Iityhubhu zentsimbi ezingenamthungo kwiibhoyili zoxinzelelo oluphezulu zibandakanyaGB/5310-2007umgangatho,ASME SA-106/SA-106M-2015,I-ASTMA210(A210M)-2012, iityhubhu zentsimbi ephakathi kwekhabhoni engenamthungo yeebhoyila kunye nezifudumezi ezinkulu,ASME AS – 213 / SA – 213 M, I-ASTM A335 / A335M - 2018.

GB/T5310-2017isetyenziselwa ikakhulu ukwenza uxinzelelo oluphezulu kunye nemibhobho yebhoyila yoxinzelelo oluphezulu kunye nezinye intsimbi ekumgangatho ophezulu wekhabhoni, ingxubevange yentsimbi kunye nombhobho wentsimbi okwaziyo ukumelana nobushushu. Umgangatho ophezulu we-carbon structural steel steel 20g, 20mg, 25mg. Ingxubevange yentsimbi yentsimbi 15MOG, 20MOG, 12CrMOg, 15CrMOg, 12Cr2MOG, 12CrMOVG, 12Cr3Movsitib, njl.

Umhlwa intsimbi ukumelana nobushushu edla ngokusetyenziswa 1Cr18Ni9, 1Cr18NillNb

Izinto eziphambili ezihambelanayoGB/T5310umgangatho: 20G, 20MnG, 25MnG, 16Mn, 15Mog.20MOG, 15CrMo, 15CrMoG, 12CrlMoV, 12Cr1MoVG, Cr5Mo, 10CrMo910 iimfuno eziphambili zovavanyo: ukongeza ekuqinisekiseni ukubunjwa kweekhemikhali kunye neempawu zoxinzelelo lwamanzi, ukwenza iipropathi zovavanyo lomatshini, ukwenza uvavanyo. Ukongeza, i-microstructure, ubungakanani beengqolowa kunye ne-decarburization layer yeetyhubhu zetsimbi ezigqityiweyo nazo ziyafuneka. Ubume bokuhanjiswa: Unyango lobushushu

Xa imibhobho yentsimbi engenamthungo ithunyelwa kumazwe abathengi, kunokubakho okwahlukileyoiindlela zokupakishangokweemfuno ezahlukeneyo zomthengi. Kutshanje, kwiimpahla esizithumele eVietnam, umthengi ukhethe ukuthuthwa kwe-casing ukunciphisa umthamo weempahla kunye nokugcina iindleko zokupakisha. Sikwanayo PVC ukupakisha, baling ukupakisha, intsimbi isakhelo ukupakisha, casing ukupakisha njalo njalo. Ungajonga iwebhusayithi yethu ngezinye iindlela zokupakisha. I-alloy steel tube, ityhubhu yentsimbi engenamthungoSA106 GR.B, ityhubhu yeoliK55,L80, njl., inokwamkela oku ngasentlaindlela yokupakisha.
