Ipayipi lensimbi ye-alloy lisetshenziswa kakhulu embonini yamandla, amandla enuzi, kubhayela onengcindezi ephezulu, izinga lokushisa eliphezulu le-superheater kanye ne-reheater kanye nokunye ukucindezela okuphezulu kanye nepayipi lokushisa eliphezulu kanye nemishini, lenziwe ngensimbi yekhwalithi ephezulu ye-carbon steel, i-alloy structure kanye ne-stainless heat-resistant. impahla yensimbi, ngokugoqa okushisayo (ukukhipha, ukunwetshwa) noma ukugoqa okubandayo (ukudonsa).

Inzuzo enkulu yepayipi le-Alloy Steel ukuthi lingagaywa kabusha ngo-100%, okuhambisana nesu likazwelonke lokuvikela imvelo, ukonga amandla kanye nokonga izinsiza. Umgomo kazwelonke ukhuthaza ukunwetshwa kwenkundla yokusetshenziswa kwepayipi le-alloy elinengcindezi ephezulu.Okwamanje, ukusetshenziswa kwamashubhu engxubevange e-China kubala ingxenye kuphela yengqikithi yensimbi esetshenziswa emazweni athuthukile. Ukunwetshwa kwenkundla yokusetshenziswa kweshubhu lengxubevange kunikeza indawo ebanzi yokuthuthukiswa kwemboni.Ngokocwaningo lweqembu lochwepheshe begatsha le-alloy Pipe Branch of China Special Steel Association, isidingo sepayipi lengxube ye-high pressure e-China sizokhuphuka ngo-10. -12% njalo ngonyaka esikhathini esizayo.Ipayipi lengxubevange yipayipi lensimbi ngokuya ngokukhiqizwa kwezinto (okungukuthi, impahla) okumele kuchazwe, njengoba igama lisho ipayipi lengxubevange;Futhi ipayipi elingenamthungo liyipayipi lensimbi ngokwenqubo yokukhiqiza (elingenamthungo. ) ukuchaza, elihlukaniswa nepayipi elingenamthungo ipayipi lomthungo, okuhlanganisa ipayipi lokushisela lomthungo eliqondile kanye nepayipi elivunguzayo.

Izinto ze-alloy tube cishe kanjena:
