Kala duwanaanshaha dhexroorka
ASTM A179 ee tuubooyinka leh dhexroorka dibadda ee u dhexeeya 3.2 -76.2 mm [NPS 1/8 - 3 inji.].
Daaweynta Kulaylka
Kuleylka lagu daweeyay 1200 ℉ [650 ℃] ama ka sareeya ka dib marinka nuugista qabow ee ugu dambeeya.
Muuqaalka
Tuubada birta ah ee la dhammeeyay waa inaysan lahayn miisaan. Oksaydh yar looma tixgeliyo miisaan.
Dulqaadka Cabbirka

Imtixaanka Iftiiminta
Habka Tijaabada: ASTM A450 Qaybta 21aad.
Tijaabada Balaaran: Tijaabada Balaarinta waa tijaabo loo isticmaalo in lagu qiimeeyo isbeddelka balaastikada iyo iska caabbinta dildilaaca ee walxaha birta ah, gaar ahaan tuubooyinka marka la mariyo hababka balaarinta. Tijaabadan waxaa badanaa loo isticmaalaa in lagu qiimeeyo tayada iyo ku habboonaanta tuubooyinka, gaar ahaan marka loo baahdo alxanka, balaarinta ama noocyada kale ee wax lagu farsameeyo.
Tijaabada Flange-ka
Habka Tijaabada: ASTM A450 Qaybta 22. Beddelka Tijaabada Flare.
Su'aalo La Ballaariyay: Caadi ahaan waxaa loola jeedaa tijaabo loo isticmaalo in lagu qiimeeyo isbeddelka balaastikada iyo iska caabbinta dildilaaca ee birta xaashida ah, tuubooyinka, ama agabyada kale inta lagu jiro kala-goysyada flange-ka ah ee la sawiray.
Imtixaanka Adkaanta
Habka Tijaabada: ASTM A450 Qaybta 23. Adkaantu waa inaysan dhaafin 72 HRBW.
