(1)Iingqiniba zokuwelda ngeempunduinokohlulwa ibe yingqiniba yokuwelda iradius butt kunye nengqiniba yokuwelda yeradius butt emfutshane ngokweradiyasi yokugoba.Iradiyasi yegophe yengqiniba yeradius butt welding ilingana namaxesha ayi-1.5 edayamitha yangaphandle yombhobho, oko kukuthi, R=1.5D.Iradiyasi yokugoba kwengqiniba yerediyasi kodwa ilingana nedayamitha yangaphandle yombhobho, oko kukuthi, R=1D.Kwifomula, i-D yi-diameter ye-butt welding elbow, kwaye i-R yiradiyasi yokugoba.Ukuba akukho nkcazo ekhethekileyo, i-elbow ye-1.5D isetyenziswa ngokubanzi.
(2) Ngokwenqanaba loxinzelelo, kukho malunga neentlobo ezilishumi elinesixhenxe, ezifanayo nemigangatho yombhobho waseMelika, kuquka: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;I-Sch80 , i-Sch100, i-Sch120, i-Sch140, i-Sch160, i-XXS, eyona nto isetyenziswa kakhulu yi-STD kunye ne-XS.
(3) Ngokwe-engile yengqiniba, kukho i-45-degree butt-welding elbows, i-90-degree butt-welding elbows, i-180-degree-butt-welding elbows kunye nezinye ii-angles ezineengile ezahlukeneyo.
(4) Izinto eziphathekayo: i-carbon steel, i-alloy steel kunye nensimbi engenasici.
