Itekhnoloji yokwandisa i-Thermal isetyenziswe ngokubanzi kwi-petroleum,ishishini lemichiza, amandla ombane kunye namanye amashishini kwiminyaka yakutshanje, kunye neyona ndawo ibalulekileyo yesicelo yimibhobho ye-oyile.Imibhobho yentsimbi engenamthungo ecutshungulwa bubuchwephesha bokwandiswa kwe-thermal ineengenelo zokuzinza kwe-dimensional, umphezulu ogudileyo, kwaye akukho ziphene zangaphakathi.Ukongeza, ukwandiswa kwe-thermal kukwasetyenziselwa ukwandiswa kwe-diameter yangaphakathi, ukunciphisa igobolondo, ukucutshungulwa kwekona, njl.

Umbhobho wentsimbi owandisiweyo ongenamthungo luhlobo lombhobho wentsimbi ongenamthungo owenziwe ngokufudumeza kunye nenkqubo yokwandisa ububanzi.Xa kuthelekiswa nemibhobho yentsimbi engenamthungo etsalwa ngokubanda, imibhobho yentsimbi eyandisiweyo engenamthungo inobunzima obuncinane bodonga kunye nedayamitha yangaphandle enkulu.Inkqubo yokwenziwa kwemibhobho yentsimbi engenamthungo eyandisiweyo ibandakanya ukugqobhoza okuninzi, ukufudumeza, ukwandiswa kobubanzi, ukupholisa kunye namanye amanyathelo.Le nkqubo yokuvelisa inokuqinisekisa ukuba indawo yangaphakathi nangaphandle yombhobho igudileyo kwaye ineempawu ezintle zoomatshini.
Ukwandiswa kwe-thermal kwimibhobho yentsimbi yinkqubo yokuvelisa imibhobho yentsimbi esetyenziswa ngokuqhelekileyo.Inkqubo yokuvelisa kwayo inokwahlulwa ibe ngamanyathelo alandelayo: ukulungiswa kwezinto, ukufudumala, ukwanda kwe-thermal kunye nokupholisa.
Okokuqala, lungiselela izixhobo.Iimathiriyeli ekrwada ezisetyenziswa ngokuqhelekileyo ziyimibhobho yentsimbi engenamthungo kunye ne-welded edla ngokusetyenziswa kwishishini leoli negesi.Le mibhobho yensimbi idinga ukuhlolwa komgangatho ngaphambi kokuvelisa ukuqinisekisa umgangatho ofanelekileyo.Umbhobho wentsimbi ke uyasikwa kwaye ulungiswe ukuqinisekisa ukuba ubukhulu nobude obuchanekileyo.
Okulandelayo yisigaba sokufudumala.Beka umbhobho wensimbi kwisithando somlilo esitshisayo kwaye ushushu kwiqondo lokushisa elifanelekileyo.Injongo yokushisa kwangaphambili kukunciphisa uxinzelelo kunye nokuguqulwa ngexesha lokwandiswa kwe-thermal elandelayo kunye nokuqinisekisa umgangatho opheleleyo kunye nokusebenza kombhobho wensimbi.
Emva koko faka isigaba sokwandiswa kwe-thermal.Umbhobho wensimbi wangaphambili ufakwe kwi-expander yepayipi, kwaye umbhobho wensimbi uyandiswa nge-radially ngamandla okwandisa umbhobho.Izandisi zemibhobho zihlala zisebenzisa iirola ezine tapered, enye imile kwaye enye iyajikeleza.Iirola ezijikelezayo zityhala izinto kudonga lwangaphakathi lombhobho wensimbi ngaphandle, ngaloo ndlela ukwandisa umbhobho wentsimbi.
Ngethuba lenkqubo yokwandisa i-thermal, umbhobho wensimbi uchaphazeleka ngamandla kunye nokuxutywa kwee-roller, kwaye ukushisa kuya kwanda.Oku akukwazi ukufezekisa kuphela ukwandiswa kombhobho wensimbi, kodwa nokuphucula isakhiwo sangaphakathi sombhobho wensimbi kunye nokuphucula iimpawu zayo zomatshini.Ngexesha elifanayo, ngenxa yonyanzeliso oluqhutywe kwipayipi yensimbi ngexesha lokwandiswa kwe-thermal, inxalenye yoxinzelelo lwangaphakathi nayo inokupheliswa kwaye i-deformation yombhobho wensimbi ingancitshiswa.
Ekugqibeleni, kukho inqanaba lokupholisa.Emva kokuba ukwandiswa kwe-thermal kugqityiwe, umbhobho wensimbi kufuneka upholiswe ukuze ubuyele kwiqondo lokushisa.Ngokuqhelekileyo, umbhobho wentsimbi unokupholiswa usebenzisa isipholile, okanye umbhobho wentsimbi unokuvunyelwa ukuba uphole ngokwemvelo.Injongo yokupholisa kukuqhubela phambili ukuzinzisa isakhiwo sombhobho wensimbi kunye nokukhusela umonakalo obangelwa ukunciphisa ubushushu okukhawulezayo.
Ukushwankathela, inkqubo yokuvelisa imibhobho yentsimbi eyandisiweyo nge-thermal ibandakanya amanyathelo amane aphambili: ukulungiswa kwezinto, ukufudumala, ukwanda kwe-thermal kunye nokupholisa.Ngale nkqubo, imibhobho yentsimbi eyandisiweyo eshushu enomgangatho ophezulu kunye nokusebenza okugqwesileyo kunokuveliswa.
Njengobuchwephesha obusebenzayo kunye nomgangatho ophezulu wokuqhuba umbhobho, inkqubo yokwandiswa kwe-thermal yemibhobho yentsimbi engenamthungo isetyenziswe ngokubanzi kwi-petroleum, ishishini lemichiza, amandla ombane kunye namanye amashishini.Kwizicelo ezisebenzayo, kuyimfuneko ukubeka ingqalelo kwimiba efana nomgangatho wombhobho wensimbi, ubushushu bokucubungula kunye nexesha, ukukhuselwa kwesikhunta, njl., Ukuqinisekisa imiphumo yokucubungula kunye nomgangatho wemveliso.
Izinto eziqhelekileyo zokwandiswa kwe-thermal ziquka:Q345, 10, 20, 35, 45, 16Mn, i-alloy structural steel, njl.
