ʻO nā wahi paʻakikī o kēia mau wili e hana like me kahi drill bit a pēlā e hiki ai ke ʻoki pololei ma o kahi ʻāpana kila kila. Hiki ke hoʻohana ʻia a hiki i ʻelua ʻāpana o ke kila kila me ka mānoanoa o 1mm kēlā me kēia no ka mānoanoa holoʻokoʻa o 2mm a kūpono hoʻi no ka hoʻohana ʻana me ka papa 316 a i ʻole ka lau.

ʻO kā mākou mau mea hoʻopaʻa Bi-metal ʻelua ʻano kila. Hana ʻia ka drill-point a me nā kaula paʻi mua o ka wili mai 1022 carbon steel i mālama ʻia i ka wela e hōʻoiaʻiʻo i ka hana wili nani. Hoʻokumu ʻia ke kino screw me ka ʻāpana poʻo mai ke kila stainless A2 i hōʻike ʻia e kona kūpaʻa maikaʻi loa.

Hoʻopili pū ʻia nā metala ʻelua a ma muli o ka hopena ua hana lākou i kahi wili i ʻoi aku ka maikaʻi o nā ao ʻelua - nā mana wili maikaʻi a me ke kū ʻana o ka corrosion. Hoʻopili ʻia nā wili i ka zinc-plated no ka pale ʻana i ke kiko kila kalapona mai ka ʻino ʻana, me ka ʻike ʻole ʻia o ka wili mai kahi wili kila kalapona i hoʻopaʻa ʻia.

HOOMAIKAI

No nā makahiki he ʻumi, ua manaʻo ʻia ʻo AISI 304 a me AISI 316 Austenitic Stainless Steel ka mea mua, poʻokela a wale nō i koho ʻia ma ʻAmelika ʻĀkau no ka hoʻohana ʻana i waho ma kahi ʻano paʻakikī; kahakai a me nā wahi ʻoihana, etc.

ʻO ka maikaʻi o ka Austenitic Stainless Steel i loko o Chromium a me Nickel a me Molybdenum no AISI 316 he mau hana corrosion maikaʻi loa a ma ka manawa like me ka ductile loa me ka pilikia ʻole o ka Hydrogen Assisted Stress Corrosion Cracking (HASCC) a i ʻike ʻia ʻo Hydrogen Embrittlement.

Ua hoʻomohala ka poʻe akamai o ka honua i nā ʻenehana forging anu kūpono no ka hoʻokō ʻana i kahi kaʻina hana maikaʻi me ka maikaʻi o ka huahana kiʻekiʻe me nā keʻena paʻi maikaʻi no ka paʻi ʻana iho, e like me ka maʻamau #1/4 -1-3/4” me ke poʻo 3/8” i hoʻohui ʻia he AISI 304 a i ʻole AISI 316 kila kila EPDM.

EFFICIENCY = NA PALAPALA LU

ʻO kahi mea hoʻololi pāʻani ma ka ʻoihana hoʻopaʻa ʻana ʻo ia ka mea i hana ʻia i nā wili hoʻoheheʻe ponoʻī, i hoʻopōkole i nā kaʻina hana i nā lōʻihi loa.

Eia naʻe, ʻaʻole hiki ke hoʻopaʻakikī ʻia nā wili kila kila ʻole AISI 300, ʻo nā mea hiki ke hana i nā wili selfdrilling me nā kiko drill paʻakikī no ka wili ʻana i ke kila ua kaupalena ʻia i nā mea paʻa i hana ʻia mai ke kila.
