Mefuta e Tloaelehileng ea Size bakeng sa API 5L X52 Pipe
Pipe ea X52, joalo ka limaraka tse ling ho API 5L, e tla ka boholo bo fapaneng ho lumellana le litlhoko tse fapaneng tsa projeke. Mefuta e tloaelehileng ea boholo ba pipe ea X52 hangata e kenyelletsa:
- Kantle Diameter (OD): 1/2 inch (12.7 mm) ho isa ho 80 inches (2032 mm)
- Botenya ba Lebota: 0.109 inch (2.77 mm) ho isa ho 2 inches (50.8 mm)
- Bolelele: maoto a 20 (limithara tse 6.1) ho isa maotong a 80 (limithara tse 24.4), 'me bolelele ba tsona bo fumaneha ha bo kōptjoa
Ho bohlokoa ho hlokomela hore ha se mefuta eohle e kopaneng ea bophara le botenya ba lebota e fumanehang kapa e sebetsang. Likhetho tse khethehileng tsa boholo li ka fapana ho latela mokhoa oa tlhahiso (ERW kapa LSAW) le ts'ebeliso e reriloeng ea phala.
The versatility ka boholo mefuta e fapaneng lumella Pipe ea X52 e tla sebelisoa liindastering tse fapaneng, ho kenyelletsa phetiso ea oli le khase, kabo ea metsi, le lits'ebetso tsa meralo. Bokhoni ba ho khetha ho tsoa mefuteng e fapaneng ea litekanyo bo thusa baenjiniere ho ntlafatsa khetho ea liphaephe ho latela lintlha tse joalo ka litlhoko tsa khatello, sekhahla sa phallo le lithibelo tsa ho kenya.
Ha u hlakisa phala ea X52 bakeng sa projeke, ho bohlokoa hore u se ke oa nahana ka boholo feela empa hape le lintlha tse ling tse joalo ka phepelo e qetellang (bofelo, beveled kapa khoele), litlhoko tsa ho roala, le litlhoko life kapa life tse ling tsa tlhahlobo kapa setifikeiti [1].
Botenya ba Lerako le Likhetho tsa Diameter bakeng sa ERW le LSAW X52 Pipes
Pipe ea X52 e atisa ho etsoa ka mekhoa e 'meli ea mantlha: Electric Resistance Welding (RW) le Longitudinal Submerged Arc Welding (LSAW). Mokhoa o mong le o mong o na le bokhoni le mefokolo ea ona ha ho tluoa ho botenya ba lebota le likhetho tsa bophara:
Liphaephe tsa ERW X52:
- Diameter Range: Ka tloaelo 1/2 inch (12.7 mm) ho isa ho 24 inches (609.6 mm)
- Botenya ba Lebota: 0.109 inch (2.77 mm) ho isa ho 0.750 inches (19.05 mm)
Liphaephe tsa ERW li tsebahala ka botenya ba tsona bo sa fetoheng ba lebota le ho mamellana ka mokhoa o tiileng. Hangata li ratoa bakeng sa lisebelisoa tse nyenyane tsa bophara le moo ho hlokahalang lihlahisoa tse phahameng.
LSAW X52 Liphaephe:
- Diameter Range: Ka kakaretso lisenthimithara tse 16 (406.4 mm) ho isa ho 80 inches (2032 mm)
- Botenya ba Lebota: 0.250 inch (6.35 mm) ho isa ho 2 inches (50.8 mm)
Liphaephe tsa LSAW li na le li-diameter tse kholoanyane le marako a maholo ha li bapisoa le lipeipi tsa ERW. Hangata li sebelisoa lits'ebetsong tsa khatello e phahameng le mererong ea kantle ho naha moo ho hlokahalang boholo ba liphaephe tse kholoanyane.
Khetho pakeng tsa ERW le LSAW X52 lipeipi e itšetlehile ka lintlha tse fapaneng, ho kenyelletsa:
- Litlhoko tsa projeke (mohlala, likhatello tsa khatello, khanyetso ea kutu)
- Mokhoa oa ho kenya le sebaka
- Litšenyehelo
- Ho fumaneha ha lisebelisoa tsa tlhahiso
Ke habohlokoa ho hlokomela hore tsoelo-pele ea theknoloji ea tlhahiso e entse hore ho be le kamano e itseng ea bokhoni ba mekhoa ea ERW le LSAW, haholo-holo li-diameter tse bohareng. Sena se fana ka likhetho tse ling bakeng sa baenjiniere le batsamaisi ba merero ha ba khetha phala e nepahetseng ka ho fetisisa bakeng sa litlhoko tsa bona tse ikhethang [2].
Boholo bo Ama Khatello le Phallo Joang Liphaepheng tsa X52?
Boholo ba phala ea X52, ho kenyeletsoa bophara le botenya ba lebota, bo bapala karolo ea bohlokoa ho lekanyeng matla a khatello le litšobotsi tsa phallo ea sistimi ea liphaephe. Ho bohlokoa ho utloisisa likamano tsena bakeng sa moralo le ts'ebetso e nepahetseng ea liphaephe:
Matla a Khatello:
Bokhoni ba khatello ea Pipe ea X52 e amana ka kotloloho le botenya ba lebota le bophara ba eona. Kamano e hlalosoa ke hoop stress formula:
P = (2 * S * t) / D
Where:
- P = Khatello ea ka hare
- S = Khatello ea maikutlo e lumelletsoeng (e khethiloeng ke thepa ea tšepe ea X52)
- t = Botenya ba lebota
- D = Bophara ba ka ntle
Ha lerako le ntse le eketseha, matla a khatello ea pipe a eketseha. Ka lehlakoreng le leng, ha bophara bo ntse bo eketseha (ka botenya bo tšoanang ba lerako), matla a khatello a fokotseha. Ke ka lebaka leo lipeipi tse kholoanyane tse bophara ba atisang ho hloka marako a teteaneng ho boloka tekanyo ea khatello e tšoanang le ea liphaephe tse nyenyane.
Litšobotsi tsa Phallo:
Bophara ba phala ea X52 bo ama haholo litšobotsi tsa eona tsa phallo. Kamano e teng lipakeng tsa boholo ba liphaephe le sekhahla sa phallo e hlalosoa ke continuity equation:
Q = V *A
Where:
- Q = Sekhahla sa phallo ea volumetric
- V = Lebelo la metsi
- A = Sebaka sa phallo ea phaephe
Peipi e kholoanyane ea bophara e ka tsamaisa mokelikeli o mongata ka lebelo le tšoanang ha e bapisoa le phala e nyane. Sena se bolela hore bakeng sa lebelo le fanoeng la phallo, liphaephe tse kholoanyane li tla ba le lebelo le tlase la mokelikeli, tse ka bang molemo ho fokotsa khoholeho le tahlehelo ea khatello ka lebaka la khohlano.
Leha ho le joalo, ho bohlokoa ho leka-lekanya melemo ea li-diameter tse kholoanyane le lintlha tse sebetsang tse kang:
- Litšenyehelo tsa thepa
- Mathata a ho kenya
- Litlhoko tsa ho pompa
- Mabelo a fokolang a ho phalla a hlokahalang ho thibela ho bokellana ha sediment
Ho khethoa ha boholo bo nepahetseng ba phala ea X52 bakeng sa kopo e fanoeng ho hloka hore ho nahanoe ka hloko lintlha tsena, hammoho le lipalo tsa hydraulic le tlhahlobo ea moruo. Baenjiniere ba tlameha ho leka-lekanya litlhoko tsa khatello, sekhahla sa phallo se lakatsehang, le katleho ea sistimi ka kakaretso ho fumana boholo bo nepahetseng ba liphaephe.
Moetsi oa Lipeipi tsa X52
52 pipe e fana ka mefuta e mengata ea likhetho tsa boholo, e etsa hore e be khetho e fapaneng bakeng sa lits'ebetso tse fapaneng tsa liphaephe. Ho tloha liphaepheng tse nyenyane tsa ERW ho ea ho liphaephe tse kholo tsa LSAW tse bophara, tšepe ea X52 e ka etsoa ho finyella litlhoko tse fapaneng tsa morero. Ho utloisisa kamano pakeng tsa boholo ba liphaephe, matla a khatello, le litšobotsi tsa phallo ho bohlokoa bakeng sa moralo o nepahetseng oa liphaephe le ts'ebetso.
Ha u khetha pipe bakeng sa morero oa hau, nahana ka lintlha tse kang litekanyetso tsa khatello, litlhoko tsa phallo, lithibelo tsa ho kenya, le litšenyehelo tsa nako e telele tsa ts'ebetso. Ka ho hlahloba lintlha tsena ka hloko, u ka etsa bonnete ba hore tsamaiso ea lipeipi tsa hau e sebetsa hantle le ka botšepehi lilemong tse tlang.
Bakeng sa tataiso ea litsebi mabapi le ho khetha se nepahetseng Pipe ea X52 bakeng sa litlhoko tsa hau tse ikhethileng, nahana ka ho fihlela moetsi ea tsebahalang. Sehlopha sa Longma, e leng e 'ngoe ea baetsi ba liphaephe tsa tšepe tsa ERW/LSAW tse etelletseng pele ho tloha ka 2003, e sebetsa ka ho khetheha tlhahisong ea lipeipi tsa tšepe tse bophara bo boholo, tse teteaneng, tse mahlakoreng a mabeli, a sub-arc-seam welding. Ka tlhahiso ea selemo le selemo e fetang lithane tse 1,000,000 ho tloha ka 2023, Sehlopha sa Longma se na le boiphihlelo le bokhoni ba ho fihlela litlhoko tsa hau tsa lipeipi tse 52.
