I-Induction Preheating for Oil and Gas Pipelines: Kungani Kubalulekile Ngaphambi Kokushisela.
Amapayipi kawoyela negesi abalulekile ekuthuthweni kukawoyela negesi amabanga amade. Zakhelwe ukumelana nezimo ezinzima zemvelo njengokushintsha kwezinga lokushisa elibi kakhulu, umoya onamandla, kanye nemvula enamandla. 
Inqubo yokushisela esetshenziselwa ukuhlanganisa la mapayipi ibalulekile ekuthembekeni kwawo, kodwa ingabangela izinkinga uma ingenziwanga kahle. Isixazululo esisodwa salokhu ukushisa kwe-induction. Le nqubo ifakazelwe ukuthi iyasebenza ekuthuthukiseni ikhwalithi yokushisela amapayipi kanye nokunciphisa ingozi yokukhubazeka ekushiseleni. Kulesi sihloko, sizoxoxa ngokuthi kungani ukushisa kwe-induction kubalulekile ngaphambi kokushisela amapayipi kawoyela negesi, ukuthi asebenza kanjani, kanye nezinzuzo ezinganikeza.
1. Kuyini ukushisa kwe-induction futhi kusebenza kanjani?
Ukukhipha ukushisa kuyinqubo esetshenziswa ekushiseleni amapayipi kawoyela negesi ukusiza ukuqinisekisa ikhwalithi nokuphila isikhathi eside kokushisela. Le ndlela yokushisisa ngaphambili isebenzisa amaza kagesi ukushisisa insimbi ngaphambi kokushisela. Umnyombo wesistimu yokushisa yokungeniswa kwe-induction iyikhoyili yokungeniswa, eboshwe eduze kwepayipi elishiselwe. 
Ikhoyili idala insimu kazibuthe eyenza amandla kagesi angene ensimbi, akhiqize ukushisa. Lokhu kushisa bese kusakazwa ngokulinganayo kuyo yonke insimbi, okusiza ukuvimbela ukushaqeka okushisayo phakathi nenqubo yokushisela. Lokhu kubalulekile ngoba ukushaqeka okushisayo kungabangela ukuqhekeka kwensimbi, okungaholela ekuvuzeni kwepayipi. Ukushisa kwe-induction nakho kusiza ukunciphisa ingozi yokuqhekeka kwe-hydrogen, okungenzeka lapho kushiselwa emazingeni okushisa abandayo. Ngokusebenzisa i-induction preheating, i-welder ingaqinisekisa ukuthi insimbi isezingeni lokushisa elifanele lokushisela, okusiza ukukhiqiza i-weld eqinile futhi enokwethenjelwa. Sekukonke, ukushisa kwe-induction kuyisinyathelo esibalulekile enqubweni yokushisela yamapayipi kawoyela negesi, futhi kusiza ukuqinisekisa ukuphepha nokuthembeka kwamapayipi eminyakeni ezayo.
2. Ukubaluleka kokushisa kokungeniswa ngaphambi kokushisela amapayipi kawoyela negesi
Ukushisa kwe-induction kuyinqubo ebalulekile okufanele yenziwe ngaphambi kokushisela amapayipi kawoyela negesi. 
Lokhu kungenxa yokuthi ukushisela kuhilela ukushisa izingcezu ezimbili zensimbi ezingeni lokushisa eliphezulu kakhulu bese zihlanganiswa ndawonye. Uma insimbi ingashiswa kahle ngaphambi kokushisela, ingabangela izinkinga eziningi. Enye yezinkinga eziyinhloko ukuthi insimbi ingaba brittle futhi ijwayele ukuqhekeka, okungaholela ekuvuzeni nezinye izinkinga ezinkulu. Ukushisa kwe-induction kuyinqubo eshisisa insimbi ezingeni lokushisa elithile ukuze kuqinisekiswe ukuthi isilungele ukushiselwa. Le nqubo ihlanganisa ukusebenzisa i ukufakwa kokushisa uhlelo ukushisa insimbi ezingeni lokushisa elifanele ngaphambi kokushisela. Izinzuzo ze-induction preheating zibalulekile. Kungasiza ukunciphisa ingozi yokuqhekeka nezinye izinhlobo zokulimala kwensimbi ngesikhathi sokushisela. Kungasiza futhi ukuthuthukisa ikhwalithi ye-weld futhi kunciphise amathuba okuba namaphutha. Ngaphezu kwalokho, ukushisa kwe-induction preheating kungasiza ekunciphiseni isikhathi nezindleko zenqubo yokushisela ngokuvumela i-welder ukuthi isebenze ngokuphumelelayo. Sekukonke, ukushisa kwe-induction kuyinqubo ebalulekile okungafanele inganakwa lapho kushiselwa amapayipi kawoyela negesi.
3. Izinzuzo zokushisisa kokungeniswa
Ukushisa kwe-induction kuyinqubo ebalulekile yamapayipi kawoyela negesi ashiselwa ndawonye. Inqubo ibandakanya ukusetshenziswa kokungeniswa kwe-electromagnetic ukushisa ipayipi ngaphambi kokuba inqubo yokushisela iqale. Le nqubo ibaluleke kakhulu ngoba isiza ukuvimbela uhla lwezinkinga ezingase ziphakame ngesikhathi senqubo yokushisela. Enye yezinzuzo ezibaluleke kakhulu ze-induction prehe
ukulinganisa ukuthi kusiza ukuvimbela ukungqubuzana nokuhlanekezelwa kwepayipi. Lokhu kungenxa yokuthi ukushisa kusakazwa ngokulinganayo epayipini lonke, okusiza ukugcina insimbi ingakhuli noma ifinyezeke ngokweqile. Ukushisa kwe-induction nakho kusiza ekwehliseni ubungozi bokuqhekeka, okungenzeka lapho insimbi ibekwe emazingeni okushisa aphezulu bese iphola ngokushesha kakhulu. Okokugcina, ukushisa kwe-induction kusiza ukudala i-weld engaguquki futhi enokwethenjelwa. Ukushisa kusakazwa ngokulinganayo, okusiza ukuqinisekisa ukuthi i-weld iqinile futhi ivikelekile. Sekukonke, ukushisisa kokungenisa kuyisinyathelo esibalulekile enqubweni yokushisela yamapayipi kawoyela negesi, futhi kunikeza uhla lwezinzuzo ezisiza ukuqinisekisa ukuthi umkhiqizo wokugcina uphephile, uthembekile, futhi uhlala isikhathi eside.
4. Isiphetho.
Sengiphetha, ukushisa kwe-induction kuyisinyathelo esibalulekile enqubweni yokushisela yamapayipi kawoyela negesi. Ukusetshenziswa kobuchwepheshe bokushisa kwe-induction kuqinisekisa ukuthi ipayipi ishisa ngaphambi kokushisa okudingekayo ngaphambi kokushisela, okusiza ukunciphisa ingozi yokuqhekeka, ukuhlanekezela, nokunye ukukhubazeka kokushisela. Kuyasiza futhi ukuqinisekisa ukuthi i-weld iqinile, ihlala isikhathi eside, futhi ihlala isikhathi eside. Izinzuzo zokusebenzisa i-induction preheating ohlelweni lokushisela ipayipi likawoyela negesi zicacile - kusiza ukuthuthukisa ikhwalithi ye-weld, kunciphisa amathuba okuhluleka kwe-weld, futhi ekugcineni konga isikhathi nemali. Ngaphezu kwalokho, ukusetshenziswa kobuchwepheshe bokushisa kwe-induction ku-eco-friendly futhi kunciphisa i-carbon footprint yenqubo yokushisela. Ngakho-ke, uma uhileleke embonini kawoyela negesi, kubalulekile ukuthi ucabangele ukusebenzisa ukushisa kwe-induction ukuze uqiniseke ukuthi ukushisela kwepayipi lakho kwenziwa ngendlela efanele nangempumelelo.
