I loko o ka ʻohana flange, ua lilo nā flanges wili palahalaha i lālā pono ʻole o nā ʻōnaehana pipeline haʻahaʻa haʻahaʻa ma muli o ko lākou ʻano maʻalahi a me ke kumukūʻai waiwai. ʻO ka flange welding flat, ʻike ʻia hoʻi ʻo ka lap welding flange, he puka i loko e like me ke anawaena o waho o ka pipeline, kahi hoʻolālā maʻalahi o waho, ʻaʻohe flanges paʻakikī, e maʻalahi ke kaʻina hana.

Hoʻokaʻawale nui ʻia nā flanges wili palahalaha i ʻelua ʻano: plate flat welding a me neck flat welding. ʻO ke ʻano pāpaʻi paʻa paʻa paʻa paʻa ka mea maʻalahi a kūpono i nā ʻōnaehana pipeline me nā pae haʻahaʻa haʻahaʻa a me nā kūlana hana maʻalahi, e like me ka lako wai kīwila a me ka hoʻoheheʻe ʻana, HVAC, a me nā mea ʻē aʻe. Hoʻohana nui ʻia ia i ka hoʻopili ʻana i nā pipeline medium a me ka haʻahaʻa haʻahaʻa i nā ʻoihana e like me ka petroleum, kemika, a me ke kinoea maoli.

ʻO ke ala wili no nā flanges welding palahalaha e hoʻohana i nā welds fillet, kahi e hoʻoponopono ai i ka paipu a me ka flange me nā welds fillet ʻelua. ʻOiai ʻaʻole hiki ke ʻike ʻia kēia ʻano weld seam e nā X-ray, maʻalahi ke hoʻohālikelike ʻia i ka wā wili a me ka hui ʻana, a he haʻahaʻa ke kumu kūʻai. No laila, ua hoʻohana nui ʻia i nā kūlana he nui ʻaʻole koi ʻia ka hana sila. ʻO ka hana ʻana o nā flanges welding palahalaha e hahai ana i nā kūlana aupuni he nui, e like me HG20593-2009, GB / T9119-2010, etc., e hōʻoiaʻiʻo ana i ka maikaʻi a me ka hana o nā huahana.
