    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Funda mayelana ne-A252 Grade 2 Steel Pipe:

    I-A252 IBANGA 2 Ipayipi Lensimbiiyipayipi lensimbi ye-carbon eklanyelwe ukusetshenziswa kumapayipi okucindezela kanye nezinhlelo zokusebenza zesakhiwo.Ikhiqizwa ngokuhambisana namazinga e-ASTM (American Society for Testing and Materials), iqinisekisa amazinga ekhwalithi ephezulu nokunemba kobukhulu.Ukuqokwa kwe-GRADE 2 kubonisa ukuthi ipayipi lensimbi lakhiwe kusetshenziswa i-arc welding engaphansi kwamanzi noma izindlela zokushisela ezingenamthungo.

    Ukubaluleka kokushisela kwe-arc engaphansi kwamanzi kabili:

    I-arc welding efakwe kabili emanzini, eyaziwa nangokuthi i-DSAW, iyinqubo yokushisela ekhetheke kakhulu esetshenziselwa ukuhlanganisa izingxenye zepayipi lensimbi elingu-A252 GRADE 2.I-DSAW inikeza izinzuzo ezimbalwa kunezinye izindlela zokushisela, okuhlanganisa ubuqotho be-weld obuhle kakhulu, isivinini esiphezulu sokushisela, ukuhlanekezela okuncane, nokulawula okuhle kakhulu kokufaka ukushisa.Iqinisekisa isibopho esiqinile phakathi kwamapayipi, okwenza angajwayele ukuvuza, ukugqwala kanye nokulimala kwesakhiwo.

    Kungani kusetshenziswa ipayipi lensimbi i-A252 Grade 2 kumaphrojekthi endle?

    1. AMANDLA ABANGAPHEZULU KANYE NOBUDLA: Ipayipi lensimbi le-A252 IBANGA LESI-2 linamandla aqine kakhulu, okulenza limelane nezingcindezi nezingcindezi zangaphandle.Ukuqina kwabo kuqinisekisa impilo yesevisi ende, kunciphisa isidingo sokushintshwa noma ukulungiswa njalo.

    2. Ukumelana Nokugqwala: Ipayipi lensimbi i-A252 GRADE 2 yakhelwe ukumelana nezimo ezinzima zangaphansi komhlaba, okuhlanganisa ukuchayeka endle, amakhemikhali kanye nomswakama, ngaphandle kokugqwala noma ukucekelwa phansi.Lesi sici sikhulisa kakhulu impilo yesevisi yamapayipi endle.

    3. Okungabizi kakhulu: Ipayipi lensimbi i-A252 yeBanga lesi-2 lihlinzeka ngesixazululo esingabizi kakhulu sokwakhiwa kwamapayipi endle.Izidingo zabo eziphansi zokunakekela kanye nokuhlala isikhathi eside kungasindisa omasipala kanye nosonkontileka bephrojekthi ukonga okukhulu ngokuhamba kwesikhathi.

    Izinqubo zokushisela amapayipi

    Ukusetshenziswa kwepayipi lensimbi i-A252 grade 2 kubunjiniyela bendle:

    Ipayipi lensimbi i-A252 GRADE 2 lisetshenziswa kabanzi kumaphrojekthi wengqalasizinda ehlukene yendle, okuhlanganisa:

    1. Uhlelo lukamasipala lokukhuculula indle: Amapayipi ensimbi angu-A252 eBanga lesi-2 asetshenziswa kakhulu ekwakhiweni kwamapayipi okukhuculula ingqalasizinda kamasipala ukuze kuthuthwe kahle amanzi angcolile esuka ezindaweni zokuhlala nezokuhwebelana awayise ezindaweni zokuwahlanza.

    2. Uhlelo Lokuthuthwa Kwendle: Izakhiwo zezimboni zidinga izinhlelo eziqinile zokukhuculula indle ukuze zibhekane nokuchithwa kwamanzi angcolile avela ezindaweni zokukhiqiza nezinye izinsiza.Ipayipi lensimbi le-A252 GRADE 2 linikeza amandla adingekayo kanye nokuqina kwalolu hlobo lokusetshenziswa kwepayipi lamanzi angcolile lezimboni.

    Ekuphetheni:

    Uma kufikaumzila wendleukwakhiwa, ipayipi yensimbi ye-A252 GRADE 2 ehlanganiswe nobuchwepheshe bokushisela i-DSAW inikeza amandla angenakuqhathaniswa, ukuqina nokusebenza okuphelele.Ukumelana nokugqwala kwayo okukhethekile, amandla aphakeme okuqina kanye nokusebenza kahle kwezindleko kuyenza ilungele izinhlobonhlobo zemiklamo yengqalasizinda yendle.Ngokwamukela lezi zinto ezithuthukisiwe nezindlela zokushisela, amadolobha angakhuphula kakhulu isikhathi sokuphila nokusebenza kahle kwezinhlelo zawo zendle, ehlise izindleko zokunakekela futhi aqinisekise indawo ehlanzekile, enempilo yawo wonke umuntu.
