Dhererka dhexroorka
ASTM A179 ee tuubooyinka leh dhexroorka ka baxsan 3.2 -76.2 mm [NPS 1/8 - 3 in.].
Daawaynta kulaylka
Kulaylka lagu daweeyay 1200℉ [650℃] ama ka sareeya ka dib marinka nuugista qabow ee u dambaysay.
Muuqashada
Dhuumaha birta ah ee dhammaatay waa in aanay yeelan miisaan.oksaydheynta yar looma tixgalinayo miisaan.

Calaamadeynta ASTM A179
ASTM A179waa in si cad loogu calaamadiyaa magaca soo saaraha ama magaca sumadda, lambarka qeexida, darajada, iyo magaca iibsadaha iyo lambarka dalbashada.
Baahida calaamadaynta kuma jirto taariikhda sanadka ee tilmaantan.
Tuubooyinka ka yar 31.8 mm [11/4dhexroorka iyo tuubooyinka dhererkoodu ka hooseeyo 1 m [3 ft], macluumaadka loo baahan yahay waxaa lagu calaamadayn karaa sumad si ammaan ah ugu dheggan xirmada ama sanduuqa tuubooyinka lagu soo raro.
