I-ASTM A53 Gr.Bngomnye wemigangatho yemibhobho yentsimbi eyenziwe yi-American Society for Testing and Materials (ASTM). Oku kulandelayo yintshayelelo eneenkcukacha kwimibhobho yentsimbi engenamthungo ye-A53 Gr.B:
1. Isishwankathelo
Umbhobho wentsimbi engenamthungo we-ASTM A53 Gr.B. Phakathi kwemigangatho yemibhobho yentsimbi eyenziwe yi-American Society for Testing and Materials (ASTM), i-ASTM A53 yahlulwe yangamanqanaba amabini, u-A kunye no-B. I-ASTM imele iseti yemigangatho yaseMelika. Umgangatho ohambelanayo waseTshayina we-A53A yi-GB8163, eyenziwe ngentsimbi yeNombolo 10, kwaye umgangatho ohambelanayo waseTshayina we-A53B yi-GB8163, eyenziwe ngentsimbi yeNombolo 20. Isetyenziswa kakhulu kwiipayipi zenjongo eqhelekileyo.
2. Inkqubo yokuvelisa
I-ASTM A53 Gr.BIsebenzisa kakhulu iteknoloji yemibhobho engenamthungo kwinkqubo yokuvelisa. Iteknoloji yemibhobho engenamthungo ibhekisa kwinkqubo yokucubungula i-billet ibe yipayipi yentsimbi enobukhulu obufanayo bodonga kunye nomphezulu wangaphakathi nangaphandle ogudileyo ngeenkqubo ezifana nokugqobhoza i-billet, ukuqengqeleka, kunye nokwandiswa kobubanzi. Nangona umgangatho we-ASTM A53 uvumela ukusetyenziswa kweteknoloji yemibhobho edibeneyo ukwenza imibhobho yentsimbi, ekwenziweni kweI-ASTM A53 Gr.B, iteknoloji yombhobho engenamthungo yeyona ndlela iphambili yokuvelisa.
3. Iimpawu zeMveliso
Ubukhulu bodonga obuphezulu kunye nokuchaneka kobubanzi bangaphandle: Ubukhulu bodonga kunye nobubanzi bangaphandle bombhobho ongenamthungo we-ASTM A53 Gr.B buchanekile kakhulu kwaye bunokuhlangabezana neemfuno zezakhiwo ezahlukeneyo ezintsonkothileyo.
Ukumelana noxinzelelo oluqinileyo kunye nokumelana nokugqwala:I-ASTM A53 Gr.Bumbhobho ongenamthungo unokumelana noxinzelelo oluphezulu kunye nokugqwala, kwaye unokusebenza ngokuzinzileyo ixesha elide kwiindawo ezahlukeneyo ezinzima.
Ukusetyenziswa ngokubanzi: Umbhobho ongenamthungo we-ASTM A53 Gr.B ufanelekile kwiinkqubo zemibhobho zokuhambisa igesi, ulwelo kunye nezinye izinto ezimanzi, kubandakanya ukusetyenziswa kwemizi-mveliso, unikezelo lwamanzi kunye neenkqubo zokufudumeza.
4. Uluhlu oluqhelekileyo
Umgangatho we-ASTM A53 GRB usebenza kwimibhobho yentsimbi yekhabhoni ethe tye (eweld) kunye nentsimbi yekhabhoni engenamthungo, egubungela uluhlu olubanzi lweedayamitha zangaphandle, ubukhulu bodonga kunye neendlela zokucubungula. Ngokweemfuno ezahlukeneyo zokusetyenziswa, imibhobho esemgangathweni ye-ASTM A53 GRB ingagqunywa nge-galvanized, ibekwe ngemibhobho, igqunywe nge-coating, njl.njl. ukuphucula ukumelana kwayo nokugqwala kunye nobomi benkonzo.
