    • Izinzuzo zamapayipi e-A252 Grade 3 asetshenziswa ekukhuculeni kwendle kanye nokwakhiwa kwepareroleum

    Incazelo emfushane:

    I-A252 I-Grade 3 Steel Pear, eyaziwa nangokuthiKuvunguza i-arc efakwe emgodini, ukukhetha okudumile kokwakhiwa kwendle kanye nowoyela wepayipi. Lawa mapayipi aklanyelwe ukubekezelela izimo ezedlulele futhi anikeze izinzuzo eziningi kulezi zinhlelo zokusebenza.

    Enye yezinzuzo ezisemqoka zeI-A252 Ibanga 3 Ipayipi lensimbi amandla awo ahlukile nokuqina. Lawa mapayipi enziwe ngensimbi esezingeni eliphakeme futhi amelana kakhulu nokugqwala, ukugqoka kanye nomthelela. Lokhu kubenza balungele ukusetshenziswa kumapayipi wendle lapho zingadalulwa khona ezintweni ezilimazayo kanye nemithwalo esindayo. Ngaphezu kwalokho, amandla abo nokuqina kwabenza bakwazi ukusetshenziswa ekwakhiweni kwamapayipi kawoyela, ngoba kufanele bamelane nezingcindezi eziphakeme kanye nokushintsha izimo zemvelo.

    Enye inzuzo ye-A252 Banga 3 Ipayipi lensimbi yinzuzo yayo ehlukahlukene. Lawa mapayipi ayatholakala ngosayizi ahlukahlukene nobukhulu, abenze balungele izinhlelo ezahlukahlukene. Ukuthi kwakha okuncaneumugqa wendlenoma umugqa omkhulu wepayipi wamafutha, i-A252 grade 3 ipayipi lensimbi angahle abekwe ngokwezifiso ukuze ahlangabezane nezidingo ezithile zephrojekthi. Ngokwengeziwe, la mapayipi angenziwaAmapayipi angenazibalo, kuphinde kwandise ukusetshenziswa kwabo emisebenzini yokwakha.

    Ngaphezu kwamandla ayo kanye nokuguquguquka okuhlukahlukene, i-A252 Ibanga 3 Ipayipi lensimbi kuyaziwa nangokuthi izindleko zalo. Lawa mapayipi akulula ukufaka futhi adinga ukulungiswa okuncane, ukunciphisa izindleko zephrojekthi jikelele. Ngokwengeziwe, impilo yabo yenkonzo ende nokumelana nokugqwala kuqinisekisa ukuthi bahlinzeka ngokubuyiselwa okuqinile ekutshalweni kwemali kwendle futhiipayipi kawoyela ulayiniamaphrojekthi wokwakha.

    Ipayipi le-SSAW

    Enye inzuzo ebalulekile ye-A252 I-Grade 3 yensimbi yensimbi ukuhambisana kwayo ngezindlela ezahlukahlukene zokwakha. Lawa mapayipi angafakwa kusetshenziswa izindlela zokumbilwa zendabuko noma amasu angenamikhawulo njengokushayela okuqondile okuqondile, ukuhluma kwepayipi noma ukuxhumeka kwepayipi. Lokhu kuguquguquka kuvumela ukufakwa okusebenzayo nokubizayo ngezindawo eziyinselele, kufaka phakathi izindawo zasemadolobheni, imigwaqo yamanzi kanye nezindawo ezibucayi zemvelo.

    Sekukonke, i-A252 I-Grade 3 Steel Pipe inikezela ngezinzuzo ezahlukahlukene zokukhucululwa kwendle kanye nokwakhiwa kwepayipi likaphethiloli. Amandla abo, ukuqina, ukuguquguquka kwezingxabano kanye nokusebenza kwezindleko kwenza bahlele ngalezi zinhlelo ezifunwayo. Noma ngabe isetshenziswa ekwakhekeni kwendle noma elolini lamafutha, la mapayipi ahlinzeka ngokusebenza okuthembekile nenani lesikhathi eside. Ngenxa yalokhu, bahlala ikhambi lokukhetha onjiniyela kanye nosonkontileka abafuna izixazululo eziqinile nezinokwethenjelwa kwamapayipi.
