X60 Line Pipe, Mechanical Properties Of

X60 Line Pipe, kalafo ea mocheso o holim'a metsi e arotsoe ka mekhahlelo e 'meli, e' ngoe ke kalafo ea mocheso oa lik'hemik'hale, e 'ngoe ke ho tima holim'a metsi le kalafo e futhumatsang ea mocheso, mokhoa oa teko ea boima ke o latelang:

[1] Phekolo ea mocheso oa lik'hemik'hale oa pipeline ea X60
- Kalafo ea mocheso oa lik'hemik'hale ke ho etsa hore bokaholimo ba liphaephe tsa X60 li kenelle athomo e le 'ngoe kapa tse' maloa tsa metsoako ea lik'hemik'hale, e le ho fetola sebopeho sa lik'hemik'hale, sebopeho le thepa ea bokaholimo ba liphaephe tsa X60.Kamora ho tima le mocheso o tlase oa mocheso, bokaholimo ba phaephe ea X60 bo na le boima bo phahameng, ho hanyetsa le ho kopana le matla a mokhathala, 'me motheo oa pipeline ea X60 o na le matla a phahameng le ho tiea.

-- Mekhahlelo ea mantlha ea tekheniki ea kalafo ea mocheso oa lik'hemik'hale X60 ke botebo ba lera le thata le ho thatafala ha bokaholimo.Botebo ba lera le thata bo lokela ho lekoa ke vickers hardness tester.Lekanya sebaka ho tloha holim'a pipe ea X60 ho ea moo boima bo theohelang ho 50HRC.Bona ke botebo bo sebetsang ba ho thatafatsa kalafo ea mocheso oa lik'hemik'hale oa tlhahlobo ea boima ba liphaephe tsa X60 le kalafo e thatafatsang ea mocheso holim'a ho thatafala ha X60 pipeline sensor, e ka sebelisa vickers hardness tester, surface rockwell hardness tester kapa rockwell hardness tester ho etsa liteko, feela botenya ba nitriding e teteaneng e tšesaane, hangata e seng ho feta 0.7 mm, ebe ha e sa khona ho sebelisa tester ea thata ea rockwell, tester ea Microhardness e ka sebelisoa.

[2] X60 phaephe holim'a quenching le ho tempering mocheso kalafo
- Phekolo ea ho tima le ho futhumatsa mocheso hangata e etsoa ka ho futhumatsa ka induction kapa ho futhumatsa lelakabe.Mekhahlelo ea mantlha ea tekheniki ke boima ba bokaholimo, boima ba lehae le botebo bo sebetsang ba ho thatafatsa.Vickers hardness tester e ka sebelisoa bakeng sa tlhahlobo ea boima ba 'mele, rockwell kapa surface Rockwell hardness tester.Khetho ea matla a teko (sekala) e amana le botebo ba lera le thatafatsang le boima ba holim'a liphaephe tsa X60.Ho na le mefuta e meraro ea boima ba limithara tse amehang.

Vickers hardness tester ke mokhoa oa bohlokoa oa ho lekola boima ba bokaholimo ba pipeline ea X60 e tšoaroang mocheso.E ka sebelisa matla a teko a 0.5 ~ 100kg ho lekola bokaholimo bo thata joalo ka 0.05mm.Ho nepahala ha eona ke ho phahameng ka ho fetisisa, 'me e ka khetholla phapang e fokolang ea boima ba holim'a mocheso o tšoaroang ka phala ea X60.Ho phaella moo, botebo ba lera atlehang thatafatsa e boetse e lekanyetsoa ka vickers hardness tester, kahoo ho ke ke ho hlokahala hore ho hlomella Vickers hardness tester bakeng sa diyuniti phetha holim'a mocheso kalafo kapa sebelisa palo e kholo ea holim'a mocheso kalafo workpiece.

- Surface Rockwell hardness tester e boetse e loketse haholo bakeng sa ho lekola boima ba phala e thata ea lipeipi tsa X60.Ho na le litekanyo tse tharo tsa "Rockwell hardness tester" tseo u ka khethang ho tsona.E ka leka mefuta e fapaneng ea mela e thata ea X60 ka botebo bo thata ho feta 0.1mm.Le hoja ho nepahala ha sefahleho sa Rockwell hardness tester ha se hodimo ho feta vickers hardness tester, se ka kopana le ditlhoko e le mokgwa wa teko bakeng sa taolo ya boleng le ho hlahloba ho dumellana ha dimela tsa kalafo ya mocheso.Ho feta moo, e boetse e na le litšobotsi tsa tshebetso e bonolo, tšebeliso e bonolo, theko e tlaase, tekanyo e potlakileng, 'me e ka bala ka ho toba boleng ba boima, joalo-joalo Surface Rockwell hardness tester e ka sebelisoa bakeng sa batch ea mocheso holim'a mocheso oa X60 pipeline pipeline ka potlako le e seng ea teko e senyang.Sena se bohlokoa haholo bakeng sa ho lokisa lipeipi tsa X60 le lifeme tsa ho etsa mechine.

- Rockwell hardness tester e ka boela ea sebelisoa ha lera le thatafatsang le le letenya.Ha botenya ba lera le thata la kalafo ea mocheso ke 0.4 ~ 0.8mm, sekala sa HRA se ka sebelisoa, ha botenya ba lesela le thata le feta 0.8mm, sekala sa HRC se ka sebelisoa.

- Litekanyetso tsa boima ba Vickers, Rockwell le Surface Rockwell li ka fetoloa habonolo hore e be litekanyetso tse tloaelehileng, tsa ho taka kapa tse hlokoang ke mosebelisi.Litafole tsa phetoho tse tsamaellanang li fanoe ka litekanyetso tsa machaba tsa ISO, ASTM e tloaelehileng ea Amerika le ea China GB/T e tloaelehileng.

[3] Phekolo ea mocheso ea sebakeng seo
- Haeba ho thatafala ha likarolo tsa sebaka seo ho hlokahalang ho ba holimo, phekolo ea mocheso ea sebakeng sa heno e ka etsoa ka ho futhumala ha induction le mekhoa e meng.Liphaephe tse joalo tsa liphaephe tsa X60 hangata li hloka ho tšoaea sebaka sa kalafo ea mocheso e timang sebakeng sa heno le boleng ba bothata ba sebaka sa setšoantšo.Teko ea boima ba pipe ea X60 e tla etsoa sebakeng se khethiloeng.Sesebelisoa sa ho hlahloba boima ba 'mele se ka sebelisa Rockwell hardness tester, teko ea boleng ba boima ba HRC, joalo ka mocheso o thatafatsang mocheso ha o sa teba, o ka sebelisa top Rockwell hardness tester, tlhahlobo ea boima ba HRN.
