Diameter Range
ASTM A179 yamachubu okhala ndi ma diameter akunja pakati pa 3.2 -76.2 mm [NPS 1/8 - 3 in.].
Kutentha Chithandizo
Kutentha kumatenthedwa pa 1200 ℉ [650 ℃] kapena kupitilira apo mutatha kuzizira komaliza.
Maonekedwe
Chitoliro chachitsulo chomalizidwa chisakhale ndi sikelo.Kuchuluka kwa okosijeni sikutengedwa ngati sikelo.
