Mukugadzirwa kwemaindasitiri, mapaipi akafanana ne "tsinga dzeropa" dzemidziyo, ine basa rekutakura zvinhu "zvinodziya" zvakaita sejecha, matombo, uye magasi anodziya zvakanyanya. Nekufamba kwenguva, madziro emukati memapaipi akajairwa anosvava nyore uye anogona kutodonha mvura, zvichida kugadziriswa nguva nenguva uye kutsiviwa, uye zvinogonawo kunonotsa kufambira mberi kwekugadzirwa. Kutaura zvazviri, kuwedzera "mbatya dzekudzivirira dzakakosha" papaipi kunogona kugadzirisa dambudziko, iro ririsilicon carbide pombi yekuisa mukatitichataura nezvazvo nhasi.
Vamwe vanhu vangabvunza kuti, chii chaizvo chakatangira silicon carbide ceramics dzinonzwika se "dzakaoma"? Zvichitaurwa zviri nyore, iceramic yakagadzirwa nezvinhu zvakaoma zvakaita sesilicon carbide kuburikidza nemaitiro akakosha, uye chinhu chikuru chayo "kusimba": kuoma kwayo kuri kwechipiri kune dhaimani, uye inogona kutsungirira kuputsika kwejecha nematombo nezvinhu zvinoora zvishoma nezvishoma, kusiyana nesimbi dzakajairika dzinokurumidza kuita ngura nekusakara, uye inodzivirirawo kupisa kwakanyanya uye kukanganiswa kupfuura plastic liners.
Chinhu chikuru chekuisa silicon carbide lining mumapaipi ndechekuwedzera "chidziviriro chakasimba" kumadziro emukati. Pakuisa, hapana chikonzero chekushanda nesimba. Kazhinji, zvidimbu zve silicon carbide zvakagadzirwa kare zvinosungirirwa kumadziro emukati mepaipi ne glues dzakakosha kuti zvigadzire jira rakazara rekudzivirira. Rutivi urwu rwe 'chidziviriro' rungasaita serusina gobvu, asi basa raro rinonyanya kushanda:
Chekutanga, 'inodzivirira kupfeka zvachose'. Ingave iri kutakura zvidimbu zveore nemipendero yakapinza kana slurry inoyerera nekukurumidza, pamusoro pe silicon carbide lining inonyanya kutsvedzerera. Kana zvinhu zvikapfuura, kukweshana kudiki, izvo zvisingangokuvadzi lining chete, asiwo zvinoderedza kuramba panguva yekufambisa zvinhu, zvichiita kuti kutakurwa kuve kwakapfava. Mapaipi akajairwa angada kugadziriswa mushure mehafu yegore yekusakara, nepo mapaipi ane silicon carbide lining anogona kuwedzera hupenyu hwawo hwebasa, zvichideredza kunetseka uye mutengo wekutsiva mapaipi kakawanda.
Zvadaro pane "kuramba kwengura uye kuramba kupisa kwakanyanya". Muzviitiko zvakawanda zvemaindasitiri, zvinhu zvinotumirwa zvine zvinhu zvinoparadza zvakaita seasidhi nealkali, uye tembiricha haisi yakaderera. Matanda akajairwa anogona kunge akaora uye akatsemuka, kana kuti akakanganisika nekupisa kwakanyanya. Asi silicon carbide ceramics pachayo ine makemikari akasimba uye haatyi kukurwa kweasidhi nealkali. Kunyangwe kana ikasangana nekupisa kwakanyanya kwemazana emakore Celsius, inogona kuchengetedza chimiro chakasimba, zvichiita kuti ive yakakodzera kushandiswa kwepaipi "munzvimbo dzakaoma" dzakadai semakemikari, simbi, uye migodhi.
Chimwe chinhu chakakosha ndechekuti "hazvina kunetseka uye hazvinetsi". Mapaipi akafukidzwa nesilicon carbide haadi kuvharwa kakawanda kuti agadziriswe, uye ari nyorewo kuchengetedza - pamusoro pawo hapawanzo kukwenywa kana kuturikwa kwezvinhu, uye anongoda kucheneswa zvishoma nguva nenguva. Kune mabhizinesi, izvi zvinoreva kuderedza njodzi yekukanganiswa kwekugadzirwa uye kuchengetedza mari yakawanda yekugadzirisa vashandi nezvinhu, izvo zvakaenzana ne "kuisa kamwe chete, kusagadzikana kwenguva refu".
Vamwe vanhu vangafunga kuti jira rakadaro rinogara kwenguva refu rinodhura zvakanyanya? Kutaura zvazviri, kuverenga "akaundi yenguva refu" kwakajeka: kunyangwe mutengo wekutanga wejira rakajairika wakaderera, unofanirwa kutsiviwa mwedzi mitatu kusvika mishanu yega yega; Mari yekutanga yekuisa mari ye silicon carbide yakakwira zvishoma, asi inogona kushandiswa kwemakore akati wandei, uye avhareji yemutengo pazuva yakaderera. Uyezve, inogona kudzivirira kurasikirwa kwekugadzira kunokonzerwa nekukuvara kwepombi, uye kushanda kwemutengo kwakanyanya.
Mazuva ano, silicon carbide pipeline lining yave zvishoma nezvishoma kuva "mhinduro inodiwa" yekudzivirira mapaipi emaindasitiri, kubva kumataira anofambisa mapaipi mumigodhi, kusvika kumapaipi ezvinhu zvinoparadza muindasitiri yemakemikari, kusvika kumapaipi egasi anodziya zvakanyanya muindasitiri yemagetsi, kuvapo kwayo kunogona kuonekwa. Zvichitaurwa zviri nyore, zvakaita se "muchengeti wepamoyo" wemapaipi, achichengetedza chinyararire kushanda zvakanaka kwekugadzirwa kwemaindasitiri nekuoma kwayo uye kugara kwenguva refu - ichi ndicho chikonzero nei makambani akawanda achida kupa mapaipi "zvipfeko zvekudzivirira zvakakosha".
