    • Izinga Elijwayelekile Lepayipi Lensimbi le-Astm A139

    Incazelo emfushane:

    Kungakhathaliseki ukuthi udinga ipayipi lokwakha, uwoyela negesi, noma ezinye izinhlelo zokusebenza zezimboni, ipayipi lethu le-S235 J0 lenzelwe ukuhlangabezana nezindinganiso eziqinile zepayipi lensimbi le-ASTM A139 ukuqinisekisa ukuthembeka nokusebenza ngisho nasezindaweni ezidinga kakhulu.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Sethula ipayipi lensimbi eliyindilinga le-S235 J0 - ikhambi eliguquguqukayo elenzelwe ukuhlangabezana nezidingo ezahlukahlukene zemboni yanamuhla. Le nkampani yethu ikhiqizwe efektri yesimanje eseDolobheni laseCangzhou, eSifundazweni saseHebei, ibilokhu ihola ekukhiqizweni kwensimbi kusukela ngo-1993. Le nkampani ihlanganisa indawo engamamitha-skwele angu-350,000 futhi inempahla ephelele engu-RMB 680 million. Siyaziqhenya ngokuba nabasebenzi abazinikele abangochwepheshe abanamakhono abangu-680 abazinikele ekuhlinzekeni ngemikhiqizo esezingeni eliphezulu.

    Esinye sezici ezivelele zepayipi lensimbi elijikelezayo le-S235 J0 ukuguquguquka kwalo okuphawulekayo ngobukhulu kanye nokucaciswa kobukhulu bodonga. Lokhu kuvumelana nezimo kusenza sikwazi ukuhlangabezana nezidingo ezahlukene zokukhiqiza, ikakhulukazi ekukhiqizweni kwamapayipi anodonga oluqinile olusezingeni eliphezulu. Kungakhathaliseki ukuthi udinga ipayipi lokwakha, uwoyela negesi, noma ezinye izinhlelo zokusebenza zezimboni, ipayipi lethu le-S235 J0 lenzelwe ukuhlangabezana nezimfuneko eziqinile.I-ASTM A139amazinga epayipi lensimbi ukuqinisekisa ukuthembeka nokusebenza ngisho nasezindaweni ezidinga kakhulu.

    Ukuzibophezela kwethu ekhwalithini nasekusunguleni izinto ezintsha kusho ukuthi yonke ingxenye yepayipi lensimbi elijikelezayo le-S235 J0 idlula ezinqubweni zokuhlolwa okuqinile kanye nokulawulwa kwekhwalithi, ukuqinisekisa ukuthi umkhiqizo owutholayo awugcini nje ngokuhlangabezana nezindinganiso zomkhakha kodwa futhi udlula amazinga omkhakha. Ngolwazi lwethu olubanzi kanye nobuchwepheshe, sizibophezele ekuhlinzekeni amakhasimende ethu ngezixazululo ezinhle kakhulu ezenzelwe ukuhlangabezana nezidingo zawo ezithile.

    Inzuzo Yomkhiqizo

    1. Enye yezinzuzo eziyinhloko zepayipi lensimbi le-ASTM A139 ukuguquguquka kwalo ngobubanzi kanye nokucaciswa kobukhulu bodonga. Lokhu kuvumelana nezimo kuvumela abakhiqizi ukuthi bakhiqize amapayipi ngobukhulu obuhlukahlukene ukuze bahlangabezane nezidingo ezahlukene zephrojekthi.

    2. Amakhono okukhiqiza enkampani efana neyethu, etholakala eCangzhou, eSifundazweni saseHebei, athuthukisa izinzuzo ze-ASTM A139.

    3. Yasungulwa ngo-1993, ifektri yethu ihlanganisa indawo engamamitha-skwele angu-350,000, inempahla ephelele engu-RMB 680 million, futhi iqasha abasebenzi abanamakhono abangu-680. Le ngqalasizinda ebanzi isenza sikwazi ukuhlangabezana nezidingo zamakhasimende eziningi ngenkathi sigcina amazinga aphezulu okukhiqiza.

    Ukushoda komkhiqizo

    1. Izinga le-ASTM A139 kungenzeka lingahlanganisi zonke izidingo ezithile zezinhlelo zokusebenza ezithile, okuholela ekusebenzeni okulinganiselwe ngaphansi kwezimo ezimbi kakhulu.

    2. Inqubo yokukhiqiza ingaba yinkimbinkimbi kakhulu futhi ibize kakhulu kunezinye izindinganiso, okungase kuthinte amanani kanye nokutholakala.

    Umphumela

    Ipayipi Lensimbi Ejikelezayo le-S235 J0 liwusizo kakhulu kubakhiqizi ngenxa yokuzivumelanisa nezimo kwalo. Amandla okwenza ngokwezifiso ububanzi nobukhulu bodonga avumela ukukhiqizwa kwepayipi elisezingeni eliphezulu, elinodonga oluqinile elihlangabezana nezidingo ezithile zephrojekthi. Lokhu kuguquguquka akugcini nje ngokwandisa ukusebenza kahle kokukhiqiza, kodwa futhi kuqinisekisa ukuthi umkhiqizo wokugcina ungamelana nezimo ezahlukahlukene zemvelo kanye nezingcindezi, okwenza ufaneleke ezinhlelweni eziningi.

    Ifektri yethu itholakala eCangzhou, eSifundazweni saseHebei, futhi ibilokhu idlala indima ebalulekile embonini yensimbi selokhu yasungulwa ngo-1993. Ifektri yethu ihlanganisa indawo engamamitha-skwele angu-350,000, inempahla ephelele engu-RMB 680 million, futhi iqasha abasebenzi abanamakhono abangu-680. Le ngqalasizinda eqinile isenza sikwazi ukukhiqiza amapayipi ensimbi asezingeni eliphezulu ahlangabezana nezindinganiso ze-ASTM A139, okuqinisekisa ukuthi imikhiqizo yethu ihlangabezana nezidingo eziqinile zamakhasimende ethu.

    I-ASTM A139ipayipi lensimbiIzinga elijwayelekile linomthelela omkhulu ekukhiqizweni kwepayipi lensimbi elijikelezayo le-S235 J0, lithuthukisa ukuzivumelanisa nezimo kokukhiqiza kanye nekhwalithi yomkhiqizo. Njengoba siqhubeka nokuthuthukisa nokwandisa amakhono ethu, sisalokhu sizibophezele ekuhlinzekeni ngezixazululo zensimbi ezisezingeni eliphezulu ezihlangabezana nezidingo ezishintshayo zomkhakha.

    Imibuzo Evame Ukubuzwa

    Umbuzo 1: Kuyini i-ASTM A139?

    I-ASTM A139 iyincazelo ejwayelekile echaza izidingo zamapayipi ensimbi ashiselwe amelana nogesi. Lawa mapayipi avame ukusetshenziswa ekusetshenzisweni okuphansi komfutho futhi aziwa ngamandla awo nokuqina kwawo. Indinganiso iqinisekisa ukuthi amapayipi ahlangabezana nezakhiwo ezithile zemishini kanye nokwakheka kwamakhemikhali, okwenza afaneleke ukusetshenziswa okuhlukahlukene kwezimboni.

    Q2: Yiziphi izinzuzo zepayipi lensimbi elijikelezayo le-S235 J0?

    Enye yezinzuzo eziyinhloko zepayipi lensimbi elijikelezayo le-S235 J0 ukuguquguquka kwalo ngobukhulu kanye nokucaciswa kobukhulu bodonga. Lokhu kuvumelana nezimo kuvumela abakhiqizi ukuthi bakhiqize ipayipi elisezingeni eliphezulu, elinodonga olujiyile elingamelana nezingcindezi ezinkulu kanye nokucindezeleka. Ikhono lokwenza ngokwezifiso lezi zici lenza ipayipi le-S235 J0 libe ukukhetha okuhle kakhulu kumaphrojekthi adinga usayizi kanye namandla athile.
