Ukuphucula iziseko zogutyulo kusetyenziswa iSpiral Submerged Arc Pipes (SSAW)

Inkcazelo emfutshane:

Le nxalenye yalo Mgangatho waseYurophu ichaza iimeko zokuhanjiswa kobugcisa kulwakhiwo oludityanisiweyo olubandayo, amacandelo angenanto eesetyhula, isikwere okanye iifomu ezixande kwaye isebenza kumacandelo akhiweyo anomngxuma abandayo ngaphandle konyango lobushushu obulandelayo.

I-Cangzhou Spiral Steel Pipes Group Co., Ltd ibonelela ngecandelo elimngxuma leemibhobho zentsimbi ezijikelezayo kwisakhiwo.

Isishwankathelo sombhobho odityanisiweyo we-arc odityanisiweyo:

Umbhobho we-arc ontywiliselweyo, eyaziwa ngokuba yi-spiral submerged arc welded pipe, yenziwa ngokuqengqeleka intsimbi eshushu esongwayo ibe yimilo engqukuva kwaye iwudibanise ecaleni kwe-weld seam kusetyenziswa indlela ye-arc yokuwelda entywiliselweyo.Le mibhobho inika umgangatho ophezulu wokuqina, ukomelela kunye nokumelana nomhlwa, okwenza ukuba ibe yinto efanelekileyo kwiiprojekthi zeziseko ezingundoqo ezifana nemijelo ehambisa amanzi amdaka.

Izinto eziluncedo zombhobho we-SSAW kwizicelo zogutyulo:

1. Ukuqina: Imibhobho edityanisiweyo ye-arc edityanisiweyo ye-spiral yenziwe ngentsimbi ekumgangatho ophezulu kwaye inokuqina okugqwesileyo.Banamandla okumelana nemithwalo enzima kunye neemeko ezigqithisileyo eziphantsi komhlaba, ziqinisekisa ubomi obude benkonzo kwimibhobho yogutyulo.

2. Ukumelana nokuMhlwa: Inkqubo yokufaka igalvanizing yediphu eshushu yongeza umaleko owongezelelweyo wokhuseleko kumbhobho odityanisiweyo we-arc odityanisiweyo, nto leyo eyenza ukuba ikwazi ukumelana nomhlwa.Le propati ibaluleke kakhulu kwiinkqubo zogutyulo kuba zihlala zidibana neekhemikhali ezinobundlobongela kunye nemekobume yebhayoloji.

3. Uyilo olungavuziyo: Umbhobho odityanisiweyo we-arc odityanisiweyo wenziwa kusetyenziswa inkqubo yokuwelda eqhubekayo ukuqinisekisa ubume obungavuzi.Olu phawu luthintela nayiphi na into enokwenzeka yokungena okanye ukuvuza, ngaloo ndlela kuncitshiswa ukungcoliseka komhlaba kunye nesidingo sokulungiswa okuxabisa kakhulu.

4. Ukuguquguquka kunye nokuguquguquka: Umbhobho odityanisiweyo we-arc odibeneyo we-Spiral unokwenziwa ukuze ulungele iintlobo ezahlukeneyo zeedayamitha, ubude kunye nemithambeka, evumela ukuguquguquka okukhulu kuyilo lwenkqubo yogutyulo.Banokuziqhelanisa ngokulula notshintsho lwendawo kunye necala ngakulo, beqinisekisa ukuhamba kakuhle kwamanzi amdaka nakuthungelwano oluntsonkothileyo logutyulo.

5. Iindleko-zokusebenza: Xa kuthelekiswa nezinto zemibhobho yelindle yemveli efana nekhonkrithi okanye udongwe, imibhobho edityanisiweyo ye-arc edityanisiweyo inokubonelela ngeendleko ezibalulekileyo zogcino kufakelo nokugcinwa.Ubume bazo obukhaphukhaphu bunciphisa iindleko zokuthumela kwaye kulula ukuzifaka, ukunciphisa iimfuno zabasebenzi.Ukongezelela, ubomi bayo benkonzo ende kunye neemfuneko ezincinci zokulondoloza zinegalelo ekusebenzeni kweendleko zexesha elide.

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.

Ukusetyenziswa kwemibhobho ye-SSAW kwiinkqubo zogutyulo:

1. Uthungelwano lweMijelo kaMasipala: Imibhobho ye-SSAW idla ngokusetyenziswa ekwakhiweni kwemibhobho yogutyulo oluphambili olunceda iindawo zokuhlala, zorhwebo kunye nezoshishino.Amandla abo kunye nokumelana nomhlwa kubenza babe lolona khetho lubalaseleyo lokuthutha amanzi amdaka kumgama omde.

2. Ukuhanjiswa kwamanzi esiphango:imibhobho ye-SSAWinokulawula ngokukuko ukuhla kwamanzi esiphango kwaye ithintele izikhukhula kwimimandla yasezidolophini.Ukuqina kwabo kuvumela ukuhanjiswa ngokufanelekileyo komthamo omkhulu wamanzi kuxinzelelo lwamanzi aphezulu.

3. Iziko lokucoca ugutyulo: Imibhobho edityanisiweyo ye-arc edityanisiweyo ye-Spiral ingasetyenziswa kulwakhiwo lweendawo ezahlukeneyo zokucoca ugutyulo, kubandakanywa imibhobho ekrwada yogutyulo, iitanki zokungenisa umoya kunye neenkqubo zokucocwa kodaka.Ukuxhathisa kwabo kwimichiza eyonakalisayo kunye nokukwazi ukumelana noxinzelelo olwahlukeneyo kubenza babaluleke kakhulu kwindawo enzima ngolo hlobo.

Ukuququmbela:

Ukukhetha imathiriyeli yombhobho echanekileyo ibalulekile kulwakhiwo oluyimpumelelo nololongo lwenkqubo yakho yogutyulo.Umbhobho we-Spiral submerged arc (SSAW) ubonakalise ukuba sisisombululo esingabizi kakhulu, esihlala sihleli kwaye sisebenza ngeendlela ezininzi.Ngokumelana kwayo nokugqwesa okugqwesileyo, uyilo lobungqina bokuvuza, kunye nokuqhelana nemimandla eyahlukeneyo, imibhobho ye-SSAW inokuhambisa amanzi amdaka ngokufanelekileyo, inegalelo kuphuhliso oluzinzileyo lwezixeko.Ukusetyenziswa kwemibhobho edityanisiweyo ye-arc edityanisiweyo kwiiprojekthi zogutyulo kungavula indlela yothungelwano oluphuculweyo lwemijelo ehambisa amanzi amdaka ukuhlangabezana neemfuno ezikhulayo zophuhliso lwedolophu.
