Iinkcukacha zeMveliso

Iithegi zeMveliso

Umbhobho womgca we-X60 SSAW, okwaziwa ngokuba ngumbhobho we-arc odityanisiweyo we-arc, usebenzisa iikhoyili zentsimbi eziqengqelekayo njengemathiriyeli ekrwada ukugoba umcu ube yimibhobho.Le nkqubo yokuvelisa yenza umbhobho ungabi namandla kwaye uhlale uqinile, kodwa unqabile kakhulu kwi-corrosion kunye noxinzelelo.Ezi mpawu zibalulekileumbhobho weoyile imigca, ezihlala ziphantsi kweemeko ezinzima zokusingqongileyo kunye neemeko zoxinzelelo oluphezulu.

Uvavanyo lweHydrostatic

Enye yeenzuzo eziphambili zeX60Umbhobho womgca we-SSAWngamandla ayo aphezulu.Lo mbhobho unomlinganiselo omncinci wokuvelisa i-60,000 psi, okwenza kube yinto efanelekileyo kwiimfuno eziphezulu zoxinzelelo lweoli kunye nokuthutha igesi.Inkqubo ye-welding ye-spiral iqinisekisa ukuba umbhobho unobumba obufanayo bodonga, okwandisa ngakumbi amandla kunye nokuthembeka.

Ukongeza kumandla, umbhobho womgca we-X60 SSAW uyaziwa ngokugqwesa kwayo okugqwesileyo kunye nokuqina kwempembelelo.Oku kuthetha ukuba umbhobho uyakwazi ukumelana noxinzelelo kunye noxinzelelo lwezothutho kunye nokufakwa ngaphandle kokuphazamisa ingqibelelo yayo.Oku kubaluleke ngakumbi kwimigca yemibhobho yeoli, edla ngokufuna ukunqumla kumhlaba ocela umngeni kwaye yoyise imiqobo eyahlukeneyo ngexesha lokwakha.

Ukongeza, umbhobho womgca we-X60 SSAW awunyangeki kakhulu kwi-corrosion, okwenza ukuba ibe sisisombululo esihlala ixesha elide kunye neendleko ezifanelekileyo kwiintambo zemibhobho yeoli.Inkqubo ye-welding ye-spiral idala indawo epholileyo kunye ne-welds ehambelanayo, ukunciphisa umngcipheko wokubola kunye nokwandisa ubomi bombhobho.Oku kubalulekile kwioliumbhobhos, ezisesichengeni sezinto ezonakalisayo kunye nezinto ezisingqongileyo ezinokuthoba umgangatho wemathiriyeli ekumgangatho ophantsi.

Kulwakhiwo lwemibhobho yeoli, ukhuseleko nokuthembeka kubaluleke kakhulu.Umbhobho womgca we-X60 we-SSAW uphawula zonke iibhokisi ezilapha, ubonelela ngesisombululo esomeleleyo, esomeleleyo kunye nesokudusa esinokumelana nobunzima bokuthuthwa kweoyile negesi.Amandla ayo aphezulu, i-ductility egqwesileyo kunye nokuqina kwempembelelo kuyenza ibe lukhetho oluthembekileyo kwezona projekthi zinzima kakhulu.

Isishwankathelo, umbhobho womgca we-X60 SSAW lolona khetho lokuqala kwimibhobho yeoli ngenxa yamandla ayo aphezulu, ukuqina kunye nokumelana nokugqwala.Inkqubo yayo ye-spiral welding ivelisa imibhobho ekwaziyo ukumelana noxinzelelo oluphezulu, umngeni we-terrain kunye nemekobume enomhlwa, iyenza ibe sisisombululo esithembekileyo nesingabizi kakhulu sothutho lwe-oyile negesi.Xa kusakhiwa imibhobho yeoli, ukukhetha i-X60 spiral submerged arc welded pipeline pipe sisigqibo sokuqinisekisa ukhuseleko nokuthembeka komsebenzi wonke.
