Yazisa:

Kwicandelo leepayipi zentsimbi, kusetyenziswa iindlela ezahlukeneyo zokuwelda ukuze kufunyanwe unxibelelwano olusemgangathweni noluthembekileyo. Enye yezo ndlela yileiwelding ye-arc engaphantsi komhlaba ejikelezileyo(SAW), edlala indima ebalulekileyo ekuvelisweni kwepayipi ye-X42 SSAW. Njengenkokeli kushishino, iCangzhou Spiral Steel Pipe Group Co., Ltd., eyaziwa ngophawu lwayo lweWuzhou, inamathela kwimigangatho yamazwe ngamazwe kwaye iqinisekisa ukuba iimveliso zayo (kuquka ipayipi ye-X42 spiral submerged arc welded) ziyahlangabezana ne-API Spec 5L, ASTM A139, ASTM A252 kunye ne-EN 10219. Kule blog sijonga kwihlabathi elinomdla lepayipi ye-X42 SSAW, sigqamisa iingenelo zokusebenzisa i-spiral submerged arc welding ekuvelisweni kwepayipi ye-spirally welded.

Funda nge-Spiral Submerged Arc Welding (SAW):

Ukuwelda kwe-arc okufakwe kwi-Spiral submerged, okwaziwa ngokuba yi-SAW, yindlela ekhethekileyo yokuwelda esetyenziselwa ukwenza imibhobho efakwe kwi-spirally efana neUmbhobho we-X42 SSAWLe ndlela ibandakanya ukunyibilikisa i-wire flux kunye ne-base metal kusetyenziswa ubushushu obuveliswa kukutsha kwe-arc phakathi kwe-wire kunye ne-flux phantsi kwe-flux layer. I-flux layer isebenza njengomqobo okhuselayo, ithintela ungcoliseko lomoya ukuba lungaphazamisi inkqubo yokunyibilikisa. Le ndlela ineenzuzo ezininzi kunezinye iindlela zokuwelda.

Iingenelo zokuwelda nge-spiral submerged arc welding:

1. Ii-welds ezihambelanayo nezisemgangathweni ophezulu: Indlela ye-SAW esetyenziswa kumbhobho we-X42 SSAW ivelisa ii-welds ezifanayo nezikumgangatho ophezulu. Xa i-arc intywiliselwa kwi-flux, idala indawo elawulwayo ekhusela indawo yokunyibilikisa kwizinto zangaphandle, iqinisekisa ukuba iindawo ezidibeneyo nezithembekileyo ziyahambelana. Oku kuphumela ekuvelisweni kweepayipi ezidibeneyo ezijikelezayo ezinamandla angaqhelekanga kunye nokuqina.
