I ka HG,nā lepa i hoʻopaʻa ʻia, nā lehelehe palahalahaasocket welded flangesloaʻa nā kūlana like ʻole. ʻOkoʻa nā manawa kūpono, ʻo ia hoʻi, ʻo ka flange butt-weld flange ke anawaena paipu a me ka mānoanoa o ka paia o ka hopena o ka interface a like me ka paipu e welded, a ua welded pū nā paipu ʻelua.
Flange wiliwili palahalahahe anuu concave i oi iki aku mamua o ke anawaena owaho o ka paipu ma ka hookuonoono, a ua hookomoia ka paipu iloko.
ʻOi aku ka maikaʻi o ka hana kuʻi ʻana o ka kuʻi ʻana a ʻoi aku ka liʻiliʻi o ka corrosion.
ʻO nā flanges wili palahalahahoʻohana maʻamau no nā paipu haʻahaʻa a me waena,nā ʻāpana wili-wilihoʻohana ʻia no ka hoʻopili ʻana i nā pipeline medium a me ke kiʻekiʻe,nā ʻāpana wili-wiliʻO ka maʻamau he PN2.5Mpa ka liʻiliʻi, ʻo ka hoʻohana ʻana i ka welding butt e hōʻemi i ka neʻe ʻana o ke kaumaha.

Nā hiʻohiʻona onā flanges like ʻole:
ʻO ka flange wiliwili kumukūpono no ka liʻiliʻi anawaena, kiʻekiʻe puʻe, kiʻekiʻe wela hoʻohui paipu.
Kuʻi palahalahaua like ia me ke kuʻi ʻana me ka haku, ʻoki ʻia ke poʻo i loko o ke awāwa, a laila hoʻokomo ʻia ka paipu i loko o ka wili.
Hoʻoheheʻe socketʻAʻole ia he haku, i loko o ke kino flange e ʻoki pololei i kahi ʻāwīwī, e like me ka puka ma ka flange makapō, a laila ʻoki i kahi ʻāwī.
Kuʻi palahalahaʻoi aku ka maikaʻi ma mua o ka wiliwili kumu.
