Idayimitha enkulu umbhobho odityanisiweyo (isasa)luhlobo lombhobho olunoluhlu olubanzi lokusetyenziswa kwaye lunokusetyenziswa kwiindawo ezahlukeneyo kunye namashishini.Okulandelayo, makhe sijonge ngakumbi ukusetyenziswa kwemibhobho yentsimbi ejikelezayo enobubanzi obukhulu.

Okokuqala, imibhobho edityanisiweyo emikhulu ejikelezayo ingasetyenziswa njengemibhobho yamanzi.

Izixeko zoshishino kunye neendawo eziphuhliswe kwezolimo zifuna amanzi amaninzi ukuhlangabezana neemfuno zemveliso kunye neendawo zokuhlala, kunye nemibhobho yentsimbi ejikelezayo ineempawu zokumelana noxinzelelo, ukugoba ukugoba, ukumelana nobushushu obuphezulu, kunye nokumelana nomhlwa, okunokuqinisekisa ukhuseleko kunye nokuzinza kokunikezelwa kwamanzi. , ngoko ke zisetyenziselwa kakhulu ukuthutha Intsimi yokuvelisa amanzi kunye namanzi asekhaya.

Okwesibini, imibhobho edityanisiweyo ye-spiral enkulu ingasetyenziswa njengemibhobho yeoli.
Kwiminyaka yakutshanje, ngophuhliso loqoqosho lwehlabathi, imfuno kunye nemveliso ye-oyile kunye negesi yemithombo iyaqhubeka nokukhula, kwaye imibhobho yentsimbi ejikelezayo idlala indima ebaluleke kakhulu ekuthuthweni kwe-oyile negesi.Ukusetyenziswa kwemibhobho yentsimbi ejikelezayo enobubanzi obukhulu njengemibhobho yeoli ayinakuqinisekisa kuphela umgangatho kunye nokhuseleko lwemibhobho yeoli, kodwa nokunciphisa iindleko zokuyigcina kunye nobunzima.

Ukongeza, imibhobho edityanisiweyo enkulu ye-spiral ingasetyenziswa njengezinto zokwakha.
Kwintsimi yokwakha, imfuno yemarike nayo ikhula.Ngenxa yeempawu zamandla aphezulu, ukhuseleko kunye nokuthembeka, ukubethelwa kwesandi kunye nokushisa ukushisa, iipayipi zensimbi ezijikelezayo zisetyenziswa ngokubanzi kwizakhiwo zensimbi kunye nezakhiwo ezide kwintsimi yokwakha.

Umbhobho odityanisiweyo omkhulu wedayamitha engqukuva usenokusetyenziswa nakweminye imimandla yokusetyenziswa.Ngokomzekelo, izixhobo ezinkulu zepetrochemical, ifenitshala yezindlu eziphezulu, ukuveliswa kweemoto, iikhemikhali zesakhiwo sentsimbi kunye nenkxaso yobunjineli bakamasipala, njl.

Izinto eziluncedo zombhobho odityanisiweyo omkhulu ojikelezayo:

Amandla aphezulu: Umbhobho odityanisiweyo omkhulu wedayamitha ye-spiral unamandla aphezulu okuqina, amandla acinezelayo kunye nokumelana neempembelelo, kwaye ilungele iindawo ezahlukeneyo ezisingqongileyo.
Ukumelana ne-corrosion elungileyo: Itekhnoloji yonyango lomphezulu wombhobho wentsimbi (njengepeyinti yokuchasana ne-corrosion, i-epoxy resin coating, njl. njl.) inokuphucula ukuxhathisa ukubola kwemibhobho yentsimbi kunye nokwandisa ubomi babo benkonzo.
Ukugcina izixhobo kunye nokunciphisa iindleko: Inkqubo yokuvelisa i-diameter spiral steel pipes inokunciphisa ngokufanelekileyo ukusetyenziswa kwezinto kunye nokunciphisa iindleko zobunjineli.
Ukusebenza kokukhusela okusingqongileyo: Isixhobo sombhobho wensimbi sinokuphinda sisetyenziswe, esihambelana nombono wokukhusela okusingqongileyo okuluhlaza.
Ulwakhiwo olufanelekileyo: Umbhobho wensimbi ojikelezayo udibaniswe nge-welding, kwaye inkqubo yokwakha ilula kwaye ikhawuleza.

Izilumkiso zokuthenga imibhobho edityanisiweyo enedayamitha enkulu:

Amandla omenzi: Khetha umenzi wemibhobho yentsimbi edityanisiweyo enamandla aqinileyo kunye namava emveliso atyebileyo ukuqinisekisa umgangatho wemveliso othembekileyo.
Umgangatho wemveliso: Qonda izinto, amandla, ukuxhathisa ukubola kunye nezinye iipropathi zemibhobho yentsimbi, kwaye ukhethe iimveliso ezikumgangatho ophezulu ezihlangabezana neemfuno zobunjineli.
Ixabiso elifanelekileyo: Thelekisa iikowuteshini zabenzi abaninzi kwaye ukhethe iimveliso ezinexabiso eliphezulu lokusebenza.
Umgangatho wenkonzo: Qonda ukuthengisa kwangaphambili, ukuthengisa kunye neenkonzo emva kokuthengisa, kwaye ukhethe umenzi onokwaneliseka kwenkonzo ephezulu.
