Insimbi engenasici isetyenziswa kakhulu kumashishini amaninzi ngenxa yokumelana nokugqwesa kwayo okugqwesileyo, ukuqina kunye nobuhle. Iza ngeendlela ezininzi, kubandakanywa imibhobho kunye neebhubhu ezisetyenziselwa iinjongo ezahlukeneyo. Kweli nqaku, siza kujonga ngakumbi kwihlabathi lemibhobho yensimbi engenasici kwaye sigxile kumahluko phakathi kwemibhobho yentsimbi engenamthungo kunye nentsimbi.
Okokuqala, kubalulekile ukuqonda umahluko phakathi kwemibhobho kunye ne-tubing. Nangona la magama esoloko esetyenziswa ngokufanayo, aneempawu ezithile eziwahlulayo. Imibhobho, ngokuqhelekileyo ilinganiswa nge-diameter yayo yangaphakathi (ID), yenzelwe ukuthutha ngokufanelekileyo ulwelo okanye iigesi. Ngokwahlukileyo, umbhobho ulinganiswa ngedayimitha yangaphandle (OD) kwaye ngokuqhelekileyo isetyenziswa kusetyenziso lwesakhiwo okanye kwiinjongo zokuhambisa.
Ngoku, makhe siphengululeimibhobho yentsimbi engenamthungo. Njengoko igama libonisa, umbhobho ongenamthungo awunazo ii-welds kunye nobude bombhobho. Ziveliswa ngokugqobhoza intsimbi eqinileyo engenanto kwaye extruding phezu mandrel ukwenza imilo efunekayo kunye nobukhulu. Le nkqubo yokuvelisa iphelisa imfuno ye-welding, ngaloo ndlela ikhulisa amandla ombhobho kunye nokumelana noxinzelelo.
Imibhobho yentsimbi engenamthungozineentlobo ngeentlobo zeempawu eziphezulu. Okokuqala, azikho i-seams, ziqinisekisa iindawo zangaphakathi ezigudileyo kunye nezihambelanayo, ukunciphisa umngcipheko wokubola kunye nokuguguleka. Olu phawu lubaluleke kakhulu kwizicelo apho imidiya ethunyelwayo inokonakalisa umphezulu kwaye ibeke esichengeni isidima sombhobho. Okwesibini, umbhobho ongenamthungo unamandla aphezulu okuzibamba kunombhobho odityanisiweyo, uwenza ulungele usetyenziso olufuna imfezeko yolwakhiwo eyongeziweyo kunye nokuqina. Ukongezelela, ukungabikho kwe-welds kunciphisa ukuvuza okanye ukungaphumeleli, ukunika umbhobho wensimbi engenamthungo inzuzo kumashishini abalulekileyo afana neoli kunye negesi okanye i-chemical processing plant.
Kwelinye icala, imibhobho yentsimbi engatyiwayo inokudityaniswa okanye ingenamthungo. Umbhobho wentsimbi edityanisiweyo wenziwa ngokuqengqeleka umcu osicaba wensimbi engenasiphene ibe yimilo eyicylindrical kunye nokuwelda imithungo. Le nkqubo ye-welding, ngelixa isebenzayo kwaye ingabizi kakhulu, ibangela ukuba iindawo ezibuthathaka kwi-seam, okwenza umbhobho ube sengozini yokuvuza, ukubola kunye nokukhathala. Nangona kunjalo, umbhobho odityanisiweyo usafaneleka kwizicelo ezingafuneki kangako, njengemibhobho okanye iinkqubo zokunkcenkceshela, apho uxinzelelo kunye nokuhlwa kwemithombo yeendaba ehanjiswayo iphantsi ngokwentelekiso.
Ukuqukumbela, umahluko omkhulu phakathi kombhobho wentsimbi engenamthungo kunye nombhobho wensimbi engenasici yinkqubo yabo yokuvelisa kunye nokusetyenziswa okujoliswe kuko. Iveliswe ngaphandle kwayo nayiphi na i-welds kwaye ilinganiswe ngobubanzi obungaphandle, imibhobho engenamthungo inika amandla aphezulu, ukuxhathisa ukubola kunye nokuthembeka, okwenza ukuba ibe yinto ebaluleke kakhulu kumashishini abalulekileyo. Ngakolunye uhlangothi, umbhobho wensimbi engenasici, nokuba i-welded okanye ingenamthungo, isetyenziswa ngokuqhelekileyo kwizicelo ezingabizi kakhulu apho ukuphumelela kweendleko kuthatha indawo yokuqala ngaphezu kwamanqanaba aphezulu okuqina kunye nokunyaniseka. Xa ukhetha umbhobho ongenamthungo kunye nombhobho, kubalulekile ukuqwalasela iimfuno ezithile zesicelo esijoliswe kuyo kwaye udibane neengcali zoshishino ukuqinisekisa ukuba ukhetho olufanelekileyo lwenziwa.
