I-ASTM A53 Gr.Byenye yemigangatho yentsimbi yombhobho eyenziwe yi-American Society for Testing and Materials (ASTM). Oku kulandelayo yintshayelelo eneenkcukacha zombhobho wentsimbi ongenamthungo we-A53 Gr.B:
1. Isishwankathelo
I-ASTM A53 Gr.B umbhobho wentsimbi ongenamthungo. Phakathi kwemigangatho yepayipi yensimbi eyenziwe yi-American Society for Testing and Materials (ASTM), i-ASTM A53 ihlukaniswe ngamanqanaba amabini, i-A kunye ne-B. ASTM imele imilinganiselo yaseMelika. Umgangatho ohambelanayo waseTshayina we-A53A yi-GB8163, eyenziwe nge-No. Isetyenziselwa ikakhulu kwimibhobho yenjongo ngokubanzi.
2. Inkqubo yokuvelisa
I-ASTM A53 Gr.Bikakhulu isebenzisa iteknoloji umbhobho ingenamthungo kwinkqubo yokuvelisa. Ubuchwephesha bombhobho obungenamthungo bubhekisa kwinkqubo yokusetyenzwa kwebillet ibe ngumbhobho wentsimbi enobunzima obufanayo bodonga kunye nemigangatho egudileyo yangaphakathi nangaphandle ngeenkqubo ezinje ngokugqobhoza kwebillet, ukuqengqeleka, kunye nokwandiswa kwedayamitha. Nangona umgangatho we-ASTM A53 uvumela ukusetyenziswa kobuchwepheshe bemibhobho edityanisiweyo ukwenza imibhobho yentsimbi, ekwenzeniI-ASTM A53 Gr.B, iteknoloji yombhobho engenamthungo yeyona ndlela yokuvelisa.
3. Iimpawu zeMveliso
Ubukhulu bodonga oluphezulu kunye nokuchaneka kwedayimitha yangaphandle: Ubukhulu bodonga kunye nobubanzi bangaphandle be-ASTM A53 Gr.B umbhobho ongenamthungo unokuchaneka okuphezulu kwaye unokuhlangabezana neemfuno zezakhiwo ezahlukahlukeneyo.
Ukumelana noxinzelelo olunamandla kunye nokumelana nomhlwa:I-ASTM A53 Gr.Bumbhobho ongenamthungo unokumelana noxinzelelo oluphezulu kunye nokumelana nomhlwa, kwaye unokusebenza ngokuzinzileyo ixesha elide kwiindawo ezahlukeneyo ezinzima.
Ukusetyenziswa ngokubanzi: umbhobho we-ASTM A53 Gr.B ongenamthungo ufanelekile kwiinkqubo zemibhobho yokuhambisa igesi, ulwelo kunye nolunye ulwelo, kubandakanywa ukusetyenziswa kwemizi-mveliso, ukubonelela ngamanzi kunye neenkqubo zokufudumeza.
4. Uluhlu olusemgangathweni
Umgangatho we-ASTM A53 GRB usebenza kumthungo othe tye (weld) kunye nemibhobho yentsimbi yekhabhoni engenamthungo, egubungela iindidi zangaphandle, ubukhulu bodonga kunye neendlela zokucubungula. Ngokweemfuno ezahlukeneyo zesicelo, i-ASTM A53 GRB imibhobho esemgangathweni inokuphinda ifakwe i-galvanized, ifakwe umgca, ifakwe, njl.
