He mea kila kūikawā ka pahū pahū -pepa hao i hui pū ʻia me ka hana hōʻike pahū-. Mahalo i kāna hui like ʻole a me ka ʻenehana hana ʻenehana, hoʻohana nui ʻia ia i ka petrochemical, mining, construction, a me nā wahi hale kūʻai kahi e loaʻa ai nā pilikia flammable a pahū, e lawelawe ana ma ke ʻano he mea pale nui e hōʻoia i ka palekana o nā limahana a me nā lako. Hoʻohālikelike ʻia me nā ʻāpana kila maʻamau a me nā ʻili kila pahū maʻemaʻe, -pahū pahū maʻemaʻe, ʻoi aku ka nui o nā pōmaikaʻi i ka pahū-hōʻoiaʻiʻo, ke kū ʻana i ka corrosion, a me nā waiwai mechanical. Hoʻokō kāna mau hiʻohiʻona hana i nā koi o nā kūlana hana paʻakikī, e hui pū ana i ka pono a me ka palekana.
ʻO ka mea mua loa, ʻo ka hoʻokō koʻikoʻi koʻikoʻi a me ka hopena pahū hilinaʻi-ka pōmaikaʻi nui o nā pā hao pahū-pahū. ʻO kā lākou hana hōʻike pahū-ma muli o ka lākiō mea kūikawā a me ka hoʻolālā hoʻolālā. Hoʻohana nā papa i ka mea kiʻekiʻe -ikaika i hoʻopaʻa ʻia me ka hoʻomaʻamaʻa hōʻike pahū-ʻoihana, loaʻa ka hopena maikaʻi loa a me ka pale ʻana i ka pahū. Inā pahū, hiki i ka pā hao pahū -pono ke kū i ka nalu ha'alulu i hana 'ia e ka pahū, me ka pale 'ana i nā 'eha lua ma muli o ka weluwelu a me ka 'ōpala. I ka manawa like, hiki iā ia ke pale i ka laha ʻana o ke ahi, kūʻai i ka manawa no ka haʻalele ʻana i nā limahana a me ka pale ʻana i nā lako. Hoʻohālikelike ʻia me nā pā kila maʻamau, kūpono ia no nā ʻano hiʻohiʻona pahū{11}}like ʻole. Inā he pahū kinoea liʻiliʻi a i ʻole pahū lepo haʻahaʻa, hiki iā ia ke hāʻawi i ka pale a hōʻoia i ka palekana ma-paepae.
ʻO ka lua, loaʻa iā ia ke kūpaʻa corrosion maikaʻi loa, e hoʻonui nui i kona ola lawelawe. Hoʻokomo ʻia nā ʻili kila pahū pahū-pahū pahū-wela-a i ʻole ke anu-hoʻolou ʻia ma luna o ka ʻili o ka pahū-pahu. ʻO ka papa zinc he ʻano like a me ka paʻakikī, e hana ana i kahi pale pale maikaʻi e hoʻokaʻawale i nā mea corrosive e like me ka ea, ka wai, a me ka media acidic/alkaline, e pale ana i ka substrate mai ka ʻōpala a me ka ʻelemakule. Ke hoʻohālikelike ʻia me ka pahū ʻole -palapala kila hōʻoia, ua hoʻomaikaʻi maikaʻi ʻia kona kūpaʻa ʻana i ka ʻino, no laila kūpono ia no nā kaiapuni ʻino e like me nā hale kūʻai kahakai, nā hale hana kemika, a me nā mines lalo, kahi e ʻike ʻia ai i ka makū, ka ea ākea, a me ka ʻino kemika. Hoʻopau ia i ka pono no ka mālama ʻana i nā -corrosion mau, hoʻolōʻihi i kona ola lawelawe ma 3-5 mau manawa a hoʻemi nui i nā kumukūʻai mālama ma hope.
Loaʻa i nā ʻili kila pahū pahū -pahū puʻupuʻu i nā mea mekini maikaʻi loa, e hōʻike ana i ka ikaika kiʻekiʻe a me ka ʻoʻoleʻa maikaʻi, no laila kūpono lākou no nā hiʻohiʻona hoʻonohonoho like ʻole. Hana ʻia ka mea kumu o ka pahū pahū -pahū pahū uʻi kiʻekiʻe-ke kila kalapona a i ʻole ke kila kila, i hana ʻia ma o ka ʻōwili ʻana a me ka hoʻomaʻamaʻa ʻana i ka wela, e loaʻa ai ka ikaika tensile maikaʻi loa, ka ikaika hāʻawi, a me ka paʻakikī o ka hopena, e pale ai i ka deformation a me ka haki. I ka manawa like, ʻaʻole pili ke kaʻina hana galvanizing i nā waiwai mechanical o ka mea kumu, e hāʻawi ana i nā pahū -hōʻoia a me ka hoʻouka- hiki. Hiki ke hoʻohana pololei ʻia no ka pale ʻana i ka pā, nā hale lako, nā pani pahū a me nā puka makani, a me nā mea ʻē aʻe, me ka hoʻolako ʻana i ka pale pahū a me ka hiki ʻana o ka ukana. Eia kekahi, ʻo kā lākou paʻakikī maikaʻi loa e hiki ai ke ʻoki, kulou, a me ke kuʻi ʻana e hoʻokō i nā koi hoʻonohonoho like ʻole, hoʻololi i nā ʻano nui a me nā ʻano like ʻole, e hāʻawi ana i ka maʻalahi o ke kūkulu ʻana.
Eia kekahi, ua kūpaʻa ʻo ia i nā wela kiʻekiʻe a me ka ʻelemakule, kūpono ia no nā wahi hana paʻakikī. Loaʻa i nā ʻāpana kila pahū pahū -pahū puʻupuʻu maikaʻi loa-elike mehana, e hana paʻa ana i loko o ke ana wela o -40 degere a 600 degere me ka hoʻohaʻahaʻa ʻole o ka hana ma muli o ka hoʻololi ʻana i ka mahana, no laila kūpono lākou i nā hiʻohiʻona hana wela kiʻekiʻe e like me ka metallurgy a me ka paila paila. I ka manawa like, hō'ike kona papa zinc ili i nā waiwai kū'oko'a maika'i loa, e kū'ē ana i ka 'ili a me ka pohā ma hope o ka -loa'a lō'ihi i ka lā, ka ua, a me nā wahi kūlohelohe 'ē a'e, e mālama mau ana i ka hana pale no ka manawa lō'ihi. Ke hoʻohālikelike ʻia i nā ʻāpana kila pahū maʻamau, hāʻawi ia i ka hoʻololi ʻana i ke kaiapuni, kūpono no nā ʻano hana paʻakikī a paʻakikī hoʻi, e hoʻopau ana i nā hopohopo e pili ana i nā mea kaiapuni e pili ana i kāna hana.
