    Amapayipi Ensimbi Ejikelezayo e-ASTM A139 S235 J0

    Amapayipi Ensimbi Ejikelezayo e-ASTM A139 S235 J0 Isithombe Esivelele
    • Amapayipi Ensimbi Ejikelezayo e-ASTM A139 S235 J0

    Incazelo emfushane:

    Sethula ubuchwepheshe bethu bamuva bobuchwepheshe bamapayipi ensimbi - i-S235 J0 Spiral Steel Pipe. Lo mkhiqizo wenzelwe ukusebenzisaI-ASTM A139 amazinga okuqinisekisa ukwakhiwa nokusebenza kwekhwalithi ephezulu. Inqubo yokwakha ipayipi lensimbi elijikelezayo elisetshenziswa ekukhiqizweni kwalo iqinisekisa ukuguquguquka okufanayo kwepuleti lensimbi, ukucindezeleka okuncane okusele, kanye nobuso obubushelelezi obungenamihuzuko.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Enye yezinzuzo eziyinhloko ze-Ipayipi lensimbi elijikelezayo le-S235 J0ukuguquguquka kwayo ngobukhulu kanye nokucaciswa kobukhulu bodonga. Lokhu kuvumela ukukwazi ukukhiqiza ukuzivumelanisa nezimo okukhulu, ikakhulukazi ekukhiqizweni kwamapayipi aqinile, asezingeni eliphezulu. Ngaphezu kwalokho, ubuchwepheshe busebenza kahle kakhulu ekukhiqizeni amapayipi aqinile anobubanzi obuncane nobuphakathi, okwenza kube ngcono kunezinye izindlela ezikhona.

    a. Indlela yokususa i-oxidation ichazwa kanje: FF: Insimbi ebulewe ngokuphelele equkethe izinto zokubopha i-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isb. ubuncane be-0,020 % i-Al iyonke noma i-0,015 % i-Al encibilikayo).b. Inani eliphakeme le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa okuqukethwe okungenani kwe-Al iyonke okungu-0,020 % ngesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izinto zokubopha i-N ezanele. Izinto zokubopha i-N zizoqoshwa kuDokhumenti Yokuhlola.

    Izimfanelo ezinhle kakhulu zepayipi lensimbi elijikelezayo le-S235 J0 lenza libe yindawo ekahle kakhulu yezinhlelo zokusebenza ezahlukahlukene. Kungaba amaphrojekthi ezimboni, ezentengiselwano noma engqalasizinda, lo mkhiqizo wenzelwe ukuhlangabezana nezidingo eziqinile zabasebenzisi bawo. Ukusebenza kwawo okuthembekile nokuqina kwawo kwenza kube yisisombululo esingabizi kakhulu kunoma yimuphi umsebenzi odinga amashubhu e-arc acwiliswe ngaphakathi kwe-spiral.

    Ipayipi Lomugqa we-X60 SSAW

    Ngaphezu kwepayipi lensimbi elijikelezayo le-S235 J0, umugqa wethu womkhiqizo uhlanganisa futhiIpayipi lensimbi le-A252 lebanga lesi-3Lo mkhiqizo wenziwa kusetshenziswa ubuchwepheshe bamuva bokukhiqiza obuqinisekisa amazinga aphezulu kakhulu okuthembeka. Njengoba unamandla aphezulu okudonseka kanye nokumelana nokugqwala okuhle kakhulu, ipayipi lensimbi le-A252 Grade 3 lilungele ukusetshenziswa okudingakalayo.

    Siyaziqhenya ngokunikeza umugqa ogcwele wepayipi elihlanganisiwe elingaphansi kwe-spiral elihlangabezana futhi lidlula amazinga omkhakha. Ukuzinikela kwethu ekhwalithini nasekusunguleni izinto ezintsha kusenze saba umhlinzeki othembekile embonini yamapayipi ensimbi. Ngokuzibophezela ekwenzeni kahle, siyaqhubeka nokucindezela imikhawulo yokukhiqizwa kwamapayipi ensimbi.

    Uma kukhulunywa ngepayipi elihlanganisiwe elifakwe i-spiral arc, imikhiqizo yethu ibeka indinganiso yokusebenza, ukuqina kanye nokuthembeka. Ipayipi Lensimbi Eligobile le-S235 J0 kanye nepayipi Lensimbi Eligobile le-A252 Grade 3 ziyizibonelo ezimbili nje zokuzibophezela kwethu ekuhlinzekeni amakhasimende ethu ngezixazululo ezinhle kakhulu. Sigxila ekhwalithini nasekusunguleni izinto ezintsha futhi sizibophezele ekuhlangabezaneni nezidingo zamakhasimende ethu kanye nokwedlula lokho abakulindele.

    Ngamafuphi, ipayipi lethu lensimbi eliyindilinga le-S235 J0 kanye nepayipi lensimbi lebanga lesi-3 le-A252 liwumphumela wobuchwepheshe obusezingeni eliphezulu kanye nobuciko obuphezulu. Le mikhiqizo inikeza ukusebenza okungenakuqhathaniswa, okwenza kube ukukhetha okuhle kwezinhlelo zokusebenza ezahlukahlukene. Kungakhathaliseki ukuthi ukwakhiwa, ingqalasizinda noma amaphrojekthi ezimboni, amapayipi ethu ahlanganisiwe e-spiral ac welded aklanyelwe ukuletha imiphumela emihle kakhulu. Sithemba ukuthi ubuchwepheshe bethu kanye nolwazi lwethu kuzokunikeza amapayipi ensimbi asezingeni eliphezulu emakethe.
