Muzviitiko zvemafekitori, migodhi, kana kutapurirana kwemagetsi, kune mhando yemapaipi "asingazivikanwe" gore rese asi ane mabasa akakura - anowanzo takura zvinhu zvine hunhu hwakasimba hwekukwesha senge jecha, slurry, upfu hwemarasha, nezvimwewo. Mapaipi akajairwa anogona kupedzwa munguva pfupi, izvo zvinokanganisa mashandiro ekugadzira chete asiwo zvinoisa njodzi kuchengetedzeka.mapaipi anodzivirira kusakara esilicon carbidendiyo chaiyo yekugadzirisa dambudziko iri remaindasitiri, ichiva muchengeti we "hard core" munzvimbo dzakaoma dzekufambisa.
Chii chinonzi silicon carbide wear pipeline?
Zvichitaurwa zviri nyore, mapaipi asingatsvedzeri silicon carbide mapaipi ekutakura akagadzirwa nekubatanidza silicon carbide sechinhu chikuru chinodzivirira kutsvedza nemapaipi esimbi (akadai semapaipi esimbi) kuburikidza nemaitiro akakosha.
Mumwe munhu angabvunza kuti, chii chinonzi silicon carbide? Chinhu chisina kugadzirwa nesimbi chisina kugadzirwa chakagadzirwa nemaoko chine kuoma kwakanyanya, chiri chechipiri kune dhaimani. Mapepa ejecha nemavhiri ekukuya atinoona muhupenyu hwezuva nezuva zvakagadzirwa nesilicon carbide. Kushandisa 'nyanzvi isingapfeki' yakadaro kugadzira mukati memapaipi kunogona kuvapa simba rakasimba rekupfekwa.
Zvichienzaniswa nemapombi esimbi echinyakare nemapombi ematombo akaumbwa, mukana mukuru wemapombi asingatsvedzeri silicon carbide uri mu "kugadzirisa mukati nekunze": silicon carbide layer yemukati ndiyo inodzivirira kuputsika nekusakara kwechinhu chiri mukati, nepo simbi yekunze ichivimbisa simba rese uye simba rekudzvanya kwepombi. Kubatanidzwa kwezviviri izvi hakungogadzirisi dambudziko rekusakura chete, asiwo kunotarisa kuchengetedzeka nekuvimbika kwekushandiswa mumaindasitiri.
Sei ichigona 'kutsungirira' mamiriro ezvinhu akaomarara?
Kugara kwenguva refu kwemapaipi anodzivirira kupfeka esilicon carbide kunonyanya kubva muhunhu hwezvinhu zvesilicon carbide pachazvo:
Kusapfeka kwakasimba kwazvo: Sezvambotaurwa, silicon carbide ine kuomarara kwakanyanya, uye kupfeka kwayo pamusoro kunononoka zvikuru kana ichinge yakanganiswa kwenguva refu ne granular media dzakadai se slurry ne jecha. Kana tichienzanisa nemapaipi esimbi akajairwa, hupenyu hwavo hwekushanda hunogona kuwedzerwa kakawanda kana kutopfuura kagumi, zvichideredza zvakanyanya kuwanda uye mutengo wekutsiva mapaipi.
Kudzivirira kupisa kwakanyanya uye kwakaderera uye kuramba ngura: Pamusoro pekusapfeka zvakanaka, silicon carbide inogonawo kuchinjika kune tembiricha dzakasiyana-siyana, uye inogona kushanda zvakadzikama munzvimbo dzakasiyana-siyana kubva paminus makumi emadhigirii Celsius kusvika kumazana emadhigirii Celsius. Panguva imwe chete, inewo kuramba kwakanaka kune zvinokuvadza zvakaita seacid nealkali, izvo zvinoita kuti ive "nehunyanzvi" muzvinhu zvakaoma zvekutakura mumaindasitiri akadai semakemikari nesimbi.
Kushanda zvakanaka kwekutakura zvinhu: Nekuda kwekuti silicon carbide lining iri pamusoro payo yakatsetseka, kuramba kwechinhu chinoyerera mupaipi kwakaderera, zvichiita kuti isanyanya kuvharika. Izvi hazvingovimbisi chete kushanda zvakanaka kwekutakura zvinhu, asiwo zvinoderedza nguva yekusashanda zvakanaka inokonzerwa nekuchenesa mapaipi.
Inoratidza hunyanzvi hwayo kupi?
Kunyangwe zvichinzwika se "zvehunyanzvi", kushandiswa kwemapaipi anodzivirira kupfeka esilicon carbide kuri pedyo zvikuru nekugadzirwa kwedu uye hupenyu hwedu:
Mumaindasitiri emigodhi nesimbi, inoshandiswa kutakura tsvina yemineral kubva mumigodhi nemarara kubva mukunyungudutsa, uye inosakara zvakanyanya kubva muzvinhu zvine huwandu hwakawanda hwezvinhu;
Muindasitiri yemagetsi, ipaipi yakakosha yekutakura upfu hwemarasha muzviteshi zvemagetsi zvinopisa, zvichiita kuti pave nekuwanikwa kwakasimba kwemafuta ebhoyira;
Mumaindasitiri ezvivakiso nemakemikari, inogona kutakura zvinhu zvesimende, zvinhu zvemakemikari, nezvimwewo, kuti ikwanise kutsungirira kusakara uye ngura diki yemidziyo yakasiyana-siyana.
Zvinogona kutaurwa kuti mune chero ndima yeindasitiri inoda kutakurwa kwemidziyo ine simba rekudzivirira kupfekwa uye mamiriro ekushanda akaomarara, kuvapo kwemapaipi anodzivirira kupfekwa esilicon carbide kunogona kuonekwa. Inopa vimbiso yakakosha yekushanda kunogara kuripo uye kwakanaka kwekugadzirwa kwemaindasitiri nekushanda kwayo "kwakaoma", uye yavewo chikamu chakakosha chemasisitimu emazuva ano ekutakura zvinhu mumaindasitiri.
