Yazisa:

Kwinkalo yobunjineli bezakhiwo, ukubaluleka kokusetyenziswa kwezinto ezisemgangathweni kunye neendlela zokwakha azikwazi ukugqithiswa.Phakathi kwamacandelo ahlukeneyo asetyenziswa kwiiprojekthi zokwakha, imibhobho inendima ebalulekileyo.Siza kukhanyisa ngokubaluleka kwemibhobho edityanisiweyo kabini kwaye sihlolisise iimpawu zayo, iinzuzo kunye nendlela enokunceda ngayo ukunyusa imfezeko yesakhiwo.

Funda malunga nemibhobho edityaniswe kabini:

Umbhobho odityanisiweyo kabini, owaziwa ngokuba ngumbhobho odityanisiweyo we-arc (Imibhobho ye-DSAW), yenziwa kusetyenziswa inkqubo ye-arc welding ephantsi kwamanzi.Itekhnoloji ibandakanya ukuxuba iipleyiti zentsimbi ezimbini ezihlukeneyo ngobude, zibonelela ngonxibelelwano oluqinileyo noluqhubekayo.Le mibhobho isetyenziswa ikakhulu kwizicelo zoxinzelelo oluphezulu, amanzi aphantsi komhlaba kunye nemibhobho yerhasi yendalo, ukuhlola i-oyile, kunye namaqonga angaphesheya konxweme.

Nyusa isidima solwakhiwo:

Isizathu esiphambili sokusebenzisaumbhobho odityanisiweyo kabinikukukwazi kwabo ukomeleza imfezeko yesakhiwo.Ngee-welds ezingenamthungo kunye nezomeleleyo, le mibhobho inikezela ukuxhathisa uxinzelelo kunye nokuqina.I-double weld iqinisekisa ukuba umbhobho unokumelana namanqanaba aphezulu oxinzelelo, okwenza kube yinto efanelekileyo kwizicelo ezibalulekileyo apho i-weld enye inokuphazamisa ukhuseleko lwesakhiwo.Le nkqubo ye-welding ephindwe kabini iphelisa ukuvuza okanye ukuqhekeka, iqinisekisa ukuthembeka kwexesha elide lenkqubo yakho yombhobho.

Amandla aphezulu kumlinganiselo wobunzima:

Umbhobho odityanisiweyo ophindwe kabini unika amandla abalaseleyo kumlinganiselo wobunzima.Ngenxa yenkqubo ye-welding, le mibhobho iyancipha ubukhulu bodonga kwaye ilula ngelixa igcina ukuqina kwesakhiwo.Le nzuzo yomlinganiselo wamandla-kuya kubunzima bunciphisa umthwalo opheleleyo kwisakhiwo esixhasayo, okwenza kube isisombululo esineendleko eziphezulu kwiiprojekthi ezinkulu ezifana neebhulorho, iinqaba kunye nezakhiwo eziphakamileyo.

Ukuchasa umhlwa:

Enye inzuzo ebalulekileyo yombhobho odityanisiweyo ophindwe kabini kukuxhathisa ukubola.Isitywina esiqinileyo esitywiniweyo senza umqobo oqinileyo ngokuchasene nezinto zangaphandle, kubandakanywa ukufuma, iikhemikhali kunye neempawu zomhlaba.Oku kuthintela umphezulu wangaphakathi wombhobho ekudibaneni ngokuthe ngqo kunye nee-arhente ezitshabalalisayo, ukuqinisekisa ubomi obude benkonzo xa kuthelekiswa nemibhobho eqhelekileyo.Iipropathi ezichasene ne-corrosion yale mibhobho inenzuzo ngokukodwa kwishishini leoli kunye negesi, apho imibhobho ihlala idibana neemeko ezinzima.

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.

Iimpawu ezisebenzayo zendlela:

I-smooth, engaphazamisekiyo yangaphakathi yombhobho we-welded kabili ivumela iimpawu ezihamba kakuhle.Ngokungafaniyo nezinye iintlobo zemibhobho eneeprotrusions zangaphakathi okanye izithintelo, le mibhobho iqinisekisa ngokuqhubekayo kunye nokuhamba kwamanzi okanye igesi, ngaloo ndlela inciphisa ilahleko ye-friction.Iimpawu ezihamba kakuhle zombhobho odityanisiweyo ophindwe kabini zinceda ukwandisa ukusebenza kweenkqubo ezahlukeneyo zoshishino, kubandakanywa izityalo ze-petrochemical, ii-refineries kunye nezixhobo zokunyanga amanzi.

Ukuququmbela:

Ukuqukumbela, umbhobho odityaniswe kabini licandelo elibalulekileyo eliphakamisa ngokubonakalayo imfezeko yolwakhiwo lweeprojekthi ezahlukeneyo zokwakha.Iimpawu zabo ezikhethekileyo, ezibandakanya i-welds ezingenamthungo, umlinganiselo ophezulu wobunzima bobunzima, ukuxhatshazwa kwe-corrosion kunye nokuhamba okusebenzayo, kubenza kube yinto yokuqala yokukhetha izicelo ezifuna ukuthembeka, ukuqina kunye nokusebenza kakuhle kweendleko.Ngokusebenzisa umbhobho odityanisiweyo ophindwe kabini, iinjineli kunye neekontraka zinokuqinisekisa ukusebenza okuhlala ixesha elide kunye nokukhuselekileyo kweziseko ezingundoqo ezibalulekileyo, okwenza kube yimpahla ebalulekileyo kwiindawo zokwakha nezobunjineli.

Umbhobho we-SSAW

Isishwankathelo, i-S235 J0 ipayipi yensimbi ejikelezayo inika umgangatho ongenakulinganiswa kunye nokuqina kwakhoubukhulu obukhulu welded pipeiimfuno.Ngeenkqubo zabo zokuvelisa eziphucukileyo, umgangatho ophezulu we-welding kunye nokuhlolwa okucokisekileyo komgangatho, iimveliso zethu ziqinisekisiwe ukuba ziya kudlula ulindelo lwakho.Trust Cangzhou Spiral Steel Pipe Group Co., Ltd.'s ubungcali kunye namava ukuhlangabezana nazo zonke iimfuno zakho umbhobho yentsimbi.
