Umahluko phakathi kwe-ERW kunye ne-SAW ipayipi yensimbi

I-ERW ingumbhobho wentsimbi odityanisiweyo wokumelana nombane, umbhobho wentsimbi wokuxhathisa odityanisiweyo wahlulwe ngokutshintshiselana ngombhobho wentsimbi odityanisiweyo kunye nombhobho wentsimbi odityanisiweyo weDC ngeendlela ezimbini.

Ukuwelda kwe-AC ngokuhambelana nee-frequencies ezahlukeneyo zohlulwe kwi-welding ephantsi-frequency, i-IF welding, i-welding ye-ultra-IF kunye ne-high-frequency welding.I-welding High-frequency welding isetyenziselwa ukuveliswa kombhobho wentsimbi obhityileyo okanye umbhobho wentsimbi obunzima, ukuwelda okuphezulu kwi-welding yoqhagamshelwano kunye ne-induction welding.Ukuwelda kwe-DC ngokuqhelekileyo kusetyenziselwa umbhobho wentsimbi omncinci wobubanzi.Ngoko ke, ngokubhekiselele kwi-welding ebanzi, i-high-frequency welded pipe ifakwe kumbhobho we-ERW yinkqubo ye-welding ephezulu yokuvelisa imibhobho ye-ERW.I-ERW Longitudinal imveliso eqhubela phambili imveliso kwintsimi ye-oyile kunye nokugcinwa kwegesi kunye nokuthutha, ubunkokeli obusemgangathweni, umbhobho wensimbi wezoqoqosho ngakumbi.

I-SAW imibhobho yentsimbi imfutshane kwi-Summerged Arc Welding Steel Pipe, ekusetyenzisweni kwenkqubo ye-arc soldering ephantsi kwamanzi yokuvelisa intsimbi, inkqubo ivelisa uxinaniso oluphezulu kakhulu lwangoku, i-flux layer ukukhusela ilahleko ekhawulezayo yobushushu, kwaye igxininiswe kwi ummandla welding.I-arc weld ephantsi kwamanzi yomgangatho ophezulu, ukusebenza kakuhle kwemveliso, i-arc kunye nomsi iimpawu ezimbalwa zombhobho odibeneyo we-arc odibeneyo usetyenziswa ngokubanzi kwiinqanawa zoxinzelelo, ukuveliswa kwemibhobho, imiqadi, ulwelo oluphantsi loxinzelelo, imisebenzi yensimbi.Iimveliso eziphambili zemibhobho yentsimbi ye-SAW i-LSAW ye-Steel Pipe, i-Longitudinally Submerged Arc Welding Steel Pipe LSAW ipayipi yensimbi, kukusetyenziswa kwemveliso ye-arc ye-arc ye-welding ye-straight seam pipe.

Umahluko phakathi kwe-erw kunye ne-saw iron pipe

Njengoko i-ERW ipayipi yensimbi kunye ne-SAW ipayipi yensimbi kumbhobho ngexesha lokubumba, i-welding kunye nenkqubo iyahluka, ukuze iintlobo ezimbini zentsimbi yombhobho ekusebenzeni kukho ukungafani.

(1) Umgangatho wombhobho wentsimbi we-ERW ungaphezulu kunombhobho odityanisiweyo we-arc odityanisiweyo, umbhobho wentsimbi we-ERW ugudile, ugudile, umhle, umbhobho wentsimbi we-SAW wangaphakathi nangaphandle wokuqinisa i-weld.

(2) ERW steel umbhobho weld isiphene iintlobo ingaphantsi kombhobho yentsimbi isarha.Umbhobho wensimbi wabona i-solvent efakwe, iintlobo ezininzi zeephene, ngaphezu kweziphene zevolumu, kukho i-wire-line trap.I-ERW yensimbi ye-weld ye-weld defects kuphela i-wire-line kunye ne-welds echanekileyo, inkqubo yokuhlola kulula ukuyilandela, kunye neziphene ekubonakalisweni okuphezulu, kanye nje ukungabikho okucacileyo, i-ultrasonic ebonisa amandla, kulula ukuyibona.

(3) Umbhobho wensimbi we-ERW onxulumene nombhobho wentsimbi wesarha kwi-residual stress ratio uphantsi.Ukusukela oko uguqulo lombhobho we-ERW kwinkqubo yokuguqulwa ngokupheleleyo, kudityaniswe nesayingi ethe tyaba engumbhoxo, utshintsho oluthe nkqo kunye nentamo, ukwenza i-ERW yoxinzelelo lwentsalela yombhobho iba ncinci.Uvavanyo lomzimba lubonise ukuba iinkcukacha ezifanayo, umbhobho we-ERW wezinto ezifanayo emva kokusikwa ecaleni kwe-axis, i-axial kunye ne-transverse incisions encinci yokufuduswa kunombhobho odityanisiweyo we-arc odibeneyo.

(4) ERW Umbhobho ukusebenza jikelele efanayo, xa umbhobho isiphene, intsimbi scrap isigwebo, ukuvumela welding.I-SAW yentsimbi yombhobho ivunyelwe, kunye nokusebenza kombhobho welding kunye nokusebenza ngokubanzi akuhambelani, indawo ye-welding ejongene noxinzelelo lokuqhekeka kwe-corrosion.Iimvavanyo zibonisa ukuba uxinzelelo lwe-corrosion ukudinwa uvavanyo ERW umbhobho spiral submerged arc welding umbhobho ubude ngaphezu ubomi.
