Tlhahlobo ea Lintho

1. Pipe ea tšepe ea carbon

Pipe ea tšepe ea carbon ke e 'ngoe ea lisebelisoa tse sebelisoang haholo bakeng saOli lipeipi tsa tšepe. Haholo-holo e entsoe ka tšepe le carbon, e nang le manganese e nyenyane, silicon, sebabole le phosphorus. Likahare tsa carbon li etsa qeto ea matla le ho tiea ha tšepe. Ka kakaretso, litaba tsa khabone e phahameng li eketsa matla a tšepe, empa ho tiea le ho cheseha lia fokotseha. Ka indasteri ea oli, carbon steel pipe e fana ka tshebetso e babatsehang ka kakaretso. Ha e na matla a holimo feela a ho mamella likhatello tsa lipalangoang tsa oli le khase, empa hape e na le boima bo itseng ba ho ikamahanya le maemo a thata a jeoloji. Ho feta moo, pipe ea carbon steel e batla e le theko e tlaase 'me e fana ka litšenyehelo tse phahameng, e leng se etsang hore e sebelisoe haholo liphaepheng tsa oli le khase.

2. API 5L Steel Pipe Series Materials

Pipe ea tšepe ea API 5L e entsoe ho latela maemo a API 5L a thehiloeng ke American Petroleum Institute (API) 'me e sebelisoa haholo-holo bakeng sa lipeipi tsa oli le khase. Letoto lena la liphaephe tsa tšepe li arotsoe ka lihlopha tse fapaneng ho latela matla a tšepe, joalo ka X52, X60, le X70. Ka mohlala, API 5L X52 Pipe e entsoe ka tšepe e tlaase ea alloy e matla haholo. Ho phaella linthong tsa motheo tse kang k’habone le tšepe, e boetse e na le metsoako ea motsoako e kang niobium, vanadium le titanium. Ho eketsoa ha likarolo tsena tsa alloying ho matlafatsa matla le ho tiea ha tšepe, ha e ntse e ntlafatsa ts'ebetso ea eona ea ho cheseha le ho hanyetsa ho bola. Thepa ea Api 5l X60 Pipe le Api 5l X70 Pipe e ntlafatsoa ho latela motheo ona. Ka ho lokisa karo-karolelano ea likarolo tsa alloying le ts'ebetso ea ho phekola mocheso, matla a tšepe le ts'ebetso e akaretsang li ntlafatsoa le ho feta, e leng ho li nolofalletsang ho fihlela litlhoko tsa lipalangoang tsa oli le khase tlas'a khatello e phahameng le maemo a thata a ts'ebetso.

3. Pipe ea tšepe e se nang Seam

Pipe ea tšepe e se nang seamless e etsoa ka lits'ebetso tse kang perforation le pipe rolling. Thepa ea eona e hlile e ts'oana le phala ea tšepe ea carbon e boletsoeng ka holimo le phala ea tšepe ea Api 5l, empa mofuta o ikhethang oa ts'ebetso ea eona ea tlhahiso e e fa melemo e ikhethang. Pipe ea tšepe e se nang seamless ha e na li-welds leboteng la eona, e leng se etsang hore ho be le sebopeho se akaretsang sa junifomo le matla a phahameng. E khona ho mamella likhatello tse phahameng le maemo a thata a tikoloho. Ka hona, hangata e sebelisoa indastering ea oli bakeng sa lits'ebetso tse hlokang ts'ebetso e phahameng, joalo ka liphaephe tse phahameng tsa khatello ea oli le khase le li-wellheads.

Thepa le Litšobotsi

1. Matla

Matla ke thepa ea bohlokoa ea lipeipi tsa oli, tse amang polokeho ea tsona ka kotloloho nakong ea lipalangoang tsa oli le khase. Matla a matla a liphaephe tsa tšepe tsa API 5l a bontšoa ke nomoro e latelang "X." Ka mohlala, X52 e bontša matla a bonyane a 52 ksi (lik'hilograma ka sekwere-inch), e lekanang le hoo e ka bang 360 MPa ka megapascals; X60 e na le bonyane ba tlhahiso ea matla a 60 ksi (hoo e ka bang 414 MPa); mme X70 e na le matla a fokolang a tlhahiso a 70 ksi (hoo e ka bang 483 MPa). Ha boemo ba matla bo ntse bo eketseha, khatello eo pipe e ka e mamellang e eketseha ka tsela e nepahetseng, e leng se etsang hore e tšoanele liphaephe tsa oli le khase tse nang le litlhoko tse sa tšoaneng tsa khatello. Pipe ea tšepe e sa tsitsang, ka lebaka la sebopeho sa eona se ts'oanang le kabo ea matla e tsitsitseng, e sebetsa hantle ha e mamella likhatello tse phahameng.

2. Corrosion Resistance

Lipalangoang tsa oli le khase ea tlhaho li ka ba le mecha ea litaba e senyang joalo ka hydrogen sulfide le carbon dioxide, kahoo liphaephe tsa oli li tlameha ho ba le boemo bo itseng ba ho hanyetsa ho bola. Pipe ea tšepe ea carbon ka tlhaho e na le khanyetso e fokolang ea kutu, empa khanyetso ea eona ea kutu e ka ntlafatsoa haholo ka ho eketsa likarolo tsa alloying (joalo ka chromium le molybdenum lethathamong la Api 5l) le ho sebelisa litlhare tse thibelang kutu (joalo ka liphahlo le plating). Ka moralo le ts'ebetso e nepahetseng ea thepa, Api 5l X70 Pipe, X60 Pipe, le X52 Pipe, har'a tse ling, li boloka bophelo bo bolelele ba ts'ebeletso libakeng tse senyang.

3. Weldability

Nakong ea kaho ea lipeipi tsa oli, lipeipi tsa tšepe li tlameha ho hokeloa ka tjheseletso, ho etsa hore ho cheseha e be tšobotsi ea bohlokoa ea phala ea tšepe ea peipi ea oli. Pipe ea tšepe ea Api 5l e etselitsoe ka ho khetheha bakeng sa ho chesehela hantle, ho netefatsa matla le ho tiea ha manonyeletso a cheselitsoeng. Li-welds tsa boleng bo holimo le tsona li ka finyelloa ka phala ea tšepe ea carbon le phala ea tšepe e se nang seam ho sebelisa mekhoa e nepahetseng ea ho tjheseletsa.

1. Kantle Diameter

Lipeipi tsa tšepe tsa lipeipi tsa oli li tla ka bophara bo fapaneng ba bophara ba kantle ho fihlela litlhoko tse fapaneng tsa lipalangoang. Mefuta e tloaelehileng ea bophara ba ka ntle bakeng sa liphaephe tsa tšepe tsa Api 5L li kenyelletsa 114.3mm (4 lisenthimithara), 168.3mm (6.625 lisenthimithara), 219.1mm (8.625 lisenthimithara), 273.1mm (10.75 lisenthimithara), 323.9mm (12.75 lisenthimithara), 35mm (41.6 lisenthimithara) 4. lisenthimithara tse 457.2, 457.2 limilimithara (18 inches), 508mm (20 inches), 559mm (22 inches), le 610mm (24 inches). Bophahamo ba kantle ba liphaephe tsa tšepe tse se nang seam bo tšoana le tsa letoto la Api 5L, empa boholo bo sa tloaelehang le bona bo ka hlahisoa ho fihlela litlhoko tsa bareki.

2. Botenya ba Lerako

Botenya ba marako ke ntlha ea bohlokoa e amang matla le matla a ho jara liphaephe tsa tšepe. Botenya ba lerako la liphaephe tsa tšepe tsa petroleum bo fapana ho latela tekanyo ea khatello le litlhoko tsa kopo. Ho nka API 5L X52 pipe e le mohlala, bakeng sa bophara bo ka ntle ba 114.3mm, botenya bo tloaelehileng ba marako bo kenyelletsa 4.0mm, 4.5mm, le 5.0mm. Bakeng sa bophara bo ka ntle ba 219.1mm, botenya ba lebota bo ka ba 6.0mm, 7.0mm, kapa 8.0mm. Liphaephe tsa API 5L X60 le X70, ka lebaka la litlhoko tsa tsona tse phahameng tsa matla, hangata li na le mabota a teteaneng ho feta liphaephe tsa X52 tsa bophara bo tšoanang ba kantle ho netefatsa matla le polokeho e lekaneng. Botenya ba lerako la phala ea tšepe e se nang moeli bo ka laoloa ka nepo ho latela lits'ebetso tsa tlhahiso le litlhoko tsa bareki, ho tloha ho 2mm ho isa ho limilimithara tse mashome a 'maloa.

3. Bolelele

Bolelele bo tloaelehileng ba phala ea tšepe ea petroleum hangata ke limithara tse 6, limithara tse 12, joalo-joalo, bakeng sa boiketlo ba lipalangoang le kaho. Likopong tsa 'nete, bolelele ba tloaelo bo ka boela ba hlahisoa ho latela litlhoko tse khethehileng tsa morero oa liphaephe, ho fokotsa mosebetsi oa ho itšeha le oa welding le ho ntlafatsa katleho ea kaho.

Ka kakaretso, thepa, thepa, le litekanyo tse tloaelehileng tsaOli liphaephe tsa tšepe ke lintlha tsa bohlokoa moralong oa tsona le tšebelisong ea tsona. Pipe ea tšepe ea Carbon, Pipe ea tšepe e se nang Mokotla, le lipeipi tsa tšepe ka har'aPipe ea tšepe ea Api 5lletoto la lihlooho tse, tse kang X70, X60, 'me X52, mong le e mong phetha karolo ea bohlokoa likarolong tse sa tšoaneng tsaOli indasteri ka lebaka la melemo ea bona e ikhethang. Ka tsoelopele e tsoelang pele eaOli indasteri, litlhoko tsa tshebetso le boleng baOli liphaephe tsa tšepe li ntse li e-ba thata haholoanyane.
