    Sethula i-S235 J0 Spiral Steel Tube: Ikusasa Lobuqotho Besakhiwo


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Ezweni elihlala livela lokwakha nobunjiniyela, isidingo sezinto zokwakha zekhwalithi ephezulu eziqinisekisa ukuphepha, ukuqina, nokusebenza kahle sibalulekile.I-S235 J0 Spiral Steel Pipeiwumkhiqizo oguquguqukayo odizayinelwe ukuhlangabezana namazinga aqinile wezinhlelo zokusebenza zesimanje zesakhiwo. Lesi sixazululo esisha singaphezu nje kwepayipi; kuwubufakazi bobunjiniyela obuthuthukile nezinqubo zokukhiqiza ezibeka phambili amandla nokwethembeka.

    Amapayipi ensimbi e-S235 J0 akhiqizwa ngokuhambisana nezindinganiso zaseYurophu ezichaza izimo zokulethwa kwezobuchwepheshe zezingxenye ezingenalutho zesakhiwo ezishiselwe ezibandayo. Lokhu kusho ukuthi ipayipi ngalinye likhiqizwa kusetshenziswa inqubo ecophelelayo yokwenza amakhaza, iqinisekise ukuthi ubuqotho besakhiwo bugcinwa ngaphandle kwesidingo sokwelashwa kokushisa okulandelayo. Umkhiqizo wokugcina unezakhiwo ezinhle kakhulu zemishini, okwenza ube okahle ezinhlobonhlobo zezicelo zokwakha, ingqalasizinda kanye namaphrojekthi ezimboni.

    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 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 akumele kube ngaphezu kuka-12.5% ​​ngaphansi kogqinsi olushiwo

    I-S235 J0 Spiral Steel Pipe

     

    Esinye sezici ezivelele ze-S235 J0 Spiral Steel Tube wukuguquguquka kwayo. Itholakala ngamafomu ayindilinga, ayizikwele nangamanxande, umkhiqizo ungenziwa ngokwezifiso ukuze uvumelane nezidingo ezithile zanoma iyiphi iphrojekthi. Kungakhathaliseki ukuthi wakha uhlaka oluqinile lwesakhiwo sezentengiselwano, udala idizayini eyinkimbinkimbi yesici sezakhiwo, noma uthuthukisa ingqalasizinda ebalulekile njengamabhuloho namahubhe, i-S235 J0 Spiral Steel Tube inikeza ukuguquguquka namandla adingekayo ukuze ubone umbono wakho.

    Ukuqokwa kwe-S235 kukhombisa ukuthi ishubhu lenziwe ngensimbi yesakhiwo enokushisela okuhle kakhulu kanye nokusebenziseka kalula. Lokhu kubaluleke kakhulu kumaphrojekthi adinga ukunemba nokuhlanganiswa. Isijobelelo se-J0 sibonisa ukuthi okokusebenza kungamelana namazinga okushisa aphansi, okuyenza ifanelekele ukusetshenziswa ezindaweni ezinokhahlo lapho ukuguquka kwezinga lokushisa kungase kubangele ingozi ekuthembekeni kwesakhiwo. Le nhlanganisela yezakhiwo iqinisekisa ukuthi i-S235 J0 spiral steel tube ayithembeki kuphela, kodwa futhi iyakwazi ukumelana nezimo eziningi zesimo sezulu.

    Ngaphezu kwalokho, imvelo eyakhiwe ngokubanda yepayipi lensimbi elivunguzayo i-S235 J0 iyinika ukuqeda okuphezulu okuphezulu nokunemba kobukhulu. Lokhu kusho ukuthi ipayipi ingahlanganiswa kalula ezinhlelweni ezikhona ngaphandle kokuguqulwa okubanzi. Indawo ebushelelezi iphinde ithuthukise ubuhle bomkhiqizo wokugcina, ikwenze kube ukukhetha okuphezulu kubakhi bezakhiwo nabaklami abazisa ukusebenza nomthelela obonakalayo.

    amapayipi ensimbi okuvunguza

    Ngaphezu kwezinzuzo zayo zobuchwepheshe, i-S235 J0 spiral steel pipe nayo iyisinqumo esivumelana nemvelo. Inqubo yokukhiqiza inciphisa ukumosha nokusetshenziswa kwamandla, ngokuhambisana nenkambiso ekhulayo yokusimama embonini yezokwakha. Ngokukhetha lo mkhiqizo, awugcini nje ukutshala imali ngekhwalithi, kodwa futhi ufaka isandla ekusaseni eliluhlaza.

    Sekukonke, i-S235 J0 Spiral Steel Tube iyisixazululo esisezingeni eliphezulu esihlanganisa ngokuphelele amandla, ukuguquguquka nokusimama. Kungakhathaliseki ukuthi uqala iphrojekthi entsha yokwakha noma ufuna ukuthuthukisa isakhiwo esikhona, lo mkhiqizo uklanyelwe ukuhlangabezana futhi udlule okulindele. Ihambisana namazinga aseYurophu kanye nezici zokusebenza ezinhle kakhulu, i-S235 J0 Spiral Steel Tube iyisinqumo esifanelekile sonjiniyela, abadwebi bezakhiwo nabakhi abafuna okungcono kakhulu ezintweni zokwakha. Yamukela ikusasa lokwakha nge-S235 J0 Spiral Steel Tube – inhlanganisela yokuqamba izinto ezintsha nokwethembeka.
