Katundu Wofunika ndi Ubwino wa Mapepala Achitsulo Omanga Sitima a AH36, DH36, ndi EH36

Giredi	Mphamvu Yochepa Yopereka (MPa)	Kutentha kwa Mayeso a Impact	Mapulogalamu Odziwika
AH36	355	0°C	Ma shells ndi ma decks ambiri a sitima
DH36	355	-20°C	Mapulatifomu a m'mphepete mwa nyanja, nyumba zomangidwa ndi zitseko zomwe zimakhudzidwa ndi madzi ozizira
EH36	355	-40°C	Zombo za Arctic, zonyamulira LNG, ndi zomangamanga za m'nyanja yakuya

Magiredi onse atatu ali ndi zofananakapangidwe ka mankhwala ndi mphamvu yokoka, koma EH36 ili ndi mulingo wapamwamba kwambiri wa kulimba, zomwe zimapangitsa kuti ikhale yoyenera kwambiri m'malo ovuta kwambiri.

Kapangidwe ka Mankhwala a AH36, DH36, ndi EH36

Kapangidwe kake koyenera bwino ka zitsulo zimenezi kamapereka chisakanizo chabwino kwambiri champhamvu, kusinthasintha, ndi kukana dzimbiri.

Kapangidwe ka Mankhwala (%):

• Kaboni (C):≤ 0.18

• Manganese (Mn):0.90–1.60

• Silikoni (Si):0.10–0.50

• Phosphorus (P):≤ 0.035

• Sulfure (S):≤ 0.035

• Niobium (Nb), Vanadium (V), Titanium (Ti):≤ 0.10 (zinthu zazing'ono zopangira mphamvu)

Kusakaniza kwa micro-alloying ndi Nb, V, ndi Ti kumathandiza kukonza kapangidwe ka tirigu wa chitsulocho, ndikuwonjezera kwambiri magwiridwe antchito ake amakina komanso kulimba kwake.

Katundu wa Makina

Ubwino waukulu wa zitsulo za AH36, DH36, ndi EH36 uli m'gulu lapamwamba kwambiri.mphamvu yamakinandikulimba mtima pansi pa katundu wovuta.

Katundu Wamba wa Makina:

• Mphamvu Yopereka:≥ 355 MPa

• Kulimba kwamakokedwe:490–620 MPa

• Kutalika (mu 50 mm):≥ 21%

• Mphamvu Yokhudza Mphamvu ya Charpy V-Notch:

  • AH36: yayesedwa pa 0°C

  • DH36: yayesedwa pa -20°C

  • EH36: yayesedwa pa -40°C

Katunduyu amatsimikizira kuti ma shells a sitima ndi zida zake zimatha kupirirakupindika kwakukulu, kugwedezeka, ndi mphamvu zogundapamene tikusunga umphumphu m'malo ozizira komanso owononga madzi a m'nyanja.

Katundu ndi Ubwino Wofunika

1. Chiŵerengero Champhamvu Kwambiri Kulemera

Zitsulo za AH36, DH36, ndi EH36 zimakhala ndi mphamvu zambiri poyerekeza ndi zitsulo wamba za kaboni, zomwe zimathandiza opanga zombo kupanga mapangidwe.zopepuka koma zolimbaIzi zimapangitsa kuti katundu azinyamula bwino komanso kuti mafuta azigwiritsidwa ntchito bwino.

2. Kulimba Kwambiri pa Kutentha Kochepa

Ngakhale kuti AH36 imagwira ntchito bwino m'nyengo yocheperako, DH36 ndi EH36 zimagwira ntchito bwino kwambirimikhalidwe ya subzero, kuwapangitsa kukhala abwino kwambiriMa tanki a ku Arctic, nsanja za m'mphepete mwa nyanja, ndi zonyamulira za LNGkumene chitsulo chiyenera kukhala cholimba ngakhale pa -40°C.

3. Kukana Kwambiri Kudzimbiritsa

Kapangidwe ka mankhwala a zitsulo izi, pamodzi ndi zokutira zina kapena chitetezo cha galvanic, zimathandizirakukana dzimbiri la m'nyanja, okosijeni, ndi dzimbiri, kutalikitsa nthawi ya ntchito ya sitimayo.

4. Kutha Kuwotcherera Kwabwino Kwambiri

Magiredi awa amatha kulumikizidwa mosavuta pogwiritsa ntchito njira zodziwika bwino mongaMIG, TIG, ndi kulowetsa arc welding pansi pa madzi (SAW)popanda kutentha pasadakhale. Izi zimatsimikizira kuti zinthu zimapangidwa bwino komanso zimakonzedwa bwino m'malo opangira zombo.

5. Kutopa Kwambiri ndi Kukana Kukhudzidwa

Magalimoto a m'madzi amakhala ndi nthawi yovutikira chifukwa cha mafunde, katundu wolemera, komanso kugwedezeka kwa injini. Zitsulo za AH36, DH36, ndi EH36 zimaperekamphamvu yodabwitsa yotopandikukana kulephera kwa mphamvupansi pa mikhalidwe yobwerezabwereza yokweza.

6. Ubwino Wofanana ndi Kulondola kwa Miyeso

Yopangidwa kudzera mu kukonzedwa koyendetsedwa ndi kuponderezedwa ndi kutentha,sakysteel'sMa plate a AH36, DH36, ndi EH36 amawonetsa makulidwe ofanana, kapangidwe kake ka tirigu wosalala, komanso kusalala kwabwino, zomwe zimapangitsa kuti zigwirizane bwino komanso zigwire bwino ntchito pomanga.

7. Kutsatira Malamulo Okhudza Magulu a Mayiko Osiyanasiyana

Magiredi onse akutsatira zofunikira za:

• Bungwe la Kutumiza la ku America (ABS)

• Kaundula wa Lloyd (LR)

• Det Norske Veritas (DNV)

• Bureau Veritas (BV)

• Bungwe Logawa Magulu la China (CCS)

• Germanischer Lloyd (GL)

Zikalata zimenezi zimatsimikizira kutsatiridwa kwathunthu ndi kudalirika kwa mapulojekiti omanga nyanja padziko lonse lapansi.

Kugwiritsa ntchito Mapepala a Chitsulo a AH36, DH36, ndi EH36

1. Ma Hull ndi Ma Deck Buildings

Mphamvu yochuluka ya AH36 ndi DH36 imawapangitsa kukhala abwino kwambirima shells a sitima, ma bulkheads, ndi magawo a deck, kuonetsetsa kuti kapangidwe kake kali bwino pansi pa madzi ambiri oyenda pansi pa nyanja.

2. Mapulatifomu akunja

Ma plate a EH36 amagwiritsidwa ntchito kwambiri mumalo osungira mafuta m'nyanja, malo osungiramo ndi kutsitsa mafuta oyandama (FPSO), ndi nyumba za pansi pa nyanja, komwe kukana kugwedezeka ndi dzimbiri ndikofunikira.

3. Magalimoto Onyamula Katundu ndi Mafuta

Kutha kupirira dzimbiri ndi kutopa kumatsimikizira kuti mafuta, gasi, ndi mankhwala zimanyamulidwa bwino patali.

4. Zonyamulira za LNG ndi Zombo Zozizira

EH36 ndi yabwino kwambiri pamalo obisika, kusunga kulimba ngakhale kutentha kochepa kwambiri panthawi yosungira ndi kusamutsa LNG.

5. Zombo Zapamadzi ndi Zachitetezo

Kuphatikiza kwa mphamvu zambiri komanso zopepuka kumapangitsa zitsulo izi kukhala zoyenerazombo zoyenda pansi pa madzi, zombo zolondera, ndi zombo zoyenda m'madzi, komwe kuchita bwino ndi kusinthasintha ndizofunikira kwambiri.

6. Zipangizo Zam'madzi ndi Zigawo Zamkati

Kupatula ma hulls, zitsulo 316 ndi DH36 zimagwiritsidwa ntchito muma crane, ma winchi, makina omangirira, ndi nyumba zina, komwe mphamvu ndi kukana dzimbiri ndizofunikira kwambiri.

Kuyesa ndi Chitsimikizo

Kuti muwonetsetse kuti ntchito yabwino kwambiri ikuyenda bwino,sakysteelimachita kuwongolera bwino kwambiri komanso kuyesa pa gulu lililonse la mbale za AH36, DH36, ndi EH36:

• Kuyesa Kwamphamvukuti mupeze phindu ndi mphamvu zomaliza

• Kuyesa kwa Charpy Impactkulimba kotsika kutentha

• Kuyesa kwa Ultrasonic (UT)za zolakwika zamkati

• Kuyang'anira Makulidwe ndi Kuyang'ana Pamwambakuti zikhale zolondola komanso zosalala

• Kusanthula kwa Mankhwala (Spectrometer)kuti zitsimikizidwe kuti zapangidwa bwanji

Zinthu zonse zimaphatikizidwa ndiZikalata Zoyesera za Mill (EN 10204 3.2 kapena 3.1), kupereka kutsata kwathunthu ndikutsatira miyezo yapadziko lonse lapansi.

Chiyembekezo cha M'tsogolo: Zitsulo Zamphamvu Kwambiri Pakupanga Zombo Zamakono

Pamene njira zomangira zombo padziko lonse lapansi zikupita patsogolozombo zogwiritsa ntchito mphamvu zochepa, zopepuka, komanso zosawononga chilengedwe, zitsulo zolimba kwambiri monga AH36, DH36, ndi EH36 zikukhala zofunika kwambiri. Zimalola kumanga zombo zazikulu komanso zosagwiritsa ntchito mafuta ambiri popanda kuwononga mphamvu kapena chitetezo.

Komanso, kukula kwamphamvu ya mphepo ya m'mphepete mwa nyanja ndi kufufuza m'nyanja yakuya, kufunikira kwa zitsulo zamtundu wa EH36 — zomwe zimatha kupirira kutentha kochepa komanso kupsinjika kwa madzi akuya — kukuyembekezeka kuwonjezeka.

Kafukufuku wopitilira muukadaulo wa zitsulo ndi njira zoyendetsera zozungulira zidzawonjezeranso mphamvu za zitsulo zam'madzi, kuonetsetsa kuti zikukwaniritsa zofunikira pakukhazikika komanso magwiridwe antchito mtsogolo.
