Ukubaluleka Kwezinsimbi Zensimbi Tubur kuLine Line Construction

Ukubaluleka Kwezinsimbi Zensimbi Tubular Ekwakhiweni Kwezinkundla Zamanzini Zokwakha Isithombe

Incazelo emfushane:

Inqwaba yensimbi tubulaIzingxenye ezibucayi zokwakhiwa kwamapayipi wamanzi angaphansi komhlaba, ukuhlinzeka ukwesekwa okudingekayo nokuqina ukumelana nezinhlobonhlobo zezimo zemvelo nezemvelo. Kuvunguza ipayipi lelded, ikakhulukazi, sekuyikhetho elithandwayo ngenxa yokucaciswa kwalo okuyingqayizivele kanye nezinzuzo kuzinhlelo zokusebenza zomugqa wamanzi aphansi komhlaba.

Amathegi Omkhiqizo

Lapho kwakha imigqa yamanzi aphansi komhlaba, ukukhetha izinto ezibonakalayo kudlala indima ebalulekile ekuqinisekiseni ubuqotho kanye nokusebenza kahle kohlelo.Inqwaba yensimbi tubulas, ojwayele owaziwa ngokuthi amapayipi, asetshenziswa kabanzi ngenxa yamandla abo aphakeme, ukumelana nokugqwala kanye nokuguquguquka okuhlukahlukene. Kulokhu, amapayipi we-Weld Welded ayisinqumo esihle sokwakhiwa kwamanzi angaphansi komhlaba ngenxa yezincazelo nezinzuzo zazo ezithile.

Amapayipi we-welded we-welded akhiqizwa kusetshenziswa inqubo yokushiswa kwe-spiral seam welding, engakha i-Wheel eqhubekayo eqhubekayo ebude bepayipi. Lokhu ubuchwepheshe be-welding akugcini ngokuqinisekisa ukungaguquguquki kanye nekhwalithi ephezulu yama-welds, kepha futhi kukhiqiza amapayipi ngamawazi amakhulu kanye nezindonga eziwugqinsi, ezibenza balungele izimo ezinzima zokufakwa kwamanzi ngaphansi kwamanzi.

Enye yezincazelo ezibalulekile zepayipi e-Weldid Welded yikhono lokuthola ukunemba okukhulu nokuqondile okuqhathaniswa nepayipi elijwayelekile eliqondile. Lesi sici sibaluleke kakhulu ekwakhiweni komugqa wamanzi aphansi komhlaba, lapho ukuguquguquka okunembile kwamapayipi nokugeleza kwamanzi okufanayo kubalulekile ekusebenzeni kahle kohlelo. Ngaphezu kwalokho, indawo ebushelelezi yangaphakathi yamapayipi we-welded we-welded inciphisa izingxabano nokucindezela kwethonya, kusiza ukukhulisa ukusebenza kahle kwamanzi futhi kunciphise ukusetshenziswa kwamandla.

Ngaphezu kwalokho, ipayipi elivuthayo eluhlaza litholakala ezinhlobonhlobo zezinto zokwenziwa kanye nezingubo zokubopha ukufeza izidingo ezithile zemvelo nezisebenzayo. Ukusuka kwinsimbi ye-carbon kuya ku-alloy nensimbi engenasici, la mapayipi anikela ngokumelana okuhlukile ekugculiseni, ukusabela kwamakhemikhali kanye nokuxineka kwemishini, ukuqinisekisa ukuthembeka kwesikhathi eside kuzinhlelo zokusebenza zomugqa wamanzi aphansi komhlaba. Ngaphezu kwalokho, izigqoko zokuvikela ezifana ne-epoxy, i-polyethylene, ne-polyurethane zingasetshenziswa ukukhulisa ukuqina kanye nenkonzo yempilo yamapayipi afudumele, ikakhulukazi ezimweni zenhlabathi ezonakalisayo nasezinhlabathini.

Ngokuya ukufakwa, izinqwaba zensimbi ze-tubular, kufaka phakathi amapayipi we-spiral welded, zinezinzuzo ezibalulekile ekwakhiweni kwamapayipi angaphansi komhlaba. Amandla abo aphezulu okulanda nokubumba okuhlelekile kuvumela ukungcwatshwa okujulile nokusekelwa kwamamitha amanzi, ngisho nasenhlabathini eyinselele kanye nezimo zezwe lezomhlaba. Ngaphezu kwalokho, uhlobo olungasindi lwamapayipi ensimbi lusiza ukuphatha nokuhamba, ukunciphisa isikhathi sokufaka nezindleko. I-Wishina Welded Pipe ingaxhunyaniswa kalula kusetshenziswa ukucushwa okuhlukahlukene kokuhlanganisa, ukuhlinzeka ngesisombululo esiguquguqukayo nesisebenzayo samaphrojekthi welayini angaphansi komhlaba.

Ngamafuphi, ukusetshenziswa kwezinqwaba zensimbi yensimbi (ikakhulukazi amapayipi we-welded we-welded) kubalulekile ekwakhiweni okuphumelelayo kwamapayipi angaphansi komhlaba. Ngezincazelo zayo ezihlukile, kufaka phakathi ukunemba okuphezulu okuphezulu, ukumelana nokuqina nokuguquguquka kokufakwa, ipayipi elishajiwe linikeza inhlanganisela enhle kakhulu yamandla nokusebenza kobuqotho bepayipi lesikhathi eside. Njengoba isidingo sengqalasizinda yezamanzi ethembekile futhi esimeme siyaqhubeka nokukhula, ukubaluleka kokusebenzisa ikhwalithi ephezuluInqwaba yensimbi yensimbisEkukhiqizweni komugqa wamanzi aphansi komhlaba akunakweqiwa.
