Nā kahua noi o nā mea hoʻohui kūikawā i ka ʻoihana ʻaila o nā paipu kila kila

ʻO ka ʻimi ʻana a me ka hoʻomohala ʻana i ka aila he ʻoihana multidisciplinary, ʻenehana- a me ke kapikala nui e pono ai ka nui o nā mea metala a me nā huahana metallurgical me nā waiwai like ʻole a me nā hoʻohana. Me ka hoʻomohala ʻana i nā luawai ʻaila ultra-hohonu a ultra-inclined a me nā ʻaila aila a me nā māla i loaʻa iā H2S, CO2, Cl-, etc., ke hoʻonui nei ka hoʻohana ʻana i nā mea kila kila me nā koi anti-corrosion.

ʻO ka hoʻomohala ʻana o ka ʻoihana petrochemical ponoʻī a me ka hana hou ʻana o nā mea hana petrochemical ua kau aku i nā koi kiʻekiʻe e pili ana i ka maikaʻi a me ka hana ʻana o ke kila kila, e koi ana i ke kila kila e pale i ka corrosion a kū i nā wela kiʻekiʻe a haʻahaʻa. ʻAʻole hoʻomaha nā kūlana akā ʻoi aku ka paʻakikī. I ka manawa like, ʻo ka ʻoihana petrochemical kahi ʻoihana wela kiʻekiʻe, kiʻekiʻe kiʻekiʻe, a me nā mea ʻawaʻawa. He ʻokoʻa ia mai nā ʻoihana ʻē aʻe. ʻAʻole maopopo ka hopena o ka hoʻohana ʻana i nā mea. Ke hiki ʻole ke hōʻoia i ka maikaʻi o nā mea kila kila i loko o ka ʻoihana petrochemical, e pōʻino nā hopena. No laila, pono e hoʻomaikaʻi i nā ʻoihana ʻenehana a me ka waiwai hoʻohui o kā lākou huahana i ka wā e hiki ai ke noho i ka mākeke huahana kiʻekiʻe.

ʻO ka mākeke kūpono o ka ʻoihana petrochemical nā paipu nui-diameter no nā kapuahi ʻaila a me nā paipu hoʻoili haʻahaʻa haʻahaʻa. Ma muli o kā lākou koi kūikawā wela a me ka corrosion a me ka hoʻonohonoho pono ʻole ʻana a me ka mālama ʻana, pono nā mea hana e loaʻa i kahi pōʻai ola lawelawe lōʻihi, a pono e hoʻomaikaʻi ʻia nā waiwai mechanical a me ka hana o nā paipu ma o ka mana haku mele a me nā ʻano hana wela kūikawā. . ʻO kekahi mākeke ʻē aʻe he paipu kila kūikawā no ka ʻoihana fertilizer (urea, phosphate fertilizer), ʻo nā māka kila nui ʻo 316Lmod a me 2re69.

Hoʻohana maʻamau i nā reactors i nā lako petrochemical, nā paipu aila, nā koʻokoʻo i poni ʻia i loko o nā pūnāwai aila corrosive, nā paipu spiral i loko o nā kapuahi petrochemical, a me nā ʻāpana o ka ʻaila a me nā lako wili kinoea, etc.

Hoʻohana ʻia nā ʻāpana kūikawā maʻamau i ka ʻoihana ʻaila:

Ke kila kila: 316LN, 1.4529, 1.4539, 254SMO, 654SMO, etc.
Pākuʻi wela kiʻekiʻe: GH4049
Pākuʻi nickel: Alloy 31, Alloy 926, Incoloy 925, Inconel 617, Nickel 201, etc.
Pākuʻi pale ʻino: NS112, NS322, NS333, NS334
