Chifukwa Chake AH36, DH36, ndi EH36 Ndi Ofunika Kwambiri Mu Makampani Oyendetsa Zam'madzi

1. Chiŵerengero Chapamwamba Cha Mphamvu-Kulemera

Chimodzi mwa ubwino waukulu wa magiredi awa ndimphamvu zambiri pamodzi ndi kulemera kochepaIzi zimathandiza opanga zombo kupanga ma shells opepuka popanda kuwononga chitetezo. Zotsatira zake ndikugwiritsa ntchito bwino mafuta, mphamvu yonyamula katundu wambiri, komanso kuchepetsa mpweya woipa, mogwirizana ndi zolinga zamakono zosamalira zachilengedwe.

2. Kulimba Kwambiri Kotsika Kwambiri

Zombo zomwe zimagwira ntchito m'madera ozizira kapena m'madzi akumpoto zimafuna zinthu zomwe zimasunga kulimba kutentha kwapansi pa zero. Makamaka DH36 ndi EH36 zimayesedwa kuti ziwone ngati zikulimbana ndi kugwedezeka pa-20°C ndi -40°C, kuonetsetsakukana kusinthasintha kwa kutentha ndi kusweka kwa ming'alungakhale m'malo ozizira kwambiri.

3. Kukana Kwambiri Kudzimbiritsa

Madzi amchere ndi chinyezi zimathandizira dzimbiri, zomwe zingawononge kapangidwe ka sitimayo. Kapangidwe ka mankhwala a AH36, DH36, ndi EH36 kamaperekakukana kwambiri dzimbiri ndi okosijeni, kukulitsa nthawi yogwira ntchito ya zombo ndikuchepetsa ndalama zokonzera.

4. Kutha Kusenda Bwino Kwambiri ndi Kusavuta Kupanga

Zitsulo izi zimawoneka bwino kwambirikusinthasintha popanda kutentha, chifukwa cha mtengo wawo wotsika wa kaboni (CEV). Zitha kulumikizidwa pogwiritsa ntchitoSMAW, GMAW, kapena SAWnjira zopangira popanda kuwononga mphamvu kapena magwiridwe antchito a zomangamanga. Izi zimapangitsa kuti zikhale zoyenera kwambiri popanga zombo zazikulu.

5. Kukana Kutopa ndi Kugwedezeka

Zombo za m'madzi nthawi zonse zimakumana ndi mavutokupsinjika kwa mafunde, kuyenda kwa katundu, ndi kugwedezeka kwa kayendedwe ka mphamvuZitsulo za AH36, DH36, ndi EH36 zili ndi mphamvu yolimba kwambiri, zomwe zimathandiza kupewa kung'ambika pang'ono komanso kuonetsetsa kuti zimakhala zolimba kwa nthawi yayitali munthawi yovuta yogwirira ntchito.

6. Kutsatira Malamulo Ovomerezeka a Ubwino ndi Miyezo Yapadziko Lonse

Magiredi onse atatu avomerezedwa ndi mabungwe akuluakulu ogawa magulu:

• Bungwe la Kutumiza la ku America (ABS)

• Kaundula wa Lloyd (LR)

• Det Norske Veritas (DNV)

• Bureau Veritas (BV)

• Bungwe Logawa Magulu la China (CCS)

Izi zimatsimikizira kuti mbale zachitsulo zimaperekedwa ndisakysteelkukwaniritsa zofunikira za chitetezo padziko lonse lapansi komanso magwiridwe antchito popanga zombo ndi mainjiniya apanyanja.

Kugwiritsa Ntchito Mapangidwe Amphamvu a Madzi a M'nyanja

1. Ntchito Yomanga Sitima Zapamadzi

Ma plate a AH36 ndi DH36 amagwiritsidwa ntchito kwambiri munyumba zomangira matumba, madesiki, ndi mafelemu a zombo zonyamula katundu, matanki, ndi zombo zonyamula zinthu. Mphamvu zawo zimathandiza kupirira kupsinjika kwa mafunde ndi katundu wogunda popanda kusintha.

2. Mapulatifomu a Mafuta ndi Gasi Ochokera Kunja

Chitsulo cha EH36, chokhala ndi kulimba kwake kwapamwamba kwambiri kutentha kochepa, ndi chabwino kwambirizida zobowolera zinthu zakunja kwa dziko, malo osungiramo zinthu zoyandama ndi kutsitsa katundu (FPSO)ndinsanja za pansi pa nyanjazomwe zimagwira ntchito m'malo ovuta a m'nyanja.

3. Zombo za LNG ndi Polar

Mapepala achitsulo a EH36 amakhala ndi ductility yabwino kwambirimatenda a cryogenic, kuwapangitsa kukhala oyenerazonyamulira mpweya wachilengedwe wosungunuka (LNG), zombo zophwanyira ayezi, ndi zombo zoyendera za ku Arctic.

4. Mapulogalamu Okhudza Nkhondo Yapamadzi ndi Chitetezo

Chifukwa cha kuphatikiza kwawo mphamvu, kapangidwe kopepuka, komanso kukana kugunda, zitsulozi zimagwiritsidwa ntchito kwambiri muasilikali ankhondo a panyanja, zombo zolondera, ndi zombo zodzitetezera, kuonetsetsa kuti nkhondoyo ndi yokonzeka bwino komanso kuti ingathe kuyendetsedwa bwino.

5. Mphepo ndi Zomangamanga za M'nyanja za M'mphepete mwa Nyanja

AH36, DH36, ndi EH36 amagwiritsidwanso ntchito mumaziko a ma turbine amphepo a m'mphepete mwa nyanja, makina omangira, ndi mafelemu othandizira, komwe amapereka mphamvu yolimbana ndi kutopa ndi dzimbiri kwa nthawi yayitali pansi pa nyengo yosinthasintha ya nyanja.

Ubwino Wosankha Zitsulo Zam'madzi za Sakysteel

Monga wopanga waluso komanso wogulitsa kunja zitsulo za m'madzi ndi za m'mphepete mwa nyanja,sakysteelimapereka khalidwe losayerekezeka la malonda ndi chithandizo kwa makasitomala:

• Mitundu yonse yamakulidwe (5–150 mm)ndim'lifupi (mpaka 3,500 mm)

• Chitsimikizo kuchokeraABS, LR, DNV, BV, ndi CCS

• Miyeso Yopangidwira ndi Ntchito Zodula

• Kutumiza mwachangu ndi ma CD oyenera kuyenda panyanja

• Netiweki yapadziko lonse lapansi yoperekera zombo ndi mapulojekiti akunyanja

Ndisakysteel, makasitomala amatha kudalira mbale zachitsulo za AH36, DH36, ndi EH36 zapamwamba kwambiri zomwe zimakwaniritsa zofunikira kwambiri pakugwira ntchito komanso chitetezo chamakampani apadziko lonse lapansi.

Zochitika Zamtsogolo mu Kugwiritsa Ntchito Zitsulo Zam'madzi

Tsogolo la zomangamanga za sitima ndi uinjiniya wa m'mphepete mwa nyanja likupangidwa ndi kupita patsogolo kwazipangizo zopepuka, zosagwiritsa ntchito mphamvu zambiri, komanso zokhalitsaPamene zombo zikukula komanso zapadera zikuchulukirachulukira, kufunikira kwazitsulo zotsika mtengo kwambirimonga AH36, DH36, ndi EH36 zikupitirira kukwera.

Mapulogalamu atsopano ndi awa:

• Zombo zoyendera zosakanikiranakufunikira zipangizo zoyezera kulemera kwa thupi

• Ma migodi akuya ndi malo ofufuzirayomangidwa kuti igwiritsidwe ntchito m'malo ovuta kwambiri

• Ukadaulo wotumiza zinthu zobiriwira, kumene zitsulo zosagwira dzimbiri zimachepetsa kukonza ndi kutulutsa mpweya woipa

Zatsopano zopitilira mu kukonza zitsulo — mongakupondaponda ndi kuyika ma microalloying pogwiritsa ntchito thermo-mechanical— akutsimikizira kuti magiredi awa adzakhala patsogolo pa uinjiniya wapamadzi kwa zaka zambiri zikubwerazi.
