I-Tube Weld Ngokusebenza Okuthembekile

I-Tube Weld Ngesithombe Esifakiwe Esisebenza Okuthembekile

Incazelo emfushane:

Lobu buchwepheshe busebenzisa amazinga okushisa aphezulu ukuze kwakhe isibopho esiqinile nesiqinile phakathi kwamapayipi, ukuqinisekisa ukuthi imikhiqizo yethu inikeza ukusebenza okuthembekile ngisho nasezimweni eziyinselele kakhulu. Kungakhathaliseki ukuthi usembonini yegesi yemvelo noma udinga izixazululo ezithembekile zamapayipi kwezinye izinhlelo zokusebenza, amapayipi ethu azohlangabezana futhi adlule okulindele.

Inzuzo Yenkampani

Ifektri yethu itholakala eCangzhou, eSifundazweni saseHebei, futhi besihamba phambili ekukhiqizeni amapayipi ensimbi asezingeni eliphezulu kusukela sasungulwa ngo-1993. Imboni yethu ihlanganisa indawo engamamitha-skwele angu-350,000, enempahla ephelele yezigidi ezingu-RMB 680, ingakhiqiza amathani angu-400,000 amapayipi ensimbi okuvunguza anamakhono angu-680 ngonyaka, futhi inamakhono ochwepheshe abangama-680 ngonyaka.

Isingeniso Somkhiqizo

Ukuzibophezela kwethu ekwenzeni okuhle kubonakala enqubweni yethu ecophelelayo yokushisela i-arc, okuyisinyathelo esibalulekile ekwakhiweni kwepayipi lethu elishiselwe eligobile. Lobu buchwepheshe busebenzisa amazinga okushisa aphezulu ukuze kwakhe isibopho esiqinile nesiqinile phakathi kwamapayipi, ukuqinisekisa ukuthi imikhiqizo yethu inikeza ukusebenza okuthembekile ngisho nasezimweni eziyinselele kakhulu. Kungakhathaliseki ukuthi usembonini yegesi yemvelo noma udinga izixazululo ezithembekile zamapayipi kwezinye izinhlelo zokusebenza, amapayipi ethu azohlangabezana futhi adlule okulindele.

Ngokugxila kwikhwalithi nokuqanjwa okusha, siyaziqhenya ngokuhlinzeka ngokushisela amapayipi okuqinisekisa ukusebenza okuhlala isikhathi eside. Akuzona ezethu kuphelaipayipi elihlanganisiwe elivunguzayoziqinile futhi zihlala isikhathi eside, nazo zisebenza kahle kakhulu, zizenza zilungele amaphrojekthi adinga ukwethembeka nokuqina.

Isici esiyinhloko

Esinye sezici ezibalulekile zokushisela amashubhu ukuthembela ekushiseleni i-arc, inqubo esebenzisa amazinga okushisa aphezulu ukuze kwakhe ukuxhumana okuqinile, okuhlala isikhathi eside phakathi kwamashubhu ensimbi. Inqubo ibalulekile ekuqinisekiseni ubuqotho nokuthembeka komkhiqizo wokugcina, ikakhulukazi ezinhlelweni lapho ukuphepha nokusebenza kubaluleke kakhulu, njengokuthuthwa kwegesi yemvelo.

Inqubo ye-arc welding ihilela ukuncibilika emaphethelweni epayipi futhi uwahlanganise ndawonye, ukwakha uxhumano olungenasici olungamelana nokucindezela okuphezulu nezimo ezimbi kakhulu. Le ndlela ayigcini nje ukwandisa amandla ombhobho, kodwa futhi yandisa impilo yayo yenkonzo, okwenza kube ukukhetha okuthandwayo kwezicelo ezihlukahlukene zezimboni.

Ngaphezu kwalokho, ukunemba kanye nobuchwepheshe obudingekayo ekushiseleni amapayipi nakho kukhombisa ukuzibophezela kwenkampani kwikhwalithi. Ngokutshala imali kubuchwepheshe obuthuthukisiwe kanye nabasebenzi abanamakhono, imboni yaseCangzhou iqinisekisa ukuthi wonke amapayipi ashiselwe okuvunguzayo ahlangabezana nezindinganiso eziqinile zezimboni, okunikeza amakhasimende ukuthula kwengqondo nokuzethemba emkhiqizweni.

Inzuzo Yomkhiqizo

Enye yezinzuzo ezibalulekile ze-tube welding yikhono layo lokukhiqiza amalunga aqinile angakwazi ukumelana nezingcindezi eziphezulu kanye nezimo ezimbi kakhulu. Lokhu kubaluleke kakhulu embonini yegesi yemvelo, lapho ubuqotho bepayipi bubaluleke kakhulu. Inqubo ye-arc welding iqinisekisa ukuthitube weldayinamandla nje kuphela kodwa futhi ayiguquki, okunciphisa ingozi yokuvuza nokwehluleka. Ngaphezu kwalokho, ukusebenza kahle kwe-tube welding kuvumela abakhiqizi ukuthi bakhiqize ngokushesha inqwaba yamapayipi ensimbi okuvunguza ukuze kuhlangatshezwane nesidingo esikhulayo semakethe.

Ukushoda Komkhiqizo

Inqubo idinga abasebenzi abanamakhono kanye nokulawulwa okunembile kwamapharamitha wokushisela ukuze kugwenywe amaphutha afana ne-porosity noma ukuntuleka kokuhlanganisa. Lezi zinkinga zingalimaza ikhwalithi yomkhiqizo wokugcina futhi ziholele ezingozini zokuphepha ezingaba khona.

Ukwengeza, izinga lokushisa eliphezulu lokushisela kwe-arc lingakwazi ukwethula izingcindezi ezisele ezintweni, ezingathinta ukusebenza kwesikhathi eside kwepayipi.

FAQS

Q1: Iyini i-arc welding?

I-arc welding yindlela esebenzisa amazinga okushisa aphezulu akhiqizwa i-arc kagesi ukuze incibilike futhi ihlanganise amashidi ensimbi ndawonye. Ku-spiral welded pipe, le ndlela ibalulekile ukudala uxhumano oluqinile phakathi kwamapayipi, okubalulekile ekusebenzeni nokuphila kwepayipi.

Q2:Kungani i-arc welding ibalulekile kumapayipi egesi yemvelo?

Amapayipi egesi yemvelo kufanele ahlangabezane nezindinganiso eziqinile zokuphepha nokwethembeka. Inqubo yokushisela i-arc iqinisekisa ukuthi amajoyinti e-weld angakwazi ukumelana nezingcindezi eziphezulu futhi amelane nokugqwala, okwenza kube ekahle ukuthutha igesi yemvelo amabanga amade.
