    Izinzuzo zokubanda ezakhiwe ze-welded

    Izinzuzo zokubanda kwasungulwa isithombe esifakiwe
    • Izinzuzo zokubanda ezakhiwe ze-welded

    Incazelo emfushane:

    Lapho kwakhiwa izakhiwo nezakhiwo, ukukhetha kwezinto zokwakha kudlala indima ebalulekile ekuqinisekiseni ukuqina namandla omkhiqizo wokugcina. Into eyodwa ethandwa embonini yezokwakha yinsimbi eyakhayo eyakhiwe ngenhlamvu. Le mali entsha inikezela ngezinzuzo eziningi ezahlukahlukene, okwenza kube ukukhetha kokuqala kwamaphrojekthi amaningi wokwakha.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Insimbi ebandayo eyenziwe ikhiqizwa ngokugoba nokwakha amashidi ensimbi noma amakhoyili ekushiseni kwegumbi ngaphandle kokusebenzisa ukushisa. Inqubo ikhiqiza izinto eziqinile, ezihlala isikhathi eside kunensimbi evuthiwe. Le nsimbi eyakhiwe ebandayo inikezela ngezinzuzo ezimbalwa ezibalulekile lapho zihlanganiswe ndawonye ukwakha izakhi zesakhiwo.

    Enye yezinzuzo eziphambili zeukubanda kwakha ukwakheka kwe-welded Insimbi isilinganiso sayo esiphakeme sokuqina kwesisindo. Lokhu kusho ukuthi kunikeza amandla aphakeme ngenkathi silula, okwenza kube lula ukuphatha nokuhamba ngesikhathi sokwakha. Ngokwengeziwe, amandla aphezulu ensimbi ebandayo anika amandla ama-Slidender kanye nemiklamo yesakhiwo esisebenzayo esandisa isikhala futhi sinciphise ukusetshenziswa kwezinto ezibonakalayo.

    Enye inzuzo ebalulekile yensimbi eyakhelwe ebandayo ye-welded ukufana kwayo kanye nokuvumelana. Inqubo eyakha amakhaza iqinisekisa ukuthi lensimbi igcina izakhiwo zemishini ezingavumelani kuyo yonke impahla, okuholela ekusebenzeni okubonakalayo nokuthembekile. Lokhu kuvumelana kubalulekile ekuqinisekiseni ubuqotho kanye nokuphepha kokwakhiwa kokugcina.

    Ipayipi le-SSAW

    Ngaphezu kwamandla kanye nokuvumelana, amakhaza ahlelwe ama-welded ehleliwe anikela ngokunemba okunengqondo okuhle nokunemba. Inqubo yokwakha ebandayo ivumela ukubekezelelana okuqinile nokubumba okuqondile, ukuqinisekisa ukuthi izakhi zesakhiwo zilingana nomthungo ngaphandle komhlangano. Leli zinga lokunemba libalulekile ekufezekiseni umkhiqizo osezingeni eliphakeme, obonakalayo obonakalayo.

    Ngokwengeziwe, i-weldive ehleliwe ye-welded ehleliwe iyaguquguquka futhi ingenziwa ngokwezifiso ukufeza izidingo ezithile zephrojekthi. Kungabunjwa kalula futhi kwakhiwe ezinhlobonhlobo zemikhuba nokucushwa okuhlukahlukene, okuvumela ukwakhiwa kwemiklamo eyinkimbinkimbi yesakhiwo. Lokhu kuguqulwa kwenza kufanelekile ukuthola izicelo ezahlukahlukene ezivela ekwakhiweni kwezindawo zokuhlala ezikhungweni zezimboni.

    Ukusetshenziswa kwensimbi ebandayo eyakhiwe ngenhlamvu ye-welded nakho kunomthelela kwemikhuba yokwakha esimeme. Imvelo yayo engasindi inciphisa umthwalo ophelele ekwakhiweni nasekwesandleni kokusekelwa, okuholela ekugcinweni kwezindleko nezinzuzo zezemvelo. Ngokwengeziwe, ukuhlinzwa kwensimbi kwenza kube yikhetho enobungani bemvelo yamaphrojekthi wokwakha.

    Ngamafuphi, kusungulwe ama-weldical ensimbi amakhaza anikeziwe ahlinzeka ngezinzuzo eziningi ezenza kube yisinqumo esikhangayo samaphrojekthi wokwakha. Isilinganiso sayo esiphakeme-esindayo, ukungaguquguquki, ukunemba, ukuguquguquka, ukuguquguquka nokuqina kwenza kube yinto ebalulekile yokwakha izakhiwo eziqinile, ezisebenza kahle. Njengoba imboni yezokwakha iyaqhubeka nokuvela, kwasungulwa amakhaza enhlamvu ye-welded yensimbi ebalulekile ekubumbeni izakhiwo kanye nengqalasizinda yesikhathi esizayo.
