13CrMo4-5 ND Ipayipi lensimbi engenamthungo
09CrCuSb(ND) ithubhu yensimbi engenamthungo yokumelana ne-sulfuric acid, izinga lokushisa eliphansi lamazolo kanye nokugqwala
Insimbi ye-ND iwuhlobo olusha lwensimbi yesakhiwo se-alloy ephansi, uma iqhathaniswa nezinye insimbi, njengensimbi enekhabhoni ephansi, i-Corten, i-CRIA, insimbi ye-ND inenzuzo yokumelana nokugqwala okuhle kakhulu kanye nempahla yokukhanda.Imiphumela yokuhlolwa ibonise ukuthi ukumelana nokugqwala kwensimbi ye-ND kusisombululo esinamanzi njenge-sulfuric acid, i-hydrochloric acid ne-sodium chloride kuphakeme kune-carbon steel.Isici esivelele kakhulu yikhono lokumelana ne-sulfuric acid dew pointcorrosion resistance;Impahla engumshini iphakeme futhi izinzile kune-carbon steel ukusuka ekamelweni lokushisa kuya ku-500 C, futhi ukusebenza kokushisela kuhle.Insimbi ye-ND ihlale isetshenziselwa ukukhiqiza i-economizer, isishintshi sokushisa, i-air pre-heater, kusukela ngo-1990, i-ND steel ibisetshenziswa kabanzi embonini yokuphehla nogesi.

Ishubhu yensimbi engenamthungo ye-Heat exchanger / Boiler pipe
Isethulo somkhiqizo:
Ukwelashwa Kokushisa-Iyindlela esebenzisa ukushisisa nokupholisa ukuze kushintshwe izici ezibonakalayo zamapayipi obhayela anomfutho ophezulu.Ukwelashwa kokushisa kungathuthukisa i-microstructure ye-tube boiler ye-high-pressure, ukuze kuzuzwe izidingo zomzimba ezidingekayo.Ukuqina, ubulukhuni, nokumelana nokugqokwa yizici ezimbalwa ezitholakala ngokwelashwa kokushisa.Ukuze uthole lezi zici, sebenzisa i-quenching & lt ekwelapheni ukushisa;ebizwa nangokuthi quenching & gt;, tempering, annealing & lt;ukuncibilika & gt;kanye nokuqina kwendawo, njll.

I-P235GH ST35.8 SA192 Ipayipi Lensimbi Engenamthungo / Ishubhu le-Boiler
Isethulo somkhiqizo:
Ipayipi le-boiler luhlobo lwepayipi elingenamthungo.Indlela yokukhiqiza iyafana nepayipi elingenamthungo, kodwa kunezidingo eziqinile zohlobo lwensimbi olusetshenziselwa ukukhiqiza ipayipi lensimbi.Ngokusho kwezinga lokushisa lokusetshenziswa, ihlukaniswe ipayipi elivamile le-boiler kanye ne-high pressure boiler pipe.

T11 T12 T22 T91 T92 Ingxubevange Steel Ipayipi Seamless
Isethulo somkhiqizo:
Ipayipi lensimbi engenamthungo iwuhlobo lwepayipi lensimbi elingenamthungo, ukusebenza kwalo kuphakeme kakhulu kunepayipi elivamile lensimbi elingenamthungo, ngoba lolu hlobo lwepayipi lensimbi luqukethe ukuqhathanisa kwe-Cr.
Eziningi, ukumelana kwayo nokushisa okuphakeme, ukumelana nokushisa okuphansi, ukusebenza kokumelana nokugqwala akufani nezinye ipayipi lensimbi engenamthungo, ngakho-ke ipayipi lengxubevange kuwoyela, imboni yamakhemikhali, amandla kagesi, ubhayela nezinye izimboni zisetshenziswa kabanzi.
Ipayipi lensimbi engenamthungo liqukethe izakhi ezifana ne-silicon, i-manganese, i-chromium, i-nickel, i-molybdenum, i-tungsten, i-vanadium, i-titanium, i-niobium, i-zirconium, i-cobalt, i-aluminium, ithusi, i-boron, umhlaba ongavamile njalonjalo.

I-A106B A210A1 A210C / Ipayipi Lensimbi Le-Carbon Engenamthungo
Isethulo somkhiqizo:
Ipayipi le-boiler luhlobo lwepayipi elingenamthungo.Indlela yokukhiqiza iyafana nepayipi elingenamthungo, kodwa kunezidingo eziqinile zohlobo lwensimbi olusetshenziselwa ukukhiqiza ipayipi lensimbi.
Izakhiwo zemishini yepayipi ye-boiler iyinkomba ebalulekile yokuqinisekisa ukusebenza kokugcina kwenkonzo (izakhiwo zemishini) yensimbi, okuncike ekubunjweni kwamakhemikhali kanye nesistimu yokushisa ukushisa kwensimbi.Esilinganisweni sepayipi lensimbi, ngokwezidingo ezihlukene zokusetshenziswa, ukusebenza okuqinile (amandla okuqina, amandla okukhiqiza noma iphuzu lesivuno, ubude), kanye nezinkomba zokuqina nokuqina, kanye nokusebenza kwezinga lokushisa eliphezulu neliphansi elidingwa abasebenzisi.
Enqubweni yokukhiqiza ipayipi yensimbi engenamthungo ye-boiler, ukwelashwa kokushisa kuyinqubo eyinhloko.Ukwelashwa kokushisa kunomthelela obalulekile kwikhwalithi yangaphakathi kanye nekhwalithi yendawo yepayipi yensimbi engenamthungo, ebaluleke kakhulu ekukhiqizeni ipayipi yensimbi engenamthungo.
Inkampani yethu yamukela ukwelashwa kokushisa okungeyona i-oxidation, ukukhiqizwa kwamapayipi ensimbi anenhlangano ezinzile ye-metallographic kanye nekhwalithi enhle yangaphakathi nangaphandle, isebenzisa ukutholwa kwe-eddy yamanje kanye ne-ultrasonic othomathikhi, ipayipi lensimbi ngalinye ukuze kutholwe iphutha lamanje le-eddy kanye nokutholwa kwamaphutha e-ultrasonic.Ngesilinganiso sobukhulu be-ultrasonic kanye nemisebenzi yokuthola amaphutha e-oblique, ingakwazi ukubona kahle amaphutha agqinsile epayipini lensimbi.
