Kwintsapho ye-flange, i-flange ye-welding flanges iye yaba lilungu eliyimfuneko kwiinkqubo zemibhobho yoxinzelelo oluphantsi ngenxa yesakhiwo esilula kunye neendleko zoqoqosho. I-Flat welding flange, ekwabizwa ngokuba yi-lap welding flange, inobungakanani bomngxuma ongaphakathi ohambelana nedayamitha yangaphandle yombhobho, uyilo olulula lwangaphandle, kwaye akukho mibala entsonkothileyo, eyenza inkqubo yofakelo ibe lula ngakumbi.

I-flat welding flanges yahlulwe kakhulu yaba ziindidi ezimbini: i-plate flat welding kunye nentamo ye-flat welding. Ipleyiti uhlobo flat ukuwelda isakhiwo flange yeyona ilula kwaye ifanelekile kwiinkqubo imibhobho kunye namanqanaba asezantsi uxinzelelo kunye neemeko zokusebenza buthathaka, ezifana unikezelo lwamanzi civil kunye ne drainage, HVAC, etc. Intamo flat welding flange uyilwe ngentamo emfutshane, nto leyo engagcini nje ukwandisa ukuqina kunye nokomelela kwe-flange, kodwa iphucula amandla ayo okuthwala umthwalo, okwenza ukuba ikwazi ukumelana nombhobho ophezulu wokunyamezela. Isetyenziswa ngokubanzi kuqhagamshelo lwemibhobho yoxinzelelo oluphakathi noluphantsi kumashishini afana nepetroleum, imichiza, kunye negesi yendalo.

Indlela ye-welding ye-flange ye-welding flat ithatha i-fillet welds, elungisa umbhobho kunye ne-flange kunye ne-welds ye-fillet. Nangona olu hlobo lwe-weld seam alunakubonwa nge-X-rays, kulula ukulungelelanisa ngexesha le-welding kunye nokudibanisa, kwaye inexabiso eliphantsi. Ngoko ke, isetyenziswe ngokubanzi kwiimeko ezininzi apho ukusebenza kokutywinwa kungafuneki. Ukuveliswa kweeflange ze-welding flat kulandela imigangatho emininzi yelizwe, njenge-HG20593-2009, GB/T9119-2010, njl., ukuqinisekisa umgangatho kunye nokusebenza kweemveliso.
