Lipotso Tse Botsoang Khafetsa (Lipotso Tse Botsoang Khafetsa) - Pipe ea Tšepe ea API 5L X65 SSAW
P: Phapang ke efe pakeng tsa API 5L X65 PSL1 le PSL2?
K: PSL2 e na le meeli e thata ea sebopeho sa lik'hemik'hale (C, P, S e tlase), litlhoko tsa ho tiea ha tšusumetso e tlamang (27J @ 0°C), meeli e phahameng ka ho fetisisa ea ho tiea (max 200 HV bakeng sa tšebeletso ea bolila), le liteko tse thata haholoanyane tse sa senyeheng. PSL1 e loketse lits'ebetso tse tloaelehileng tsa liphaephe ntle le litlhoko tsa ts'ebeletso ea mocheso o tlase kapa bolila. PSL2 e khothaletsoa bakeng sa lits'ebetso tsa mose ho maoatle, ts'ebeletso ea bolila, le lits'ebetso tsa mocheso o tlase.
P: Phapang ke efe pakeng tsa X65 le X52?
A: X65 e na le matla a fokolang a tlhahiso a 450 MPa, ha X52 e na le 360 MPa. X65 e fana ka matla a ka bang 25% a hodimo, e leng se dumellang mabota a masesaane, boima bo fokotsehileng, le kgatello e hodimo ya tshebetso. X65 e boetse e na le meedi e thata ya sebopeho sa dikhemikhale bakeng sa ho tiya ho betere le bokgoni ba tshebeletso e bolila.
P: Na API 5L X65 e loketse tšebeletso e bolila?
K: E, API 5L X65 PSL2 e nang le teko e eketsehileng ea HIC (Hydrogen Induced Cracking) le SSC (Sulfide Stress Cracking) e loketse lits'ebetso tsa ts'ebeletso ea sour. Ho thatafala ho laoloa ho fihlela ho 200 HV e phahameng, 'me meeli e itseng ea sebopeho sa lik'hemik'hale ea sebetsa. Ka kopo hlalosa litlhoko tsa ts'ebeletso ea sour mohatong oa khotheishene.
P: Phaephe ea SSAW e bophara bo phahameng ka ho fetisisa eo u ka e hlahisang ka X65 ke efe?
K: Re ka hlahisa phaephe ea X65 SSAW e fihlang ho 3,500mm (li-inchi tse 138) ka ntle. Bakeng sa bophara bo fihlang ho 4,000mm (li-inchi tse 160), ka kopo ikopanye le rona bakeng sa tlhahlobo e khethehileng ea bokhoni ba projeke.
P: Ke dikgetho dife tsa ho roala tse fumanehang bakeng sa phaephe ya mola wa X65?
K: Re fana ka FBE (Fusion Bonded Epoxy), 3LPE (Three Layer Polyethylene), 3LPP (Three Layer Polypropylene), Coal Tar Epoxy, le Liquid Epoxy. Bakeng sa lits'ebetso tsa litšebeletso tsa kantle ho naha le tse bolila, ho khothaletsoa ho roala ka 3LPE kapa FBE.
P: Na o ka fana ka phaephe ya X65 ka tlhahlobo ya motho wa boraro (SGS, BV, TÜV, DNV)?
K: E. Re thusa ho etsa ditlhahlobo ke SGS, BV, TÜV, DNV, ABS, LR, kapa moemedi ofe kapa ofe ya kgethilweng ke moreki nakong ya tlhahiso le pele ho thomello. 3.2 Disetifikeiti tsa tlhahlobo di fanwa ka mehla ha ho kopuwa.
P: Ke teko efe e sa senyeheng (NDT) e fanoang bakeng sa phaephe ea X65 SSAW?
A: NDT e tloaelehileng e kenyelletsa Teko ea Ultrasonic ea 100% (UT) ea 'mele oa weld seam le phaephe, Teko ea Radiographic (RT) ea sebaka, le liteko tsa hydrostatic tse tlamang ka API 5L. Bakeng sa PSL2 le tšebeletso ea sour, ho etsoa UT le MPI e eketsehileng.
P: Nako e tloaelehileng ea ho etella pele bakeng sa phaephe ea tšepe ea API 5L X65 SSAW ke efe?
K: Linako tse tloaelehileng tsa ho etella pele ke matsatsi a ka bang 45-60 bakeng sa tlhahiso ea SSAW, ho latela bongata ba odara, bophara, botenya ba lebota, le litlhoko tsa PSL. Liodara tse potlakileng (matsatsi a 30-45) li ka fumaneha bakeng sa bongata bo bonyenyane.
P: Ke litokomane life tse fanoang ka thomello ka 'ngoe?
A: Setifikeiti sa Teko ea Mill (EN 10204 Mofuta oa 3.1 kapa 3.2), Tlaleho ea Teko ea Hydrostatic, Tlaleho ea Tlhahlobo ea Dimensional, Litlaleho tsa UT, Litlaleho tsa RT (haeba ho boletsoe), Litokomane tsa ho Latela, Lethathamo la ho Paka, Invoice ea Khoebo, le Setifikeiti sa Tšimoloho. Bakeng sa PSL2, litlaleho tsa liteko tsa tšusumetso le litlaleho tsa liteko tsa boima lia kenyelletsoa.
