ʻO ka flange welding socket he flange i wili ʻia me ka paipu kila ma kekahi ʻaoʻao a hoʻopaʻa ʻia ma kekahi ʻaoʻao.
ʻAno ili hoʻopaʻa:
ʻO ka helehelena hoʻokiʻekiʻe (RF), ka maka concave a me ka convex (MFM), ke alo a me ke alo (TG), ke alo hui pū (RJ).
Ka laulā o ka noi:
ʻO ka paila a me ka moku kaomi, ka aila, kemika, ka hana moku, lāʻau lapaʻau, metallurgy, mīkini, meaʻai a me nā ʻoihana ʻē aʻe.
Hoʻohana maʻamau i nā pipeline me PN ≤ 10.0MPa a me DN ≤ 40.

ʻO ka flange welding socket kahi ʻano o ka hoʻohui ʻana ma waena o ka flange a me ka paipu. ʻO ia ka hoʻokomo ʻana i ka paipu i loko o ka flange a laila wili. ʻAʻole hiki ke hoʻopaʻa ʻia ka junction welding socket i ka nānā radiographic. ʻO kasocket welding flangepono e hana i ka nānā ʻana i ka wā o ka lawe ʻana. No laila, hiki ke hoʻohana ʻia ka flange welding socket inā ʻaʻole pono ka wai i loko o ka pipeline i ke kiʻekiʻe welding grade.
Hiki ke hoʻohana ʻia ka flange socket-welded no nā paipu me ka helu haʻahaʻa haʻahaʻa a me ke anawaena liʻiliʻi, akā ʻaʻole maikaʻi ke koʻikoʻi post-welded o ka flange socket, a he maʻalahi ke komo ʻole ʻana, e hopena i nā māwae i ka paipu. No laila, ʻaʻole hiki ke hoʻohana ʻia ka flange welding socket no nā paipu me ka corrosion maʻalahi a i ʻole nā ​​koi hoʻomaʻemaʻe kiʻekiʻe, a i ʻole no nā paipu puʻupuʻu kiʻekiʻe, ʻaʻole hiki ke hoʻohana ʻia ka flange welding socket no nā paipu me ke anawaena liʻiliʻi.
ʻO ke anawaena o ka flange welding socket he mea maʻamau hoʻokahi nui a hoʻokahi liʻiliʻi, aʻo ke kumu wiliwili flangeʻaʻole e loaʻa ka pilikia o ka beveling a me ka misalignment, a hiki ke hoʻololi i ke kūlana kuʻiwili 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.
