Mu HG,ma flanges opangidwa ndi matako, flat-welded flangesndizitsulo welded flangeskukhala ndi miyezo yosiyana. Ntchito nthawi zosiyanasiyana, kuwonjezera, matako-kuwotcherera flange ndi m'mimba mwake chitoliro ndi khoma makulidwe a 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.
