I-ASTM A53 Gr.Bingenye yezindinganiso zamapayipi ensimbi ezakhiwe yi-American Society for Testing and Materials (ASTM). Okulandelayo yisingeniso esiningiliziwe sepayipi lensimbi elingenamthungo le-A53 Gr.B:
1. Ukubuka konke
Ipayipi lensimbi elingenamthungo le-ASTM A53 Gr.B. Phakathi kwezindinganiso zamapayipi ensimbi ezakhiwe yi-American Society for Testing and Materials (ASTM), i-ASTM A53 ihlukaniswe ngamaleveli amabili, u-A no-B. I-ASTM imele isethi yezindinganiso zaseMelika. Izinga elihambisanayo lesiShayina le-A53A yi-GB8163, elenziwe ngensimbi enguNombolo 10, kanti izinga elihambisanayo lesiShayina le-A53B yi-GB8163, elenziwe ngensimbi enguNombolo 20. Isetshenziswa kakhulu kumapayipi enhloso ejwayelekile.
2. Inqubo yokukhiqiza
I-ASTM A53 Gr.Bikakhulukazi isebenzisa ubuchwepheshe bamapayipi angenamthungo enqubweni yokukhiqiza. Ubuchwepheshe bamapayipi angenamthungo bubhekisela enqubweni yokucubungula i-billet ibe yipayipi lensimbi elinobukhulu obufanayo bodonga kanye nezindawo zangaphakathi nangaphandle ezibushelelezi ngezinqubo ezifana nokubhoboza i-billet, ukugoqa, kanye nokwandiswa kobubanzi. Nakuba indinganiso ye-ASTM A53 ivumela ukusetshenziswa kobuchwepheshe bamapayipi ahlanganisiwe ukukhiqiza amapayipi ensimbi, ekwenziweni kweI-ASTM A53 Gr.B, ubuchwepheshe bamapayipi angenamthungo buyindlela eyinhloko yokukhiqiza.
3. Izici Zomkhiqizo
Ubukhulu bodonga obuphezulu kanye nokunemba kobubanzi bangaphandle: Ubukhulu bodonga kanye nobubanzi bangaphandle bepayipi elingenamthungo le-ASTM A53 Gr.B linokunemba okuphezulu futhi lingahlangabezana nezidingo zezakhiwo ezahlukahlukene eziyinkimbinkimbi.
Ukumelana nokucindezela okunamandla kanye nokumelana nokugqwala:I-ASTM A53 Gr.Bipayipi elingenamthungo linokumelana nokucindezela okuphezulu kanye nokumelana nokugqwala, futhi lingasebenza kahle isikhathi eside ezindaweni ezahlukahlukene ezinzima.
Ukusetshenziswa okubanzi: Ipayipi elingenamthungo le-ASTM A53 Gr.B lifanele izinhlelo zamapayipi zokuhambisa igesi, uketshezi kanye nezinye izinto eziwuketshezi, okuhlanganisa ukusetshenziswa kwezimboni, ukuphakelwa kwamanzi kanye nezinhlelo zokushisa.
4. Ububanzi obujwayelekile
Izinga elijwayelekile le-ASTM A53 GRB lisebenza kumapayipi ensimbi yekhabhoni aqondile (weld) kanye nangenamthungo, amboza ububanzi obuhlukahlukene bangaphandle, ubukhulu bodonga kanye nezindlela zokucubungula. Ngokwezidingo ezahlukene zokusetshenziswa, amapayipi ajwayelekile e-ASTM A53 GRB nawo angagqunywa nge-galvanized, afakwe umugqa, ambozwe, njll. ukuze kuthuthukiswe ukumelana kwawo nokugqwala kanye nokuphila kwesikhathi senkonzo.
Isikhathi sokuthunyelwe: Disemba 30-2024
