    Ukuqonda ukubaluleka kwezinqubo ezifanele ze-welding ze-welding ze-Spiral Steel esetshenziswe emigqeni yamanzi aphansi komhlaba

    Ukuqonda ukubaluleka kwezinqubo ezifanele ze-welding ze-welding ze-Spiral Steel esetshenziswe emigqeni yamanzi aphansi
    • Ukuqonda ukubaluleka kwezinqubo ezifanele ze-welding ze-welding ze-Spiral Steel esetshenziswe emigqeni yamanzi aphansi komhlaba

    Incazelo emfushane:

    Lapho ufaka imigqa yamanzi engaphansi komhlaba, ukusebenzisa ipayipi eliphakeme kakhulu kubalulekile ekuqinisekiseni ukuqina kokuphela kwesikhathi eside kanye nokumelana nezici zezemvelo. Uhlobo olulodwa lwepayipi elisetshenziselwa imigqa yamanzi angaphansi komhlaba ipayipi lensimbi. Kodwa-ke, ukusebenzisa amapayipi asezingeni eliphakeme akwanele ukuqinisekisa isikhathi eside samapayipi akho amanzi. Izinqubo ezifanele zokushiswa kwamapayipi zibalulekile ekuqinisekiseni ukuthi amapayipi ensimbi anamakhaza angamelana nezimo ezinzima ezingaphansi komhlaba futhi anikeze ukulethwa kwamanzi okuthembekile.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

     Amapayipi e-Spiral Spiralisetshenziswa kabanzi emapanini angamanzi angaphansi komhlaba ngenxa yamandla abo aphezulu kanye nekhono lokubekezelela ingcindezi yangaphandle. Amapayipi akhiqizwa kusuka kuma-coil-steel coil strips akha isimo esivulekile. Inqubo ye-Welding eluhlaza esetshenziselwa ukukhiqiza la mapayipi ihlinzeka ngobuqotho obuhle kakhulu besakhiwo, okwenza balungele izinhlelo ezingaphansi komhlaba.

    Qaphela:

    I-1.so iyatholakala ngamapayipi ensimbi kububanzi obungaphandle obungaphandle kanye nobukhulu bodonga ogama phakathi kosayizi babo obuseduze obhalwe etafuleni, kepha kusayinwe izingokhwele.

    2. Amadayimitha angaphandle angaphandle kubakaki etafuleni agcinwa amadayimitha.

    Enye yezinto ezibaluleke kakhulu zokusebenzisa insimbi eluhlazaipayipi lemigqa yamanzi engaphansi komhlabaizinqubo ezifanele ze-welding. I-Welding inqubo yokujoyina izingxenye ezimbili zensimbi ngokusebenzisa ukushisa nengcindezi. Ngamapayipi amanzi angaphansi komhlaba, ikhwalithi ye-welding ithinta ngqo ubuqotho kanye nokwethenjwa kwepayipi.

    -Yikho ngqoIzinqubo zePipe WeldingUkuze uthole ipayipi lensimbi ekwina kuhilela izinyathelo ezibucayi eziningana. Okokuqala, ingaphezulu lepayipi elizofakwa ku-welded kumele lihlanzeke futhi linamahhala kunoma yikuphi ukungcola okunjengokungcola, uwoyela, noma upende. Lokhu kuqinisekisa ukuthi iWeld iqinile futhi ingenakungcola okungahlehlisa amandla ayo.

    Ipayipi le-SSAW

    Okulandelayo, amapharamitha we-Welding anjengokufaka kokushisa, ijubane le-welding, kanye nenqubomgomo yenqubo kumele ilawulwe ngokucophelela ukuze kufinyelelwe ama-welds asezingeni eliphakeme. Kusetshenziswa izinto ezifanelekile ze-welding namasu kubalulekile ekuvikeleni iziphambeko ezinjenge-porusio, imifantu, noma ukuntuleka kokuhlanganiswa, okungahlehlisa ubuqotho be-weld.

    Ngaphezu kwalokho, ukulandelela okulungile kanye nezinqubo zokwelashwa okushisa ngemuva kokushisa zibalulekile ngepayipi lensimbi esetshenziswe emigqeni yamanzi angaphansi komhlaba. Ukucekelwa phansi okusiza ukwehlisa ubungozi bokuqhekeka futhi kuthuthukise ikhwalithi ye-weld ephelele, kanti ukwelashwa okushisa ngemuva kokushisa kunciphisa izingcindezi ezisele futhi kuqinisekise umfaniswano we-miscream kuyo yonke indawo ye-Weld.

    Ngaphezu kwalokho, ukusetshenziswa kobuchwepheshe obuthuthukile be-welding obufana nezinqubo ezenzakalelayo ze-welding kanye nokuhlolwa okungabhubhisi kungathuthukisa ikhwalithi nokwethenjwa kwe-welding. Ubuchwepheshe bobuchwepheshe busiza ekuqinisekiseni ukuthi amalunga ama-welded ahlangana namandla adingekayo kanye namazinga afanele ukuhlinzeka ngokuthula kwengqondo ngokusebenza kwesikhathi eside kwemigqa yamanzi angaphansi komhlaba.

    Ngamafuphi, izinqubo ezifanele zokushiswa kwamapayipi zibalulekile ekuqinisekiseni ubuqotho kanye nokuphila isikhathi eside kwepayipi lensimbi esetshenziswa emigqeni yamanzi aphansi komhlaba. Ngokulandela amapharamitha we-welding adingekayo, amasu nezindlela zokulawula ikhwalithi, ubungozi bokulimala kwe-welding nokwehluleka kungancishiswa kakhulu. Umphumela uwumugqa wamanzi othembekile futhi oqinile ongamelana novivinyo lwesikhathi futhi unikeze ngezinsizakalo zokulethwa kwamanzi eziphephile nezisebenzayo. Ngemigqa yamanzi engaphansi komhlaba, ukutshala imali ohlelweni olufanele lwe-welding kuyisinyathelo esibucayi ekuqinisekiseni ukuthembeka okuphelele kanye nokuphila isikhathi eside kwepayipi.
