ʻO Flange SOH i hoʻopaʻa ʻia i ke kila kila

ʻO ka ʻokoʻa ma waena o SO a me WN

1. ʻOkoʻa nā ʻano kuʻina hili:

ʻAʻole hiki ke nānā pono ʻia nā hili palahalaha, akā hiki ke nānā ʻia nā hili wili.ʻO ke ʻano o ka wiliwili ʻana o ka ʻāʻī ʻāʻī paʻa kuʻihao flange paipu a me ka flange he fillet weld, ʻoiai ke ʻano o ka wiliwili ʻana o ka ʻāʻī kuʻi ʻana o ka ʻāʻī a me ka paipu he girth weld;ʻo ka wili paʻa he ʻelua wili puʻupuʻu, A butt weld is a butt girth weld.ʻO ka ʻokoʻa ma waena o ka flange wili paʻa me ka ʻāʻī a me ka ʻāʻī kuʻi paʻa ʻole me ka ʻāʻī ʻo ka ʻāʻī kuʻi paʻa me ka ʻāʻī he wahi ʻē aʻe i loko o ka ʻāpana wiliwili paipu ma mua o ka flange kuʻi paʻa ʻole me ka ʻāʻī.ʻO ka flange he flange pālahalaha hoʻi, a ʻo ka luna me ka ʻole o ka flange he weld fillet palahalaha.ʻO ka weld ma waena o ka ʻāʻī kuʻi ʻana o ka ʻāʻī a me ka paipu hoʻohui i ka B-type seam, a ʻo ka weld ma waena o ka ʻāʻī ʻāʻī kuʻihao a me ka paipu hoʻohui ʻia no ka C-type seam, a me ka hoʻāʻo ʻole luku ʻana ma hope o ke kuʻi ʻana. ʻokoʻa.

2. He okoa ke kaomi inoa.

ʻO ke kaomi nominal o ka ʻāʻī paʻa kuʻi ʻana: 0.6---4.0MPa, ʻoiai ʻo ke kaomi nominal o ka ʻāʻī kuʻi ʻana o ka ʻāʻī: 1--25MPa pae, maopopo, ʻo ka ʻāʻī kuʻi paʻa paʻa ʻia ʻO ka haʻahaʻa haʻahaʻa.

3. Nā ʻano pili like ʻole:

ʻO ka ʻokoʻa nui loa o ka hoʻolālā ma waena o ka ʻāʻī kuʻi wili palahalaha ʻāʻī a me ka ʻāʻī ʻāʻī wiliwili ʻana ʻo ia ka pilina ma waena o ka nozzle a me ka flange.ʻO ka ʻāʻī kuʻikuʻi palahalaha maʻamau he nozzle a me kahi pili kihi flange., A ʻo ka ʻāʻī kuʻi ʻana me ka ʻāʻī ʻo ia ka hui pū ma waena o ka flange a me ka nozzle.

Hiki ke hoʻopili wale ʻia nā flanges wili palahalaha i nā paipu, ʻaʻole pololei i nā mea pono paipu welded;Hiki ke hoʻopili pololei ʻia nā flanges welded butt i nā mea pono paipu welded butt a pau (me nā kuʻekuʻe, tees, reducers, etc.), ʻoiaʻiʻo pū kekahi.

ʻOi aku ka ʻoi aku o ke koʻikoʻi o ka ʻāʻī kuʻi ʻana me ka ʻāʻī ma mua o ka ʻāʻī kuʻi ʻana me ka ʻāʻī, a ʻoi aku ka ikaika o ka kuʻekuʻe wāwae ma mua o ke kuʻi ʻana, ʻaʻole maʻalahi ka leak.

ʻAʻole hiki ke hoʻololi wale ʻia nā ʻāʻī wiliwili a me nā ʻāʻī kuʻi ʻana.Mai ka manaʻo o ka hana ʻana, ʻo nā flanges ʻāʻī welding (SO ka pōkole o SLIP ON) he anawaena nui i loko, ʻo ia hoʻi ke kaumaha haʻahaʻa a me ke kumu kūʻai haʻahaʻa.Eia kekahi, pono e ho'āʻo ʻia ka nominal diameter Neck butt welding flanges (WN ka abbreviation of WELDING NECK) ʻoi aku ka nui ma mua o 250mm, ʻaʻole pono e hoʻāʻo ʻia nā flanges, no laila he haʻahaʻa ke kumukūʻai.

Hoʻohana hou ʻia ka wili ʻāʻī palahalaha i nā hoʻokomo ʻaila i lawe ʻia mai, e like me ka S0 maʻamau ʻAmelika, hoʻohana ʻia ka flange welding butt me ka ʻāʻī no nā media pōʻino loa.
