Izinsika Zepayipi Lensimbi Lebanga 2 le-A252 Zezisekelo Embonini Yasogwini

Ezweni elihlala lishintsha lokuthuthukiswa kwengqalasizinda, isidingo sezinto ezithembekile nezihlala isikhathi eside sibaluleke kakhulu. Siyaziqhenya ngokunikeza ama-pile ethu aphezulu, aklanyelwe ukuhlangabezana nezindinganiso eziqinile ezidingekayo zamapayipi egesi angaphansi komhlaba. Ama-pile ethu akhiqizwa ngokunemba, okuqinisekisa ukuthi i-pile ngayinye ilinganiswa ngayinye ukuqinisekisa ukuhambisana nemininingwane yemboni.

Izinqwaba zethu zamapayipi zenziwe ngensimbi engu-A252 GRADE 2, into eyaziwa ngamandla ayo nokuqina kwayo. Le nsimbi yezinga ifaneleka kakhulu ekusetshenzisweni okubandakanya ukufakwa ngaphansi komhlaba lapho ubuqotho besakhiwo sento bubaluleke kakhulu. Ipayipi lensimbi engu-A252 GRADE 2 lenzelwe ukumelana nezimo ezinzima ezivame ukuhlangatshezwa ezindaweni ezingaphansi komhlaba, okwenza kube ukukhetha okuhle kokusetshenziswa kwamapayipi egesi.

Njengomthengisi othembekile wepayipi le-SSAW (Spiral Submerged Arc Welded), siqinisekisa ukuthi imikhiqizo yethu ihlangabezana nezindinganiso zekhwalithi ephezulu. Inqwaba ngayinye yepayipi yenziwa kusetshenziswa amasu okushisela athuthukisiwe akhulisa amandla nokuqina kwezinto. Ipayipi lethu le-SSAW laziwa ngezakhiwo zalo ezinhle kakhulu zemishini futhi lifanelekela izinhlelo ezahlukene, kufaka phakathi amapayipi egesi yemvelo angaphansi komhlaba. Inqubo yokushisela ejikelezayo ayinikezi nje isakhiwo esiqinile, kodwa futhi ivumela ukuthi kukhiqizwe ubude obude, kunciphisa isidingo samalunga futhi kuthuthukiswe ubuqotho bokufakwa.

Insimbi akumele ibe ne-phosphorus engaphezu kuka-0.050%.

Ubude ngabunye benqwaba yamapayipi kufanele bulinganiswe ngokwehlukana futhi isisindo sawo akufanele sihluke ngaphezu kuka-15% noma u-5% ngaphansi kwesisindo sawo esicatshangelwayo, kubalwe kusetshenziswa ubude bawo kanye nesisindo sawo ngobude beyunithi ngayinye.
Ububanzi bangaphandle akufanele buhluke ngaphezu kuka-±1% kusuka kububanzi obujwayelekile bangaphandle obubekiwe
Ubukhulu bodonga nganoma yisiphi isikhathi akufanele bube ngaphezu kuka-12.5% ​​ngaphansi kobukhulu bodonga obubekiwe

Ubude obungahleliwe obubodwa: 16 kuya ku-25ft (4.88 kuya ku-7.62m)
Ubude obuphindwe kabili obungahleliwe: ngaphezu kwamafidi angu-25 kuya ku-35 (7.62 kuya ku-10.67m)
Ubude obufanayo: ukuhlukahluka okuvunyelwe ±1in

Izinqwaba zamapayipi kumele zifakwe iziphetho ezingenalutho, bese kuthi izimbobo ezisemaphethelweni zisuswe.
Uma ukuphela kwepayipi okuchazwe ukuthi kube yiziphetho ze-bevel, i-engeli kufanele ibe ngama-degree angu-30 kuya kwangu-35.

Ubude ngabunye benqwaba yamapayipi kufanele buphawulwe ngokugqama ngokufaka isitembu, ukugxisha, noma ukugoqa ukuze kuboniswe: igama noma uhlobo lomkhiqizi, inombolo yokushisa, inqubo yomkhiqizi, uhlobo lomthungo ogobile, ububanzi bangaphandle, ukujiya kodonga okujwayelekile, ubude, nesisindo ngobude beyunithi, ukubizwa kwencazelo kanye nebanga.

Isici esibalulekile sama-pile ethu ukuqina kwesisindo sawo. I-pile ngayinye ikalwa ngokucophelela futhi sinamathela ezimisweni eziqinile zokuqinisekisa ukuthi isisindo asishintshi ngaphezu kuka-15% noma u-5% wesisindo esisekelwe kumbono. Lokhu kunemba kubalulekile konjiniyela kanye nabakhi abathembele ezimisweni ezinembile zamaphrojekthi abo. Ngokugcina lezi zindinganiso zesisindo, sisiza ekuqinisekiseni ukuthi inqubo yokufaka ihamba kahle nokuthi ukusebenza kwesakhiwo sama-pile kuhlangabezana nezindinganiso ezilindelekile.

Ukuzibophezela kwethu ekhwalithini kudlulela ngale kwenqubo yokukhiqiza. Siyaqonda ukuthi impumelelo yanoma yimuphi umsebenzi ohilela amapayipi egesi angaphansi komhlaba incike ekuthembekeni kwezinto ezisetshenziswayo. Ngakho-ke, senza ukuhlolwa okuqinile kokulawula ikhwalithi kuzo zonke izigaba zokukhiqiza. Ithimba lethu lochwepheshe lizinikele ekuqinisekiseni ukuthi yonke inqwaba ihlangabezana nezimfuneko ezidingekayo futhi ingasetshenziswa ngokushesha lapho ithunyelwa.

Ngaphezu kwama-piles asezingeni eliphezulu, siphinde sinikeze isevisi yamakhasimende enhle kakhulu kanye nokusekelwa. Ithimba lethu elinolwazi lihlala litholakala ukuphendula noma yimiphi imibuzo ongase ube nayo, linikeze isiqondiso sobuchwepheshe, futhi likusize ukhethe imikhiqizo efanele izidingo zakho ezithile. Siyaziqhenya ngokwakha ubudlelwano besikhathi eside namakhasimende ethu, siqinisekisa ukuthi awatholi nje kuphela umkhiqizo osezingeni eliphezulu, kodwa futhi nokusekelwa akudingayo ukuze aqedele ngempumelelo iphrojekthi yawo.

Ngamafuphi, izinqwaba zethu zamapayipi zekhwalithi ephezulu ezenziwe ngensimbi ye-A252 GRADE 2, ezitholakala ngensizakalo yethu yomthengisi wamapayipi e-SSAW, ziyisixazululo esiphelele sephrojekthi yakho yamapayipi egesi angaphansi komhlaba. Ngokuzibophezela kwethu ekhwalithini, ekuqondeni, nasekunelisekeni kwamakhasimende, ungasithemba ukuthi sizokunikeza izinto ozidingayo ukuqinisekisa ukuthi ukuthuthukiswa kwengqalasizinda yakho kuyaphumelela futhi kuphephile. Khetha izinqwaba zethu zamapayipi ukuze uthole ikhambi elithembekile, elihlala isikhathi eside, nelisebenzayo ezidingweni zakho zokwakha ngaphansi komhlaba.
