Ke kūpaʻa ʻana i ka palaho maikaʻi loa

2205 Kaula uea kila kila Duplexhāʻawi i kahi lele koʻikoʻi i ke kūpaʻa ʻana i ka pala ma luna o nā kila kila maʻamau - ʻoi aku hoʻi i nā wahi i loaʻanā chloride, nā waikawa, a i ʻole nā ​​​​​​kemika alkaline.

Nā Pōmaikaʻi Hana:

• Ke kū'ē'ē'ana i ka palaho a me ka lua:
  ʻO ke kiʻekiʻe o ka chromium (22%) a me ka molybdenum (3%) e hāʻawi i ke kūpaʻa ikaika i ka pala kūloko i loko o ka wai kai a me nā kūlana saline.

• Ke kū'ē ʻana i ka palaho kaumaha (SCC):
  Hoʻopaʻa ka pae ferritic o Duplex i ka hoʻokumu ʻana o nā māwae i nā wahi chloride kahi e hāʻule pinepine ai ʻo 304 a me 316.

• Ke kū'ē ʻana i ka waikawa a me ka alkaline:
  Hana maikaʻi loa i nā ʻano waikawa e like me ka sulfuric a me nā phosphoric acid, a me nā hopena caustic soda a me ka brine.

ʻO kēia mau waiwai e hana ai i ke kaula uea 2205 i mea kūpono nonā hale hana ʻaila ma waho o ke kai, ke kūkulu moku, nā hale hana desalination, a me nā hale mālama kemika— nā mea a pau e kū nei i ka pilikia mau i nā wahi ʻino.

ʻOi aku ka luhi a me ke kūpaʻa ʻana i ka ʻaʻahu

Ua pili nā kaula uea i nā hana moana a me waho i nāka hoʻouka ʻana o ka pōʻaiapuni, kūlou, a me ka haʻalulu. I ka hala ʻana o ka manawa, hiki i kēia mau koʻikoʻi hoʻoikaika ke hana i nā microcracks a me nā hemahema luhi i nā kila kila kuʻuna.

2205 Kaula uea duplex, me kona ikaika hua kiʻekiʻe a me ka microstructure dual-phase, hōʻike:

• ʻOi aku ka pale ʻana i ka luhima lalo o ka hoʻouka hou ʻia ʻana.

• Hoʻonui ʻia ka hana ʻaʻahu, e hōʻemi ana i ka hōʻino ʻana o ke kaula a me ka palaho ʻana o ka ʻili.

• Ola lawelawe lōʻihi, ʻoiai ma lalo o ka neʻe mau ʻana a me ke kaumaha.

ʻO kēia ka mea e koho ai i nā kaula uea Duplex nonā winches, nā kaula hoʻopaʻa, nā kaula ROV, nā cranes, a me nā ʻōnaehana hāpaie hana ana 24/7 i nā kūlana koi ma waho.

Ke kū'ē ʻana i ka haki ʻana o ka palaho kaumaha (SCC)

ʻO kekahi o nā nāwaliwali nui o nā kila kila 304 a me 316 ʻo iaka haki ʻana o ka palaho kaumaha i hoʻoulu ʻia e ka chloride— he hāʻule koke a palupalu hoʻi e hiki ke hana ma lalo o ke koʻikoʻi tensile i ke alo o ka wai paʻakai a i ʻole ka haumākū.

2205 Ke kila kila ʻeluahoʻopau loa i kēia pilikia:

• ʻO kapae ferriticpale i ka hoʻomaka ʻana o ka haki.

• ʻO kapae austeniticmālama i ka maʻalahi a me ka paʻakikī.

Hāʻawi kēia hui pū ʻana i ke kū'ē koʻikoʻi i ka SCC, e hōʻoiaʻiʻo ana i ka palekana a me ke kūpaʻa no ka wā lōʻihinā ʻōnaehana hoʻopaʻa, heleuma, a me ke kākoʻo uweai hōʻike ʻia i ka wai kai a me nā kūlana haumākū.
