Nā Paipu Kila Hana ʻOleNā noi
ʻOihana ʻAila a me ke Kinoea:

Ka lawe ʻana i ka ʻaila, ke kinoea, a me nā wai ʻē aʻe ma lalo o ke kaomi kiʻekiʻe a me ka mahana.

Nā Hale Hana Mana:

Hoʻohana ʻia i loko o nā ʻōnaehana boiler a me nā mea hoʻololi wela.

ʻOihana Petrochemical:

No ka hana ʻana a me ka lawe ʻana i nā kemika a me nā hydrocarbons.

Nā ʻōnaehana paipu ʻoihana:

Ma nā ʻōnaehana paipu wela kiʻekiʻe a me ke kaomi kiʻekiʻe like ʻole.

Nā Paipu Kila Hana ʻOle ASTM A106Nā Pōmaikaʻi
Hana Hana Mahana Kiʻekiʻe:

Kūpono no nā noi e pili ana i nā mahana kiʻekiʻe ma muli o kona mau ʻano mea.

Ikaika a me ke kūpaʻa:

Hāʻawi ke kūkulu ʻana me ka humuhumu ʻole i ka ikaika a me ka hilinaʻi kiʻekiʻe ma mua o nā paipu i hoʻopili ʻia.

Ke kū'ē ʻana i ka palaho:

Ke kūpaʻa maikaʻi nei i ka pala o loko a me waho, ʻoiai ke uhi ʻia a hoʻopaʻa ʻia paha.

Ka maʻalahi:

Loaʻa i nā nui like ʻole a me nā mānoanoa e hoʻokō ai i nā koi ʻoihana like ʻole.
