Q1: He aha ka meaPuʻu paipu kila ASTM A252?
He paipu kila hoʻohana lākou no ka hoʻohana ʻana i ka ʻeli ʻana, nā kahua, nā alahaka, nā uapo, a me ke kahua hana kūkulu.

Q2: He aha nā māka i loko o ka waihona?
Papa 1, 2, a me 3 - Pili ʻo Gr.1 no ka ukana māmā, ʻo Gr.2 no ke kūkulu hale maʻamau, ʻo Gr.3 no ka hoʻomaloʻo hana kaumaha.

Hoʻopili ʻia me nā kaula kila
Ka lawe nui ʻana a i ʻole nā pallets lāʻau.
Me nā pāpale hopena a me ka mālama anti-rust

Q7: Hiki iaʻu ke loaʻa nā nui maʻamau?
ʻAe, hiki iā mākou ke hāʻawi iā ʻoe i nā diameters maʻamau, ka lōʻihi a me nā māka no kāu papahana.

Q8: Pehea e koho ai i ka māka kūpono?
Ma muli o ka hiki ke kau i ka ukana, ke kūlana o ka lepo a me ka hoʻohana ʻana i ke kūkulu ʻana. Kākoʻo mai ka ʻenekinia.
