MayelanaUkufakwa kwepayipi le-ASTM A234 WPB
I-ASTM A234 iwukucaciswa Okujwayelekile kokufakwa kwamapayipi ensimbi kufaka ikhabhoni kanye nezinto zensimbi yealloy kumasevisi okushisa aphakathi nendawo naphezulu.Ihlanganisa ukufakwa kwensimbi kwezinhlobo ezingenamthungo nezishiselwe.Ukufakwa kwepayipi lensimbi kusetshenziswa kumapayipi okucindezela kanye nokwakhiwa kwemikhumbi yokucindezela.Lezi zinto zokufakwayo zihlanganisa insimbi ebulewe, ama-forging, imigoqo, amapuleti, imikhiqizo yamapayipi engenamthungo noma i-HFW (i-fusion welded), ene-filler metal.
Yini i-WPB?
W = WELDABLE / eyenziwe
P = OKUPHATHANA NENOMBOLO YE-P YEMALI YEALLOY
B = BHEKISELA KUMVUZO OBUNCINANE WEZIMALI
Ayatholakala ekubuyekezweni kwakamuva kwe-ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, ne-MSS-SP-97.Ibuye isetshenziswe kabanzi ekufakweni kwamapayipi okucindezelayo nasekukhiqizeni imikhumbi yokucindezela ukuze isebenze emazingeni okushisa aphakathi nendawo naphezulu.Amabanga yi-ASTM A234 WPB, WPC, WP5, WP9, WP91, WP11, WP12 kanye neWP22.
Imininingwane:
Amazinga: ANSI /ASME B16.9, B16.28, MSS-SP-43.

Umehluko Phakathi kwe-A105 ne-A234
I-ASTM A234 WPB Pipe Fittings yenziwe ngensimbi yekhabhoni eyenziwe yaqina kakhulu futhi ingasetshenziswa ezidingweni zamandla aphezulu.I-ASTM A234 WPB iphathwa ngokushisa bese ivunyelwa ukuthi iphole ngokushesha.
I-Carbon Steel Forged Fittings izifakelo zamapayipi ezenziwe nge-A105 Material.Lezi zikhiqizwa ngaphansi kwezimo ezifakwe emanzini, ezijwayelekile, ezijwayelekile nezipholile noma ezicishiwe nezipholile.
