Isishwankathelo sombhobho we-spiral arc welded ongaphantsi komhlaba:

Umbhobho we-arc ongaphantsi komhlaba ojikelezayo, eyaziwa ngokuba yi-spiral submerged arc welded pipe, yenziwa ngokuqengqa intsimbi eshushu egoqweyo ibe yimo ye-spiral kwaye iyidibanise kumthungo we-weld kusetyenziswa indlela ye-submerged arc welding. Le mibhobho inika izinga eliphezulu lokuqina, amandla kunye nokumelana nokugqwala, nto leyo eyenza ukuba ilungele iiprojekthi ezibalulekileyo zeziseko zophuhliso ezifana nemijelo yamanzi amdaka.

Iingenelo zepayipi ye-SSAW kwizicelo zomjelo wokuhambisa amanzi amdaka:

1. Ukuqina: Iipayipi ezifakwe kwi-arc ezifakwe kwi-spiral zenziwe ngentsimbi esemgangathweni ophezulu kwaye zihlala ixesha elide. Zinamandla okumelana nemithwalo enzima kunye neemeko ezinzima kakhulu phantsi komhlaba, ziqinisekisa ubomi benkonzo ende kwiipayipi ze-sewer.

2. Ukumelana nokugqwala: Inkqubo yokugaya i-hot-dip yongeza umaleko owongezelelweyo wokhuseleko kumbhobho odibeneyo we-arc welded ojikelezileyo, okwenza ukuba ungagqwali kakhulu. Olu phawu lubalulekile kwiinkqubo ze-sewer kuba zihlala zidibana neendawo ezinoburhalarhume zeekhemikhali kunye ne-biological.

3. Uyilo olungenako ukuvuza: Umbhobho ofakwe kwi-arc welded ojikelezileyo wenziwe kusetyenziswa inkqubo yokuwelda eqhubekayo ukuqinisekisa ukuba isakhiwo asinako ukuvuza. Olu phawu luthintela nakuphi na ukungena okanye ukuvuza, ngaloo ndlela kunciphisa amathuba okungcoliswa komhlaba kunye nesidingo sokulungiswa okubizayo.

4. Ukuguquguquka nokuguquguquka: Umbhobho odibeneyo we-arc ongaphantsi komhlaba unokwenziwa ukuze uvumelane nobubanzi obahlukeneyo, ubude kunye namathambeka, okuvumela ukuguquguquka okukhulu kuyilo lwenkqubo yemijelo yamanzi amdaka. Banokuzivumelanisa ngokulula notshintsho lomhlaba kunye necala, ukuqinisekisa ukuhamba kakuhle kwamanzi amdaka nakwiinethiwekhi zemijelo yamanzi amdaka ezintsonkothileyo.

5. UkuSebenza kakuhle kweendleko: Xa kuthelekiswa nezixhobo zemibhobho yendle yendabuko efana nekhonkrithi okanye udongwe, imibhobho edibeneyo ye-spiral submerged arc welded inokubonelela ngokonga okukhulu kweendleko ekufakweni nasekugcinweni kwayo. Ubunzima bayo bunciphisa iindleko zokuthunyelwa kwaye kulula ukuyifaka, nto leyo enciphisa iimfuno zabasebenzi. Ukongeza, ubomi bayo benkonzo ende kunye neemfuno ezincinci zokugcinwa kwayo zinegalelo ekusebenzeni kakuhle kweendleko ixesha elide.

a. Indlela yokususa ioksijini ichazwe ngolu hlobo lulandelayo: FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto zokubopha initrogen ngobuninzi obaneleyo ukubopha initrogen ekhoyo (umz. ubuncinci be-0,020% iyonke ye-Al okanye i-0,015% ye-Al enyibilikayo). b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukwakheka kweekhemikhali kubonisa umxholo opheleleyo we-Al ongama-0,020% kunye nomlinganiselo ophantsi we-Al/N oyi-2:1, okanye ukuba kukho ezinye izinto ezaneleyo zokubopha i-N. Izinto zokubopha i-N mazirekhodwe kuXwebhu loHlolo.

Ukusetyenziswa kwemibhobho ye-SSAW kwiinkqubo zogutyulo lwamanzi amdaka:

1. IiNethiwekhi zoGutyulo lweMfuyo zikaMasipala: Iipayipi ze-SSAW zisetyenziswa kakhulu ekwakhiweni kwemigca ephambili yogutyulo lwemfuyo enceda iindawo zokuhlala, zorhwebo kunye nemizi-mveliso. Amandla azo kunye nokumelana nokugqwala kuzenza zibe lukhetho oluhle kakhulu lokuthutha amanzi amdaka kumgama omde.

2. Ukukhupha amanzi emvula:Imibhobho ye-SSAWZiyakwazi ukulawula kakuhle ukugeleza kwamanzi emvula kwaye zithintele izikhukula kwiindawo zasezidolophini. Ukuqina kwazo kuvumela ukudluliselwa kwamanzi amaninzi ngokufanelekileyo xa kuxinezelekile kakhulu.

3. Isixhobo sokucocwa kwamanzi amdaka: Iipayipi ezifakwe i-arc welded ezijikelezileyo zingasetyenziswa ekwakheni iindawo ezahlukeneyo zesixhobo sokucocwa kwamanzi amdaka, kuquka iipayipi zamanzi amdaka ezingavuthwanga, iitanki zomoya kunye neenkqubo zokucocwa kodaka. Ukuxhathisa kwazo iikhemikhali ezibolayo kunye nokukwazi kwazo ukumelana noxinzelelo olwahlukeneyo kuzenza zibe yimfuneko kwiimeko ezinzima kangaka.

Ukuququmbela:

Ukukhetha izixhobo zombhobho ezifanelekileyo kubalulekile ekwakhiweni nasekugcinweni kwenkqubo yakho yokuhambisa amanzi amdaka ngempumelelo. Umbhobho we-arc ongaphantsi komhlaba (i-SSAW) ubonakalise ukuba sisisombululo seziseko zombhobho wokuhambisa amanzi amdaka esingabizi kakhulu, esihlala ixesha elide nesiguquguqukayo. Ngenxa yokumelana kwawo nokugqwala okugqwesileyo, uyilo olungenako ukuvuza, kunye nokuziqhelanisa neendawo ezahlukeneyo, imibhobho ye-SSAW inokuthutha amanzi amdaka ngokufanelekileyo, inegalelo kuphuhliso oluzinzileyo lwezixeko. Ukusetyenziswa kwemibhobho ye-arc ehlanganisiweyo engaphantsi komhlaba kwiiprojekthi zokuhambisa amanzi amdaka kunokuvula indlela yothungelwano oluphuculweyo lwemibhobho yokuhambisa amanzi amdaka ukuhlangabezana neemfuno ezikhulayo zophuhliso lwedolophu.
