He aha ke ʻano o ka pā hao ʻo Pressure Vessel?
Uhi ka ipu kila i ka nui o nā māka kila i hoʻolālā ʻia no ka hoʻohana ʻana i ka ipu kaomi, nā paila, nā hoʻololi wela a me nā moku ʻē aʻe i loaʻa i ke kinoea a i ʻole ka wai i nā kaomi kiʻekiʻe. ʻO nā hiʻohiʻona maʻamau, ʻo ia nā pahu hau no ka kuke ʻana a me ka wili, nā pahu oxygen no ka luʻu ʻana a me ka nui o nā pahu metala nui āu e ʻike ai i loko o kahi mea hoʻomaʻemaʻe aila a mea kanu kemika. Nui nā ʻano kemika like ʻole a me ka wai i mālama ʻia a hana ʻia ma lalo o ke kaomi. ʻO kēia mau mea mai nā mea maʻalahi e like me ka waiū a me ka aila pāma i ka aila ʻaila a me ke kinoea maoli a me kā lākou distillates i nā waikawa lethal a me nā kemika e like me ka methyl isocyanate. No laila o kēia mau kaʻina hana pono ke kinoea a i ʻole ka wai e wela loa, aʻo nā mea ʻē aʻe i loaʻa ia i nā wela haʻahaʻa loa. ʻO ka hopena, aia nā ʻano ʻokoʻa like ʻole o nā māka kila moku e kū ana i nā hihia hoʻohana like ʻole.
Ma keʻano laulā, hiki ke hoʻokaʻawale ʻia kēia i ʻekolu mau pūʻulu. Aia kekahi pūʻulu o nā māka ipu hao hao. He mau kila maʻamau kēia a hiki ke hoʻokō i nā noi he nui kahi haʻahaʻa haʻahaʻa a me ka wela haʻahaʻa. ʻOiai ʻoi aku ka hopena o ka wela a me ka corrosion i nā pā kila chromium, ua hoʻohui ʻia ka molybdenum a me ka nickel e hāʻawi i ke kūʻē hou aku. ʻO ka mea hope loa e like me ka piʻi ʻana o ka chromium, nickel a me molybdenum, loaʻa iā ʻoe nā papa kila kuʻikuʻi kūʻokoʻa i hoʻohana ʻia i nā noi koʻikoʻi a kahi e pale ʻia ai ka hoʻohaumia ʻana o ka oxide - e like me ka ʻoihana meaʻai a me nā lāʻau lapaʻau.
ʻO ke kūlana o ka paʻi hao moku

Hoʻohana ʻia i ka pā hao hao
● A516 pā kila he kalapona kila me nā kikoʻī no nā pā ipu kaomi a me ka lawelawe wela haʻahaʻa a haʻahaʻa paha.
● Hoʻohana ʻia ʻo A537 i ka wela a ma muli o ka hopena, hōʻike i ka hua nui a me ka ikaika tensile ma mua o nā māka A516 maʻamau.
● Hoʻohana ʻia ʻo A612 no ka hoʻohana ʻana i nā moku kaomi wela haʻahaʻa.
● A285 nā papa kila i manaʻo ʻia no ka fusion-welded kaomi ʻana a me nā papa i hoʻolako maʻamau i nā kūlana like-rolled.
● TC128-grade B ua maʻamau a hoʻohana ʻia i nā kaʻa pahu kaʻaahi i kaomi ʻia.
ʻO nā mea hoʻohana ʻē aʻe no ka paila a me ka paomi moku

Aia ka ikaika o JINDALAI i ka ipu hao kikoo kiʻekiʻe loa i hoʻohana ʻia i ka ʻoihana ʻaila a me ke kinoea a ʻoi aku hoʻi i ka pā kila i kū i ka Hydrogen Induced Cracking (HIC) kahi i loaʻa iā mākou kekahi o nā waiwai nui loa o ka honua.
