Kwimimandla yemizi-mveliso efana neekhemikhali, i-metallurgical, kunye nemigodi, iipayipi zezona ndlela ziphambili zokuthutha izinto, kwaye indlela yokuhambisa idla ngokuba "namandla okubulala" afana nokuguguleka, ukubola, kunye nobushushu obuphezulu. Iipayipi eziqhelekileyo zinokwaluphala kwaye zivuza, nto leyo engachaphazeli kuphela ukusebenza kakuhle kwemveliso kodwa ikwabeka neengozi zokhuseleko ezifihlakeleyo.I-silicon carbide pipeline liningsisixhobo sokukhusela semizi-mveliso esenzelwe ukusombulula eli nqanaba lentlungu, kwaye siye saba sisisombululo esithandwayo sokugqwala okunamandla kwimizi-mveliso kunye neemeko zokuguguleka okuphezulu ngenxa yokusebenza kwayo okugqwesileyo.
Umgca wepayipi ye-silicon carbide, ngamafutshane, lulwaleko olukhuselayo lwezinto ze-silicon carbide ezidityanisiweyo eludongeni lwangaphakathi lombhobho, nto leyo ebeka "isikrweqe" esomeleleyo kumbhobho. Ngokungafaniyo nee-liners zesinyithi okanye zeplastiki eziqhelekileyo, i-silicon carbide ngokwayo sisixhobo esibalaseleyo se-ceramic yemizi-mveliso esinokuziqhelanisa neemeko zokusebenza ezinzima, nto leyo enika ii-liners zepayipi ye-silicon carbide inzuzo ephambili eyahlula kwii-liners zemveli.
Ukumelana nokuguguleka kunye nokumelana nokugqwala zezona zinto ziphambili kwi-silicon carbide pipeline lining. Kwizithuthi zoshishino, imidiya efana ne-slurry, i-powder, i-acid alkali solution, njl. ingaba nobunzima obuphezulu kwaye ithambekele ekugugulekeni kwemibhobho, okanye ithambekele ekugqwaleni okukhulu kwaye ithambekele ekugugulekeni kweendonga zemibhobho. Izinto ze-silicon carbide zinobunzima obuphezulu kakhulu, zilandela idayimani kuphela, kwaye zinokumelana ngokulula nokuguguleka kunye nokugqwala kwezinto ezahlukeneyo eziqinileyo; Kwangaxeshanye, ineempawu zeekhemikhali ezizinzileyo kwaye ayoyiki ukugqwala kwe-asidi kunye ne-alkali okanye i-oxidation yobushushu obuphezulu. Nokuba isebenza kwiindawo ezinamandla ze-asidi kunye ne-alkali, ezinobushushu obuphezulu ixesha elide, inokugcina uzinzo lwesakhiwo kwaye inciphise kakhulu amathuba okonakala kunye nokuvuza kwemibhobho.
Ukumelana nobushushu obuphezulu kunye nokuqhuba kakuhle kobushushu kwenza ukuba ifaneleke kwiimeko zokusebenza ezinzima ngakumbi. Izinto ezininzi kwimveliso yemizi-mveliso kufuneka zithuthwe kwiindawo ezinobushushu obuphezulu, kwaye ii-liners eziqhelekileyo zinokuguquguquka kwaye ziguge ngenxa yobushushu obuphezulu. Nangona kunjalo, i-silicon carbide inokumelana nobushushu obuphezulu kakhulu kwaye ihlangabezane neemfuno ezikhethekileyo zeemeko zokusebenza ezinobushushu obuphezulu, nto leyo eyandisa ububanzi bokusetyenziswa kwemibhobho.
Ukongeza, i-silicon carbide pipeline lining ikwaneengenelo zobomi obude benkonzo kunye neendleko eziphantsi zokugcinwa. I-pipeline yendabuko ifuna ukutshintshwa rhoqo kunye nokugcinwa, okungasebenzisi nje kuphela amandla abasebenzi kunye nezixhobo, kodwa kunye nokulibazisa inkqubela yemveliso. Ukuqina kwe-silicon carbide lining kunamandla kakhulu, kwaye inokusebenza ngokuzinzileyo ixesha elide ngokufakelwa kube kanye, okunciphisa kakhulu ukuphindaphindwa kokugcinwa kunye nokutshintshwa kwinqanaba lokugqibela. Ekugqibeleni, inokonga iindleko ezininzi zokusebenza kunye nokugcinwa kwamashishini kwaye iqinisekise ukuqhubeka kwemveliso.
Ngenxa yokwanda kwemfuno yokhuseleko lokuthuthwa, ukusebenza kakuhle, kunye nokuzinza kwimveliso yemizi-mveliso, umgca wepayipi ye-silicon carbide uye wasetyenziswa kakhulu ngenxa yeenzuzo zayo eziphambili zokuxhathisa ukuguguleka, ukumelana nokugqwala, kunye nokumelana nobushushu obuphezulu. Ayisiyo nje kuphela umaleko wokukhusela imibhobho, kodwa ikwasisiqinisekiso esithembekileyo semveliso yokhuseleko lweshishini, ukunciphisa iindleko kunye nokuphucula ukusebenza kakuhle. Kwinkqubo yophuhliso lwemizi-mveliso olukumgangatho ophezulu, iba "luxanduva lokhuseleko olukumgangatho ophezulu" kwicandelo lokuthuthwa kwemizi-mveliso kunye nokusebenza kwayo okuqinileyo.
