I-flat welding flangeabakhiqizi bakulethela ukuze uqondei-flangeizinkinga zokugqwala
Imbangela yangaphandle eqondile yei-flangefuthi ukugqwala kwebholidi ubukhona bendawo edlayo phakathi kwei-flangeimvume, uma kungekho ukuvikelwa kwe-anti-corrosion coating,i-flangeindawo yensimbi nebhawodi ukuthintana ngqo namanzi nomoya kuzogqwala maduze. Wake wathatha ezimbiliama-flangeekuhlanganyeleni nge-adhesive tape noma ipayipi lepulasitiki izinyathelo zokuvunguza isonto lonke, ezama ukuvimbela umswakama wangaphandle kanye ne-sundries egebeni le-flange, indlela ngezinga elithile ingavimbela ukuhlukana phakathi kwegebe le-flange, kodwa umphumela wokulwa nokugqwala ku-flange izingxenye azinkulu, ngemuva kokusetshenziswa kutholwe izici ezintathu zenkinga:

1. Ngenxa yokwehluleka ukufeza uphawu oluphelele, endaweni enomswakama, kusekhona amanzi okujiya aqoqwe ku-flange clearance ngenxa yokuhluka kwezinga lokushisa. Uma ingenakuqedwa ngesikhathi, ukugqwala kuzosheshiswa.
2. i-pair of flange clearance kusuka kwangaphandle ivaliwe, kanye nokuvuza kwe-flange gasket, kulula ukukhiqiza ukuqoqwa kwegesi yemvelo, akusizi ekukhiqizeni okuphephile.
3. Ngemuva kwesikhathi sokusetshenziswa, i-tape yokunamathisela kanye nethubhu yepulasitiki idinga ukushintshwa njalo ngenxa yokuguga kwezinto.
Ngakho-ke, sebenzisa i-adhesive tape noma ipayipi lepulasitiki ukuze uvaleigebe le-flangekusuka ngaphandle ukwenza ukwelashwa kwe-anti-corrosion, umphumela osebenzayo awulungile, udinga ukuthola ubuchwepheshe obusha bokwelashwa kwe-anti-corrosion kanye nendlela yepayipii-flange.
