Iinkcukacha zeMveliso

Iithegi zeMveliso

Umbhobho womgca we-X60 SSAW, okwaziwa ngokuba ngumbhobho wombhobho ojikelezileyo we-spiral submerged arc welded, usebenzisa ii-hot-rolled steel coils njengezinto ezisetyenziswayo ukugoba umcu ube yimibhobho. Le nkqubo yokuvelisa yenza umbhobho ungabi namandla kwaye uhlale ixesha elide kuphela, kodwa umelana kakhulu nokugqwala kunye noxinzelelo. Ezi mpawu zibalulekile kwiumbhobho weoyile imigca, ezihlala ziphantsi kweemeko ezinzima zendalo kunye neemeko zoxinzelelo oluphezulu.

Uvavanyo lwe-Hydrostatic

Enye yezona nzuzo ziphambili zeX60Umbhobho womgca we-SSAWngamandla ayo aphezulu. Le mbhobho inomlinganiselo wokuvelisa ophantsi we-60,000 psi, nto leyo eyenza ukuba ilungele iimfuno zoxinzelelo oluphezulu lokuthuthwa kweoyile negesi. Inkqubo yokudibanisa i-spiral ikwaqinisekisa ukuba umbhobho unobukhulu obufanayo bodonga, nto leyo eyonyusa amandla awo kunye nokuthembeka kwawo.

Ukongeza kumandla, umbhobho womgca we-X60 SSAW waziwa ngokuguquguquka kwawo okugqwesileyo kunye nokuqina kwawo okunempembelelo. Oku kuthetha ukuba umbhobho uyakwazi ukumelana noxinzelelo kunye nobunzima bokuthuthwa kunye nokufakelwa ngaphandle kokuphazamisa ukuthembeka kwawo. Oku kubaluleke kakhulu kwimigca yepayipi yeoyile, edla ngokufuna ukunqumla umhlaba onzima kwaye yoyise imiqobo eyahlukeneyo ngexesha lokwakhiwa.

Ukongeza, umbhobho womgca we-X60 SSAW umelana kakhulu nokugqwala, nto leyo eyenza ukuba ube sisisombululo esihlala ixesha elide nesingabizi kakhulu kwimigca yepayipi yeoyile. Inkqubo yokudibanisa i-spiral idala umphezulu ogudileyo kunye nokugqwala okulinganayo, kunciphisa umngcipheko wokugqwala kwaye kwandise ubomi bombhobho. Oku kubalulekile kwioyile.umbhobhos, ezivezwa zizinto ezirhabaxa kunye nezinto ezingqongileyo ezinokonakalisa izixhobo ezikumgangatho ophantsi.

Ekwakhiweni kwemibhobho yeoyile, ukhuseleko kunye nokuthembeka kubaluleke kakhulu. Umbhobho womgca we-X60 SSAW uhambelana nazo zonke izinto apha, ubonelela ngesisombululo esomeleleyo, esihlala ixesha elide nesimelana nokugqwala esinokumelana nobunzima bokuthuthwa kweoyile negesi. Amandla ayo aphezulu, ukuguquguquka kwayo okugqwesileyo kunye nokuqina kwayo okunempembelelo kwenza ukuba ibe lukhetho oluthembekileyo kwiiprojekthi zemibhobho ezinzima kakhulu.

Ngamafutshane, umbhobho womgca we-X60 SSAW lolona khetho luphambili kwiipayipi zeoyile ngenxa yamandla ayo aphezulu, ukuqina kwayo kunye nokumelana nokugqwala. Inkqubo yayo yokudibanisa i-spiral ivelisa iipayipi ezinokumelana noxinzelelo oluphezulu, umhlaba onzima kunye neendawo ezingcolisayo, nto leyo eyenza ukuba zibe sisisombululo esithembekileyo nesingabizi kakhulu sokuthuthwa kweoyile negesi. Xa kusakhiwa iipayipi zeoyile, ukukhetha umbhobho wombhobho we-X60 spiral submerged arc welded sisigqibo sokuqinisekisa ukhuseleko kunye nokuthembeka komsebenzi wonke.
