Emndenini we-flange, ama-flange welding ayisicaba asephenduke ilungu elibalulekile lezinhlelo zamapayipi anengcindezi ephansi ngenxa yesakhiwo sawo esilula kanye nezindleko zokonga. I-flat welding flange, eyaziwa nangokuthi i-lap welding flange, inosayizi wembobo yangaphakathi ehambisana nobubanzi bangaphandle bepayipi, umklamo olula wangaphandle, futhi awekho ama-flange ayinkimbinkimbi, okwenza inqubo yokufaka ibe lula kakhulu.

I-flat welding flanges ihlukaniswe ngokuyinhloko ibe yizinhlobo ezimbili: i-plate flat welding kanye ne-neck flat welding. Isakhiwo se-flange se-flange se-welding silula kakhulu futhi silungele amasistimu wepayipi anamazinga aphansi okucindezela kanye nezimo zokusebenza ezithambile, ezifana nokuhlinzekwa kwamanzi omphakathi kanye ne-drainage, i-HVAC, njll. I-flange ye-flange ye-welding yentamo iklanywe ngentamo emfushane, engagcini nje ngokuthuthukisa ukuqina namandla e-flange, kodwa futhi ithuthukisa amandla ayo okuthwala umthwalo, okwenza ikwazi ukumelana nendawo yokucindezela okuphezulu. Isetshenziswa kabanzi ekuxhumekeni kwamapayipi anengcindezi ephakathi nendawo neziphansi ezimbonini ezifana ne-petroleum, amakhemikhali, negesi yemvelo.

Indlela ye-welding yama-flange welding welding isebenzisa ama-weld we-fillet, alungisa ipayipi kanye ne-flange ngama-welds amabili we-fillet. Nakuba lolu hlobo lwe-weld seam lungenakubonwa ngama-X-ray, kulula ukuluqondanisa ngesikhathi sokushisela nokuhlanganisa, futhi lunezindleko eziphansi. Ngakho-ke, isetshenziswe kabanzi ezimweni eziningi lapho ukusebenza kokubeka uphawu kungadingeki. Ukwenziwa kwamaflange okushisela ayisicaba kulandela izindinganiso kazwelonke eziningi, njenge-HG20593-2009, GB/T9119-2010, njll., ukuqinisekisa ikhwalithi nokusebenza kwemikhiqizo.
