    Ipayipi eliphakeme kakhulu lekhwalithi enkulu yepayipi

    Ikhwalithi ephezulu kakhulu yobubanzi bepayipi eliveziwe
    • Ipayipi eliphakeme kakhulu lekhwalithi enkulu yepayipi

    Incazelo emfushane:

    Idizayinelwe ukumelana nobunzima bokwakhiwa okusindayo, amapayipi ethu aphezulu, amapayipi amakhulu ahlukahlukene anikezela amandla nokuqina okudingekayo ukuze uthole ukwesekwa kwesisekelo. Ubuchwepheshe be-Welding Spiral obusetshenzisiwe kwinqubo yethu yokukhiqiza buqinisekisa ukwakheka okungenamthungo ne-STRAMENT, ukunciphisa ingozi yokwehluleka nokukhulisa impilo yenkonzo.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Sethula amapayipi amakhulu aphezulu abuyisi, okuyikhambi elifanelekile lokuhlangabezana nezidingo eziguqukayo zokushintsha kwezokwakha nokuthuthukiswa kwengqalasizinda. Njengoba imboni ifakazela ukwanda okukhulu ngosayizi wamapayipi angenayo, isidingo sezinto eziqinile nezinokwethenjelwa akukaze kube okuphuthumayo ngokwengeziwe. Izingcingo zethu ezinkulu ze-Weld Expored Insimbi yamapayipi ensimbi zenzelwe ukufeza lezi zinselelo, ziqinisekisa ukusebenza okuphezulu nokuqina kwezicelo ezahlukahlukene.

    Yakhelwe ukumelana nobunzima bokwakhiwa okunzima, ikhwalithi yethu ephezulu,Amapayipi amakhulu abuyimithaNikeza amandla nokuqina okudingekayo ukuze uthole ukwesekwa kwesisekelo. Ubuchwepheshe be-Welding Spiral obusetshenzisiwe kwinqubo yethu yokukhiqiza buqinisekisa ukwakheka okungenamthungo ne-STRAMENT, ukunciphisa ingozi yokwehluleka nokukhulisa impilo yenkonzo. Ukuthi ubamba iqhaza kumaphrojekthi wezentengiselwano, ehlala engqalasizinda, amapayipi ethu okuphola ayisinqumo esifanele sokuhlangabezana nezidingo zakho.

    Inzuzo yomkhiqizo

    Enye yezinzuzo eziphambili zokusebenzisa amapayipi amakhulu abuyisiwe amandla okumelana nemithwalo esindayo. Lawa mapayipi aklanyelwe ukubekezelela ingcindezi enkulu, abenze balungele izinhlelo ezijulile zesisekelo kumaphrojekthi amakhulu wokwakha. Ububanzi babo obukhulu bukhulisa nokuchithwa kwenhlabathi, ngaleyo ndlela bathuthukise ukuqina kanye nokunciphisa izindaba zokuhlala. Ngaphezu kwalokho, inqubo ye-welding eluhlaza esetshenziselwa ukwenziwa kwalawa mapayipi aqinisekisa ibhondi eqinile futhi ehlala isikhathi eside, incishise ubungozi bokuhluleka kwesakhiwo.

    Ukushiyeka komkhiqizo

    Izindleko zokukhiqiza ipayipi eliphakeme eliphakeme kakhulu le-main-diineter lingaba ngaphezulu kwezinketho zendabuko, ezingathinta izabelomali zephrojekthi.

    Ngaphezu kwalokho, inqubo yokufaka ingaba yinkimbinkimbi futhi idle isikhathi, idinga imishini ekhethekile kanye nabasebenzi abanamakhono. Uma kungalawulwa kahle, lokhu kungadala ukubambezeleka kokusebenzisa umugqa wesikhathi.

    Isicelo

    Emhlabeni okhulayo okhulayo wokuthuthuka kokwakha nokuthuthuka kwengqalasizinda, isidingo sezinto eziqinile sibaluleke kakhulu. Into eyodwa etholile ukunakwa okuningi ikhwalithi ephezulu, ipayipi elikhulu elibuyisiwe. Njengoba amaphrojekthi wokwakha anda ngosayizi nobunzima, isidingo sezinhlangothi ezinkulu, izixazululo ezihlala isikhathi eside ziba yindawo.

    Ngokuthuthuka okusheshayo kokufuduka kwamadolobha kanye namaphrojekthi wengqalasizinda, ububanzi bamapayipi okuphola buyaqhubeka ukukhulisa ukufeza izidingo zobunjiniyela banamuhla. Ikhwalithi ephezuluIpayipi lensimbi enkuluAma-Piles abalulekile ukuhlinzeka ngosizo oludingekayo nokuqina kwezakhiwo ezahlukahlukene njengamabhuloho, izakhiwo kanye nezindawo zasolwandle. Lawa mapayipi aklanyelwe ukubekezelela imithwalo emikhulu kanye nezimo ezinokhahlo kwezemvelo, eqinisekisa isikhathi eside kanye nokuphepha kwamaphrojekthi abasekayo.

    Njengoba imboni yezokwakha iyaqhubeka nokuvela, ukubaluleka kwepayipi elikhulu eliphakeme kakhulu lokuphamba kwamandla akwazi ukweqiwa. Ukuzibophezela kwethu kwikhwalithi kanye nokwenza izinto ezintsha kuqinisekisa ukuthi sihlala singumlingani othembekile embonini yezokwakha, ukuhlinzeka ngezinto ezibalulekile ezidingekayo kwingqalasizinda yesikhathi esizayo. Noma ngabe ubamba iqhaza kwiphrojekthi enkulu noma kwiphrojekthi yokwakha encane, amapayipi ethu amakhulu okuphamba akunikeza amandla nokuthembela okudingayo.

    Q1: Uyini umbhobho omkhulu we-pieter?

    Amapayipi amakhulu okuphoqa ama-cishi asetshenziselwa izinhlaka ze-cylindrical ezisetshenziselwa ukusekela imithwalo esindayo emisebenzini yokwakha. Ububanzi babo obukhulayo buhlinzeka umthamo omkhulu womthwalo futhi ulungele izisekelo ezijulile ezimweni eziyinselele zenhlabathi.

    Q2: Kungani ukhetha ipayipi le-welded welded lensimbi?

    Kuvunguza amapayipi ensimbi we-welded adaziwa ngamandla abo aphezulu nokuqina. Inqubo ye-welding eluhlaza iqinisekisa umthungo oqhubekayo, othuthukisa ubuqotho bepayipi. Le ndlela ibuye ivumele ukukhiqizwa kwamapayipi ensimbi akhudlwana ukuze ahlangabezane nezidingo ezikhulayo zokwakhiwa kwanamuhla.

    Q3: Aphi la mapayipi enziwe?

    Amapayipi ethu aphezulu we-macial pipes akhiqizwa eCangzhou, eSifundazweni saseHebei. Ifektri yethu yasungulwa ngonyaka we-1993 futhi ihlanganisa indawo engamamitha-skwele angama-350,000 anezimpahla eziphelele ze-RMB 680 million. Sine-680 abasebenzi abazinikezele abanikezelwe ekukhiqizeni izindawo eziphakeme zokusebenzisa izixazululo ezihlangabezana nezidingo eziqinile zemboni yezokwakha.
