Spiral Submerged Arc Welded Pipe In API 5L Line Umbhobho Applications

Inkcazelo emfutshane:

Kwicandelo lothutho lwe-oyile kunye negesi, ukusetyenziswa kwe-spiral submerged arc welded imibhobho kuya kuxhaphaka ngakumbi, ngakumbi kulwakhiwo lwe-API 5L yeenkqubo zemibhobho yomgca.I-SSAW (i-arc welded welded) umbhobho yaziwa ngamandla ayo aphezulu, ukuqina kunye nokuguquguquka, okwenza kube yinto efanelekileyo kwizicelo ezifunwayo ezifana neshishini leoli kunye negesi.

 umbhobho we-SSAWiveliswa kusetyenziswa inkqubo yokuwelda i-arc entywiliselweyo ebandakanya ukwenza icoil yentsimbi ibe yimo engqukuva kwaye emva koko isebenzisa i-arc ye-welding ukudibanisa imiphetho yekhoyili kunye.

Enye yeenzuzo eziphambili zokusebenzisa i-spiral submerged arc welded pipe kwi-API 5L izicelo zemibhobho yomgca kukukwazi kwabo ukumelana namanqanaba aphezulu oxinzelelo lwangaphakathi nangaphandle.Oku kubaluleke kakhulu kwishishini leoli kunye negesi, apho imibhobho ibonakaliswe kwiimeko ezinzima kunye nemithwalo enzima.Ukwakhiwa okuqinileyo kwemibhobho ye-SSAW kwenza kube yinto efanelekileyo kwimibhobho esebenza kuxinzelelo oluphezulu kunye namaqondo okushisa, ukubonelela ngesisombululo esinokwethenjelwa kunye nexesha elide lokuthuthwa kwezinto ezixabisekileyo.

Umbhobho-Piles-ASTM-A2522

Ukongeza, ukuguquguquka kombhobho we-arc odityanisiweyo we-spiral odibeneyo wenza kube lula ukuwufakela kunye nokugcina, nto leyo eyenza kube lula ukukhetha kwiiprojekthi zokwakhiwa kwemibhobho.Ukukwazi kwabo ukuguquguquka kunye nokuhambelana ne-contours yendalo yomhlaba kuphelisa imfuno yokwenziwa kwexabiso elibizayo kunye nokuchitha ixesha kunye nokunciphisa umngcipheko wokuvuza kunye nokusilela.Ukongeza, umphezulu wangaphakathi ogudileyo wemibhobho ye-SSAW unciphisa ukungqubana kunye nesiphithiphithi, okukhokelela ekuhambeni okusebenzayo kunye nokusetyenziswa okuphantsi kwamandla.

a.Indlela ye-deoxidation yonyulwa ngolu hlobo lulandelayo:

FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto ezibophelelayo zenitrogen ngokwezixa ezaneleyo zokubopha initrogen ekhoyo (umz. min. 0,020 % iyonke iAl okanye i-0,015 % enyibilikayo iAl).

b.Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukubunjwa kweekhemikhali kubonisa ubuncinane be-Al umxholo we-0,020 % kunye nomlinganiselo we-Al/N ubuncinane we-2: 1, okanye ukuba kukho ezinye izinto ezaneleyo ze-N-binding.Izinto ezibophelelayo ze-N ziya kubhalwa kuXwebhu loHlolo.

Isishwankathelo, ukusetyenziswa kwe-spiral submerged arc welded pipe kwi-API 5L izicelo zemibhobho yomgca inika uluhlu lweenzuzo ezenza kube yinto ekhangayo kwishishini leoli kunye negesi.Amandla abo, ukuqina kunye nokuguquguquka kwabo kubenza balungele ukusetyenziswa kwiindawo ezifunwayo, ngelixa ukulula kwabo ukufakela kunye neemfuno zokugcinwa okuphantsi zibonelela ngesisombululo esinexabiso eliphantsi kwiiprojekthi zokwakha imibhobho.Njengoko imfuno yothutho oluthembekileyo, olusebenzayo lwe-oyile, igesi yendalo kunye namanzi iqhubeka ikhula, ukubaluleka kwe-spiral submerged arc welded pipe kwi-API 5L yomgangatho wombhobho womgca awukwazi ukugqithiswa.Ngokusebenza kwayo okungqiniweyo kunye nokuguquguquka,umbhobho we-arc ojikelezayoimiselwe ukuqhubeka ukuba yinxalenye ebalulekileyo yeziseko ezingundoqo eziqhuba uqoqosho lwehlabathi.
