Nā flanges ʻāʻī Weldʻo ia ke ʻano flange kaulana loa me ka hoʻolōʻihi ʻāʻī me kahi bevel weld ma ka hopena. Ua hoʻolālā ʻia kēia ʻano flange e hoʻopili pololei i ka paipu e hāʻawi i kahi pilina ʻano maikaʻi a kūlohelohe. I nā nui nui a me nā papa kaomi kiʻekiʻe, ʻaneʻane ʻo kēia wale nō ke ʻano o ka pilina flange i hoʻohana ʻia. Inā hoʻokahi wale nō kaila flange bored i loaʻa i nā noi hou, ʻo ka ʻāʻī weld kāu flange o ke koho.
Hoʻohui ka bevel weld i kahi wēlau paipu me kahi bevel like i loko o kahi pilina ʻano-V e hiki ai ke hana i kahi weld poepoe like a puni ka perimeter e hana i kahi hoʻololi i hoʻohui ʻia. ʻAe kēia i ke kinoea a i ʻole ka wai i loko o ka ʻaha paipu e kahe me ka palena liʻiliʻi ma o ka pilina flange. Nānā ʻia kēia pilina bevel weld ma hope o ke kaʻina hana weld e hōʻoia i ka like o ke sila a nele i nā anomalies.
ʻO kekahi hiʻohiʻona ʻike ʻia o ka flange ʻāʻī weld ʻo ia ka hub tapered. Hāʻawi kēia ʻano pilina i kahi hoʻolaha mālie o nā ikaika kaomi ma ke neʻe ʻana mai ka paipu a i ke kumu o ka flange, e kōkua ana i ke kū ʻana i kekahi o nā haʻalulu mai ka hoʻohana ʻana i kahi kaomi kiʻekiʻe a me kahi mahana kiʻekiʻe. Ua kaupalena ʻia nā pilikia mechanical i hāʻawi ʻia i ka mea kila keu ma ke neʻe ʻana o ka hub.
ʻOiai ʻo nā papa kaomi kiʻekiʻe e koi ana i kēia ʻano pilina flange ma aneane wale nō, hana pinepine ʻia nā flanges ʻāʻī wili me kahi alo hui ʻano apo (i ʻike ʻia ʻo ka maka RTJ). ʻAe kēia ʻili sila i ka ʻoki ʻia ʻana o kahi gasket metala ma waena o nā ʻauwaha o nā flanges hoʻohui ʻelua e hana i kahi sila maikaʻi loa a hoʻokō i ka pilina bevel wili ikaika kiʻekiʻe i ka hui paipu pressurized. ʻO ka ʻāʻī wili RTJ me kahi hoʻohui gasket metala ke koho mua no nā noi koʻikoʻi.
