Okokuqala, ake sixoxe ngezinto eziphatheleneI-ASTM A335 P22ipayipi lensimbi ye-alloy. Leli payipi lensimbi lisebenzisa insimbi yesakhiwo sekhabhoni esezingeni eliphezulu noma insimbi yesakhiwo se-alloy njengezinto eziyinhloko zokusetshenziswa futhi lenziwa ngokudweba okubandayo okuqondile noma inqubo yokugoqa eshisayo. Ukulawulwa okunembile kokuqukethwe kwekhabhoni, izakhi ze-alloy kanye nezakhi zokulandelela epayipini lensimbi kuqinisekisa amandla aphezulu nokuqina kwepayipi lensimbi. Ngaphezu kwalokho, ukumelana nokugqwala kwepayipi lensimbi ye-alloy ye-ASTM A335 P22 nakho kuhle kakhulu, futhi lingagcina ukusebenza kwalo kanye nokuphila kwenkonzo isikhathi eside ezindaweni ezinzima.
Okulandelayo, ake sifunde ngenqubo yokukhiqizaI-ASTM A335 P22ipayipi lensimbi ye-alloy. Inqubo yokukhiqiza ihlanganisa ikakhulukazi izixhumanisi ezibalulekile njengokuncibilikisa, ukugoqa kanye nokwelashwa kokushisa. Ngesikhathi senqubo yokuncibilikisa, izinto zokusetshenziswa ziyashiswa zibe sesimweni esincibilikisiwe futhi izinto ezidingekayo ze-alloy ziyangezwa ukuze kutholakale ukwakheka kwamakhemikhali okudingekayo kanye nesakhiwo se-alloy. Ngesikhathi senqubo yokugoqa, ukunemba kobukhulu, ikhwalithi yobuso kanye nezakhiwo zemishini zepayipi lensimbi kuqinisekiswa ngokulawula ngokunembile imingcele efana nokushisa kokugoqa, isivinini kanye nokuguquguquka. Okokugcina, isixhumanisi sokwelashwa kokushisa sisiza ukuqeda ukucindezeleka okusele ngaphakathi kwepayipi lensimbi futhi kuthuthukise ukuzinza nokuqina kwayo.
Izici zokusebenza zeI-ASTM A335 P22Ipayipi lensimbi elixutshwe ne-alloy nalo lingenye yezizathu zokuthandwa kwalo. Okokuqala, ipayipi lensimbi linamandla aphezulu nokuqina, lingamelana nokucindezela okuphezulu kanye nomthelela, futhi lihlangabezane nezidingo zezimo zokusebenza ezahlukahlukene eziyinkimbinkimbi. Okwesibili, linokumelana okuhle kokugqwala futhi lingamelana nokuguguleka kwezinto zamakhemikhali ezahlukahlukene ukuqinisekisa ukusebenza okuzinzile kwesikhathi eside. Ngaphezu kwalokho, ipayipi lensimbi elixutshwe ne-ASTM A335 P22 nalo linokumelana okuhle nokushisa okuphezulu futhi lingagcina izakhiwo ezizinzile zemishini kanye namakhemikhali ngaphansi kwendawo yokushisa okuphezulu.
Kungenxa yalezi zici zokusebenza ezinhle kakhulu ukuthi ipayipi lensimbi ye-ASTM A335 P22 lisetshenziswe kabanzi emikhakheni eminingi. Emkhakheni wemboni kaphethiloli namakhemikhali, ipayipi lensimbi lisetshenziselwa ukukhiqiza amapayipi nemishini yokushisa okuphezulu kanye nokucindezela okuphezulu ukuqinisekisa ukuphepha nokuzinza kwenqubo yokukhiqiza. Emkhakheni wamandla,I-ASTM A335 P22Ipayipi lensimbi elihlanganisiwe lisetshenziswa kabanzi emishinini ebalulekile efana nama-boiler nama-superheater, ebekezelela amazinga okushisa aphezulu kanye nomusi ophakeme kanye namanzi ashisayo, okunikeza isiqinisekiso esithembekile sokukhiqizwa kwamandla. Ngaphezu kwalokho, emkhakheni wemboni yenuzi, ipayipi lensimbi lidlala indima ebalulekile ekukhiqizweni kwamapayipi neziqukathi kuma-reactor enuzi ukuqinisekisa ukusetshenziswa okuphephile kwamandla enuzi.
Ngaphezu kwezindawo zokufaka isicelo ezingenhla,I-ASTM A335 P22Ipayipi lensimbi elenziwe nge-alloy lingenziwa ngokwezifiso ngokwezidingo zamakhasimende ukuze lihlangabezane nezidingo zokusetshenziswa ezimweni ezithile. Isibonelo, ngokulungisa amapharamitha afana nokujiya kodonga, ububanzi nobude bepayipi lensimbi, lingahlangabezana nezidingo zamaphrojekthi ahlukene. Ngesikhathi esifanayo, ipayipi lensimbi lingaphathwa futhi ngobuso ngokwezidingo zamakhasimende, njengokufutha i-anti-corrosion coating, i-galvanizing, njll., ukuthuthukisa ukumelana kwayo nokugqwala kanye nokuphila kwayo kwenkonzo.
Ipayipi lensimbi ye-ASTM A335 P22, njengezinto zezimboni ezisebenza kahle kakhulu, lidlala indima ebalulekile emikhakheni eminingi. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokwanda okuqhubekayo kwamasimu okusetshenziswa, sinesizathu sokukholelwa ukuthi ipayipi lensimbi ye-ASTM A335 P22 lizoqhubeka nokufaka isandla ekuthuthukisweni kwezimboni esikhathini esizayo.
