Zombini ukuxhathisa koMbane okudityanisiweyo (i-RW) kunye ne-seamless (SMLS) iindlela zokwenza umbhobho wentsimbi sele zisetyenziswa amashumi eminyaka; ngokuhamba kwexesha, iindlela ezisetyenziselwa ukuvelisa nganye ziye zahambela phambili. Ngoko ke yeyiphi engcono?
1. Ukuvelisa umbhobho odityanisiweyo
Umbhobho odityanisiweyo uqala njengeribhoni ende, ebhijelweyo yentsimbi ebizwa ngokuba yi-skelp. I-skelp inqunywe ubude obufunwayo, okubangela ukuba ishidi elixande elixande. Ububanzi beziphelo ezimfutshane zelo shiti buya kuba sesangqa sangaphandle sombhobho, ixabiso elinokusetyenziselwa ukubala idayamitha yangaphandle.
Amashiti angamaxande atyiswa ngomatshini ogoqayo ogoqayo amacala amade ukuya kwelinye, enze isilinda. Kwinkqubo ye-ERW, umbane we-high-frequency current ugqithiswa phakathi kwemida, ubangela ukuba inyibilike kwaye idibanise kunye.
I-advanteji yombhobho we-ERW kukuba akukho zintsimbi ezidityanisiweyo zisetyenziswayo kwaye i-weld seam ayinakubonwa okanye ivakale. Oko kuchasene ne-double submerged arc welding (DSAW), eshiya ngasemva i-weld bead ecacileyo ekufuneka isuswe ngokuxhomekeke kwisicelo.
Iindlela zokwenziwa kwemibhobho edityanisiweyo ziye zaphucuka ngokuhamba kweminyaka. Mhlawumbi eyona nkqubela phambili ibalulekileyo ibe kukutshintshela kwimisinga yombane ekwi-frequency ephezulu yokuwelda. Ngaphambi koo-1970, kwakusetyenziswa i-low-frequency current. Imithungo ye-Weld eveliswe kwi-ERW ye-low-frequency yayithandwa kakhulu kukuhlwa kunye nokusilela komthungo.
Uninzi lweentlobo zemibhobho edityanisiweyo zifuna unyango lobushushu emva kokwenziwa.
2. Ukuvelisa umbhobho ongenamthungo
Imibhobho engenamthungo iqala njenge-cylindrical hunk yentsimbi ebizwa ngokuba yibillet. Ngelixa kushushu, billets zigqojozwa embindini kunye mandrel. Isinyathelo esilandelayo kukuqengqeleka kunye nokwelula i-billet engenanto. I-billet igqitywe ngokuchanekileyo kwaye yoluliwe ide idibane nobude, ububanzi kunye nobukhulu bodonga njengoko kuchazwe ngumyalelo wabathengi.
Ezinye iintlobo zemibhobho engenamthungo ziyaqina njengoko zisenziwa, ngoko ke unyango lobushushu emva kokwenziwa alufunwa. Abanye bayalufuna unyango lobushushu. Qhagamshelana nenkcazelo yohlobo lombhobho ongenamthungo ocinga ukuba uyakufuna na unyango lobushushu.
3. Iimbono zembali kunye namatyala okusetyenziswa kwe-welded vs. i-seamless steel pipe
I-ERW kunye nemibhobho yentsimbi engenamthungo zikhona njengezinye iindlela namhlanje ubukhulu becala ngenxa yeembono zembali.
Ngokubanzi, umbhobho odityanisiweyo wawuthathwa njengobuthathaka ngenxa yokuba wawubandakanya i-weld seam. Umbhobho ongenamthungo wawungenasiphene kulwakhiwo kwaye wawuthathwa njengokhuselekileyo. Ngelixa kuyinyani ukuba umbhobho odityanisiweyo uquka umthungo owenza ube buthathaka ngokwethiyori, ubuchule bokuvelisa kunye nerejimeni zokuqinisekisa umgangatho nganye iye yaphucuka ukuya kuthi ga kwinqanaba apho umbhobho odityanisiweyo uya kusebenza njengoko unqwenela xa ukunyamezela kwawo kungagqithiswanga. Nangona i-advanteji ebonakalayo icacile, i-critique ye-piping engenamthungo kukuba inkqubo yokuqengqeleka kunye nokwelula ivelisa ubungakanani obungahambelaniyo bodonga xa kuthelekiswa nobukhulu obuchanekileyo bamashiti ensimbi amiselwe ukuwelda.
Imigangatho yoshishino elawula ukwenziwa kunye nokucaciswa kwe-ERW kunye nombhobho wentsimbi ongenamthungo usabonisa ezo mbono. Umzekelo, imibhobho engenamthungo iyafuneka kuxinzelelo oluphezulu, ubushushu obuphezulu kwizicelo zeoyile nerhasi, ukuveliswa kwamandla kunye namashishini axuba amayeza. Imibhobho edityanisiweyo (okuyixabiso eliphantsi ukuyivelisa kwaye efumaneka ngokubanzi) icaciswa kuwo onke amashishini ukuba nje ubushushu, uxinzelelo kunye nezinye izinto eziguquguqukayo zenkonzo zingagqithi kwiiparamitha eziphawulwe kumgangatho osebenzayo.
Kwizicelo zesakhiwo, akukho mahluko ekusebenzeni phakathi kwe-ERW kunye nombhobho wentsimbi ongenamthungo. Ngelixa ezi zimbini zinokuchazwa ngokutshintshanayo, ayizukwenza ngqiqo ukucacisa ngokungenamthungo xa umbhobho odityanisiweyo wexabiso eliphantsi usebenza ngokulinganayo.
4. Sibonise ii-specs zakho, cela i-quote kwaye ufumane umbhobho wakho ngokukhawuleza
