Emkhiqizweni wezimboni, amapayipi afana “nemithambo yegazi” yemishini, enomthwalo wemfanelo wokuthutha izinto “ezinolaka olushisayo” njengesihlabathi, amatshe amatshe, namagesi ashisa kakhulu. Ngokuhamba kwesikhathi, izindonga zangaphakathi zamapayipi avamile ziguga kalula futhi zingavuza, okudinga ukulungiswa njalo nokushintshwa, futhi kungase kubambezele ukuqhubeka kokukhiqiza. Eqinisweni, ukwengeza ungqimba “lwezingubo zokuvikela ezikhethekile” epayipini kungaxazulula inkinga, okuyii-silicon carbide pipeline lineningsizokhuluma ngayo namuhla.
Abanye abantu bangase babuze, uyini ngempela umsuka we-silicon carbide ceramics ezwakala "i-hardcore" ngempela? Kalula nje, iyi-ceramic material eyenziwe ngezinto eziqinile njenge-silicon carbide ngezinqubo ezikhethekile, futhi isici sayo esikhulu kunazo zonke "ukuqina": ukuqina kwayo kungokwesibili ngemuva kwedayimane, futhi ingakwazi ukumelana nokuguguleka kwesihlabathi namatshe kanye nezinto ezibolayo kancane kancane, ngokungafani nama-liner ensimbi avamile ajwayele ukugqwala futhi aguge, futhi futhi imelana kakhulu nezinga lokushisa eliphezulu kanye nemithelela yepulasitiki.
Umnyombo wokufaka i-silicon carbide lining kumapayipi ukufaka "umgoqo oqinile" odongeni lwangaphakathi. Lapho ufaka, asikho isidingo sokwenza umzamo omkhulu. Isikhathi esiningi, izingcezu ze-silicon carbide ceramic ezenziwe ngaphambili ziboshelwa odongeni lwangaphakathi lwepayipi ngezinamatheliso ezikhethekile ukuze zakhe ungqimba oluphelele lokuvikela. Lolu ngqimba 'lwesithiyo' lungase lungabonakali luwugqinsi, kodwa umsebenzi walo usebenza ngokukhethekile:
Okokuqala, 'ukumelana nokugqokwa okugcwele'. Kungakhathaliseki ukuthi ithutha izinhlayiya ze-ore ezinemiphetho ebukhali noma udaka olugeleza ngesivinini esiphezulu, ingaphezulu le-silicon carbide lining libushelelezi ngokukhethekile. Lapho impahla idlula, ukungqubuzana kuncane, okungalimazi nje ulwelwesi, kodwa futhi kunciphisa ukumelana ngesikhathi sokuthutha izinto ezibonakalayo, okwenza ukuthutha kube lula. Amapayipi avamile angase adinge ukunakekelwa ngemva kwesigamu sonyaka sokuguga, kuyilapho amapayipi ane-silicon carbide lining anganweba kakhulu isikhathi sawo sesevisi, ehlise ubunzima nezindleko zokushintsha amapayipi ngokuphindaphindiwe.
Bese kuba khona "ukumelana nokugqwala kanye nomugqa ombaxambili wokumelana nokushisa okuphezulu". Ezimweni eziningi zezimboni, izinto ezidluliswayo zithwala izakhi ezonakalisayo njenge-asidi ne-alkali, futhi izinga lokushisa aliphansi. Izindwangu ezivamile zingagqwala futhi ziqhekeke, noma zikhubazeke ngenxa yokubhaka okuphezulu kwezinga lokushisa. Kodwa ama-ceramics e-silicon carbide ngokwawo anezindawo zamakhemikhali ezinzile futhi awesabi ukuguguleka kwe-asidi ne-alkali. Ngisho nalapho echayeke emazingeni okushisa angamakhulu ambalwa e-Celsius, angagcina ifomu elizinzile, awenze afanelekele ukusetshenziswa kwamapayipi “ezindaweni ezinokhahlo” njengamakhemikhali, i-metallurgical, nezimayini.
Elinye iphuzu elibalulekile "ukukhathazeka mahhala futhi kulula". Amapayipi afakwe i-silicon carbide awadingi ukuvalwa njalo ukuze agcinwe, futhi kulula ukuwagcina - indawo engaphezulu ayijwayele ukukala noma ukulenga impahla, futhi idinga ukuhlanzwa kancane njalo. Emabhizinisini, lokhu kusho ukwehlisa ingcuphe yokuphazamiseka kokukhiqiza kanye nokonga izindleko eziningi zomsebenzi wokulungisa kanye nezinto ezibonakalayo, okulingana “nokufakwa kanye kuphela, ungakhathazeki isikhathi eside”.
Abanye abantu bangase bacabange ukuthi ulwelwesi oluhlala njalo lubiza kakhulu? Eqinisweni, ukubala "i-akhawunti yesikhathi eside" kucacile: nakuba izindleko zokuqala zomugqa ojwayelekile ziphansi, zidinga ukushintshwa njalo ezinyangeni ezintathu kuya kwezinhlanu; Ukutshalwa kwezimali kokuqala kwe-silicon carbide lining kuphakeme kancane, kodwa kungasetshenziswa iminyaka eminingana, futhi izindleko ezijwayelekile ngosuku empeleni ziphansi. Ngaphezu kwalokho, ingagwema ukulahlekelwa kokukhiqiza okubangelwa ukulimala kwamapayipi, futhi ukuphumelela kwezindleko empeleni kuphezulu kakhulu.
Namuhla, ulayini lwamapayipi e-silicon carbide kancane kancane seluphenduke “isixazululo esithandwayo” sokuvikela amapayipi ezimboni, kusukela ezinsikeni ezidlulisa amapayipi ezimayini, kuya kumapayipi ezinto ezonakalisayo embonini yamakhemikhali, kuya kumapayipi egesi eshibhile enamazinga okushisa aphezulu embonini yamandla, ubukhona bawo bungabonakala. Kalula nje, kufana “nonogada bomuntu siqu” wamapayipi, eqapha buthule ukusebenza kahle kokukhiqizwa kwezimboni ngobulukhuni nokuqina kwayo - lokhu futhi yingakho izinkampani eziningi zizimisele ukuhlomisa amapayipi ngale “mpahla yokuvikela ekhethekile”.
