Makulidwe a m'mimba mwake
ASTM A179 ya machubu okhala ndi mainchesi akunja pakati pa 3.2 -76.2 mm [NPS 1/8 - 3 in.].
Kutentha Chithandizo
Kutentha kumakonzedwa pa kutentha kwa 1200℉ [650℃] kapena kupitirira apo mukamaliza kuyamwa madzi ozizira.
Maonekedwe
Chitoliro chachitsulo chomalizidwa sichiyenera kukhala ndi sikelo. Kusungunuka pang'ono sikuonedwa ngati sikelo.
