Nā Hoʻohana ʻana o nā Papa Kila AH36, DH36, a me EH36 i nā Papahana Kūkulu Moku a me nā Papahana Ma waho o ka Moku

I loko o nā ʻoihana moana a me nā ʻoihana kai o ka honua, he kuleana koʻikoʻi nā papa kila i ka hōʻoia ʻana i ka kūpaʻa o ke kūkulu ʻana, ka palekana, a me ke ola lōʻihi o nā moku a me nā kahua e hana ana ma kekahi o nā wahi ʻino loa ma ka Honua. ʻO kekahi o nā mea i hoʻohana nui ʻiaNā papa kila AH36, DH36, a me EH36, nona ka māhele kila kūkulu ikaika kiʻekiʻe ma lalo o nā kūlana ASTM A131. Ua hana ʻia kēia mau papa e kū i nā ukana koʻikoʻi, nā hopena, a me nā kūlana kai ʻino, e lilo ai lākou i mea nui no ke kūkulu moku hou a me nā papahana ʻenekinia kai.

At sakyalloy, hāʻawi mākou i ka maikaʻi kiʻekiʻeNā papa kila AH36, DH36, a me EH36e hoʻokō ana i nā kūlana honua a hāʻawi i ka hana kūlike ma nā noi koi like ʻole.

1. ʻIkepili o nā Papa Kila AH36, DH36, a me EH36

ʻO AH36, DH36, a me EH36 he mau kila kai ikaika kiʻekiʻe i hoʻohana nui ʻia i ke kūkulu ʻana i nā moku a me nā hale ma waho. ʻO ka ʻokoʻa nui ma waena o kēia mau papa aia i ko lākounā koi paʻakikī hopenama nā mahana like ʻole:

  • AH36: Hoʻāʻo ʻia ma 0°C (paʻakikī o ka mahana o ka lumi)

  • DH36: Hoʻāʻo ʻia ma -20°C (paʻakikī haʻahaʻa)

  • EH36: Hoʻāʻo ʻia ma -40°C (paʻakikī wela haʻahaʻa loa)

Kaʻana like kēia mau papa i kahi ʻano kemika like a me nā waiwai mechanical, e hāʻawi ana i kahi hui kūpono oka ikaika hua (355 MPa ka palena iki)a meikaika tensile (490–620 MPa), ka mea e hōʻoiaʻiʻo ai i ka hiki ke hāpai i ke kaumaha kiʻekiʻe a me ke kū'ē ʻana i ka deformation.

2. Nā ʻano Kemika a me nā ʻano Mekanika

ʻO ka hoʻohuihui kemika o nā papa kila AH36, DH36, a me EH36 e komo pū me:

  • Kalapona (C):≤ 0.18%

  • Manganese (Mn):0.90–1.60%

  • Silika (Si):0.10–0.50%

  • ʻO ka phosphorus (P):≤ 0.035%

  • Sulfur (S):≤ 0.035%

Hiki i kēia mau kila ke loaʻa pū kekahinā mea hoʻohuihui liʻiliʻie like me niobium, vanadium, a me titanium e hoʻomaikaʻi i ka hoʻomaʻemaʻe ʻana o ka palaoa a hoʻoikaika i ka paʻakikī.

Nā waiwai mīkini:

  • Ikaika Hua: ≥ 355 MPa

  • Ikaika Hoʻopaʻa: 490–620 MPa

  • Elongation: ≥ 21%

  • Hoʻāʻo hopena Charpy V-notch: 0°C (AH36), -20°C (DH36), -40°C (EH36)

ʻO kēia hui pū ʻana o ka ikaika a me ka paʻakikī e ʻae i kēia mau papa e mālama i ka weldability maikaʻi loa a me ke ʻano i ka wā e hana ʻia ai.

3. Nā noi ma ka ʻoihana kūkulu moku

a. Kūkulu ʻana o ka ʻili o ka moku

ʻO ke kino ka iwi kuamoʻo o kekahi moku, e koi ana i nā mea e hiki ke kū i nā kaumaha compressive a me ke kūlou. Hoʻohana nui ʻia nā papa kila AH36, DH36, a me EH36 nouhi ʻana i ka ʻili o ka hull, nā hale papahele, a menā ʻāpana keel.

He kūpono kēia mau mea no:

  • Nā moku ipu a me nā moku ukana

  • Nā moku lawe ʻaila a me nā mea lawe LNG

  • Nā moku kaua a me nā moku kiaʻi

  • Nā moku holo ohua a me nā moku holo moana

ʻO ko lākou ikaika tensile kiʻekiʻe e hōʻoiaʻiʻo i ka hana maikaʻi loa ma lalo o ke kaumaha o nā ukana kaumaha a me nā kūlana kai haunaele.

b. Nā Palekana a me nā Hana Kiʻekiʻe

Ua koho pinepine ʻia nā papa DH36 a me EH36 no nā bulkheads a me nā superstructures ma muli o ko lākou hiki ke pale aku i ka haki palupalu i nā mahana haʻahaʻa, he mea koʻikoʻi loa ia noHoʻokele ʻĀketika or nā moku papa polar.

c. Nā Papa Hana a me nā Hoʻoikaika

ʻO ka maikaʻi loa o ka hiki ke hoʻopili ʻia o kēia mau kila e kūpono ai lākou no nā papa hoʻoikaika papahele, nā ʻano hana mōlina, a me nā ʻāpana halihali ʻē aʻe e koi ana i ke kūpaʻa kiʻekiʻe i ka luhi.

4. Nā noi ma waho a me ka ikehu

Ma waho aʻe o ke kūkulu moku, he kuleana koʻikoʻi ko nā papa kila AH36, DH36, a me EH36 inā papahana ʻenekinia kai a me ke kai, e like me:

a. Nā Paepae ʻAila a me ke Kinoea ma waho o ke kai

Hoʻohana ʻia kēia mau māka manā lako hoʻouka kaua, nā kahua semi-submersible, a me nā FPSO (nā ʻāpana mālama hana a me ka hoʻouka ʻana i nā ukana)ʻO ko lākou kūpaʻa i lalo o ka hopena a me ke kūpaʻa ʻana i ka pala i nā wahi wai paʻakai e kūpono ai lākou no nā papahele paepae, nā wāwae, a me nā kaola kākoʻo.

b. Nā ʻAno Hana Ikehu Makani

Me ka neʻe ʻana o ka honua i ka ikehu hou,nā mahi makani ma waho o ke kaike ulu wikiwiki nei. Hoʻohana pinepine ʻia nā papa kila EH36, me ka paʻakikī kiʻekiʻe, i lokonā kahua hale kiaʻi makani, nā monopile, a me nā ʻāpana hoʻololie kū i nā nalu kiʻekiʻe a me nā makani.

c. Nā Lako a me nā Paipu o lalo o ka Moana

I nā noi subsea, hoʻohana ʻia nā papa DH36 a me EH36 nonā kīʻaha kaomi, nā kākoʻo paipu, a me nā kiʻikuhi kūkulu kai, e hōʻoiaʻiʻo ana i ke kūpaʻa lōʻihi e kū'ē i ka luhi a me ka pala.

5. Hana Hana a me ka Hana Kuʻihao

ʻO kekahi o nā pono nui o nā papa kila AH36, DH36, a me EH36 ʻo ia ko lākouka hiki ke hoʻopili maikaʻi ʻia a me ka hanaHiki ke hoʻopili ʻia me ka hoʻohana ʻana i nā ʻano hana maʻamau e like me:

  • Kuʻihao Metal Arc Pale ʻia (SMAW)

  • Kuʻihao ʻAki Kinoea (GMAW)

  • Kuʻihao Arc Flux-Cored (FCAW)

ʻO kā lākou waiwai like kalapona haʻahaʻa (CEV) e hōʻoiaʻiʻo aika liʻiliʻi o ka pilikia o ka haki ʻanai ka wā o ka hoʻopili ʻana a me ke kūpaʻa kiʻekiʻe i ka brittleness o ka ʻāpana i hoʻopilikia ʻia e ka wela. ʻAʻole pono ka mālama wela ma hope o ka hoʻopili ʻana, kahi e wikiwiki ai ka hana ʻana a ʻoi aku ka maikaʻi o ke kumukūʻai.

At sakyalloy, ua kau ʻia nā papa āpau ika hoʻāʻo ʻana o ka ultrasonic, ka nānā ʻana i nā ana, a me ka hōʻoia ʻana o ka waiwai mechanicale hōʻoia i ka mālama ʻana me nā kūlana ASTM, ABS, LR, DNV, a me BV.

6. Ke kū'ē ʻana i ka palaho a me nā hana ʻili

ʻO ka hana ʻana ma nā wahi kai e hōʻike ana i nā hale kila i ka hoʻouka mau ʻia mai ka wai paʻakai, ka makū, a me nā mea haumia o ka lewa. Hōʻike nā kila AH36, DH36, a me EH36 i ke kūpaʻa maikaʻi i ka palaho ma muli o ka hoʻohuihui ʻana i kāohi ʻia a hiki ke pale hou ʻia ma o:

  • Ka pahū ʻana a me ka hoʻomaka ʻana

  • Nā uhi zinc a i ʻole epoxy

  • Nā ʻōnaehana palekana Cathodic

Hoʻolōʻihi kēia mau hana ʻili i ke ola lawelawe o nā moku a me nā kahua ma waho o ke kai, e hōʻemi ana i nā kumukūʻai mālama a pale i ka hōʻino ʻana o ke kūkulu ʻana.

7. Nā ʻae ʻana o ka Hui Hoʻokaʻawale

Ua ʻāpono ʻia nā papa kila AH36, DH36, a me EH36 e nā hui hoʻokaʻawale nui o ka honua holoʻokoʻa, e like me:

  • ABS (ʻOihana Hoʻouna Moku ʻAmelika)

  • LR (Kakau Inoa o Lloyd)

  • BV (Bureau Veritas)

  • DNV (Det Norske Veritas)

  • GL, RINA, a me NK

Hōʻoiaʻiʻo kēlā mau palapala hōʻoia e hoʻokō nā papa i nā kūlana koʻikoʻi o ka maikaʻi a me ka hana e pono ai no nā hale kai koʻikoʻi a me nā hale kai.

8. Nā Pōmaikaʻi o ka Hoʻohana ʻana iā AH36, DH36, a me EH36

  • Ka lakio ikaika-i-kaumaha kiʻekiʻehoʻemi i ke kaumaha holoʻokoʻa o ka moku, e hoʻomaikaʻi ana i ka pono o ka wahie.

  • Ka hiki ke hoʻopili maikaʻi loahoʻomaʻalahi i ke kaʻina hana hana a me ka hoʻoponopono ʻana.

  • ʻOi aku ka pale ʻana i ka hopenahōʻoiaʻiʻo i ka palekana a me ka hana ʻoiai i nā mahana hau.

  • Kūlana i hōʻoia ʻia a hiki ke hahai ʻiakūpono no nā kūlana hoʻokaʻawale moku honua.

  • Hoʻonā kūpono i ke kumukūʻaihoʻohālikelike ʻia me nā kila metala no nā pae hana like.

9. Nā mea kūʻai aku maʻamau a me nā mea hoʻohana hope loa

ʻO nā ʻoihana e hilinaʻi nui nei i nā papa AH36, DH36, a me EH36:

  • Nā hale hana moku a me nā mea hana moana

  • Nā ʻoihana ʻenekinia aila a me ke kinoea

  • Nā mea hoʻomohala ikehu hou ma waho o ka ʻāina

  • Nā ʻoihana hana pale kaua moana

  • Nā hale hana hana kaumaha

Ua hoʻolaha pono ʻia kēia mau mea i nā papahana ma ʻAsia, ʻEulopa, ka Hikina Waena, a me ʻAmelika.

10. No ke aha e koho ai iā sakysteel no nā hoʻonā kila moana

sakysteel(kahi mahele osakysteel) hāʻawi i kahi laulā piha o nā kila hana moku, me AH36, DH36, a me EH36, i loaʻa mai nā hale wili kaulana a loaʻa i nā ana, nā mānoanoa, a me nā kūlana ʻili i hana ʻia.

ʻO kā mākou mau pono:

  • Loaʻa piha me nā palapala hōʻoia EN 10204 3.2

  • Ka hoʻouna ʻana i ka manawa kūpono a me ke kākoʻo logistics honua

  • Kumukūʻai hoʻokūkū no nā kauoha nui a me nā kauoha papahana

  • Kākoʻo loea akamai a me ka lawelawe ma hope o ke kūʻai aku

Inā paha ʻoe e kūkulu ana i kahi moku hou a i ʻole e hana ana i nā kahua ma waho o ke kai,sakysteelhōʻoiaʻiʻo e loaʻa iā ʻoe ke kila pae moana e hoʻokō ai a ʻoi aku paha ma mua o kāu mau koi ʻenekinia.

Hopena

ʻO ka holomua o kekahi papahana kūkulu moku a i ʻole papahana kai e hilinaʻi nui ʻia ana i ka hilinaʻi o kāna mau mea kūkulu.Nā papa kila AH36, DH36, a me EH36ua hōʻoia iā lākou iho he iwi kuamoʻo o ke kūkulu ʻana i ke kai a me ke kai o kēia au, e hāʻawi ana i ka ikaika kūlike ʻole, ke kūpaʻa, a me ka hiki ke hoʻopili ʻia.

Ke hui pū nei mesakysteelʻo ia hoʻi ke koho ʻana i kahi mea hoʻolako hilinaʻi i hoʻopaʻa ʻia i ka maikaʻi, ka pololei, a me ka hana lōʻihi. Me ko mākou ʻike loea a me ka hiki honua, ua mākaukau mākou e kākoʻo i kāu papahana ʻenekinia moana e hiki mai ana me nā mea e kū i ka hoʻāʻo o ke kai.
