Inzuzo Yenkampani

Le nkampani, etholakala enkabeni yeDolobha laseCangzhou, eSifundazweni saseHebei, ibilokhu ihola ekukhiqizweni kwamapayipi ahlanganisiwe selokhu yasungulwa ngo-1993. Lesi sitshalo simboza indawo engamamitha-skwele angu-350,000 futhi sihlonyiswe ngemishini nobuchwepheshe obuthuthukisiwe bokukhiqiza imikhiqizo yekilasi eliphezulu ehlangabezana nezindinganiso zomhlaba wonke. Njengoba inempahla elinganiselwa ku-RMB million 680 kanye nabasebenzi abanamakhono abangu-680, inkampani izibophezele ekwenzeni kahle kuzo zonke izici zokusebenza kwayo.

Isingeniso Somkhiqizo

Sethula ubuchwepheshe bethu bokushisela amapayipi obukhethekile obuthuthuke kakhulu, obuklanyelwe ngqo ukuhlangabezana nezidingo ezidingekayo zokushisela amapayipi egesi yemvelo. Okuhamba phambili kulobu buchwepheshe ubuchwepheshe bethu obuthuthukisiwe be-Submerged Arc Welding (SAW), indlela ekhethwayo yamapayipi ashiselwe nge-spirally. Lobu buchwepheshe buqinisekisa ukunemba, ukuqina kanye nokusebenza kahle, okwenza bufaneleke kakhulu ezimbonini ezithembele kumapayipi ashiselwe ekhwalithi ephezulu.

Ochwepheshe bethuukushisela amapayipiubuchwepheshe abugcini nje ngokuthuthukisa ubuqotho besakhiwo samapayipi egesi, kodwa futhi buthuthukisa inqubo yokushisela, bufinyeza isikhathi sokukhiqiza futhi bunciphise izindleko. Siyaqonda ukubaluleka kwezinhlelo zamapayipi egesi, futhi ukuzibophezela kwethu ekhwalithini kuqinisekisa ukuthi imikhiqizo yethu ingamelana nezidingo ezinzima zezicelo zayo ezihlosiwe.

Njengoba siqhubeka nokusungula nokuthuthukisa ubuchwepheshe bokushisela, sikumema ukuthi uzizwele ukuthembeka nokusebenza kobuchwepheshe bethu bokushisela amapayipi obuchwepheshile. Sithembe ukuthi sizokunikeza ipayipi elishiselwe elisezingeni eliphezulu elihlangabezana nezidingo zakho ezithile, elisekelwa ubuchwepheshe beminyaka eminingi kanye nokuzibophezela ekwanelisekeni kwamakhasimende.

Inzuzo Yomkhiqizo

1. Enye yezinzuzo eziyinhloko zokusebenzisa ukushisela kwe-arc engaphansi komhlaba ukushisela amapayipi egesi yemvelo yikhono layo lokukhiqiza ikhwalithi ephezuluukushintshwa kwepayipingezinkinga ezincane. Inqubo yokushisela i-arc ecwilisiwe ivumela ukungena okujulile kanye nezindawo ezibushelelezi, okubaluleke kakhulu ekuqinisekiseni ubuqotho bamapayipi egesi yemvelo.

2. Ukuzenzakalela kokushisela i-arc engaphansi komhlaba kungandisa umkhiqizo futhi kunciphise izindleko zabasebenzi kanye nesikhathi somsebenzi.

Ukushoda komkhiqizo

1. Inkinga eyodwa ebalulekile izindleko zokusetha zokuqala eziphakeme, ezingaba phezulu ngenxa yesidingo semishini ekhethekile kanye nabasebenzi abanamakhono.

2. Inqubo ayiguquguquki njengezinye izindlela zokushisela, okwenza ingafaneleki kangako kumajiyometri ayinkimbinkimbi noma izinto ezimbozwe ngodonga oluncane.

3. Lo mkhawulo ungadala izinselele kwezinye izinhlelo zokusebenza, okungase kuholele ekuhleleni amaphrojekthi amade.

Imibuzo Evame Ukubuzwa

Umbuzo 1. Kuyini Ukushisela I-Arc Engaphansi Komhlaba (i-SAW)?

I-SAW inqubo yokushisela esebenzisa i-electrode ephakelwa njalo kanye nesendlalelo se-granular fusible flux ukuvikela i-weld ekungcoleni. Le ndlela isebenza kahle kakhulu ezintweni ezijiyile futhi ifaneleka kahle kumapayipi egesi yemvelo.

Umbuzo 2. Kungani i-SAW ikhethwa kakhulu kumapayipi ahlanganisiwe ajikelezayo?

Ubuchwepheshe be-SAW buhlinzeka ngokungena okujulile kanye nobuso obubushelelezi, okubaluleke kakhulu ekuqineni kwesakhiwoipayipi elihlanganisiwe eliyindilingaisetshenziswa ezisetshenziswayo ezinomfutho ophezulu njengokuthuthwa kwegesi yemvelo.

Umbuzo 3. Yiziphi izinzuzo zokusebenzisa ubuchwepheshe bokushisela amapayipi obuchwepheshile?

Amasu akhethekile okushisela amashubhu aqinisekisa ikhwalithi ehambisanayo, anciphisa ubungozi bokukhubazeka futhi athuthukise ukusebenza kahle kwemikhiqizo eshiselwe, okubalulekile embonini ebaluleke kakhulu kwezokuphepha.

Umbuzo 4. Inkampani yakho iqinisekisa kanjani ikhwalithi yenqubo yokushisela?

Inkampani yethu ilandela izinyathelo eziqinile zokulawula ikhwalithi futhi isebenzisa ochwepheshe abanamakhono abaqeqeshwe ngamasu akamuva okushisela, okuhlanganisa ne-SAW, ukuqinisekisa ukuthi umkhiqizo ngamunye uhlangabezana nezindinganiso zokuphepha eziqinile kanye nokusebenza.
