    I-ASTM A139 S235 J0 Amapayipi Ensimbi Evunguzayo

    I-ASTM A139 S235 J0 I-Spiral Steel Pipes Isithombe Esifakiwe
    • I-ASTM A139 S235 J0 Amapayipi Ensimbi Evunguzayo

    Incazelo emfushane:

    Sethula okusha kwethu kwakamuva kubuchwepheshe bamapayipi ensimbi - i-S235 J0 Spiral Steel Pipe.Lo mkhiqizo uklanywe kusetshenziswaI-ASTM A139 amazinga okuqinisekisa ukwakhiwa nokusebenza kwekhwalithi ephezulu.Inqubo yokwenza ipayipi lensimbi elivunguzayo elisetshenziswa ekukhiqizeni kwayo iqinisekisa ukuwohloka okufanayo kwepuleti lensimbi, ukucindezeleka okuncane okusalayo, kanye nendawo ebushelelezi ngaphandle kwemihuzuko.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Enye yezinzuzo eziyinhloko zeS235 J0 ipayipi lensimbi elivunguzayoukuguquguquka kwayo ngobubanzi kanye nokucaciswa kokuqina kodonga.Lokhu kuvumela ukuguquguquka okukhulu kokukhiqiza, ikakhulukazi ekukhiqizeni amapayipi asezingeni eliphezulu, anezindonga eziwugqinsi.Ngaphezu kwalokho, ubuchwepheshe busebenza kahle kakhulu ekukhiqizeni amapayipi anezindonga eziwugqinsi amadayamitha amancane naphakathi, adlula ezinye izindlela ezikhona.

    a.Indlela ye-deoxidation ikhethwe kanje:FF: Insimbi ebulawe ngokuphelele equkethe izakhi zokubopha i-nitrogen ngamanani anele ukuhlanganisa i-nitrogen etholakalayo (isb. imiz. 0,020 % ingqikithi ye-Al noma 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.

    Izimfanelo eziphakeme ze-S235 J0 spiral steel pipe ziyenza ilungele ukusetshenziswa okuhlukahlukene.Kungaba amaphrojekthi ezimboni, ezentengiso noma engqalasizinda, lo mkhiqizo uklanyelwe ukuhlangabezana nezidingo eziqinile zabasebenzisi bawo.Ukusebenza okuthembekile nokuqina kwayo kuyenza ibe yisixazululo esingabizi kakhulu kunoma iyiphi iphrojekthi edinga amashubhu e-arc angaphansi kwamanzi asondeziwe.

    X60 SSAW Line Pipe

    Ngaphezu kwe-S235 J0 spiral steel pipe, umugqa wethu womkhiqizo uhlanganisaIpayipi lensimbi i-A252 yeBanga lesi-3.Umkhiqizo ukhiqizwa kusetshenziswa ubuchwepheshe bakamuva bokukhiqiza obuqinisekisa ikhwalithi ephezulu kakhulu namazinga okuthembeka.Ngamandla alo aqinile okuqinile nokumelana nokugqwala okuhle kakhulu, ipayipi lensimbi i-A252 yeBanga lesi-3 lilungele ukusetshenziswa okufunwa kakhulu.

    Siyaziqhenya ngokunikela ngomugqa ogcwele wepayipi elishiselwe i-arc elihlanganisiwe elihlangabezana futhi elidlula izindinganiso zemboni.Ukuzinikela kwethu kukhwalithi kanye nokusungula izinto ezintsha kusenze saba umphakeli othembekile embonini yamapayipi ensimbi.Ngokuzibophezela ekusebenzeni kahle, siyaqhubeka nokuphusha imikhawulo yokukhiqiza amapayipi ensimbi.

    Uma kuziwa ku-spiral submerged arc welded pipe, imikhiqizo yethu ibeka izinga lokusebenza, ukuqina nokuthembeka.I-S235 J0 Spiral Steel Pipe kanye ne-A252 Grade 3 Steel Pipe yizibonelo ezimbili nje zokuzibophezela kwethu ekunikezeni amakhasimende ethu izixazululo ezingcono kakhulu.Sigxila eqophelweni eliphezulu nasekusungulweni kwezinto ezintsha futhi sizibophezele ekuhlangabezaneni nezidingo zamakhasimende ethu futhi sidlule lokho abekulindele.

    Kafushane, ipayipi lethu lensimbi elivunguzayo le-S235 J0 kanye nepayipi lensimbi le-A252 lebanga lesi-3 kuwumphumela wobuchwepheshe obusezingeni eliphezulu kanye nobuciko obusezingeni eliphezulu.Le mikhiqizo inikeza ukusebenza okungenakuqhathaniswa, okuyenza ibe ukukhetha okuphelele kwezinhlelo zokusebenza ezihlukahlukene.Kungakhathaliseki ukuthi ukwakhiwa, ingqalasizinda noma amaphrojekthi ezimboni, amapayipi ethu ashiselwe i-arc ahlanganisiwe adizayinelwe ukuletha imiphumela engcono kakhulu.Themba ukuthi ubuchwepheshe bethu nolwazi lwethu luzokunikeza amapayipi ensimbi ekhwalithi ephezulu kakhulu emakethe.
