Ukubanda kwakha i-welded yomugqa wepayipi lomlilo

Kusungulwe amakhaza wesakhiwo se-welded somlilo wepayipi lomlilo

Incazelo emfushane:

Kuvunguza amapayipi we-welded welded kudlala indima ebalulekile ezimbonini ezahlukahlukene, ikakhulukazi ezakhiweni ezibandayo ezakhiwe kanye nomugqa wepayipi lomlilo. Lawa mapayipi enziwa ngokugoba imichilo yensimbi eqhubekayo abe bobunjwa ohlwini bese befaka izimbotshana ezivuthayo ukuze wakhe amapayipi amade aqhubekayo. Zisetshenziselwa kabanzi zokuhambisa uketshezi, amagesi nezinto zokwakha eziqinile, kanye nasezinhlelweni zezinhlelo zokusebenza nezimboni.

In kubanda ukwakheka kwesakhiwoIzicelo, i-Spiral Seam Welded Pipe ibalulekile ekwakheni izakhiwo eziqinile nezinokwethenjelwa. Lawa mapayipi ajwayele ukwenziwa ngensimbi esezingeni eliphakeme futhi angamelana nemithwalo esindayo, abenze balungele amabhuloho, izakhiwo namanye amaphrojekthi wengqalasizinda. Impahla yemishini

a. Indlela ye-deoxidation iqokwa kanjena:
I-FF: Insimbi ebulewe ngokuphelele equkethe izinto ezibophayo ze-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isib
b. Inani eliphakeme le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kukhombisa okuqukethwe okuphelele kwe-AL ye-AL ye-0,020% ngesilinganiso esingu-2: 1, noma uma kungenjalo ezinye izinto ezibophayo ze-N zikhona. Izinto ezibophayo ze-N-Bonding zizoqoshwa kudokhumenti lokuhlola.

Ngaphezu kwalokho, ekuvikelweni komliloamapayipi, ukusetshenziswa kwamapayipi we-weldies we-weldies abalulekile ukuqinisekisa ukuphepha nokwethenjwa kohlelo. Lawa mapayipi aklanyelwe ngokukhethekile ukubekezelela amazinga okushisa aphezulu nezingcindezi futhi alungele ukusetshenziswa ezinhlelweni zokuvikela umlilo. Ukwakhiwa kwe-Welded of Spiral Seam Pepe kuqinisekisa ukuthi kubufakazi obuvuzayo futhi kugcina ubuqotho obuhlelekile ngisho nangaphansi kwezimo ezimbi kakhulu, okwenza kube yingxenye ebalulekile yokuvikelwa komlilo kanye nezinhlelo zokucindezela umlilo.

Enye yezinzuzo eziphambili zeSpiral Seam welded Pipeukuguquguquka kwayo nokuvumelana nezimo ezinhlelweni ezahlukahlukene. Lawa mapayipi angenziwa kuma-diameter ahlukahlukene nobukhulu bokuhlangabezana nezidingo ezithile zephrojekthi. Ngaphezu kwalokho, bangahlanganiswa nezinto zokuvikela ukuthuthukisa ukumelana nokugqwala futhi bandise impilo yabo yenkonzo, ukuzenza balungele ukusetshenziswa ezindaweni ezahlukene kanye nemibandela.

Kuvunguza amapayipi we-welded anezinzuzo ezicacile uma kuziwa ekufakweni nasekunakekelweni. Bangasindi futhi bavumelana nezimo, benza ukuba kube lula ukuthutha nokuphatha, ukunciphisa isikhathi sokufaka nezindleko zabasebenzi. Ngokwengeziwe, ubude bawo obude, obuqhubekayo bunciphisa isidingo sokuxhuma okwengeziwe, ukunciphisa ubungozi bokuvuza kanye nokuqinisekisa uhlelo olusebenza kahle noluthembekile lwamapayipi.

Ekuphetheni, Kuvunguza ipayipi le-welded kuyinto ebalulekile kwingxenye ehlukahlukene yezimboni, ikakhulukazi ezakhiweni ezibandayo ezakhiwe futhiUmugqa wepayipi lomliloIzicelo. Ukwakhiwa kwalo okuhlala isikhathi eside, ukusebenza okuphezulu nokuvumelana nezimo kwenza kube yisinqumo sokuqala sonjiniyela, osonkontileka kanye nabaphathi bephrojekthi. Ukuthi kwakha izinhlaka eziqinile noma ukuklama izinhlelo zokuvikela umlilo eziphephile nezinokwethenjelwa, amapayipi we-welden we-welded ayisixazululo esisemqoka ezidingweni zengqalasizinda zesimanje kanye nemboni yanamuhla.
