    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.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Isingeniso:

    Isidingo esikhulayo samandla asebenzayo futhi athembekile sesiyinkinga ebalulekile kohulumeni nezimboni emhlabeni jikelele.Njengoba amapayipi egesi yemvelo eyimithambo yokuthutha igesi yemvelo, ukukhethwa kwempahla yamapayipi kubalulekile ukuze kuqinisekiswe ukutholakala kwamandla okungenamthungo nokusimeme.Kule bhulogi, sihlola ukuthi i-S355 JR spiral steel pipe, eyaziwa nangokuthiipayipi le-helical seam, iguqula ukwakhiwa kwamapayipi egesi yemvelo, ithuthukise ukuphepha, ukuqina kanye nokusebenza kahle kwezokuthutha.

    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.

    Ukuhlolwa kwe-Hydrostatic

    Ubude bepayipi ngalinye kufanele buhlolwe ngumenzi kumfutho we-hydrostatic ozokhiqiza odongeni lwamapayipi ingcindezi engekho ngaphansi kuka-60% wamandla esivuno amancane ashiwo ekamelweni lokushisa.Ingcindezi izonqunywa yi-equation elandelayo:
    P=2St/D

    Ukwehluka Okuvumelekile Kwesisindo Nobukhulu

    Ubude bepayipi ngalinye buzokalwa ngokwehlukana futhi isisindo salo angeke sihluke ngaphezu kuka-10% ngaphezulu noma u-5.5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo nesisindo salo ngobude beyunithi ngayinye.
    Idayamitha yangaphandle akumele ihluke ngaphezu kuka-±1% ukusuka kububanzi obukhethekile obushiwo bangaphandle
    Ukujiya kodonga kunoma iyiphi indawo akufanele kube ngaphezu kuka-12.5% ​​ngaphansi kogqinsi olushiwo

    I-Helical Welded Pipe

    1. Qonda i-S355 JR ipayipi lensimbi elivunguzayo:

    Ipayipi lensimbi ye-S355 JRyenziwe ngensimbi yezinga eliphezulu i-S355JR futhi iyipayipi lomthungo elivunguzayo elakhelwe ngokukhethekile ukwakhiwa kwamapayipi egesi.Isakhiwo se-spiral seam sinikeza ipayipi amandla amahle kakhulu nokuvumelana nezimo, okulenza libe lilungele ukudluliswa nokuthuthwa kwegesi yemvelo amabanga amade.Ukuqina kwayo kuqinisekisa ukumelana nezinto zangaphandle ezinjengokunyakaza komhlabathi, ukuzamazama komhlaba kanye nokugqwala kwenhlabathi, ngaleyo ndlela kuqinisekisa ukuphila isikhathi eside nobuqotho besimiso samapayipi egesi yemvelo.

    2. Ukuphepha kuqala:

    Ukuthembeka nokuphepha kwamapayipi egesi yemvelo kubalulekile enhlalakahleni yemiphakathi kanye nemvelo.Amandla aphakeme nokuqina kwepayipi lensimbi elivunguzayo le-S355 JR lidlala indima ebalulekile ekwehliseni ubungozi bokuvuza, ukuphuka kanye nezingozi ezilandelayo.Ngenxa yokwakhiwa kwalo komthungo othandelayo, ubuqotho besakhiwo sepayipi buhlala bunjalo ngisho nasezimweni eziyinselele noma izimo zezulu ezimbi kakhulu.Ukufaka leli payipi ohlelweni lwamapayipi egesi yemvelo kunciphisa kakhulu amandla ezingozi zemvelo futhi kuvumela ukugeleza okungaphazamiseki kwegesi yemvelo kubasebenzisi bokugcina.

    3. Ukuqina kwengqalasizinda esimeme:

    Ukuqina okuphakeme kwepayipi lensimbi elivunguzayo le-S355 JR kuqinisekisa ukuphila isikhathi eside kwengqalasizinda yepayipi lakho legesi, ukonga izindleko zokulungisa nokushintsha ngokuhamba kwesikhathi.Ipayipi lenziwe ngensimbi yezinga eliphezulu i-S355JR, enokumelana nokugqwala okuhle kakhulu, ukumelana nomthelela nokumelana nokugqoka.Lokhu kumelana kunciphisa ukulungiswa nokushintshwa, ngaleyo ndlela kunciphisa umthelela wemvelo jikelele kanye nokukhishwa kwekhabhoni okuhambisana nokugcinwa kwamapayipi nokwakhiwa kabusha.Umjikelezo wempilo owandisiwe wepayipi lensimbi elivunguzayo i-S355 JR unikela ngokuqondile ohlelweni lwamapayipi egesi oluzinzile futhi olunobungani nemvelo.

    4. Thuthukisa ukusebenza kahle kwezokuthutha:

    Ukusebenza kahle ekuthuthweni kwegesi yemvelo kubandakanya ukunciphisa ukulahleka kwamandla kanye nokukhulisa umthamo wokudlulisa.Isakhiwo esivunguzayo somthungo wepayipi lensimbi elivunguzayo le-S355 JR livumela ukugeleza komoya okubushelelezi, okungaguquki, kunciphise ukulahleka kokungqubuzana ngenkathi kukhulisa umthamo wokuthutha wepayipi.Ipayipi inendawo yangaphakathi efanayo eqinisekisa ukugeleza okuthuthukisiwe, ngaleyo ndlela kunciphise ukusetshenziswa kwamandla nokwandisa ukusebenza kahle.Ukwengeza, imvelo yepayipi engasindi yenza ukuphatha, ukuthuthwa nokufaka kulawuleke, konga isikhathi nezindleko ngesikhathi sokwakha.

    Isiphetho:

    Ukufaka ipayipi lensimbi elivunguzayo i-S355 JR ekwakhiweni kwepayipi legesi yemvelo kufakazelwe ukuthuthukisa ukusebenza kahle kwengqalasizinda.Amandla akhethekile wepayipi, ukuqina kanye nezici zokuphepha kusiza ukuhamba kahle kwegesi yemvelo, kunciphise ubungozi bezingozi, izingozi zemvelo kanye nezindleko zokuyilungisa.Ngokuthuthukisa ukusebenza kahle kwezokuthutha kanye nokunciphisa ukulahleka kwamandla, ipayipi lidlala indima ebalulekile ekuhlangabezaneni nesidingo esikhulayo samandla ngenkathi samukela izinqubo ezizinzile.Ukutshala imali ezixazululweni ezintsha ezifana ne-S355 JR spiral steel pipe kubalulekile kohulumeni, izimboni kanye nemiphakathi ukuze kuqinisekiswe ukutholakala kwamandla okuthembekile, okuphumelelayo nokuvula indlela yekusasa lamandla ahlanzekile.
