbiri, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pa kutentha kwapakati mpaka kwakukulu. P9 imadziwika ndi mphamvu zake zapadera komanso kulimba, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pa malo ophikira boiler ovuta. P11 ili ndi mphamvu yowonjezera yogwira ntchito komanso kukana kutentha, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pa kutentha kwambiri.

Ubwino: Mapaipi achitsulo chopanda msoko ali ndi ubwino wambiri womwe umawapangitsa kukhala chisankho chabwino kwambiri mumakampani opanga ma boiler. Choyamba, kapangidwe kake kopanda msoko kamachotsa chiopsezo cha kutuluka kwa madzi, ndikutsimikizira kuti boiler ikugwira ntchito bwino komanso moyenera. Zinthu zomwe zimaphatikiza ma alloy m'mapaipi awa zimawonjezera kukana kwawo ku okosijeni ndi kukula, ndikusunga umphumphu wawo ngakhale m'mikhalidwe yovuta kwambiri. Kuthekera kwa mapaipi kupirira kusinthasintha kwa kuthamanga kwa mpweya ndi kutentha popanda kusintha kapena kulephera kumathandiza kuti azikhala nthawi yayitali komanso kuti asafunike kukonza kwambiri.

Mapulogalamu: Mapaipi achitsulo opanda msoko, ogwirizanaMiyezo ya ASTM A335, amagwiritsidwa ntchito kwambiri m'maboiler osiyanasiyana. Amagwiritsidwa ntchito kwambiri m'mafakitale opanga magetsi, komwe amagwira ntchito ngati zinthu zofunika kwambiri pa ma superheater, ma reheater, ndi ma waterwater waters. Makampani opanga mafuta ndi gasi amadaliranso mapaipi awa pa mapaipi a nthunzi ndi mayunitsi opangira kutentha kwambiri. Kuphatikiza apo, amagwiritsidwa ntchito m'mafakitale oyeretsera ndi mafakitale a petrochemical pa ntchito zomwe zimafuna kutentha kwambiri komanso kukana kupanikizika.

Pomaliza: Pomaliza, mapaipi achitsulo chopanda msoko omwe akugwirizana ndiMiyezo ya ASTM A335ndipo ali ndi magulu P5, P9, ndi P11 amapereka mayankho ofunikira kwambiri kwa makampani opanga ma boiler. Chifukwa cha makhalidwe awo apadera, mapaipi awa amatsimikizira kuti ma boiler amagwira ntchito bwino komanso modalirika, zomwe zimapangitsa kuti akhale chisankho chabwino kwambiri pakugwiritsa ntchito kutentha kwambiri komanso kuthamanga kwambiri. Kugwiritsa ntchito kwawo m'magawo osiyanasiyana amakampani kumatsimikizira kudalirika kwawo, kulimba, komanso kuthekera kwawo kupirira zovuta kwambiri, zomwe zimapangitsa kuti akhale gawo lofunikira kwambiri la makina amakono a boiler.
