Umbhobho wensimbi ojikelezayo usetyenziswa kakhulu kwiprojekthi yamanzi epompo, ishishini lepetrochemical, ishishini lemichiza, ishishini lamandla ombane, ukunkcenkceshela kwezolimo kunye nokwakhiwa kwedolophu. Yenye yeemveliso ezingundoqo ezingama-20 eziphuhliswe eTshayina.
Umbhobho wentsimbi ye-Spiral ungasetyenziswa kumashishini ahlukeneyo. Iveliswa ngokwenkqubo ethile kunye neenkqubo zokuvelisa kwaye idlala indima ebalulekileyo ekwakheni ukwakhiwa. Ngokunyuka koxinzelelo lokuthwala kunye nokwanda kwenkonzo engqongqo, kuyimfuneko ukwandisa ubomi benkonzo yombhobho kangangoko kunokwenzeka.
Olona lwalathiso luphambili lophuhliso lombhobho wentsimbi ejikelezayo lu:
(1) Yila kwaye uvelise imibhobho yentsimbi enesakhiwo esitsha, njengemibhobho yentsimbi edityanisiweyo ephindwe kabini. Yimibhobho ephindwe kabini edityaniswe ngentsimbi yomtya, sebenzisa ubukhulu besiqingatha sodonga lombhobho oluqhelekileyo ukuze ludityaniswe kunye, luya kuba namandla angaphezulu kunemibhobho enomgangatho omnye enobunzima obufanayo, kodwa ayizukubonisa ukungaphumeleli okuqinileyo.
(2) Ukuphuhlisa ngamandla imibhobho egqunyiweyo, njengokwaleka udonga lwangaphakathi lombhobho. Oku akuyi kwandisa kuphela ubomi benkonzo yombhobho wensimbi, kodwa kwakhona kuphuculwe ukuguquguquka kodonga lwangaphakathi, ukunciphisa ukuxhathisa ukuxhatshazwa kwamanzi, ukunciphisa i-wax kunye nokungcola, ukunciphisa inani lokucoca, ngoko ukunciphisa iindleko zokugcinwa.
(3) Phuhlisa amabakala amatsha entsimbi, uphucule umgangatho wobugcisa wenkqubo yokunyibilikisa, kwaye wamkele ngokubanzi inkqubo yokuqengqeleka elawulwayo kunye nokuqengqeleka kwenkunkuma, ukuze kuphuculwe ngokuqhubekayo amandla, ukuqina kunye nokusebenza kwe-welding yomzimba wombhobho.
Umbhobho wentsimbi odityanisiweyo wobubanzi obukhulu uqatywe ngeplastiki ngokwesiseko sombhobho odityanisiweyo ojikelezayo omkhulu we-diameter kunye ne-high-frequency welded pipe. Inokuthi ifakwe nge-PVC, i-PE, i-EPOZY kunye nezinye iingubo zeplastiki zeempawu ezahlukeneyo ngokweemfuno ezahlukeneyo, kunye nokubambelela kakuhle kunye nokuxhathisa okuqinileyo kwe-corrosion. Iasidi eyomeleleyo, ialkali kunye nezinye iikhemikhali zokuxhathisa umhlwa, non-ityhefu, akukho mhlwa, ukumelana ukunxiba, ukumelana impembelelo, ukumelana permeability, umbhobho agudileyo umphezulu, akukho ukunamathela kuyo nayiphi na into, kunokunciphisa ukuxhathisa kwezothutho, ukuphucula izinga lokuhamba kunye nohambo olusebenzayo, ukunciphisa ilahleko yoxinzelelo losasazo. Akukho sinyibilikisi kwi-coating, akukho nto i-exudate, ngoko ayiyi kungcolisa i-medium yokuhambisa, ukwenzela ukuba kuqinisekiswe ukucoceka kunye nococeko lolwelo, kuluhlu lwe-40 ℃ ukuya ku- +80 ℃ lunokusetyenziswa ngokutshintshanayo umjikelo oshushu kunye nokubanda, ungagugi, ungaqhekeki, ngoko unokusetyenziswa kwenye indawo ebandayo kunye nendawo ebandayo. Umbhobho wentsimbi odityanisiweyo omkhulu usetyenziswa kakhulu kumanzi ompompo, igesi yendalo, i-petroleum, ishishini lemichiza, amayeza, unxibelelwano, amandla ombane, ulwandle kunye namanye amasimi obunjineli.
