I-Weldied Pipe vs yentsimbi yentsimbi

Bobabini ukuchasana nombane kwi-welded Ixesha elingaphezulu, iindlela ezisetyenziselwa ukuvelisa nganye ihambe kakuhle. Ke yeyiphi engcono?

Umbhobho we-weldie uqala nje njenge-ribbon ende, edityanisiweyo yentsimbi ebizwa ngokuba yiSkelp. I-Skelp inqunyulwe kude kube lixesha elifunekayo, elikhokelela kwiphepha elinongxande. Ububanzi belo phepha mfutshane zephepha lomfutshane ziya kuba yindawo yomphunga engaphandle, ixabiso elinokusetyenziswa ukubala ububanzi bayo bangaphandle.
Amaphepha oxande atyalwa ngamatshini oqengqelekayo ojikelezayo amacala amade phezulu kwelinye, enze isilinda. Kwinkqubo ye-ERW, umbane oPhakamileyo oPhezulu udluliselwe phakathi kwemiphetho, ebangela ukuba banyibilike kunye ne-fuse kunye.
Inzuzo yombhobho we-Erw kukuba akukho zinyithi ze-fusion zisetyenziswa kwaye umthungo we-weld awunakubonwa okanye uziva. Oko kuchasene nokufumana i-arc ye-arc engaphantsi kwe-ARC (i-DSAW), eshiya ngasemva kwe-weld yedlelo ekufuneka isuswe kuxhomekeka kwisicelo.
Iindlela zokwenza i-welding ze-welding ziphuculwe kwiminyaka edlulileyo. Mhlawumbi eyona nkqubela ibaluleke kakhulu iye yatshintsha kwi-currey ephezulu yombane. Ngaphambi kwe-1970s, i-frequency ephantsi yasetyenziswa okwangoku. I-WEDD SEAMS EVULELWE UKUVULA NGOKUGQIBELA NGOKUGQIBELA KWAKHONA KUKHONA KUNYE NOKUGQIBELA.
Uninzi lweentlobo zeplanga ze-welding zifuna unyango lobushushu emva kwemveliso.

I-2. Ukuvelisa umbhobho ongenamthungo
I-piiling engenamthungo iqala njengendawo eqinileyo ye-cylindrical yentsimbi ebizwa ngokuba yiBillet. Ngelixa ushushu, ii-billets zihlatywe kwiziko nge-mandrel. Inyathelo elilandelayo liqengqeleka kwaye liyolula i-billlet billet. I-billlet iqengqelwe ngokuchanekileyo kwaye iyolule de ihlangabezane nobude, ububanzi kunye nobubanzi bodonga njengoko kuchaziwe ngumyalelo wabathengi.
Iindidi zemibhobho ye-pile ezingenamthungo zikhubazekile, ngoko ke unyango olushushu emva kwemveliso ayifuneki. Abanye bafuna unyango lobushushu. Nxibelelana nenkcazo yohlobo lomphunga olungenamthungo oluthathela ukufunda ukuba luya kufuna unyango lobushushu.

I-3. Imbali yembali kwaye isebenzise amatyala okufumana i-weldid vs.
I-erw kunye ne-piiding yentsimbi yentsimbi ikhona njengezinye iindlela zanamhlanje kakhulu ngenxa yeendlela zembali.
Ngokubanzi, umbhobho we-welding wathathwa njengobuthathaka ngokwentlukwanga kuba iquka umthungo we-wel. Umbhobho ongenamthungo uswele lo mthetho uthawulweyo kwaye wathathwa njengento ekhuselekileyo. Ngelixa kuyinyani ukuba umbhobho we-welding ubandakanya umthungo owenza ukuba ityhelwe ngokwenyani, ubuchule bokuqinisekisa imigangatho kunye nerejimeni yokuqinisekisa umgangatho kunye nerejimeni ye-pipe ye-Weldie iya kudlula xa i-derances idlule kuyo xa i-deranced idlule khona xa i-deranced idlule kuyo xa i-deranced idlule kuyo xa i-derances yayo idlulile. Ngelixa intsingiselo ebonakalayo icacile, ukugxekwa kwe-pipple ye-waiding kukuba inkqubo yokuqengqeleka kunye neyolula ivelisa ubukhulu becala obungahambelaniyo xa kuthelekiswa nobungqingqwa obuqiqiweyo beentsimbi ezimiselwe i-welding.
Imigangatho yeshishini elawula ukuqulunqwa kunye nokuchazwa kwe-orw kunye nomngxunya wentsimbi engenamthungo ebonisa ezo tions. Umzekelo, ukumiswa okungenamthungo kuyafuneka kuxinzelelo oluphezulu, usetyenziso oluphezulu kwi-oyile kunye negesi, ukuvelisa amandla kunye namashishini amayeza. I-piiling ye-welding (ebiza kakhulu ukuba ivelise kwaye ifumaneka ngokubanzi) kuwo onke amashishini logama njengamashishini, uxinzelelo kunye nezinye izinto eziguquguqukayo azidluli kwimigangatho echazwe kumgangatho ofanelekileyo.
Kwizicelo zesakhiwo, akukho mahluko kwintsebenzo phakathi kwesi-erw kunye nombhobho wentsimbi engenamthungo. Ngelixa ezi zinto zimbini zinokuchazwa ngokungacacanga, ngekhe kwenzeke ukuba icace ingenamthungo xa i-piaped ye-piaped isebenza kakuhle.
