    I-ASTM A139 I-Steel Pipeard Standard Okufakiwe
    • I-ASTM A139 Steel Pipe ejwayelekile

    Incazelo emfushane:

    Ukuthi udinga ipayipi lokwakha, i-oyili negesi, noma ezinye izinhlelo zokusebenza zezimboni, ipayipi lethu le-S235 J0 lizohlangana nezindinganiso ze-a139 zensimbi ukuqinisekisa ukuthembeka nokusebenza ezindaweni ezifunwa kakhulu.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Kwethulwa ipayipi le-S235 J0 Spiral Pipe - Isixazululo esiguquguqukayo senzelwe ukufeza izidingo ezahlukahlukene zemboni yanamuhla. Kukhiqizwe efektri yombuso etholakala eCangegzhou City, esiFundazweni seHebei, inkampani yethu ibingumholi ukukhiqizwa kwensimbi kusukela ngo-1993. Inkampani ihlanganisa indawo engamamitha-skwele angama-350,000 wezigidi ezingama-RMB 680 million . Siyaziqhenya ngokuba nabasebenzi abazinikele kochwepheshe abanamakhono angama-680 abazinikezele ekuhlinzekeni imikhiqizo esezingeni eliphakeme.

    Enye yezinto ezivelele ze-S235 J0 Spiral Pipe iyindlela evumelana nezimo zayo eziphawuleka ngobubanzi kanye nokucaciswa kodonga. Lokhu kuvumelana nezimo kusivumela ukuthi sihlangane nezidingo ezahlukahlukene zokukhiqiza, ikakhulukazi ekukhiqizweni kwamapayipi abingelwa yibanga eliphakeme. Ukuthi udinga ipayipi lokwakha, i-oyili negesi, noma ezinye izinhlelo zokusebenza zezimboni, ipayipi lethu le-S235 J0 linezobuciko ukuze lihlanganeI-ASTM A139Izindinganiso ze-Steel Amazinga okuqinisekisa ukuthembeka nokusebenza ezindaweni ezifuna kakhulu.

    Ukuzibophezela kwethu kwekhwalithi kanye nokwenza izinto ezintsha kusho zonke iziqeshana zepayipi eliqinile le-S235 jpb Ngolwazi lwethu olunzulu nobuchwepheshe, sizibophezele ekuhlinzekeni amakhasimende ethu ngezixazululo ezinhle kakhulu ezihambisana nezidingo zazo ezithile.

    Inzuzo yomkhiqizo

    1. Enye yezinzuzo eziphambili ze-ASTM A139 Ipayipi yensimbi iguquguquka yayo ngobubanzi kanye nokucaciswa kodonga. Lokhu kuvumelana nezimo kuvumela abakhiqizi ukuthi bakhiqize amapayipi ngosayizi abahlukahlukene ukuze bahlangabezane nezidingo ezahlukahlukene zephrojekthi.

    I-3. Isungulwe ngo-1993, ifektri yethu ihlanganisa indawo yamamitha-skwele angama-350,000, inempahla ephelele ye-RMB 680 million, futhi isebenzisa abasebenzi abanamakhono angama-680. Le ngqalasizinda ebanzi isenza sikwazi ukufeza izidingo zamakhasimende ahlukahlukene ngenkathi sigcina amazinga aphezulu okukhiqiza.

    Ukushiyeka komkhiqizo

    1. I-ASTM A139 ejwayelekile kungenzeka ingahlanganisi zonke izidingo ezithile zohlelo oluthile, okuholele ekusebenzeni okungase kube khona ngaphansi kwezimo ezimbi kakhulu.

    2. Inqubo yokukhiqiza ingahle ibe yinkimbinkimbi futhi ibize kakhulu kunamanye amaZinga, angathinta amanani entengo nokutholakala.

    Umphumela

    I-S235 J0 Spiral Steel Pipe inenzuzo ikakhulukazi kubakhiqizi ngenxa yokuvumelana kwayo. Amandla okwenza ngezifiso ama-diameters kanye nobukhulu bodonga kuvumela ukukhiqizwa kweprimiyamu, ipayipi elibikwe ngodonga oluhlangene oluhlangabezana nezidingo ezithile zephrojekthi. Lokhu kuguquguquka akugcini nje njengokukhulisa ukusebenza kahle kokukhiqiza, kepha futhi kuqinisekisa ukuthi umkhiqizo wokugcina ungamelana nezimo ezahlukahlukene zezemvelo kanye nezingcindezi, okwenza kufanele kube lusizo olunhlobonhlobo lwezicelo.

    Ifektri yethu itholakala esifundazweni saseCangzhou, Hebei, futhi kube ngumdlali osemqoka embonini yensimbi selokhu yasungulwa ngo-1993. Ifektri yethu ihlanganisa indawo engamamitha-skwele angama-650, futhi isebenzisa amakhono angama-680 abasebenzi. Le ngqalasizinda eqinile isenza sikwazi ukukhiqiza amapayipi ensimbi esezingeni eliphakeme ahlangabezana namazinga we-ASTM A139, aqinisekise ukuthi imikhiqizo yethu ihlangabezana nezidingo eziqinile zamakhasimende ethu.

    I-ASTM A139ipayipi lensimbiOkujwayelekile kunomthelela omkhulu ekukhiqizweni kwe-S235 J0 Spiral Steel Pipe, Ukwenza ngcono ukukhiqiza okuguqukayo kanye nekhwalithi yomkhiqizo. Njengoba siqhubeka nokusungula nokwandisa amakhono ethu, sihlala sizibophezele ekuhlinzekeni izixazululo zensimbi eziphakeme ezihlangabezana nezidingo eziguqukayo zomkhakha.

    Umthandi

    Q1: Yini i-ASTM A139?

    I-ASTM A139 iyincazelo ejwayelekile echaza izidingo zepayipi lensimbi yokumelana nogesi. Lawa mapayipi asetshenziswa ngokujwayelekile kwizicelo ezicindezelwe okuphansi futhi aziwa ngamandla abo nokuqina kwawo. Izinga liqinisekisa ukuthi amapayipi ahlangabezana nezakhiwo eziqondene nemishini kanye nokwakheka kwamakhemikhali, ukuzenza zilungele ukusetshenziswa okuhlukahlukene kwezimboni.

    Q2: Yiziphi izinzuzo ze-S235 J0 Spiral Pipe?

    Enye yezinzuzo eziphambili ze-S235 J0 Spiral Spiral Pipe ukuguquguquka kwayo ngobubanzi kanye nokucaciswa kodonga. Lokhu kuvumelana nezimo kuvumela abakhiqizi ukuthi bakhiqize ibanga eliphakeme, ipayipi elibikwe ngodonga olungaphezulu olungamelana nezingcindezi ezinkulu nezingcindezi. Amandla okwenza lokhu okucaciswayo kwenza i-S235 J0 Pipe Pipe ibe ukukhetha okuhle kwamaphrojekthi adinga usayizi othize namandla.
