I-ASTM A53 iBanga B ngumbhobho wensimbi odibeneyo okanye ongenamthungo kunye namandla amancinci okuvelisa i-240 MPa kunye namandla obunzima be-415 MPa yokuthutha umbane ophantsi.
I-ASTM A53 Uhlobo lweBanga B lwemibhobho
Uhlobo F- I-Furnace-butt-welded, i-welded eqhubekayo
Yinkqubo apho iipleyiti zetsimbi zifudumeza kwisithando somlilo esiphezulu kunye ne-welded usebenzisa i-welding consumables.Kwinkqubo ye-welding, ipleyiti yensimbi ifudumala kwiqondo lokushisa elaneleyo kwaye emva koko ifakwe kwisithando somlilo ngokusebenzisa izinto ezisetyenziselwa ukudibanisa ukwenza i-weld seam.I-welding eqhubekayo ithetha ukuba ipleyiti yensimbi iqhutywe ngokuqhubekayo kwisithando somlilo, evumela ukuveliswa kobude obude bombhobho.
Uhlobo E- Electric-resistance-welded
Le yinkqubo ye-welding apho imida yeeplati zetsimbi ifudunyezwa kwaye icinezelwe kunye ukuze yenze i-weld ngokufaka umbane wombane kuzo zombini iziphelo zombhobho usebenzisa ukufudumeza ukuxhathisa kunye noxinzelelo.Endaweni yokusebenzisa i-welding consumables etyhidiweyo, ukufudumeza ukufudumeza kutshisa imiphetho yepleyiti yentsimbi kwiqondo lobushushu elaneleyo kwaye ifaka uxinzelelo ukwenza i-weld kwimida yeplate yentsimbi.
Uhlobo S - Ingenamthungo
Umbhobho wentsimbi ongenamthungo wenziwa ngokuthe ngqo kumbhobho ngaphandle kwemithungo ngokuqengqeleka, ukugqobhoza, okanye ukukhupha.
Iimpahla ezingekasilwa
Isithando somlilo esivulekileyo, isithando somlilo sombane, okanye ioksijini yealkaline.
Inkqubo enye okanye ngaphezulu ingasetyenziswa.
Unyango lobushushu
Welds inUhlobo E kwiBanga B or Uhlobo F iBanga Bumbhobho uya kunyangwa ubushushu emva ukuwelda ukuya ubuncinane 1000 °F [540°C] ukuze kungabikho martensite enganyangekiyo ekhoyo, okanye ngenye indlela iphathwe ukuze kungabikho martensite untempered ekhoyo.
