Cov Kev Siv Cov Phaj Hlau AH36, DH36, thiab EH36 hauv Kev Tsim Nkoj thiab Cov Haujlwm Offshore

Hauv kev lag luam thoob ntiaj teb hauv dej hiav txwv thiab ntug dej hiav txwv, cov phaj hlau ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ruaj khov, kev nyab xeeb, thiab lub neej ntev ntawm cov nkoj thiab cov platforms ua haujlwm hauv qee qhov chaw nyuaj tshaj plaws hauv ntiaj teb. Ntawm cov ntaub ntawv siv dav tshaj plaws yogCov phaj hlau AH36, DH36, thiab EH36, uas yog cov hlau muaj zog siab hauv qab ASTM A131 cov qauv. Cov qib no tau tsim los kom tiv taus cov khoom hnyav, kev cuam tshuam, thiab cov xwm txheej corrosive hauv dej hiav txwv, ua rau lawv tsis tseem ceeb rau kev tsim nkoj niaj hnub thiab cov haujlwm tsim kho hauv hiav txwv.

At sakyalloy, peb muab cov khoom zoo tshaj plawsCov phaj hlau AH36, DH36, thiab EH36uas ua tau raws li cov qauv thoob ntiaj teb thiab xa cov kev ua tau zoo sib xws thoob plaws ntau yam kev siv uas xav tau.

1. Kev Txheeb Xyuas Txog AH36, DH36, thiab EH36 Cov Qib Hlau

AH36, DH36, thiab EH36 yog cov hlau marine muaj zog heev uas feem ntau siv rau hauv kev tsim cov nkoj thiab cov qauv hauv hiav txwv. Qhov sib txawv tseem ceeb ntawm cov qib no nyob rau hauv lawvkev xav tau ntawm kev cuam tshuamntawm qhov kub sib txawv:

  • AH36Kuaj ntawm 0 ° C (chav tsev kub thiab tawv)

  • DH36Kuaj ntawm -20 ° C (qhov kub qis)

  • EH36Kuaj ntawm -40 ° C (qhov kub tsis tshua muaj zog)

Cov qib no muaj cov tshuaj lom neeg zoo sib xws thiab cov khoom siv kho tshuab, muab kev sib xyaw ua ke zoo tshaj plaws ntawmlub zog tawm los (yam tsawg kawg nkaus 355 MPa)thiablub zog tensile (490–620 MPa), uas ua kom muaj peev xwm thauj khoom siab thiab tiv taus kev hloov pauv.

2. Cov yam ntxwv tshuaj lom neeg thiab tshuab

Cov tshuaj lom neeg sib xyaw ntawm AH36, DH36, thiab EH36 steel phaj feem ntau muaj xws li:

  • Cov pa roj carbon (C):≤ 0.18%

  • Manganese (Mn):0.90–1.60%

  • Silicon (Si):0.10–0.50%

  • Phosphorus (P):≤ 0.035%

  • Sulfur (S):≤ 0.035%

Cov hlau no kuj tseem yuav muaj covcov khoom siv micro-alloyingxws li niobium, vanadium, thiab titanium los txhim kho cov noob nplej kom zoo thiab txhim kho kev tawv.

Cov khoom siv kho tshuab:

  • Lub zog tawm los: ≥ 355 MPa

  • Lub zog tensile: 490–620 MPa

  • Kev Ntev: ≥ 21%

  • Kev Ntsuas Qhov Cuam Tshuam Charpy V-notch: 0 ° C (AH36), -20 ° C (DH36), -40 ° C (EH36)

Qhov kev sib xyaw ua ke zoo tshaj plaws ntawm lub zog thiab kev tawv nqaij ua rau cov qib no tswj tau qhov weldability zoo heev thiab formability thaum lub sijhawm tsim khoom.

3. Cov Ntawv Thov Hauv Kev Lag Luam Nkoj

a. Kev Tsim Lub Hull

Lub hull yog lub hauv paus ntawm txhua lub nkoj, xav tau cov ntaub ntawv uas tuaj yeem tiv taus kev ntxhov siab thiab kev khoov. AH36, DH36, thiab EH36 steel phaj yog siv dav rauplating lub cev nkoj, cov qauv ntawm lub deck, thiabkeel seem.

Cov ntaub ntawv no zoo tagnrho rau:

Lawv lub zog tensile siab ua kom muaj kev ua tau zoo dua nyob rau hauv kev ntxhov siab ntawm cov khoom hnyav thiab cov xwm txheej dej hiav txwv turbulent.

b. Cov Bulkheads thiab Superstructures

Cov phaj DH36 thiab EH36 feem ntau raug xaiv rau cov bulkheads thiab superstructures vim lawv muaj peev xwm tiv taus kev tawg ntawm qhov kub qis, uas yog qhov tseem ceeb tshaj plaws rauKev caij nkoj Arctic or cov nkoj polar-class.

c. Cov Phaj Deck thiab Cov Khoom Siv Txhawb Nqa

Qhov vuam tau zoo heev ntawm cov hlau no ua rau lawv haum rau cov phaj txhawb nqa lub lawj, cov qauv thav duab, thiab lwm yam khoom uas xav tau kev tiv taus kev nkees siab.

4. Cov Ntawv Thov Offshore thiab Zog

Dhau ntawm kev tsim nkoj, AH36, DH36, thiab EH36 cov phaj hlau ua lub luag haujlwm tseem ceeb hauvcov haujlwm tsim kho hauv hiav txwv thiab dej hiav txwv, xws li:

a. Cov Chaw Tsim Roj thiab Roj Av Hauv Dej Hiav Txwv

Cov qib no siv rau hauvcov jack-up rigs, semi-submersible platforms, thiab FPSOs (Floating Production Storage and Offloading units)Lawv lub zog ua haujlwm tau zoo thaum muaj kev cuam tshuam thiab kev tiv thaiv xeb hauv cov dej ntsev ua rau lawv zoo tagnrho rau cov platform decks, ceg, thiab cov nqaj txhawb nqa.

b. Cov Qauv Zog Cua

Nrog rau kev hloov pauv thoob ntiaj teb mus rau lub zog rov ua dua tshiab,cov chaw ua liaj ua teb cua hauv hiav txwvtab tom nthuav dav sai sai. EH36 steel phaj, nrog rau kev ua kom muaj zog dua, feem ntau yog siv rau hauvlub hauv paus ntawm lub pej thuam cua, cov monopiles, thiab cov khoom hloov pauvkom tiv taus nthwv dej siab thiab cua hlob.

c. Cov Khoom Siv Hauv Qab Dej Thiab Cov Kav Dej

Hauv cov ntawv thov subsea, DH36 thiab EH36 qib yog siv rauCov hlab ntsha siab, cov kav dej txhawb nqa, thiab cov qauv tsim hauv qab dej hiav txwv, xyuas kom ruaj khov mus sij hawm ntev tiv thaiv kev qaug zog thiab kev xeb.

5. Kev Tsim Khoom thiab Kev Ua Vuam

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm AH36, DH36, thiab EH36 steel phaj yog lawv covzoo heev weldability thiab workabilityLawv tuaj yeem vuam siv cov txheej txheem xws li:

  • Kev Vuam Hlau Tiv Thaiv (SMAW)

  • Kev Siv Gas Metal Arc Vuam (GMAW)

  • Kev Siv Flux-Cored Arc Vuam (FCAW)

Lawv cov nqi sib npaug ntawm cov pa roj carbon tsawg (CEV) ua kom ntseeg tau tiastsawg kawg nkaus kev pheej hmoo ntawm kev tawgthaum lub sijhawm vuam thiab muaj kev tiv taus siab rau qhov kub-cuam tshuam brittleness. Kev kho cua sov tom qab vuam tsis tshua xav tau, uas ua rau kev tsim khoom sai dua thiab pheej yig dua.

At sakyalloy, txhua lub phaj raug raukev kuaj ultrasonic, kev tshuaj xyuas qhov ntev thiab kev txheeb xyuas cov khoom siv kho tshuabkom ntseeg tau tias ua raws li ASTM, ABS, LR, DNV, thiab BV cov qauv.

6. Kev Tiv Thaiv Kev Xeb thiab Kev Kho Mob Nto

Kev ua haujlwm hauv cov chaw nyob hauv dej hiav txwv ua rau cov qauv hlau raug kev tawm tsam tas li los ntawm dej ntsev, av noo, thiab cov pa phem hauv huab cua. AH36, DH36, thiab EH36 cov hlau ua rau muaj kev tiv thaiv xeb zoo vim yog kev tswj hwm alloying thiab tuaj yeem tiv thaiv ntxiv los ntawm:

  • Kev txhaj tshuaj blasting thiab priming

  • Cov txheej txheem zinc lossis epoxy

  • Cov txheej txheem tiv thaiv cathodic

Cov kev kho saum npoo no ua rau lub neej ua haujlwm ntawm cov nkoj thiab cov chaw ua haujlwm hauv hiav txwv ntev dua, txo cov nqi kho thiab tiv thaiv kev puas tsuaj ntawm cov qauv.

7. Kev Pom Zoo ntawm Lub Koom Haum Kev Faib Tawm
