Ukuthuthukisa Ingqalasizinda Yendle Ukusebenzisa Amapayipi E-Arc Angaphansi Komoya (SSAW)

Incazelo emfushane:

Le ngxenye yale European Standard ichaza izimo zokulethwa kobuchwepheshe zezingxenye zesakhiwo ezihlanganisiwe ezibandayo, ezingenalutho zezinhlobo eziyindilinga, eziyisikwele noma eziyisikwele futhi isebenza ezingxenyeni zesakhiwo ezingenalutho ezakhiwe ezibandayo ngaphandle kokwelashwa kokushisa okulandelayo.

I-Cangzhou Spiral Steel Pipes Group Co., Ltd inikeza ingxenye engenalutho yamapayipi ensimbi ajikelezayo ukuze kwakhiwe.

Uhlelo lwendle olusebenza kahle lubalulekile ekukhuleni nasekuthuthukisweni kwanoma yiliphi idolobha. Ekwakhiweni nasekugcinweni kwezindawo zokulahla indleindleumugqas, ukukhetha amapayipi afanele kanye nezindlela zokufaka kubalulekile. Amapayipi e-arc angaphansi komhlaba ajikelezayo (i-SSAW) aseyisisombululo esithembeke kakhulu futhi esingabizi kakhulu sengqalasizinda yendle. Inhloso yale bhulogi ukukhanyisa izinzuzo kanye nokusetshenziswa kwamapayipi e-arc ahlanganisiwe angaphansi komhlaba ajikelezayo ekuthuthukiseni izinhlelo zendle.

Ukubuka konke kwepayipi elihlanganisiwe le-arc elingaphansi komhlaba elihlanganisiwe:

Ipayipi le-arc elicwiliswe ngaphansi kwe-Spiral, eyaziwa kakhulu ngokuthi ipayipi elihlanganisiwe le-arc elingaphansi komhlaba eliyi-spiral, lakhiwa ngokugoqa insimbi egoqiwe eshisayo ibe yisimo esijikelezayo bese uyihlanganisa ngomthungo wokuwelda kusetshenziswa indlela yokuwelda ye-arc engaphansi komhlaba. Lawa mapayipi anikeza izinga eliphezulu lokuqina, amandla kanye nokumelana nokugqwala, okwenza afaneleke kakhulu kumaphrojekthi engqalasizinda abalulekile njengemisele yamanzi angcolile.

Izinzuzo zamapayipi e-SSAW ekusetshenzisweni kwendle:

1. Ukuqina: Amapayipi ahlanganisiwe e-arc angaphansi komhlaba enziwe ngensimbi yekhwalithi ephezulu futhi aqinile kakhulu. Anamandla okubekezelela imithwalo esindayo kanye nezimo ezimbi kakhulu zangaphansi komhlaba, okuqinisekisa impilo ende yenkonzo yamapayipi endle.

2. Ukumelana nokugqwala: Inqubo yokugaya ngokushisa inezela ungqimba olwengeziwe lokuvikela epayipini elihlanganisiwe elingaphansi kwe-spiral, okwenza likwazi ukumelana nokugqwala kakhulu. Lesi sici sibalulekile ezinhlelweni zendle ngoba zivame ukuhlangana nezindawo ezinolaka zamakhemikhali nezebhayoloji.

3. Umklamo ovikela ukuvuza: Ipayipi elihlanganisiwe elingaphansi kwe-arc elihlanganisiwe eliqhutshwa nge-spiral lenziwa kusetshenziswa inqubo yokushisela eqhubekayo ukuqinisekisa isakhiwo esivikela ukuvuza. Lesi sici sivimbela noma yikuphi ukungena noma ukuvuza, ngaleyo ndlela sinciphise amathuba okungcoliswa komhlaba kanye nesidingo sokulungiswa okubizayo.

4. Ukuguquguquka kanye nokuzivumelanisa nezimo: Ipayipi elihlanganisiwe elingaphansi komhlaba elihlanganisiwe elihlanganisiwe lingenziwa ukuze lilingane nobubanzi obuhlukahlukene, ubude kanye nemithambeka, okuvumela ukuguquguquka okukhulu ekwakhiweni kwesistimu yendle. Zingazivumelanisa kalula nezinguquko endaweni kanye nesiqondiso, ukuqinisekisa ukugeleza kwamanzi amdaka kahle ngisho nasezinkundleni zendle eziyinkimbinkimbi.

5. Ukusebenza Kahle Ngezindleko: Uma kuqhathaniswa nezinto zepayipi lendle zendabuko ezifana nokhonkolo noma ubumba, amapayipi ahlanganisiwe e-arc acwiliswe ngaphansi kwe-spiral anganikeza ukonga okukhulu kwezindleko ekufakweni nasekugcinweni. Ukukhanya kwawo kunciphisa izindleko zokuthumela futhi kulula ukuwafaka, kunciphisa izidingo zabasebenzi. Ngaphezu kwalokho, impilo yawo yenkonzo ende kanye nezidingo zokunakekelwa okuncane kunegalelo ekusebenzeni kahle kwezindleko zesikhathi eside.

a. Indlela yokususa i-oxidation ichazwa kanje: FF: Insimbi ebulewe ngokuphelele equkethe izinto zokubopha i-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isb. ubuncane be-0,020% iyonke i-Al noma i-0,015% i-Al encibilikayo). b. Inani eliphezulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa okuqukethwe okungenani kwe-Al okungu-0,020% kanye nesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izinto ezibophayo ze-N ezanele. Izinto ezibophayo ze-N kufanele ziqoshwe kuDokhumenti Yokuhlola.

Ukusetshenziswa kwamapayipi e-SSAW ezinhlelweni zokuhambisa indle:

1. Amanethiwekhi Kamasipala Okuhambisa Indle: Amapayipi e-SSAW avame ukusetshenziswa ekwakhiweni kwemigqa emikhulu yokuhambisa indle ekhonza izindawo zokuhlala, zezentengiselwano kanye nezezimboni. Amandla awo kanye nokumelana nokugqwala kuwenza abe ukukhetha okuhle kakhulu kokuthutha amanzi angcolile amabanga amade.

2. Ukugeleza kwamanzi emvula:Amapayipi e-SSAWingaphatha kahle ukugeleza kwamanzi emvula futhi ivimbele izikhukhula ezindaweni zasemadolobheni. Ukuqina kwazo kuvumela ukudluliselwa kahle kwamanzi amaningi lapho kunengcindezi ephezulu yamanzi.

3. Isitshalo sokuhlanza indle: Amapayipi ahlanganisiwe angaphansi kwe-arc ahlanganiswe nge-spiral angasetshenziswa ekwakhiweni kwezingxenye ezahlukene zesitshalo sokuhlanza indle, okuhlanganisa amapayipi endle angahlanzwa, amathangi okungenisa umoya kanye nezinhlelo zokuhlanza udaka. Ukumelana kwawo namakhemikhali agqwalisayo kanye nekhono lokusingatha izingcindezi ezahlukahlukene kuwenza abaluleke kakhulu ezindaweni ezinjalo ezidinga kakhulu.

Ekuphetheni:

Ukukhetha izinto ezifanele zamapayipi kubalulekile ekwakhiweni nasekugcinweni kwesistimu yakho yokuhambisa amanzi angcolile ngempumelelo. Ipayipi le-arc elingaphansi komhlaba eliyi-Spiral submerged (SSAW) libonakalise liyisisombululo sengqalasizinda yendle engabizi kakhulu, eqinile futhi eguquguqukayo. Ngokumelana nokugqwala okuhle kakhulu, ukwakheka okungenawo amanzi avuzayo, kanye nokuzivumelanisa nezimo ezindaweni ezahlukene, amapayipi e-SSAW angathutha amanzi angcolile ngempumelelo, okunegalelo ekuthuthukisweni okusimeme kwamadolobha. Ukusetshenziswa kwamapayipi e-arc angaphansi komhlaba ahlanganisiwe kumaphrojekthi okuhambisa amanzi angcolile kungavula indlela yokuthi amanethiwekhi endle athuthukiswe ukuhlangabezana nezidingo ezikhulayo zentuthuko yasemadolobheni.
