Imibhobho yeNtsimbi eDityanisiweyo ene-Spiral
Imibhobho yentsimbi edityanisiweyo yeSpiral yenzelwe ngokukodwa ukuhlangabezana neemfuno ezahlukeneyo zamashishini ahlukeneyo kwaye isetyenziswa ngokubanzi kuthutho lweoyile negesi,ityhubhuulwakhiwo, iipali zeebhulorho kunye namanye amabala.Ubume bayo obukhethekileyo kunye nokusebenza okugqwesileyo kwenza kube yinto yokuqala yokukhetha izixhobo zemibhobho yendabuko, kunye neenzuzo ezizodwa eziphucula ukusebenza kwayo kunye nokusebenza kakuhle.
Enye yeenzuzo eziphambili zeumbhobho wentsimbi odityanisiweyokukusebenza kwayo iindleko.Xa kuthelekiswa nemibhobho yentsimbi engenamthungo, imibhobho yentsimbi edityanisiweyo inexabiso eliphantsi ukuvelisa ngaphandle kokuthomalalisa umgangatho.Oku kwenza ukuba imisebenzi ibe noqoqosho ngakumbi, iyenze ibe yinto efanelekileyo kwiiprojekthi ezifuna ubuninzi bepayipi yensimbi kwizicelo ezahlukeneyo.Ngokunciphisa iindleko, iinkampani zingakwazi ukwaba izibonelelo ngokufanelekileyo, okukhokelela ekugcinweni okubalulekileyo kuhlahlo lwabiwo-mali lweprojekthi.

Ukongeza, ukusebenza kakuhle kwemvelisoimibhobho yentsimbi ejikelezayoiphezulu kakhulu kunemibhobho yentsimbi engenamthungo.Ngombhobho ongenamthungo, inkqubo yokuvelisa ibandakanya ukukhupha i-billet yensimbi eyomeleleyo ngentonga enemingxuma, ekhokelela kwinkqubo yemveliso ecothayo nentsonkothileyo.Ngokwahlukileyo, umbhobho odityanisiweyo we-spiral unokuveliswa kwiidayamitha ezinkulu kunye nobude, okukhokelela kumaxesha amafutshane okuvelisa kunye nokwandisa ukusebenza kakuhle.Oku kuqinisekisa ukunikezelwa okuhambelanayo kweemibhobho ezikumgangatho ophezulu kwixesha elifutshane, okwenza kube isisombululo esithembekileyo kunye nesokugcina ixesha kumashishini ahlukeneyo.
Enye inzuzo ephawulekayo ye-spiral welded pipes kukumelana kwabo okugqwesileyo kuxinzelelo lwangaphandle kunye noxinzelelo lomatshini.I-Welds inika ukuqina okongeziweyo, ukuvumela le mibhobho ukuba imelane noxinzelelo oluphezulu kunemibhobho engenamthungo.Le propati ibaluleke kakhulu kwizicelo kwishishini leoli kunye negesi, apho imibhobho iphantsi koxinzelelo olubalulekileyo lwangaphakathi nangaphandle.Ngokusebenzisa imibhobho ye-spiral welded, iinkampani zinokuqinisekisa uthutho olukhuselekileyo nolusebenzayo lwezi zixhobo zibalulekileyo.
Ukongeza, ukuguquguquka kombhobho we-spiral welded kwenza ukuba ulungelelanise kakhulu kwiimfuno ezahlukeneyo zokwakha.Le mibhobho ingenziwa ngokwezifiso ukuhlangabezana neemfuno ezithile zeprojekthi, kubandakanywa ububanzi obuhlukeneyo, ubukhulu kunye nobude.Nokuba yeyofakelo lwemfumba yombhobho okanye iipali zebhulorho, imibhobho yentsimbi edityanisiweyo ibonelela ngezisombululo ezigqwesileyo kuzo zombini ezi zicelo zaselunxwemeni nakwi-offshore.Ubume bayo obuphezulu besakhiwo buqinisekisa ukusebenza okuhlala ixesha elide, ukunciphisa iindleko zokugcina kunye nokunciphisa imfuno yokutshintshwa kwangaphambili.
Ngokufutshane, i-spiral welded pipe izisa inguqu kwishishini lombhobho wentsimbi kunye nokusebenza kwayo okugqwesileyo kunye neenzuzo ezibalulekileyo.Ixabiso layo eliphezulu, ukusebenza kakuhle kwemveliso, ukumelana noxinzelelo kunye nokulungelelaniswa kwezicelo ezininzi kwenza kube yinto yokuqala yokukhetha ukuthutha ioli kunye negesi, ukwakhiwa kwemfumba yombhobho, i-bridge piers kunye nokunye.Ngomgangatho wayo ongenamthungo kunye ne-welded seams, le mveliso entsha ibonelela ngesisombululo esithembekileyo kunye nesigxina kumashishini kwihlabathi jikelele.Tyala imali kwi-spiral welded pipe kunye namava okusika ukuqhubela phambili kwitekhnoloji yombhobho wentsimbi.
