Ipayipi lensimbi elingenamthungo le-alloy liwuhlobo lwepayipi lensimbi elingenamthungo, futhi ukusebenza kwalo kuphakeme kakhulu kunokwepayipi lensimbi elingenamthungo elivamile, ngoba leli payipi lensimbi liqukethe i-Cr eyengeziwe, futhi ukumelana kwalo nokushisa okuphezulu, ukumelana nokushisa okuphansi kanye nokusebenza kokumelana nokugqwala kungcono kunezinye ipayipi lensimbi elingenamthungo. Ayinakuqhathaniswa, ngakho-ke amashubhu e-alloy asetshenziswa kabanzi ku-petroleum, amakhemikhali, amandla kagesi, i-boiler nakwezinye izimboni. Ipayipi lensimbi elingenamthungo le-alloy (i-Seamless Steel Tube) linengxenye engenalutho, umugqa wensimbi omude ongenamajoyinti ayizungezile. Ipayipi lensimbi linengxenye engenalutho futhi lisetshenziswa kabanzi njengepayipi lokuthutha uketshezi, njengepayipi lokuthutha uwoyela, igesi yemvelo, igesi, amanzi kanye nezinto ezithile eziqinile. Uma liqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi elingenamthungo le-alloy linamandla afanayo okugoba nokujika kanye nesisindo esilula. Liyinsimbi yengxenye engabizi futhi lisetshenziswa kabanzi ekwenziweni kwezingxenye zesakhiwo nezingxenye zemishini, njengokuthuthwa kwamafutha. Ukwenza izingxenye zendandatho ngepayipi lensimbi elingenamthungo le-alloy kungathuthukisa izinga lokusetshenziswa kwezinto, kwenziwe lula inqubo yokukhiqiza, konge izinto kanye nesikhathi sokucubungula, njengendandatho yokuthwala egoqayo, amasethi e-jack, njll., asetshenziswe kabanzi ekukhiqizeni amapayipi ensimbi. Ipayipi lensimbi engenamthungo ye-alloy nayo iyinto ebalulekile yezikhali ezahlukahlukene ezivamile, futhi i-barrel, i-barrel, njll. kumele yenziwe ngepayipi lensimbi. Ngaphezu kwalokho, lapho ingxenye yendandatho icindezelwa yi-radial yangaphakathi noma yangaphandle, amandla afanayo. Ngakho-ke, amapayipi amaningi ensimbi engenamthungo ye-alloy ayipayipi eyindilinga.
Ukuhlukaniswa:
Ipayipi lensimbi elingenamthungo lesakhiwo: isetshenziswa kakhulu kwisakhiwo esijwayelekile kanye nesakhiwo semishini. Izinto zayo ezimele (uphawu): insimbi yekhabhoni engu-20, insimbi engu-45; insimbi ye-alloy engu-Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, njll.
Amapayipi ensimbi angenamthungo okuhambisa uketshezi: isetshenziswa kakhulu ekuthuthweni kwamapayipi oketshezi kwezobunjiniyela kanye nemishini emikhulu. Izinto ezimele (ibanga) zingama-20, Q345, njll.
Amapayipi ensimbi angenamthungo ama-boilers anomfutho ophansi nophakathi: isetshenziswa kakhulu kumapayipi okuhambisa uketshezi oluphansi noluphakathi kuma-boiler ezimboni kanye nama-boiler asekhaya. Izinto ezimele ziyinsimbi engu-10, 20.
Amapayipi ensimbi angenamthungo ama-boilers anomfutho ophezulu: isetshenziswa kakhulu kuma-header kanye namapayipi okuthutha uketshezi oluhamba ngokushisa okuphezulu kanye nokucindezela okuphezulu kuma-boiler ezitshalweni zamandla kanye nasezitshalweni zamandla enuzi. Izinto ezimele ziyi-20G, 12Cr1MoVG, 15CrMoG, njll.
Amapayipi ensimbi angenamthungo emishini yomanyolo enomfutho ophezulu: isetshenziswa kakhulu kumapayipi oketshezi ashisa kakhulu futhi anomfutho ophezulu emishinini kamanyolo. Izinto ezimele ziyi-20, 16Mn, 12CrMo, 12Cr2Mo, njll.
Amapayipi ensimbi angenamthungo okuqhekeka uwoyela: esetshenziswa kakhulu kuma-boiler, kuma-heat exchanger kanye namapayipi awo oketshezi lokudlulisa kuma-oil smelters. Izinto ezimele wona ziyi-20, 12CrMo, 1Cr5Mo, 1Cr19Ni11Nb, njll.
Amapayipi ensimbi angenamthungo amasilinda egesi: asetshenziswa kakhulu ekwenzeni amasilinda ahlukahlukene egesi kanye ne-hydraulic. Izinto ezimele wona yi-37Mn, 34Mn2V, 35CrMo njalo njalo.
Amapayipi ensimbi angenamthungo ashiswayo ezinto zokusekela amanzi: asetshenziswa kakhulu ekwenzeni izisekelo zamanzi, amasilinda namakholomu ezimayini zamalahle, kanye namanye amasilinda namakholomu e-hydraulic. Izinto ezimele wona ziyi-20, 45, 27SiMn, njll.
Ipayipi lensimbi elingenamthungo elidonswa ngokubandayo noma eligoqwa ngokubandayo: lisetshenziselwa kakhulu isakhiwo semishini, imishini yokucindezela ikhabhoni, edinga ukunemba okuphezulu kanye nokuqeda okuhle kobuso. Izinto ezimele yona yinsimbi engu-20, 45, njll.
