Amashubhu ensimbi angenamthungo ama-boilers anengcindezi ephezulu ahlanganisaGB/5310-2007ejwayelekile,ASME SA-106/SA-106M-2015,I-ASTMA210(A210M)-2012, amashubhu ensimbi angenamthungo e-carbon steel ama-boilers nama-superheaters,ASME AS – 213 / SA – 213 M, I-ASTM A335 / A335M – 2018.

I-GB/T5310-2017isetshenziswa kakhulu ukwenza umfutho ophakeme kanye nangaphezulu kwengcindezi yamapayipi ebhayela yesitimu kanye nezinye insimbi yekhwalithi ephezulu ye-carbon structural, i-alloy structural steel kanye nensimbi engagqwali ukumelana nokushisa kwepayipi lensimbi engenamthungo. Ikhwalithi ephezulu ye-carbon structural steel steel 20g, 20mg, 25mg. I-alloy structural steel steel 15MOG, 20MOG, 12CrMOg, 15CrMOg, 12Cr2MOG, 12CrMOVG, 12Cr3Movsitib, njll.

Insimbi engamelana nokugqwala evame ukusetshenziswa 1Cr18Ni9, 1Cr18NillNb

Izinto eziyinhloko ezihambisana neI-GB/T5310okujwayelekile: 20G,20MnG,25MnG,16Mn, 15Mog.20MOG, 15CrMo,15CrMoG,12CrlMoV,12Cr1MoVG,Cr5Mo, 10CrMo910 izidingo zokuhlola eziphambili: ngaphezu kokuqinisekisa ukwakheka kwamakhemikhali kanye nezakhiwo zokuhlola zemishini, ukwenza test. Ngaphezu kwalokho, i-microstructure, usayizi wokusanhlamvu kanye nongqimba lwe-decarburization lwamashubhu ensimbi aphelile nawo ayadingeka. Isimo sokulethwa: Ukwelashwa kokushisa

Lapho amapayipi ensimbi engenamthungo ethunyelwa emazweni amakhasimende, kungaba khona okuhlukileizindlela zokupakishangokwezidingo ezahlukene zekhasimende. Muva nje, ezimpahleni esizithumele eVietnam, ikhasimende likhethe ukuthuthwa kwe-casing ukunciphisa umthamo wezimpahla futhi lilondoloze izindleko zokupakisha. Siphinde sibe nokupakisha kwe-PVC, ukupakisha ukupakisha, ukupakisha uhlaka lwensimbi, ukupakisha kwe-casing nokunye. Ungahlola iwebhusayithi yethu ukuze uthole ezinye izindlela zokupakisha. I-alloy steel tube, ishubhu yensimbi engenamthungoI-SA106 GR.B, ithubhu lamafuthaK55,L80, njll., ingasebenzisa lokhu okungenhlaindlela yokupakisha.
