He aha ka ʻokoʻa ma waena o ka flange welding socket and butt welding flange?

ʻO ka hoʻoheheʻe socket a me ka hoʻoheheʻe ʻana he mau ʻano hoʻopili maʻamau o ka flange a me ka paipu.ʻO ka hoʻoheheʻe ʻana ʻo ia ka hoʻokomo ʻana i ka paipu i loko o ka flange a laila wili ʻia, ʻoiai ʻo ka wili ʻana ʻo ia ka wili ʻana i ka paipu a me ka ʻili o ka ʻili.ʻO ke kumu wili o kasocket welding flangeʻAʻole hiki ke nānā ʻia i ka radiographic inspection, akā kapuʻu welding flangehiki.No laila, hoʻohana pinepine ʻia ka flange welding butt no ka poʻe me nā koi kiʻekiʻe no ka nānā ʻana i ka butt weld.

ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka flange butt-weld flange no ka hana ʻana a ʻoi aku ka maikaʻi o ka wiliwili ʻana ma mua o ka socket welding flange.Eia nō naʻe, ʻoi aku ka paʻakikī o ka nānā ʻana no ka flange butt-weld flange, a koi ʻia ka nānā ʻana i ka radiographic no ia mea, ʻoiai ʻo ka flange welding ʻae wale nō e pono ai ka nānā penetrant.No laila, hiki ke hoʻohana ʻia ka flange welding socket inā ʻaʻole pono ka wai i loko o ka pipeline i ka pae kiʻekiʻe.

Socket-weldednā lehelehehiki ke hoʻohana ʻia no nā paipu me ka helu haʻahaʻa haʻahaʻa a me ke anawaena liʻiliʻi, akā ʻaʻole maikaʻi ke koʻikoʻi post-weld o ka flange socket-welded, a ua maʻalahi ke komo ʻole ʻana, e hopena i nā māwae i ka paipu.No laila, ʻaʻole hiki ke hoʻohana ʻia ka flange socket-welded no nā paipu kūpono i ka corrosion a i ʻole nā ​​koi kiʻekiʻe no ka maʻemaʻe.A i ʻole ma ka pipeline kiʻekiʻe, ʻaʻole hiki ke hoʻohana ʻia ka flange welding socket no ka liʻiliʻi o ke anawaena, no laila e ʻōlelo ʻia e hoʻohana i ka flange welding butt i loko o ka hana me ka helu kiʻekiʻe a me nā kūlana lawelawe maikaʻi ʻole.

ʻO ke anawaena o ka flange welding socket he mea maʻamau hoʻokahi nui a hoʻokahi liʻiliʻi, ʻoiai ke anawaena o ka flange kuʻekuʻe wāwae e like a ʻokoʻa paha.ʻAʻole e loaʻa i ka flange wili kumu ka pilikia o ka beveling a me ka misalignment butt, a hiki ke hoʻololi ʻia ke kūlana kuʻi i ke kuʻi palahalaha.

ʻO ka maʻamau, hoʻohana ʻia ka flange welding socket no nā paipu ma lalo o 2 iniha.Hoʻohana nui ʻia ka flange welding socket no nā paipu paipu anawaena liʻiliʻi.ʻO kēia ʻano paipu he lahilahi ka mānoanoa o ka paia a hiki i ka misalignment a me ka corrosion, no laila ʻoi aku ka maikaʻi no ka socket welding flange.Hoʻohana pinepine ʻia nā flanges butt-weld no nā paipu ma luna o 2 iniha, no ka mea, ʻoi aku ka maikaʻi o ka pale ʻana o nā flanges butt-weld ma mua o ka loaʻa ʻana o nā flanges welding.
