Mu HG,matako-welds flanges, flat-welded flangesndizitsulo welded flangeskukhala ndi miyezo yosiyana. Ntchito nthawi zosiyanasiyana, kuwonjezera, matako-kuwotcherera flange ndi m'mimba mwake chitoliro ndi makulidwe khoma la mawonekedwe mapeto ndi chimodzimodzi chitoliro kuti welded, ndi mipope awiri ndi welded komanso.
Flange kuwotcherera flangendi concave nsanja yomwe ndi yaikulu pang'ono kuposa awiri akunja a chitoliro pa mawonekedwe, ndi chitoliro anaikapo mmenemo.
Kuwotcherera kwa matako kuli bwino ndipo dzimbiri ndi zazing'ono.
