Dhayamita Range
ASTM A179 yemachubhu ane dhayamita yekunze iri pakati pe3.2 -76.2 mm [NPS 1/8 - 3 in.].
Kurapa Kupisa
Kupisa kwacho kwagadziriswa pa1200℉ [650℃] kana kupfuura mushure mekudhonza mvura inotonhora kwekupedzisira.
Chitarisiko
Pombi yesimbi yapera haifanirwe kunge iine chikero. Kuoxidation kudiki hakuonekwi sechikero.
