ʻO ka paipu i kauoha ʻia ma lalo o kēia kikoʻī e hoʻohana nui ʻia no ka paipu i hoʻopaʻa ʻia i kahi mahana ma luna o 350 ℃. No ka laʻana: lawe ʻana i ka mahu, wai etc.
Ma ke kaʻina hana ʻole: pau wela a pau ke anu
Hoʻopili ʻia ke kūpale uila
Hana ʻia: paipu liʻiliʻi (hoʻopau wela a pau ʻole paha) / paipu welded pale uila
Nui: OD: 15.0～660mm WT: 2~50mm
Papa:STPT370 ,STPT410,STPT480
Length: 6M a i ʻole ka lōʻihi i ʻōlelo ʻia e like me ka makemake.
Wela: Wela Plain, Hope Beveled.
