Hoʻokaʻawale ʻia nā paipu kalapona kalapona 40 ma muli o ka hui pū ʻana o nā mea e like me ka ratio mānoanoa o ke anawaena-a-pā, ka ikaika waiwai, ke anawaena o waho, ka mānoanoa o ka pā, a me ka hiki ke kaomi.
ʻO ka hoʻonohonoho hoʻonohonoho, e like me ka Hōʻike 40, e hōʻike ana i kahi hui kūikawā o kēia mau mea. No nā paipu Hōʻike 40, ʻike pinepine lākou i ka mānoanoa o ka pā, e hōʻike ana i ke kaulike ma waena o ka ikaika a me ke kaumaha. Hiki ke ʻokoʻa ke kaumaha o ka paipu ma muli o nā kumu e like me ke ʻano kikoʻī o ke kila kalapona i hoʻohana ʻia, ke anawaena, a me ka mānoanoa o ka pā.
Hiki i ka hoʻohui ʻana i ke kalapona i ke kila ke hoʻopili i ke kaumaha, me ka ʻoi aku ka nui o ke kalapona i loaʻa i nā paipu māmā. Eia naʻe, pāʻani koʻikoʻi ka mānoanoa o ka pā a me ke anawaena i ka hoʻoholo ʻana i ke kaumaha.
Manaʻo ʻia ka Papa 40 he papa puʻe haʻahaʻa, kūpono no nā noi like ʻole kahi e koi ʻia ai nā helu kaomi haʻahaʻa. Inā makemake ʻoe i ka ʻike kikoʻī a i ʻole ke kōkua e pili ana i ka Hōʻike 40 paipu kila carbon, e ʻoluʻolu e kelepona mai iā mākou no ke kōkua hou aku.

ʻO ka papahana 40 ka paipu kalapona kalapona he paipu maʻamau i hoʻohana ʻia i ka ʻoihana kūkulu. E pili ana ia i ka mānoanoa o ka pā paipu a he ʻāpana ia o kahi ʻōnaehana maʻamau i hoʻohana ʻia no ka hoʻokaʻawale ʻana i nā paipu ma muli o ko lākou mānoanoa o ka paia a me ka hiki ke kaomi.
Ma ka ʻōnaehana Hōʻike 40:
- ʻO ka "Schedule" e pili ana i ka mānoanoa o ka paia o ka paipu.
- ʻO ka "carbon steel" e hōʻike ana i ke ʻano o ka paipu, ʻo ia ka carbon a me ka hao.
Hoʻohana maʻamau ʻia nā paipu kila kalapona Hōʻike 40 no nā noi like ʻole, me ka lawe ʻana i ka wai a me ke kinoea, ke kākoʻo hana, a me nā kumu ʻoihana maʻamau. ʻIke ʻia lākou no ko lākou ikaika, lōʻihi, a me ka versatility, e hoʻolilo iā lākou i koho kaulana i nā hana hana a me nā ʻenehana.
