Ingabe uyazi ngamashubhu kabhayela angenamthungo i-20G ne-SA-210C (25MnG)?

Ingabe uyazi ngamashubhu kabhayela angenamthungo i-20G ne-SA-210C (25MnG)?

I-20G iyizinga lensimbi elifakwe ku-GB/T5310 (amabanga ahambisanayo angaphandle: i-st45.8 eJalimane, i-STB42 e-Japan, i-SA106B e-United States), futhi iyinsimbi esetshenziswa kakhulu kumapayipi ensimbi okubhayela. Ukwakheka kwayo kwamakhemikhali kanye nezakhiwo zemishini ngokuyisisekelo kuyafana nalezo zamapuleti angama-20. Le nsimbi inezinga lokushisa elithile legumbi namandla okushisa aphakathi nendawo, okuqukethwe kwekhabhoni ephansi, ipulasitiki enhle nokuqina, kanye nokusebenza okuhle okubandayo nokushisayo nokushisela. Isetshenziselwa ikakhulukazi ukukhiqiza okokufaka kubhayela ngomfutho ophezulu kanye nemingcele ephakeme, ama-superheaters nama-reheaters ingxenye enezinga lokushisa eliphansi, izivikeli zomnotho, nezindonga ezipholiswe ngamanzi; Isibonelo, amapayipi amancane obubanzi asetshenziswa njengokushisisa amapayipi angaphezulu anezinga lokushisa elinodonga elingu-≤ 500 ℃, kanye namapayipi odonga apholile ngamanzi kanye namapayipi e-economizer. Ngenxa ye-graphitization ebangelwa ukusebenza kwesikhathi eside kwe-carbon steel engaphezu kuka-450 ℃, kungcono ukukhawulela izinga lokushisa eliphakeme lesikhathi eside lamapayipi njengezindawo zokufudumeza libe ngaphansi kuka-450 ℃. Le nsimbi ingahlangabezana nezidingo zama-superheaters namapayipi omusi kuleli banga lokushisa ngokwamandla, futhi inokumelana okuhle kwe-oxidation, ipulasitiki enhle, ukuqina, ukusebenza kwe-welding nezinye izakhiwo ezibandayo nezishisayo zokucubungula, okwenza isetshenziswe kabanzi.

I-SA-210C (25MnG) iyizinga lensimbi elisezingeni le-ASME SA-210. Ipayipi elincane lensimbi eliwububanzi be-carbon manganese elisetshenziswa kumaboilers nama-superheaters, kanye nohlobo lwe-pearlescent yensimbi enamandla amakhulu. Inqubo yokukhiqiza yale nsimbi ilula, futhi ukusebenza kwayo okubandayo nokushisayo kokucubungula kuhle. Ukushintsha i-20G ngayo kunganciphisa ukushuba kwezindonga ezincane, kunciphise ukusetshenziswa kwezinto ezibonakalayo, futhi kuthuthukise isimo sokudlulisa ukushisa kwama-boilers.

Indawo esetshenziswayo nezinga lokushisa ngokuyisisekelo kuyafana ne-20G, ikakhulukazi esetshenziselwa izindonga ezipholiswe ngamanzi, okomnotho, ama-high-temperature aphansi kanye nezinye izingxenye ezinamazinga okushisa asebenzayo angaphansi kuka-500 ℃.

I-Shandong Kungang Metal Technology Co., Ltd. ikakhulukazi ikhiqiza imikhiqizo yamapayipi ensimbi. I-20G ne-SA-210C yizinto ezisetshenziswa kakhulu ezingenamthungo ezindaweni zokugcina izimpahla, futhi imininingwane ekhethekile ingakhiqizwa ngokuya ngezidingo zamakhasimende. Umkhiqizo wenziwe ngensimbi yekhwalithi ephezulu, futhi zonke izinkomba zomzimba nezamakhemikhali zihlangabezana nezindinganiso zikazwelonke. Umkhiqizo udumile kokubili ngaphakathi nangaphandle. Sibheke ngabomvu ukubonisana kwakho!
