IiPilingi zeMbhobho yeNsimbi zeBanga lesi-2 ze-A252 zeZiseko kwiShishini lase-Offshore

Kwihlabathi elihlala litshintsha lophuhliso lweziseko zophuhliso, isidingo sezinto ezithembekileyo nezihlala ixesha elide sibaluleke kakhulu. Siyazingca ngokubonelela ngeenqwaba zethu zexabiso eliphezulu, ezenzelwe ukuhlangabezana nemigangatho engqongqo efunekayo kwimibhobho yegesi engaphantsi komhlaba. Iinqwaba zethu zenziwe ngokuchanekileyo, ukuqinisekisa ukuba inqwaba nganye ilinganiswa nganye ukuqinisekisa ukuthotyelwa kwemigaqo yeshishini.

Iipayipu zethu zenziwe ngentsimbi ye-A252 GRADE 2, into eyaziwa ngamandla ayo kunye nokuqina kwayo. Olu hlobo lwentsimbi lufanelekile ngokukodwa kwizicelo ezibandakanya ukufakelwa komhlaba apho ukuqina kwesakhiwo sezinto kubaluleke kakhulu. Umbhobho wentsimbi we-A252 GRADE 2 wenzelwe ukumelana neemeko ezinzima ezihlala zihlangana nazo kwiindawo ezingaphantsi komhlaba, nto leyo eyenza ukuba ibe lukhetho olufanelekileyo kwizicelo zepayipi yegesi.

Njengomgcini-mpahla othembekileyo wepayipi ye-SSAW (Spiral Submerged Arc Welded), siqinisekisa ukuba iimveliso zethu ziyahlangabezana nemigangatho ephezulu yomgangatho. Inqwaba nganye yepayipi yenziwe kusetyenziswa iindlela eziphambili zokuwelda ezonyusa amandla kunye nokuqina kwento. Ipayipi yethu ye-SSAW yaziwa ngeempawu zayo ezintle zoomatshini kwaye ifanelekile kwiintlobo ngeentlobo zezicelo, kubandakanya imibhobho yegesi yendalo engaphantsi komhlaba. Inkqubo yokuwelda ejikelezayo ayiboneleli nje kuphela ngesakhiwo esomeleleyo, kodwa ikwavumela ukuba kuveliswe ubude obude, okunciphisa isidingo samalungu kunye nokuphucula ukuthembeka ngokubanzi kofakelo.

Intsimbi mayingabi na-phosphorus engaphezulu kwe-0.050%.

Ubude ngabunye benqwaba yepayipi buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bayo abuyi kwahluka ngaphezu kwe-15% ngaphezulu okanye i-5% phantsi kobunzima bayo obuqikelelwayo, kubalwe kusetyenziswa ubude bayo kunye nobunzima bayo ngobude beyunithi nganye.
Ububanzi bangaphandle abuyi kwahluka ngaphezu kwe-±1% ukusuka kububanzi obuqhelekileyo bangaphandle
Ubukhulu bodonga nangaliphi na ixesha abuyi kuba ngaphezulu kwe-12.5% ​​phantsi kobukhulu bodonga obuchaziweyo.

Ubude obungacwangciswanga obunye: 16 ukuya kwi-25ft (4.88 ukuya kwi-7.62m)
Ubude obuphindwe kabini obungacwangciswanga: ngaphezulu kwe-25ft ukuya kwi-35ft (7.62 ukuya kwi-10.67m)
Ubude obufanayo: umahluko ovumelekileyo ±1in

Iipayipu mazifakelwe iziphelo ezingenanto, kwaye iziphelo ezisemaphethelweni mazisuswe.
Xa isiphelo sepayipi esichazwe njengesiphelo se-bevel, i-engile mayibe ngama-30 ukuya kuma-35 degrees

Ubude ngabunye benqwaba yepayipi buya kubonakaliswa ngokubonakalayo ngokuyibeka ngestencil, ukuyifaka isitampu, okanye ukuyiqengqa ukuze kuboniswe: igama okanye uphawu lomenzi, inombolo yobushushu, inkqubo yomenzi, uhlobo lomthungo ojikelezayo, ububanzi bangaphandle, ubukhulu bodonga obuqhelekileyo, ubude, kunye nobunzima ngobude beyunithi nganye, uphawu lwenkcazo kunye nomgangatho.

Uphawu oluphambili lweenqwaba zethu kukungqinelana kobunzima bazo. Inqwaba nganye ilinganiswa ngononophelo kwaye sinamathela kwiindlela ezingqongqo zokunyamezela ukuqinisekisa ukuba ubunzima abuguquki ngaphezu kwe-15% okanye i-5% yobunzima bethiyori. Oku kuchaneka kubalulekile kwiinjineli kunye nabakhi abaxhomekeke kwiinkcukacha ezichanekileyo zeeprojekthi zabo. Ngokugcina le migangatho yobunzima, sinceda ekuqinisekiseni ukuba inkqubo yokufakela ihamba kakuhle kwaye ukusebenza kwesakhiwo senqwaba kuhlangabezana nemigangatho elindelekileyo.

Ukuzinikela kwethu kumgangatho kudlulela ngaphaya kwenkqubo yokuvelisa. Siyaqonda ukuba impumelelo yayo nayiphi na iprojekthi equka imibhobho yegesi engaphantsi komhlaba ixhomekeke ekuthembekeni kwezinto ezisetyenzisiweyo. Ke ngoko, senza uhlolo olungqongqo lolawulo lomgangatho kuwo onke amanqanaba emveliso. Iqela lethu leengcali lizinikele ekuqinisekiseni ukuba yonke inqwaba iyahlangabezana neemfuno ezifunekayo kwaye ingasetyenziswa ngoko nangoko xa ihanjiswa.

Ukongeza kwiinqwaba ezikumgangatho ophezulu, sikwabonelela ngenkonzo egqwesileyo kubathengi kunye nenkxaso. Iqela lethu elinolwazi lihlala lifumaneka ukuphendula nayiphi na imibuzo onokuba nayo, linike isikhokelo sobugcisa, kwaye likuncede ukhethe iimveliso ezifanelekileyo kwiimfuno zakho ezithile. Siyazingca ngokwakha ubudlelwane bexesha elide nabathengi bethu, siqinisekisa ukuba abafumani nje kuphela imveliso yodidi oluphezulu, kodwa nenkxaso abayidingayo ukuze bagqibezele ngempumelelo iprojekthi yabo.

Ngamafutshane, iipayipi zethu zeprimiyamu ezenziwe ngentsimbi ye-A252 GRADE 2, ezifumaneka ngenkonzo yethu yomthengisi weepayipi ze-SSAW, zisisombululo esifanelekileyo kwiprojekthi yakho yepayipi yegesi engaphantsi komhlaba. Ngokuzibophelela kwethu kumgangatho, ukuchaneka, kunye nokwaneliseka kwabathengi, ungasithemba ukuba siza kukubonelela ngezixhobo ozidingayo ukuqinisekisa ukuba uphuhliso lwakho lweziseko luyimpumelelo kwaye lukhuselekile. Khetha iipayipi zethu zesisombululo esithembekileyo, esihlala ixesha elide, nesisebenzayo kwiimfuno zakho zokwakha phantsi komhlaba.
