Ubungakanani bemibhobho yerhasi bunokuqala ukusuka kwi-2 ukuya kuma-60 intshi ubukhulu ngelixa, kwimibhobho yeoyile iqala kwi-4 ukuya kuma-48 intshi yangaphakathi ngokuxhomekeka kwimfuno.Umbhobho weoyileinokwenziwa nokuba yintsimbi okanye iplastiki kodwa eyona isetyenziswa kakhulu ngumbhobho wentsimbi.Iibhobho zentsimbi ezifakwe kwi-thermal zisetyenziswa ngokuqhelekileyo ekuthuthweni kweoli kunye negesi.

Izibonelelo zemibhobho yentsimbi:
Imibhobho yentsimbi engcwatywe amakhulu eminyaka ineempawu ezingaqhelekanga ezibandakanya ukuxhathisa okugqwesileyo kokuqhekeka kwerhasi yendalo.Zingcolisekile kwaye zinempembelelo ephezulu yokuchasa, iqondo eliphezulu le-HDB kwi-20°C, 60°C kunye ne-80°C, ukunyanzeliswa okuphantsi kwemethane nehydrogen.Inentsebenzo emangalisayo ye-UV ethembekileyo yokugcina ngaphandle.I-insulation material idla ngokuba yi-polyurethane foam (PU) enokusebenza kakuhle kwe-thermal kwaye yomelele ngoomatshini.

Eyona mibhobho yeoli nerhasi:
Iibhobho zentsimbi ezincinci, eziphakathi kunye nobukhulu obukhulu ziyafumaneka nangona kunjalo, ukomelela okuphezulu kwentsimbi kwenza ukugoba kunye nokwenza nzima ngakumbi.Ngokuqhelekileyo, i-Electric Resistance Welded (ERW) ipayipi yensimbi isetyenziselwa ukusetyenzwa kweoli kunye negesi kunye neentambo zokuhambisa ezibhalisiweyo eziqinisekisa umgangatho ohambelanayo kwisicelo sayo.Imibhobho ye-ERW ilungile ngokulinganayo kwiindawo ezishushu okanye ezimanzi njengokuwela umlambo kunye nomhlaba omagingxigingxi.

Ukubaluleka kweqhinga lokuthuthwa kweoli kunye negesi kunye nokuhanjiswa kokunikezelwa kwamandla kuye kwagxininisa ukuveliswa kweepayipi zentsimbi kunye neetyhubhu.Ukuqinisekiswa kokubola, ipeyinti esekelwe emanzini isetyenziswe kumphezulu wombhobho ongaphandle ukukhusela kwi-atmospheric corrosion ngexesha lokuthutha kunye nokugcinwa kunye ne-3-layer yokukhusela i-PE yokukhusela ingasetyenziswa kwimibhobho ngokwesicelo soMthengi.

Imibhobho yentsimbi yomgca yimibhobho yomgama omde yolwelo olunokutsha kunye neegesi.Imibhobho yemigca engenamthungo esetyenziselwa ukwakhiwa kwemibhobho yomgama omde yolwelo olunokutsha neerhasi, imibhobho yesikhululo senyukliya, imibhobho yesixokelelwano sokufudumeza, imibhobho yenjongo jikelele.Ke ngoko, iimfuno zokuqina kwimibhobho yentsimbi yomgca zinzima ngakumbi kuneemfuno zepropathi ezixineneyo.

Imibhobho yentsimbi yomgca yenziwe kwaye inyibilika kwisithando sombane, iphathwa nge-slags yokwenziwa kwaye iphoswe ngama-casters aqhubekayo.Inkqubo yokwenza isinyithi esetyenzisiweyo iqinisekisa ukufezekiswa kweekhemikhali zentsimbi ecocekileyo ngokubhekiselele kwi-sulfure kunye ne-phosphor iziqulatho ezibonelela nge-tensile ephezulu, i-ductility kunye neempawu zokumelana nokubola kwemibhobho ukuba iqhutywe kumaqondo okushisa aphantsi kwimidiya eyahlukeneyo ye-corrosion.

Imibhobho yentsimbi efakwe kwi-thermal ibaluleke kakhulu kwishishini leoli negesi.Imibhobho yentsimbi, engcwatywe amakhulu eminyaka, ineempawu ezingaqhelekanga ezibandakanya ukuxhathisa okugqwesileyo kokuqhekeka kwerhasi yendalo kunye nezinto ezingcolisayo, ukungena okuphantsi kwemethane kunye nehydrogen, iqondo eliphezulu leHDB kuma-20°C, 60°C kunye nama-80°C, ngaphezulu. Ukuchasa impembelelo, ukucudisa, kunye nokusebenza okuthembekileyo kwe-UV kugcino lwangaphandle.I-insulation material idla ngokuba yi-polyurethane foam (PU), enokusebenza kakuhle kwe-thermal kwaye yomelele ngoomatshini.

Imibhobho edayamitha emincinci, ephakathi kunye nenkulu iyafumaneka kwaye ukomelela okuphezulu kwentsimbi kwenza ukugoba kunye nokwenza nzima ngakumbi.Ngokuqhelekileyo, i-Electric Resistance Welded (ERW) yentsimbi yePipe isetyenziselwa ukusetyenzwa kweoli kunye negesi kunye nemigca yokuhambisa ebhalisiwe kwaye iqinisekisa umgangatho ohambelanayo kwisicelo sayo.Le mibhobho yeoli neyerhasi ilungile ngokulinganayo kwiindawo ezishushu okanye ezimanzi ezifana nokuwela imilambo kunye nomhlaba omagingxigingxi.Ukusetyenziswa kwentsimbi kunika umgangatho wombhobho ofanelekileyo wokusetyenziswa ekuhambiseni igesi, amanzi kunye neoli kuzo zombini i-oyile kunye negesi yendalo.
