Litšebeliso tsa Lipoleiti tsa Tšepe tsa AH36, DH36, le EH36 mererong ea kaho ea likepe le ea kantle ho naha

Liindastering tsa leoatle le tsa leoatle lefatšeng ka bophara, lipoleiti tsa tšepe li phetha karolo ea bohlokoa ho netefatseng botšepehi ba sebopeho, polokeho le bophelo bo bolelele ba likepe le liforomo tse sebetsang libakeng tse ling tse thata ka ho fetisisa Lefatšeng. Har'a thepa e sebelisoang haholo keLipoleiti tsa tšepe tsa AH36, DH36, le EH36, tse leng tsa sehlopha sa tšepe ea meaho e matla haholo tlas'a maemo a ASTM A131. Mekhahlelo ena e entsoe ho mamella meroalo e feteletseng, litšusumetso le maemo a senyang a leoatle, e leng se etsang hore e be ea bohlokoa bakeng sa merero ea sejoale-joale ea kaho ea likepe le ea boenjiniere ba leoatleng.

At sakyalloy, re fana ka boleng bo holimoLipoleiti tsa tšepe tsa AH36, DH36, le EH36tse fihlelang maemo a machaba le tse fanang ka tshebetso e tsitsitseng ho pholletsa le dikopo tse fapaneng tse hlokang boiteko.

1. Kakaretso ea Mekhahlelo ea Tšepe ea AH36, DH36, le EH36

AH36, DH36, le EH36 ke litšepe tsa leoatleng tse matla haholo tse sebelisoang haholo-holo kahong ea likepe le meaho e lebōpong la leoatle. Phapang e kholo lipakeng tsa maemo ana e ho tsonalitlhoko tsa ho ba le matla a tšusumetsomochesong o fapaneng:

  • AH36: E lekiloe ho 0°C (ho tiea ha mocheso oa kamore)

  • DH36: E lekiloe ho -20°C (ho tiea ha mocheso o tlase)

  • EH36: E lekiloe ho -40°C (ho tiea ho feteletseng mochesong o tlase)

Lihlopha tsena li na le sebopeho se tšoanang sa lik'hemik'hale le thepa ea mechini, e leng se fanang ka motsoako o motle oamatla a tlhahiso (bonyane 355 MPa)lematla a ho thapolla (490–620 MPa), e netefatsang bokgoni bo phahameng ba ho jara mojaro le ho hanyetsa ho fetoha ha sebopeho.

2. Litšobotsi tsa Lik'hemik'hale le Mekaniki

Sebopeho sa lik'hemik'hale sa lipoleiti tsa tšepe tsa AH36, DH36, le EH36 hangata se kenyelletsa:

  • Khabone (C):≤ 0.18%

  • Manganese (Mn):0.90–1.60%

  • Silicone (Si):0.10–0.50%

  • Fosforase (P):≤ 0.035%

  • Sebabole (S):≤ 0.035%

Litšepe tsena li ka boela tsa ba lelikarolo tse kopanyang tse nyanetse kang niobium, vanadium, le titanium ho ntlafatsa ntlafatso ea lijo-thollo le ho matlafatsa ho tiea.

Thepa ea mechini:

  • Matla a ho hlahisa: ≥ 355 MPa

  • Matla a ho Thanya: 490–620 MPa

  • Ho lelefatsa: ≥ 21%

  • Teko ea Tšusumetso ea Charpy V-notch: 0°C (AH36), -20°C (DH36), -40°C (EH36)

Motsoako ona o motle oa matla le ho tiea o lumella limaraka tsena ho boloka ho tjheseletsa le ho bopeha hantle nakong ea tlhahiso.

3. Likopo Indastering ea Kaho ea Likepe

a. Kaho ea Likepe

Mmele ke mokokotlo oa sekepe sefe kapa sefe, o hloka thepa e ka mamellang khatello ea khatello le ho kobeha. Lipoleiti tsa tšepe tsa AH36, DH36, le EH36 li sebelisoa haholo bakeng saho penta ha khetla, meaho ea mathulelelikarolo tsa keel.

Lisebelisoa tsena li loketse:

  • Likepe tsa likhonteinara le likepe tsa thepa

  • Likepe tsa oli le likepe tsa LNG

  • Likepe tsa sesole sa metsing le tsa paterole

  • Likepe tsa bapalami le tsa maeto a sekepe

Matla a tsona a ho thapolla a tiisa tshebetso e ntle haholo tlasa kgatello ya meroalo e boima le maemo a lewatle a moferefere.

b. Lihlooho tse kholo le Meaho e Meholo

Lipoleiti tsa DH36 le EH36 hangata li khethoa bakeng sa li-bulkhead le li-superstructure ka lebaka la bokhoni ba tsona ba ho hanela ho robeha ha bonolo mochesong o tlase, e leng ntho ea bohlokoa haholo bakeng saHo tsamaea ka sekepe sa Arctic or likepe tsa sehlopha sa polar.

c. Lipoleiti tsa Deck le Matlafatso

Ho kgona ho tjheseletsa hantle ha ditshipi tsena ho etsa hore di lokele dipoleiti tsa matlafatso ya di-deck, meaho ya foreimi, le dikarolo tse ding tse jarang mojaro tse hlokang ho hanelwa ke mokhathala o phahameng.

4. Dikopo tsa Mabopong a Leoatle le tsa Matla

Ka nqane ho kaho ya dikepe, dipoleiti tsa tshepe tsa AH36, DH36, le EH36 di bapala karolo e kgolo homerero ea boenjiniere ba leoatleng le metsing, joalo ka:

a. Liforomo tsa Oli le Khase tse Seleteng sa Marang-rang

Lihlopha tsena li sebelisoa holi-rig tsa jack-up, li-platform tse ka qoelisoang ka halofo, le li-FPSO (Li-unit tsa Polokelo ea Tlhahiso e Phaphametseng le tsa ho Laolla). Ho mamella ha tsona tlas'a tšusumetso le ho hanyetsa mafome libakeng tsa metsi a letsoai ho li etsa hore li be ntle bakeng sa li-platform decks, maoto le libalaka tsa tšehetso.

b. Dibopeho tsa Matla a Moya

Ka phetoho ea lefats'e ho ea ho eneji e nchafatsoang,mapolasi a moea a lebopong la leoatleli atoloha ka potlako. Lipoleiti tsa tšepe tsa EH36, tse nang le matla a phahameng, li sebelisoa hangata hometheo ea tora ea moea, li-monopile, le likotoana tsa phetohoho mamella maqhubu a phahameng le meroalo ea moea.

c. Lisebelisoa tsa Ka tlas'a Leoatle le Liphaephe

Litšebelisong tsa ka tlas'a leoatle, limaraka tsa DH36 le EH36 li sebelisoa bakeng salijana tsa khatello, litšehetso tsa liphaephe, le liforeimi tsa meaho tse ka tlas'a leoatle, ho netefatsa hore e tšoarella nako e telele khahlanong le mokhathala le mafome.

5. Tshebetso ea Tlhahiso le ho Welding

E 'ngoe ea melemo ea bohlokoa ea lipoleiti tsa tšepe tsa AH36, DH36, le EH36 ke hore li na leho tjheseletsa hantle le ho sebetsa hantleLi ka kopanngoa ka ho sebelisa mekhoa e tloaelehileng e kang:

  • Ho Welding ka Tšepe e Sirelelitsoeng (SMAW)

  • Ho Wellisa Tšepe ea Khase (GMAW)

  • Ho Welding ha Arc e nang le Di-Flux-Cored (FCAW)

Boleng ba tsona bo lekanang le khabone e tlase (CEV) bo netefatsakotsi e fokolang ea ho petsohaNakong ea ho tjheseletsa le ho hanyetsa ho hoholo ho robehang ha sebaka se amehileng ke mocheso. Kalafo ea mocheso ka mor'a ho tjheseletsa ha e hlokehe hangata, e leng se etsang hore tlhahiso e be kapele le e theko e tlaase.

At sakyalloy, lipoleiti tsohle li kenngoa tlas'atlhahlobo ea ultrasound, tlhahlobo ea litekanyo, le netefatso ea thepa ea mechiniho netefatsa hore ho latela maemo a ASTM, ABS, LR, DNV, le BV.

6. Ho Hanela Tshenyo le Kalafo ya Bokaholimo

Ho sebetsa libakeng tsa leoatle ho pepesetsa meaho ea tšepe tlhaselo e sa khaotseng e tsoang metsing a letsoai, mongobo le litšila tse silafatsang sepakapakeng. Litšepe tsa AH36, DH36, le EH36 li bontša khanyetso e ntle ea mafome ka lebaka la ho kopanngoa ho laoloang 'me li ka sireletsoa haholoanyane ka:

  • Ho phatloha le ho tjhesa dithunya

  • Liaparo tsa zinki kapa epoxy

  • Mekhoa ea tšireletso ea cathodic

Litlhare tsena tsa bokaholimo li atolosa bophelo ba tšebeletso ea likepe le liforomo tsa leoatleng, li fokotsa litšenyehelo tsa tlhokomelo le ho thibela ho senyeha ha sebopeho.

7. Ditumello tsa Mokgatlo wa Tlhophiso

Lipoleiti tsa tšepe tsa AH36, DH36, le EH36 li amoheloa ke mekhatlo e meholo ea lihlopha lefatšeng ka bophara, ho kenyeletsoa:

  • ABS (Lefapha la Amerika la ho Romela Likepe)

  • LR (Rejistara ea Lloyd)

  • BV (Ofisi ea Veritas)

  • DNV (Det Norske Veritas)

  • GL, RINA, le NK

Litifikeiti tse joalo li tiisa hore lipoleiti li fihlela litekanyetso tse tiileng tsa boleng le ts'ebetso tse hlokahalang bakeng sa meaho ea bohlokoa ea likepe le mabopong a leoatle.

8. Melemo ea ho Sebelisa AH36, DH36, le EH36

  • Karolelano e phahameng ea matla ho ea boimae fokotsa boima ba sekepe ka kakaretso, e ntlafatsa ts'ebeliso e ntle ea mafura.

  • Ho tjheseletsa hantle haholoe nolofatsa mekhoa ea tlhahiso le tokiso.

  • Khanyetso e phahameng ea tšusumetsoe netefatsa polokeho le ts'ebetso esita le maemong a batang haholo.

  • Boleng bo netefalitsoeng le bo ka latelwange loketse maemo a machaba a ho arola likepe.

  • Tharollo e theko e tlaaseha e bapisoa le litšepe tsa alloy bakeng sa maemo a ts'ebetso a tšoanang.

9. Bareki ba Tloaelehileng le Basebelisi ba ho Qetela

Liindasteri tse itšetlehileng haholo ka lipoleiti tsa AH36, DH36, le EH36 li kenyelletsa:

  • Libaka tsa likepe le baetsi ba likepe

  • Likhamphani tsa boenjiniere ba oli le khase

  • Bahlahisi ba matla a tsosolositsoeng ba kantle ho naha

  • Borakonteraka ba tšireletso ea likepe tsa metsing

  • Lithupelo tse boima tsa tlhahiso

Lisebelisoa tsena li sebelisitsoe ka katleho mererong ho pholletsa le Asia, Europe, Bochabela bo Hare le Amerika.

10. Hobaneng Khetha sakysteel bakeng sa Litharollo tsa Tšepe ea Marine

sakysteel(karolo easakysteel) e fana ka mefuta e felletseng ea litšepe tsa kaho ea likepe, ho kenyeletsoa AH36, DH36, le EH36, tse tsoang liindastering tse tsebahalang 'me li fumaneha ka litekanyo, botenya le maemo a bokaholimo a ikhethileng.

Melemo ea rona e kenyelletsa:

  • Ho fumaneha ka botlalo ka setifikeiti sa EN 10204 3.2

  • Ho fana ka thepa ka nako le tšehetso ea lefats'e ka bophara ea thepa

  • Litheko tse hlōlisanang bakeng sa liodara tse ngata le tse thehiloeng morerong

  • Tšehetso ea botekgeniki ea litsebi le tšebeletso ea kamora thekiso

Ebang o haha ​​sekepe se secha kapa o etsa liforomo tsa leoatleng,sakysteele netefatsa hore o fumana tšepe ea boleng ba leoatle e fihlelang kapa e fetang litlhoko tsa hau tsa boenjiniere.
