Yethula:

Emkhakheni wobunjiniyela bezinhlekelele, ukubaluleka kokusebenzisa izinto zekhwalithi kanye nezindlela zokwakha akunakweqiwa. Phakathi kwezinto ezahlukahlukene ezisetshenziswa emisebenzini yokwakha, amapayipi adlala indima ebalulekile. Sizosikhanyisela ngokubaluleka kwamapayipi anamaphilisi aphindwe kabili futhi sihlole izici zabo, izinzuzo nokuthi zingasiza kanjani ukuthuthukisa ubuqotho bezinhlekelele.

Funda ngamapayipi ahlanganisiwe aphindwe kabili:

Ipayipi eliphindwe kabili, elaziwa nangokuthi ipayipi elifakwe kabili le-arcAmapayipi we-Dsaw), akhiqizwa esebenzisa inqubo ye-welding engaphansi ye-arc. Ubuchwepheshe bubandakanya ukufakwa amapuleti amade amakhafula amade ahlukene, ukuhlinzeka ngokuxhumana okuqinile nokuqhubekayo. Lawa mapayipi asetshenziswa ngokuyinhloko kwizicelo eziphakeme kakhulu, amanzi asemhlabathini kanye namapayipi egesi yemvelo, ukuhlola uwoyela, kanye namapulatifomu asogwini.

Ngcono ubuqotho besakhiwo:

Isizathu esibalulekile sokusebenzisaIpayipi eliphindwe kabiliamandla abo okuthuthukisa ubuqotho besakhiwo. Ngama-welds angenamthungo naqinile, la mapayipi anikela ngokumelana nokuxineka okuphezulu nokuqina. I-Weld ephindwe kabili iqinisekisa ukuthi ipayipi lingamelana namazinga aphezulu wengcindezi, okwenza lilungele izinhlelo zokusebenza ezibucayi lapho i-weld eyodwa ingahlekisa ngokuphepha okuhlelekile. Le nqubo ye-welding embaxambili isusa amathuba okuvuza noma ukuqhekeka, ukuqinisekisa ukuthembeka kwesikhathi eside kohlelo lwakho lwamapayipi.

Amandla aphezulu ekulinganiseni isisindo:

Ipayipi eline-welded kabili linikeza amandla amahle kakhulu ekulinganiseni isisindo. Ngenxa yenqubo ye-welding, la mapayipi anciphise ubukhulu odongeni futhi alula ngenkathi egcina ukuqina kwesakhiwo. Lesi simo se-Action-to-Weight

Ukumelana nokugqwala:

Enye inzuzo ebalulekile yepayipi eline-welded ephindwe kabili ukumelana nokuphikiswa kwayo. Useti oqinile we-welded kwakha isithiyo esiqinile ngokumelene nezinto zangaphandle, kufaka phakathi umswakama, amakhemikhali kanye nezakhiwo zenhlabathi. Lokhu kuvimbela ubuso bangaphakathi kwepayipi ukuthi bakwazi ukuxhumana ngqo nama-ejenti asolisayo, baqinisekise impilo ende yenkonzo ngokuqhathaniswa namapayipi ajwayelekile. Izakhiwo ezilwa nokugqwala kwalawa mapayipi zinzuzo ikakhulukazi embonini kawoyela negesi, lapho amapayipi avame ukubhekana nezimo ezinzima.

Izici zethrafikhi ezisebenzayo:

Indawo ebushelelezi, engaphazanyiswanga yangaphakathi yepayipi eline-welded ephindwe kabili livumela izici zokugeleza ezisebenzayo. Ngokungafani nezinye izinhlobo zamapayipi anama-protorions angaphakathi noma izithiyo, la mapayipi aqinisekisa ukuqhubeka nokugeleza koketshezi noma igesi, ngaleyo ndlela anciphise ukulahleka kwezingqubuzana. Izici zokugeleza ezisebenzayo zepayipi elinezinwele eziphindwe kabili zisiza ukusebenza kwezindlela ezahlukahlukene zezimboni, kufaka phakathi izitshalo ze-petrochemical, ama-conferies kanye nezindawo zokwelashwa kwamanzi.

Ekuphetheni:

Ekuphetheni, ipayipi elishawe kabili le-welded yingxenye ebalulekile ethuthukisa kakhulu ubuqotho bezinhlekelele zamaphrojekthi ahlukahlukene okwakha. Izakhiwo zazo ezihlukile, kufaka phakathi ama-welds angenamthungo, isilinganiso esiphakeme-esindayo, ukumelana nokugqwala nokugeleza okusebenzayo, kubenze bakhethwe ngokufanele, ukuqina kokuqala kwezicelo ezidinga ukuthembeka, ukuqina kanye nokusebenza kwezindleko. Ngokusebenzisa ipayipi elinezinwele eziphindwe kabili, onjiniyela kanye nosonkontileka bangaqinisekisa ukusebenza okuhlala isikhathi eside nokuphephile kwengqalasizinda ebucayi, okwenza kube yimpahla ebalulekile emasimini ezokwakha kanye nobunjiniyela.
