    Isithombe Esijwayelekile Sepayipi Lensimbi le-Astm A139
    • I-Astm A139 Steel Pipe Standard

    Incazelo emfushane:

    Kungakhathaliseki ukuthi udinga ipayipi ukuze kwakhiwe, uwoyela negesi, noma ezinye izinhlelo zokusebenza zezimboni, ipayipi lethu le-S235 J0 lenziwe ukuthi lihlangabezane nezindinganiso eziqinile zepayipi lensimbi le-ASTM A139 ukuze kuqinisekiswe ukwethembeka nokusebenza ngisho nasezimweni ezinzima kakhulu.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Sethula ipayipi lensimbi elivunguzayo le-S235 J0 - isixazululo esisebenza ngezindlela eziningi esiklanyelwe ukuhlangabezana nezidingo ezihlukahlukene zemboni yesimanje. Ikhiqizwe efekthri esezingeni eliphezulu eseDolobheni laseCangzhou, eSifundazweni saseHebei, inkampani yethu ibihamba phambili ekukhiqizeni insimbi kusukela ngo-1993. Le nkampani ihlanganisa indawo engamamitha-skwele angu-350,000 futhi inempahla ephelele yezigidi ezingu-RMB 680. Siyaziqhenya ngokuba nabasebenzi abazinikele abangama-680 abaqeqeshiwe abazinikele ekuhlinzekeni ngemikhiqizo yekhwalithi ephezulu.

    Esinye sezici ezivelele ze-S235 J0 spiral steel pipe ukuguquguquka kwayo okuphawulekayo ububanzi kanye nokucaciswa kodonga. Lokhu kuvumelana nezimo kusivumela ukuba sihlangabezane nezidingo ezihlukahlukene zokukhiqiza, ikakhulukazi ekukhiqizeni amapayipi anezindonga eziwugqinsi esezingeni eliphezulu. Noma ngabe udinga ipayipi ukuze kwakhiwe, uwoyela negesi, noma ezinye izinhlelo zokusebenza zezimboni, ipayipi lethu le-S235 J0 lenziwe ngobunjiniyela ukuze lihlangabezane nezimo eziqinile.I-ASTM A139izindinganiso zamapayipi ensimbi ukuqinisekisa ukwethembeka nokusebenza ngisho nasezindaweni ezinzima kakhulu.

    Ukuzibophezela kwethu kukhwalithi nokuqamba okusha kusho ukuthi zonke izingxenye zepayipi lensimbi elivunguzayo le-S235 J0 lihlolwa kanzima kanye nezinqubo zokulawula ikhwalithi, siqinisekisa ukuthi umkhiqizo owutholayo awugcini nje ngokuhlangabezana kodwa udlula izindinganiso zomkhakha. Ngokuhlangenwe nakho kwethu okubanzi nobungcweti, sizibophezele ekunikezeni amakhasimende ethu izixazululo ezingcono kakhulu ezenzelwe ukuhlangabezana nezidingo zawo ezithile.

    a. Indlela ye-deoxidation iqokwe kanje:FF: Insimbi ebulawe ngokuphelele equkethe izakhi zokubopha i-nitrogen ngamanani anele ukuhlanganisa i-nitrogen etholakalayo (isb. min. 0,020 % isamba esingu-Al noma u-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.

     

     

    Inzuzo Yomkhiqizo

    1. Enye yezinzuzo eziyinhloko zepayipi lensimbi ye-ASTM A139 ukuguquguquka kwayo ububanzi kanye nokucaciswa kodonga. Lokhu kuvumelana nezimo kuvumela abakhiqizi ukuthi bakhiqize amapayipi ngobukhulu obuhlukahlukene ukuze bahlangabezane nezidingo ezihlukahlukene zephrojekthi.

    2. Amakhono okukhiqiza enkampani efana neyethu, eseCangzhou, esiFundazweni saseHebei, athuthukisa izinzuzo ze-ASTM A139.

    3. Yasungulwa ngo-1993, ifektri yethu ihlanganisa indawo engamamitha-skwele angu-350,000, inempahla ephelele yezigidi ezingu-RMB 680, futhi iqashe abasebenzi abanamakhono angu-680. Le ngqalasizinda ebanzi isenza sikwazi ukuhlangabezana nezinhlobonhlobo zezidingo zamakhasimende sibe sigcina amazinga aphezulu okukhiqiza.

    Ukushoda komkhiqizo

    1. Izinga le-ASTM A139 akumele lifake zonke izimfuneko ezithile zezinhlelo zokusebenza ezithile, okuholela ekusebenzeni okunamandla okunomkhawulo ngaphansi kwezimo ezibucayi.

    2. Inqubo yokukhiqiza ingase ibe yinkimbinkimbi futhi ibize kakhulu kunamanye amazinga, okungase kuthinte intengo nokutholakala.
