I-arc welding iyindlela esetshenziswa kakhulu ekwenzeni amapayipi, ikakhulukazi ezindaweni ezifaka amanzi angaphansi komhlaba. Nokho, njenganoma iyiphi inqubo yezimboni, iza nesethi yayo yezinselelo. Kule bhulogi, sizohlola izinselele ezivamile okubhekwana nazo ngesikhathi sokushiselwa kwe-arc yamapayipi futhi sinikeze izixazululo ezisebenzayo zokuqinisekisa ukuthi umkhiqizo wekhwalithi ephezulu nohlala isikhathi eside uyakhiqizwa.
Ifektri yethu itholakala eCangzhou, esiFundazweni saseHebei futhi ibihamba phambili ekukhiqizeni amapayipi kusukela ngo-1993. Imboni yethu ihlanganisa indawo engamamitha-skwele angu-350,000 futhi inabasebenzi abangochwepheshe abangu-680. Siyaziqhenya ngokusebenzisa ubuchwepheshe bokushisela i-spiral submerged arc, obuqinisekisa izinga eliphezulu nokuqina kwemikhiqizo yethu. Lobu buchwepheshe besimanje buklanyelwe ukuhlangabezana nezindinganiso eziphakeme kakhulu zokuhlinzekwa kwamanzi angaphansi komhlaba, okwenza amapayipi ethu abe yisixazululo esinokwethenjelwa nesihlala isikhathi eside sezinhlelo zokusebenza ezihlukahlukene.
Izinselelo Ezivamile ze-ArcIpayipi elishiselwe
1. Ikhwalithi yokushisela engahambisani: Enye yezinkinga ezivame kakhulu ekushiseleni kwe-arc ukuzuza ikhwalithi yokushisela engaguquki. Ukwehluka kokokufaka ukushisa, isivinini sokuhamba, kanye ne-engeli ye-electrode kungase kubangele ukushisela okubuthakathaka noma okungaphelele.
Isixazululo: Ukusebenzisa izinyathelo eziqinile zokulawula ikhwalithi nokusebenzisa amasistimu wokushisela okuzenzakalelayo kungasiza ukugcina ukungaguquguquki. Ukuqeqeshwa okuvamile kwabashiseli ngezindlela ezihamba phambili nokusebenzisa ubuchwepheshe bokuqapha obuthuthukisiwe nakho kungathuthukisa ikhwalithi yokushisela.
2. Ukuguqulwa nokugoba: Ukushisa okukhiqizwa phakathi nenqubo yokushisela kungase kubangele ukugoba noma ukukhubazeka kwepayipi, okuholela ekungaqondiseni kahle kanye nokwehluleka okungenzeka ekufakeni isicelo.
Isixazululo: Ukushisa ipayipi ngaphambi kokushisela nokusebenzisa amasu okubamba afanele kunganciphisa ukuhlanekezela. Ukwengeza, ukusebenzisa amasu okushisela ama-multi-pass kungasiza ukusabalalisa ukushisa ngokulinganayo, kunciphise ubungozi bokungqubuzana.
3. I-Porosity ne-Inclusions: Ukuba khona kwamaphakethe omoya (i-porosity) noma izinto zangaphandle (okufakiwe) ku-weld kungaphazamisa ubuqotho bepayipi.
Isixazululo: Ukuqinisekisa indawo yokusebenza ehlanzekile nokusebenzisa izinto zokugcwalisa ezisezingeni eliphezulu kunganciphisa kakhulu ubungozi be-porosity nokufakwa. Ukuhlolwa njalo kwemishini yokushisela kanyeipayipi lokushisela i-arckubalulekile futhi ukugcina inhlanzeko.
4. Ukuqhekeka: Ngenxa yokupholisa okusheshayo noma amasu okushisela angafanele, ukuqhekeka kungase kwenzeke, okubangele ukwehluleka kwesakhiwo sepayipi.
Isixazululo: Ukulawula amazinga okupholisa nokusebenzisa amasu okushisa kuqala kungasiza ekuvimbeleni ukuqhekeka. Ngaphezu kwalokho, ukukhetha okokusebenza kokugcwalisa okufanele okufana nokokubalulekile kungathuthukisa ukumelana kwe-weld ekuqhekekeni.
5. Ukungena Okwanele: Ukungena okwanele kungabangela ukujoyina okubuthakathaka okungase kwehluleke ngaphansi kwengcindezi.
Isixazululo: Ukulungisa imingcele yokushisela efana ne-voltage kanye ne-current kungakhuphula ukujula kwe-weld. Ukuhlolwa okuphelele nokuhlolwa kwe-weld nakho kuzosiza ekuhlonzeni nasekulungiseni noma yiziphi izinkinga ngaphambi kokuba ipayipi liqale ukusebenza.
Ekuphetheni
Esikhungweni sethu saseCangzhou, siyakuqonda ukubaluleka kokunqoba lezi zinselelo ezivamile zokushisela i-arc ukukhiqiza ipayipi elihlangabezana namazinga aphezulu kakhulu ekhwalithi nokuqina. Ngokusebenzisa ubuchwepheshe be-spiral submerged arc welding obuthuthukisiwe, siqinisekisa ukuthi imikhiqizo yethu ayithembeki nje kuphela kodwa futhi iyakwazi ukuhlangabezana nezidingo zezinhlelo zokusebenza ezihlukahlukene, ikakhulukazi ezinhlelweni zokuhlinzeka ngamanzi angaphansi komhlaba.
Ngokubhekana ngqo nalezi zinselele nokusebenzisa izisombululo ezisebenzayo, singaqhubeka sinikeza amakhasimende ethu imikhiqizo eyikhwalithi ehambisana nesikhathi. Kungakhathaliseki ukuthi udinga amapayipi wokwakha, ingqalasizinda noma izicelo zezimboni, ukuzibophezela kwethu kukhwalithi kanye nokusungula izinto ezintsha kuqinisekisa ukuthi uthola isisombululo esingcono kakhulu sezidingo zakho.
