Ukuthuthukisa Ingqalasizinda Yemisele Yendle Ngokusebenzisa I-Spiral Submerged Arc Pipes (SSAW) Isithombe Esifakiwe

Incazelo emfushane:

Le ngxenye yaleli Zinga LaseYurophu icacisa izimo zobuchwepheshe zokulethwa kwesakhiwo esishiselwe ngendlela ebandayo, izingxenye ezingenalutho zamafomu ayindilinga, ayisikwele noma angunxande futhi isebenza ezingxenyeni ezingenalutho ezakhiwe ezibandayo ngaphandle kokwelashwa okushisayo okulandelayo.

I-Cangzhou Spiral Steel Pipes Group Co., Ltd ihlinzeka ngengxenye engenalutho yamafomu ayindilinga amapayipi ensimbi okwakhiwa.

Uhlolojikelele lwepayipi elishiselwe i-arc elishiselwe ngaphansi kwe-spiral:

Ipayipi le-arc elingaphansi kwe-spiral, ngokuvamile eyaziwa ngokuthi i-spiral submerged arc welded pipe, yakhiwa ngokugingqa insimbi egoqiwe eshisayo ibe yisimo esithandelayo bese siyishisela eduze komthungo wokushisela kusetshenziswa indlela yokushisela engaphansi kwe-arc.Lawa mapayipi ahlinzeka ngezinga eliphezulu lokuqina, amandla kanye nokumelana nokugqwala, okuwenza alungele amaphrojekthi engqalasizinda abalulekile njengamapayipi endle.

Izinzuzo zepayipi le-SSAW ekusetshenzisweni kwendle:

1. Ukuqina: Amapayipi ashiselwe i-arc angaphansi kwe-Spiral enziwe ngensimbi yezinga eliphezulu futhi anokuqina okuhle kakhulu.Banamandla okumelana nemithwalo esindayo kanye nezimo ezimbi kakhulu ezingaphansi komhlaba, ziqinisekisa impilo ende yesevisi yamapayipi endle.

2. Ukumelana nokugqwala: Inqubo yokwenza idiphu eshisayo ingeza ungqimba olwengeziwe lwesivikelo epayipini elishiselwe i-arc elingaphansi kwamanzi, okulenza likwazi ukumelana nokugqwala.Lesi sakhiwo sibalulekile kumasistimu endle ngoba avame ukuhlangana nendawo yamakhemikhali nebhayoloji enolaka.

3. Idizayini engavuzi: Ipayipi elishiselwe i-arc elingaphansi kwamanzi elisontekile lakhiwe kusetshenziswa inqubo yokushisela eqhubekayo ukuze kuqinisekiswe isakhiwo esingavuzi.Lesi sici sivimbela noma yikuphi ukungena noma ukuvuza, ngaleyo ndlela kuncishiswe amandla okungcoliswa komhlaba kanye nesidingo sokulungisa okubizayo.

4. Ukuguquguquka nokuzivumelanisa nezimo: Ipayipi elishiselwe i-arc elingaphansi kwe-Spiral lingakhiwa ukuze lilingane nobubanzi obuhlukahlukene, ubude nemithambeka, okuvumela ukuguquguquka okukhulu ekwakhiweni kwesistimu yendle.Bangakwazi ukuzivumelanisa kalula nokushintsha kwendawo kanye nendlela, baqinisekise ukugeleza kwamanzi angcolile ngisho nasezindleleni eziyinkimbinkimbi zendle.

5. Ukusebenza Kwezindleko: Uma kuqhathaniswa nezinto zamapayipi endle endabuko ezifana nokhonkolo noma ubumba, amapayipi ashiselwe i-arc angaphansi kwamanzi anganikeza ukonga kwezindleko ezibalulekile ekufakeni nasekulungiseni.Imvelo yabo engasindi inciphisa izindleko zokuthumela futhi kulula ukuyifaka, inciphisa izidingo zabasebenzi.Ukwengeza, impilo yayo yesevisi ende kanye nezidingo zokunakekelwa okuncane kunomthelela ekusebenzeni kwezindleko zesikhathi eside.

a.Indlela ye-deoxidation ikhethwe kanje: FF: Insimbi ebulawe ngokuphelele equkethe izakhi zokubopha i-nitrogen ngamanani anele ukuhlanganisa i-nitrogen etholakalayo (isb. min. 0,020 % isiyonke i-Al noma i-0,015 % e-soluble Al). b.Inani eliphakeme kakhulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa inani elincane eliphelele lokuqukethwe kwe-Al elingu-0,020 % elinesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izakhi ezanele zokubopha i-N.Izinto ezibophezela i-N zizorekhodwa kuMqulu Wokuhlola.

Izicelo zamapayipi e-SSAW kumasistimu endle:

1. Amanethiwekhi Kamasipala Okuthuthwa Kwendle: Amapayipi e-SSAW ajwayele ukusetshenziswa ekwakhiweni kwemigudu yendle emikhulu ehlinzeka izindawo zokuhlala, ezohwebo nezimboni.Amandla abo nokumelana nokugqwala kubenza babe ukukhetha okuhle kakhulu ukuthutha amanzi angcolile amabanga amade.

2. Ukukhipha amanzi esiphepho:Amapayipi e-SSAWingalawula ngempumelelo ukugeleza kwamanzi eziphepho futhi ivimbele izikhukhula ezindaweni zasemadolobheni.Ukuqina kwabo kuvumela ukudluliswa okuphumelelayo kwenani elikhulu lamanzi ekucindezelweni kwamanzi aphezulu.

3. Isikhungo sokuhlanza indle: Amapayipi ashiselwe yi-Spiral arc arc ashiselwe ekwakhiweni kwezingxenye ezihlukahlukene zesikhungo sokukhuculula indle, okuhlanganisa amapayipi okukhuculula indle, amathangi okungenisa umoya kanye nezinhlelo zokuhlanza udaka.Ukumelana kwawo namakhemikhali abolayo kanye nekhono lokusingatha izingcindezi ezihlukahlukene kuwenza abaluleke kakhulu ezindaweni ezinzima kangaka.

Ekuphetheni:

Ukukhetha impahla yamapayipi efanele kubalulekile ekwakhiweni ngempumelelo nasekunakekeleni isistimu yakho yendle.I-Spiral submerged arc pipe (SSAW) ifakazele ukuthi iyisixazululo esingabizi kakhulu, esiqinile futhi esisebenza ngezindlela eziningi.Ngokumelana nokugqwala okuhle kakhulu, ukuklama okungavuzi, kanye nokuvumelana nezimo ezihlukahlukene, amapayipi e-SSAW angakwazi ukuthutha amanzi angcolile ngendlela efanele, okunikela ekuthuthukisweni okusimeme kwamadolobha.Ukusetshenziswa kwamapayipi ashiselwe i-arc angaphansi kwe-spiral kumaphrojekthi endle kungavula indlela yokuthuthukisa amanethiwekhi endle ukuze kuhlangatshezwane nezidingo ezikhulayo zokuthuthukiswa kwedolobha.
